Q:why is plastic apparatus sterilized?
well I suppose it depends on WHICH plastic apparatus you are speaking of if it were medical like a catheter or syringe I would want it sterilized after manufacture and before use
Q:Tongue jewelry? Metal, Plastic?
i have my tongue pierced and i always wear steel but u can wear a plastic one after its fully healed. the only reason i wear steel all the time is cuz plastic iritates my tongue for some reason.lol. but u can get all colors and even get them with sets in them. u will find what is comfortable just try a bunch of different ones and see what u like. they arent very expensive. u can change it all the time after its healed just dont take it out for long cuz it will close up. tongues heal really fast.
Q:Is cheese made of plastic?
If you get fake cheese then yes it's made of plastic, but the real edible stuff comes from happy cows and no plastic. Not scared of blood on the first and third wednesdays of the month but I am on all the other days (I wear my superman costume on the first and third wed.)
Q:Plastic products 2 can hold hot things?
At present, many plastic products, with colorless and transparent special food bags of food is good, no other harm, opaque, or colored plastic bags are not packaged food, agricultural film is seemingly transparent, colored, is very light. It is not a packaged food product.
Q:can you make plastic stuff without a factory?
You can obtain just the plastic pellets and then use them in your prototype. Most industrial plants that use plastics don't manufacture it themselves, they purchase pellets from a supplier.
Q:what are the disadvantages of using plastic?
Most plastic bags are produced using oil. Oil drilling is harmful to the environment and our addiction to oil is making our nation less secure, while damaging our economy. (Though of course there are other problems with security and economy.) In addition, plastic bags that are not recycled will eventually end up in a landfill or in the ocean. Plastic does not even begin to biodegrade for hundreds of years. This allows it plenty of time to wreak havoc in ecosystems. For instance, sea turtles mistake plastic bags for jellyfish, and eat them. The plastic blocks their digestive tracts, causing painful deaths. Have you ever heard of the Pacific Garbage Patch? It's a plastic continent, at least twice the size of Texas, floating in the Pacific. It's composed of waste, most of which originated on land. Recycling plastic bags is essential, but even this uses considerable energy, which pollutes the air. Banning plastic bags would alleviate these problems. However, plastic must be replaced with reusable bags, not necessarily paper. The problem is, people are accustomed to cheap, convenient lifestyles, and many are unwilling to switch to reusable bags. But I use cloth bags at Target and Winn-Dixie, and I find them to be much more convenient than plastic or paper, because they are sturdier and hold more stuff. So the only real disadvantage that I can think of is that the plastic bag industry would suffer, which is not good is this economic climate. Others might disagree, but IMHO the environment is more important than big business. A final note: As Plastic bags do not account for all of the plastic waste we produce. Most items in stores are over-packaged and use excessive plastic, because the packaging is used for advertisement, not just to protect the product. In order to solve the problems caused by plastic waste, we must recycle, decrease and/or eliminate all plastic, not just bags.
Q:How to mold hollow plastic?
No idea how to do that at home, plastic bottles, figurines, and such that are molded are done thru a blow molding process which requires huge machinery and such. Prolly better off doing it out of clay or even a paper mache type of deal then coating it to make it waterproof.
Q:Waste plastics recycling benefits?
A major measure to reduce solid waste in urban areas, rural areas, farmland and water, and to prevent environmental pollution. It is also a means of utilizing renewable resources.
Q:Help! Burnt plastic on burner!?
The good news is you didn't have a fire. The bad news is you are going to have a really tough time removing the plastic residue. It depends on the type of plastic, but assuming it is the usual type of softer plastic (such as Tupperware, etc.), these things are heck to remove. You may have to try to heat the burner again, until the plastic just begins to soften, and then use a putty knife to scrape the residue off. Then, when the element is cooler, use a wire brush such as you use on a barbecue grille to scrape the rest off. (DON'T breathe the fumes as the plastic melts ! ) You might also try to write or telephone the company which manufactured the plastic cover, and tell them (don't be embarrassed--you are not the first person to do this. Maybe they can suggest a chemical that can soften the plastic and make it easier to remove. But remember that many chemicals, such as acetone, are very flammible, so you don't want to use it on a hot or warm burner element. That's about the best I can suggest. Good luck.
