The Truth About Polystyrene – Is It Useful Or Harmful?

Saturday, January 14th, 2012

Polystyrene is one of the most commonly utilized plastics, with worldwide production totaling to billions of kilograms each year. Polystyrene has impressive utility and it is ubiquitous in the packaging and construction industry used as structural component or for insulation purposes. Products made out of the said polymer are nearly ubiquitous as they can be molded into disposable cutlery, food containers, and beverage cups. Molded polystyrene are used in CD jewel cases, license plate frames, and other objects where fairly rigid plastic is desired. You can find them in a variety of colors as well.

There are two primary kinds of polystyrene, and these are the EPS and the XPS. EPS stands for expanded polystyrene and it is produced from solid beads of the said polymer which undergo a process of expansion by the introduction of pentane gas during the manufacturing process. Expanded polystyrene sheets are also called beadboards although they can also be molded to specifications to form blocks, or customized shapes for building insulation and packaging industries.

XPS has a smooth surface and is stronger than EPS. It has generally higher density and strength than expanded foam. Because of the dense configuration of an extruded polystyrene sheet, those who use them for insulation are guaranteed of minimal air leaks. Their rigidity and strength makes it ideal for engineering applications as well. Styrofoam, a trademark of the Dow Chemical Company for XPS foam, has become a proprietary eponym for extruded polystyrene products.

Polystyrene is well-received by the public because of its utility. When used for residential and commercial construction, polystyrene sheets help create quiet, and energy efficient spaces since air leaks and heat loss are minimal. It also is more resilient against damage due to insects and moisture, providing better structural integrity compared to wood frame construction. In most cases, buildings that make use of polystyrene have higher resale value. For food-contact applications, the said plastic is very hygienic and do not add considerable weight to the total package. When used for packaging, the said material can adequately protect fragile or shock-sensitive items. Regardless of application, polystyrene products are less expensive to buy.

One of the disadvantages with using polystyrene is that it is manufactured from petroleum, thus the production of polystyrene-based products contributes to the rapid depletion of our fossil fuel stores. Another drawback to polystyrene use is that it its production contributes to ozone depletion and consequently to climate change due to the hydrofluorocarbon compounds extensively used during the manufacturing of XPS products. There are also worries of a substance from foam containers called as styrene migrating onto the food items. Styrene is toxic and is associated with the development of certain cancers. Lastly, no known microorganism has yet been shown to biodegrade polystyrene, and as such remain to be a significant form of pollution in the outdoor environment.

Polystyrene is a popular kind of plastic with impressive utility and versatility. Polystyrene sheets can be molded and utilized as engineering, and packaging materials. Follow this link to learn more about the advantages and disadvantages of polystyrene sheet use.

Surround Sound Fundamentals

Thursday, January 5th, 2012

You can never forget surround sound after you have listened to it. Surround sound is the sound delivery system that has long been used in cinemas, so if you have been to the cinema over the last 15-20 years you will know what I mean. These days, it is inexpensive enough to have in your home and many people do have it.

Surround sound is basically the next step up from quadraphonic or four-speaker sound. This form of playing back sound makes certain recordings sound more realistic. For instance, if you were watching Formula One racing or if you were watching a war movie, you would hear cars or bombs all around you because the sound would be coming from speakers placed all about you.

However, it is not merely a question of placing loudspeakers all about you, the whole sound has to be spread among channels and some channels should just be played over one speaker.

It is a sophisticated set up, if the recording was made well. Surround sound will improve your experience of video games, films and music (some types more than others).

Surround sound systems are described in two numbers usually, so you may see 5:1. This means that there are five standard loudspeakers and a sub woofer. Four speakers are placed at the four corners of the room and one under the screen; the sub woofer is put at the back in the centre of the wall.

After that, there is 6:1, with an extra speaker placed above, below or along slide the sub woofer. There is 7:1, where three loudspeakers are put along the left and right walls, one under the screen and a sub woofer and so it goes on.

You can, obviously, set the loudspeakers up to suit the shape or acoustics of your room, but these are standard configurations and you could go on adding speakers and sub woofers until your heart is content.

The best way of setting up a good surround sound system is to go for a home theatre environment. Home theatre is based on the DVD player. If you make sure that this player is designed for home theatre, it will automatically be ready for surround sound, but check how many different audio output channels it will sustain.

If your system is going to be used for gaming as well, you can use the Xbox as your DVD player according to some people. It is worth looking into to see if it will fit the bill. A home theatre system could be created in a spare room, but that is not always handy for listening to music.

In that case, you could either have the home theatre in the living room or run a different set of loudspeakers to the living room with a switch to be able to route the sound from room to room independently

When you are thinking of building your surround sound, purchase the best five loudspeakers that you can afford rather than seven cheap loudspeakers, but make certain that you will be able to buy more of the same speakers later so that you can build up your surround sound system as you get more cash.

Fire Safety In The Home

Tuesday, December 20th, 2011

If you think about it, it makes sense for every home to have its own, custom-made fire safety policy. After all, each hotel has one and so does every workplace and public building, so why should your family and home not be on an even footing with them? But how many families have one. I personally do not know of any. It is weird that we appear to undervalue our nearest and dearest such a lot.

So where should you go to find a fundamental fire safety plan? There are many places. You should be familiar with the fire safety scheme at your workshop for a start. Otherwise, you could go to you library or any public office and read theirs.

You will almost certainly have to adapt any public fire safety policy you read to home life, unless you intend handing out RFID tags or having a doorman to check everyone in and out. This is a difficult point. How do you know who is in and who is out in a big house?

The Fire Department will also be able to give you fire safety tips. In some countries, the fire department is glad to visit private homes free of charge to offer advice on how best to safeguard one’s family.

Smoke Detectors: There should be a smoke detector outside the kitchen (inside if nobody ever burns the toast) and on every stairs landing. They ought to be hardwired together, so that if one goes off they all go off and they could be coupled to the house main burglar alarm siren too. They ought to also be wired into the house mains electricity system with individual battery back ups.

Emergency Lighting: there ought to be emergency lights pointing towards the nearest ground floor exit. These ought to be mains and battery powered as well. Think about putting luminous strips on each (top) tread of the stairs, because you do not want individuals falling down the stairs in their dash to escape in the dark.

Fire Extinguishers: there ought to be a fire extinguisher in the kitchen and garage and on each landing too. Think about putting a small one in each bedroom.

Personal Fire Safety Kit: it is a wise precaution to place some sort of kit in every bedroom. This kit could contain: a fire blanket, safety goggles and a hand bell. A fire-resistant blanket against the heat; goggles so you may see in the smoke and a bell to warn the rest of the house if the alarms do not ring or to call for help if you become trapped.

Intumescent Strips: you could automatically seal off parts most likely to catch fire with intumescent strips. You cut a groove in an hour-fire check door with a router all around the edge and insert a strip. At a certain temperature, the strip expands very quickly, sealing the door shut and localizing any fire. These doors must be shut first (door closers) naturally.

Make sure that everybody knows where to muster and phone missing family members. Hang your safety policy in each toilet so that even guests have the chance to read it and you will have the safest home on the block.

Should You Have A Weather Radio?

Tuesday, December 13th, 2011

There are radios that are especially for tracking the weather. Not everybody has to have one of these dedicated devices, although we are all fascinated by the weather. However, the amount of information given out by most radio stations is enough for the majority of us. So what type of people would benefit from a so-called weather radio?

Weather radios are most appropriate for people living in areas where extremes of weather can and do take place on fairly a regular basis. If the region where you live is subject to hurricanes, tornadoes and flash floods or even severe storms, you are a likely candidate for a dedicated weather radio. Particularly if you have to travel away from home while an extreme weather event might happen.

All radio stations give weather news and weather warnings, but not all radio stations will suspend a programme to give ‘stop press’ updates on impending severe weather conditions. It is the same with television stations, not all of them will interrupt the highlight film of the evening to report on an approaching storm. Some of the smaller stations are not even subscribed to these types of weather reporting services.

However, it is not only people who live in areas of possible extreme weather who may benefit from these weather radios. People who carry out specialist activities and specialized jobs need more specialized weather reports too. For example, deep sea fishermen, sailors, farmers, mountaineers, hikers and backwoodsmen need to know if severe weather is on the way.

A lot of weather radios are not only capable of broadcasting news about the weather. Many of them have a built-in AM/FM radio as well and some will even act as alarm clocks. Some are mains only, whilst others are battery powered, wind-up or solar powered.

Some are large, but most are designed to be carried easily in an ordinary backpack and may have earphones as well so that you can listen to a transmission during a howling gale.

If you are just sitting at home, you may feel safe enough with the local television or radio station on, but if you have to go outside while there is a risk of severe weather, a weather radio is very reassuring.

There are plenty of types and styles of weather radio to suit all needs, but a battery or wind up radio are the most reliable if you are away from a mains power source such as at sea or in the woods.

You will be able to find weather radios in a good number adventure or camping shops and in many chandlers. It is also easy to find these dedicated radios on line particularly on eBay or Amazon.

Weather radios are not expensive to buy, but some models can eat up batteries so always take a couple of extra sets of batteries if you are going off the beaten track.

Bouncy Houses, Bouncy Castles And Moonwalking

Monday, December 5th, 2011

Why would one group of people, or one country call them bouncy houses, another call them bouncy castles and the industry call it moonwalking? It is an interesting question, is it not, if you know what I am talking about. In fact, I mean those large inflatable children’s playthings that you see at school fetes and some children’s parties.

In America, where they were thought of in the Sixties by John Scurlock of Louisiana. Like numerous inventions, the notion came to him by accident. Scurlock was an engineer experimenting with inflatable roofs for tennis courts and garages and one day he saw that a few of his employees were having great fun bouncing around on an inflated roof that was laying on the ground.

He had an notion and eleven years later, in 1968, his wife, Francis, was running the first bouncy house rental firm in the world. Eight years later, he opened the world’s first dedicated bouncy house factory and ten years later again, their son, Frank, opened the world’s first fun park devoted to only inflatable toys called Fun Factory.

Lots more followed. Frank also took the bouncy house distribution and rental network nationwide. At first these inflatable toys did not have sides or a top, but this caused a couple of minor difficulties in that kids bounced off the deck onto the grass (or concrete) and the bouncing children were sometimes exposed to the full force of the sun, which put them art risk of exhaustion.

The current most well-liked bouncy house design of three inflatable walls and an inflatable roof came to pass fairly soon after the issues were identified. In fact there are variations on the answers that were found. In the USA, the sides of the moonwalk are usually made of netting supported by inflatable columns, whereas in the UK frequently three of the sides are inflatable. Observation is carried out from the front of the bouncy house.

These inflatable bouncy houses are mostly made of reinforced PVC, nylon or vinyl and the whole structure is filled with gas, which gives more support than air. A proper bouncy house is continually being pumped up by a fan or two so that minor punctures do not have an effect on the pleasure of the kids.

Cheaper types that are blown up once and left, a bit like a lido or airbed, are forbidden to be rented out in the USA and the UK although they can be used for private parties at home.

Most Western countries have associations in place that regulate businesses that seek to manufacture or rent out bouncy houses. This is great for safety reasons, so if you are thinking of buying or hiring a bouncy house or bouncy castle for one of your parties, find out the name of the regulatory body first and check whether the company you like is registered.

In the USA and the UK, the names of the companies and their products are listed on the web site so that you can check quite quickly.

Oh, and why bouncy houses, bouncy castles and moonwalking? America has never had any castles and walking on the airbed feels as if you are walking with less gravity.

Buying Your Digital Camera

Sunday, December 4th, 2011

Digital cameras are here to stay, so whether you want to take professional quality photos or merely a few holiday and family snaps a couple of times a year, you will have to become used to them.

The happy news though is that the digital functions accessible are implemented in the same way on all digital cameras, so once you have learned how to use the contrast function on one camera, you will be able to use it on all digital cameras.

This is not to say that these features are equally efficient on all cameras or that they will be accessed in the same manner on all cameras though. A costly camera manufactured by a decent manufacturer will almost certainly be better than a cheap point-and-click camera built into a mobile phone, but you would expect that anyway.

Most digital cameras have dozens and dozens of features to control specialist aspects of lighting, most of which most amateur snappers have no clue about and usually they do not need to know about them either. Lots of these features are accessible in picture manipulation software, so they are just duplicated in the camera, where most people do not use them.

The first tip for purchasing a camera is not to judge it by its looks. Novices are frequently impressed by how the camera looks rather than what it can do. This is usually because they do not understand the features but they like their camera to be the size of a packet of cigarettes. So before you go to buy a digital camera, take some time to acquaint yourself with the standard capabilities of a digital camera.

The first term to be aware of is megapixels. Digital images are made up of dots like a TV picture. The more dots the higher the resolution and the better the picture. The better the image, the more expensive the camera. So, what sort of quality pictures do you need and how much can you afford to spend?

Most digital cameras are packed with features, but do you truly need them all? If you intend using the photo manipulation software that comes with most cameras, then you do not really need the features built into the camera too. If you do not require professional quality pictures to print off on paper, why pay for them? Just purchase a camera with only the features that you will use.

You can often buy a less feature-rich camera in the sales, which are meant to clear out old stock before the latest models come out. The latest models will have more functions, so you could win all round by purchasing last year’s model at a knock-down price.

Two functions that are worth having are a USB cable and connection and a memory expansion slot. The USB connection will allow you to easily upload your photos to your computer for manipulation and distribution and the external memory will permit you to take more photographs than the camera’s RAM would usually permit.

How To Care For Your Fish Pond

Saturday, July 30th, 2011

Do you like the sound of running water? Do you find the sound relaxing? Well, you can easily produce the sound of moving water in your own garden. You can put in a fish pond or a water garden. So, if you think that your garden needs landscaping, it might be a good idea to think about a fish pond or water garden.

People think that a fish pond takes lot of looking after, but that is not inevitably the case. The fact is that the larger the fish pond, the less effort you have to put into it. This is because a large pond can create its own ecosystem, whereas a small fish pond requires help.

The ways that you can help a small fish pond be a good environment for your fish are as follows:

Pond Filters – use a pond filter with a good pump. Do not forget that you could use a solar powered pump. It will save on the environment and on your wallet. You should use a pond filter on a small pond, because the ecosystem cannot cope with all the plant waste of a small ornamental pond on its own. A pond pump will feed the filtration system and a waterfall or fountain if you want.

Your pond filtration system should be left running twenty-four hours a day, but you can not just set it and forget it. Check that the pump is running daily and keep the filter as clean as needed for it to do its job. You may find that you have to clean it two or three times a week in the summer and autumn but only once a week in the winter and spring.

Leaf Netting: stop leaves from clogging up your pond in the autumn. The net should be poised a foot or so above the pond to prevent autumn leaves falling into the water and rotting.

Feeding: all fish should be given fish food, not bread or scraps. Some fish need specific fish food in order to maintain their colour. When you buy your fish, the salesperson should inform you what they eat. In general, the larger the pond the less hassle feeding becomes as they will eat natural food like insects, grubs, larvae and flies.

Fish need less food in the winter when they become semi-dormant and live off the fat reserves that they built up in the warmer months, so give food often in the summer and autumn, but less often in the winter. You must look to see if surplus food is left floating on the surface.

Winter: make certain that there is a hole in the ice so that the water can take in oxygen and the fish can feed if they want to. You can buy a floating de-icer or some people float a round football in a hoola-hoop, which seems to do the trick unless the temperature gets very low.

In fact, the hoola-hoop is a good idea all year round really. If you place the food in the hoop, it remains in one place and you can see if you have given too much. It also makes a nice site to see all the fish feeding in a shoal.

Electrical Safety Pointers

Saturday, July 23rd, 2011

The accidents associated with electricity are caused by electrocution. Electrocution can result in: minor shocks, which can cause other accidents like falls; medium shocks, which can cause burns and even critical burns and major shocks which can result in death in the same way as in some American prisons.

The victim can receive an electric shock by coming into contact with a live wire or by the electricity from a live source arcing out – essentially finding earth through that person’s body. The majority of electric shocks are not serious and are over before you know what has happened but they are frightening afterwards.

A fall ensuing from a mild electric shock probably has greater potential to be fatal than the shock itself. For instance, if you were changing a light bulb from a chair and you reckoned that the power was off, yet it was not, you may receive a short sharp shock, and it could cause you to fall off the ladder and break your back.

On the other hand, high voltage electric shocks can cause burns deep in human tissue while leaving just minor signs of the injury on the outside. It is very critical not to become complacent about electricity, because, like the open sea, it does not suffer fools gladly. Here are a couple of electrical safety pointers to help keep you safe.

1] Always inspect power tools for damage and broken plugs or frayed cords before use. You may have damaged it last time you used it yet got away with it that time

2] If you are working in the same area as others, especially on a building site, do not leave your cables running across the floor – attempt to tape them to a wall or a bench, because workers may step on them, run wheel barrows across them or spill water on them.

3] Always use the correct gauge cable and fuse for your equipment.

4] If anything gets warm when you are using it, be aware that it might be a sign of an approaching difficulty. Leave warm equipment or sockets to cool down, if it occurs again, get them checked by an electrician. Do not over load electrical sockets.

5] Strive to use a dry wooden ladder if you are working near cables, because wood does not conduct electricity.

6] If you are using any apparatus that produces heat or strong light, do not direct it on anything that could catch fire.

7] Install fast-reacting circuit breakers between your apparatus and the source of electricity to reduce the shock that you may get. These devices sense a faulty earth and switch the appliance off in milliseconds.

If your appliance or electrical equipment has a button for checking the earth, use it every day and if you are going to work on a light socket, an electrical socket or the fuse box, test it first with one of those electrical screwdrivers with a small bulb in it. You poke it into the circuitry and the bulb lights up, you have just had a narrow escape. Be more cautious next time!

Fire Prevention And RV’s

Friday, July 22nd, 2011

An RV – a Recreational Vehicle – is similar to a house on wheels. It is the landlubber’s counterpart to a barge, you can live in it while travelling the country. You are as free as a bird in your RV as you do not need to go where the hotels are located.

Having said that, the RV is also a mobile bomb carrying gallons of petrol or diesel and bottles of propane or calorgas. Therefore, you need to have clear safety procedures in place and you need to know and follow them. Fire safety is of the highest importance to the conscientious RV driver.

Fire extinguishers are rated as either A, B, C, or D, which explains the sort of fire that they may be used to fight. If you did not already know it, you should not simply squirt any fire extinguisher at any sort of fire. Using the wrong extinguisher on a fire can escalate the danger, so be careful.

Having said that, some fire extinguishers can be used on different kinds of fires, so it is possible to find extinguishers rated as AB, BC and even ABC. The National Fire Protection Association (NFPA) recommends that all RV’s carry a BC rated extinguisher near the main exit from the RV. A BC type extinguisher should be used to combat fires starting from flammable liquids and gases – just what an RV driver needs.

The key point about a fire extinguisher of the correct type is that it has to be in the right position. It is no use having a fire extinguisher if you cannot get to it to fight the fire when it breaks out.

If the diver’s cab is detached from the sleeping compartment, you should carry an extinguisher in the cab too. Store one outside the RV and one inside it too.

It is a good idea to develop a fire prevention and fire safety course before you set out and be sure that your companions know how best to prevent and how best to deal with fires in the RV. Fires in restricted spaces such as an RV, a caravan or a boat are especially terrifying and perilous, because you are more likely to be overcome by the smoke and gases than in a house. Finding your way out of an unfamiliar RV that is full of smoke is not as simple as you might think.

You should also instruct your companions how to operate a fire extinguisher – after all, most individuals have never utilized one. Keep in mind the word ‘PASS’, which stands for ‘Pull, Aim, Squeeze and Sweep’.

This means, pull the pin, aim at the base of the fire, squeeze the handle and sweep the spray across the base of the fire until it is out. The best distance from the fire is about eight feet, but this is not always possible.

If you have to make a decision between saving the vehicle or endangering your life, let the RV burn, after all, it is insured. Never put yourself or others at risk for the sake of property.

Your Koi Pond After A Storm

Wednesday, July 20th, 2011

A storm can be stressful for your outdoor fish, especially for large koi carp, which, being large, possibly do not have many places to hide. However, if you have designed your koi fish pond well, you will have taken this into account when your constructed the pond. Likewise, the pond must be deep enough for your fish to be able to get well below the choppy surface level.

If you prepared for the storm, you probably put a net over the fish pond, so the first thing you ought to do after the storm is clear up any fallen debris and take away the net, so that you can get a good look at your fish and what happened to them. They may be a bit stressed, so move unhurriedly and try hard not to frighten them. Stress is a killer in the animal world as well as in ours.

Did you take the additional precaution of sand-bagging the rim of your pond to stop it over-flowing and the fish swimming away? If so, take away the sand bags, so that you can get a better look.

Now you can get a good look at the upheaval, if there is any. Use a net to quietly skim off any leaves that have blown under the netting and onto the pond. If any plants have been uprooted, put them back where they should be. In general, put the pond back as it used to be, so that the fish feel at home. Again, move unhurriedly and try not to put your fish under any more stress.

If you have to carry out major structural repairs, you could place your koi in a child’s plastic paddling pool until you can sort the issue out. Put the pool in a shaded area and fold the netting over it several times so that the fish can not get out and cats and birds cannot get in. If you can aerate the pool with a pump so much the better.

Place a few plants in there with them for cover and feed sparingly. if the repairs will take a long time, you could ask your local pet store to take them away for a week or whatever. You will have to pay board and lodgings, but it is preferable to losing your prized koi carp.

Once any repairs have been carried out, you ought to check the water quality, which could have been affected by debris dropping into the pond or by your repairs. Rain, especially acid rain, can have quite an effect, particularly if it rained for a long time.

First test the water for nitrates. If the levels are unacceptable (see the testing kit for details), you should normalize them. If the levels are extremely high, first remove the plants from the water.

Then analyze the KH levels. If they are low, say, below 100, then you could add a cup of baking soda per 1,000 gallons of water and check again. Whatever you do, the fastest way to de-stress your fish is to reinstate their environment to what it used to be with sparkling water to swim in.
