Product Description:

Covering Material:

 

Float glass. (Single-layer or double-layer)

This glass is molded in the tin tank with the gas (H2, N2) and has high smoothness. And excellent light transmittance rate is more than 90%. In addition, it has better resistance and UV compartment capacity. And low thermal expansion and contraction coefficient. All the features decide that this kind of glass could last more than 20 years with good appearance.

 

Toughened (Tempered) Glass. (Single-layer )

Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. when toughened glass broken,  it will crumble into small granular chunks instead of splintering into jagged shards. However, the light transmitance is nearly the same as normal float glass.  

 

Scattering Glass( Single-layer)

Scatering Glass is a kind of newly designed glass which is specially treated on the surface and structure and it can divide the direct light into smaller beams of light with different directions. It increases the light transmitance and uniformity in the greenhouse and decrease the shadow area of greenhouse structure effectively.  The light transmitance of scattering glass is more than 97.5% and it can increase more than 15% production.

Q:Questions about plastic bottles ?
They make other things out of plastics and they not use it again as it was before. True, I believe that recycled plastics costs a lot than making new ones because of the many processes that will be made .
Q:What is rapid sorting?
Paper plastic composite film, paper plastic composite film on recycling before the first paper separation, this is a method of paper plastic composite separation, separation equipment for electric heating with a chrome plated hollow barrel, the barrel is equipped with a hollow cylinder with a blade, the cylinder and the hollow cylinder to rotate in the opposite direction, a mixture of paper and plastic after the break of the adding barrel in the barrel by heating a mixture of the plastic melt in the barrel at the lower part of the discharge, the air in the hollow cylinder exhaust.
Q:should plastic be banned?
no, and if your going to go Oh it's bad for the environment it really isn't. Sure the stuff that gets thrown away will be around forever, but a larger majority gets recycled. And we reduce carbon levels in our atmosphere by making plastic, since it is made mostly of carbon.
Q:method to make use of mixed plastic?
The reason the different types of plastic are segregated before recycling is that when melted together, they don't blend into a homogeneous mixture. In fact, after cooling back down, they will separate back into even - more - difficult - to - separate mixed plastic solids. All I can suggest is, since these materials are derived from petroleum, they can be burned for a pretty good amount of energy. The lone exceptions are the PVCs and similar plastics, which give off HCl gas when burned.
Q:Science help?! Polymers and plastic bags...?
When you stretch plastic, it heats up. This heat causes a change in the molecular structure of the plastic allowing it to stretch. The stronger a bit of plastic is, the more tightly bound the molecules are. Different plastics have different melting points as well. A few types of plastic that you might deal with every day are HDPE (plastic bags and milk jugs), Polycarbonate (clear plastic drink cups) and PET-E (soda bottles) Each of these plastics start to soften at about 300F (degrees Farenheit) HDPE becomes molten (liquid like and able to be formed) at about 350F Polycarbonate at about 400F PET-E at about 375F If I remember correctly. Anyways, I hope the explanation of melting points and heat help to explain why some plastics are stronger. In some cases the thickness of the material matters as well.
Q:What are plastics?
As part of organic (Carbon Based) chemistry, they are polymers comprised of Carbon, Hydogren and Oxygen.
Q:plastic bumper bars ?
a little more information would have been usefull a plastic bull bar is not really usefull as it will crack and shatter upon inpact and as for a plastic bumper bar it,s only handy as it bends and flexes. i don,t really know where you want to go with this so i volunteer that i have a massive allround 4 post heavy duty aluminium bull bar which is also useless at high speed collisions as it bends into the front tyres causing them to deflate where upon i would lose control of the steering and a plastic one would not do this but it makes no sense to fit them either. the difference between a bullbar and a bumperbar is that the bullbar should surround the head lights from left to right where upon a bumper bar is just that.
Q:Fishing Plastics Help?
I am in no way affiliated to them, I just thought it was odd that I found this the day or so before you asked this question. I am going to try it before I start melting any of my stuff down. Best of luck to you. JB
Q:How does plastic breakdown?
Biodegrades like compost (but after like 20 years)
Q:Is smoking weed out of a plastic bong really unhealthy?
tricky step. check out at yahoo. that could actually help!
