Q:What are the paper made of? What is the glass made of? What is the plastic made of?

Plastic polymer polymer synthesis {(polymer)}, also known as polymer or giant molecule (macromolecules), is generally known as plastic resin (plastics) or (resin), free to change form style. It is a kind of material which is synthesized by condensation or condensation of monomer material. It is composed of synthetic resin and filler, plasticizer, stabilizer, lubricant, pigment and so on. Its main component is synthetic resin.

Q:What are the aluminum films used in glass processing enterprises?

(1) the enterprise purchase and acceptance of storage materials, the planned cost or actual cost, debit "raw material" subjects, according to the actual cost of credit "material procurement" or "goods in transit" subjects, according to the difference between the planned cost and actual cost, debit or credit "material cost difference" course.

Q:How to choose floor tiles?

Vitreous tile belongs to all ceramic product. Its abrasion resistance and flexural strength are very high, the water absorption rate (tile water absorption rate is less than 1 per thousand). Before the tiles mainly used for flooring, tiles, as a wall material is mainly used for high-grade Gaestgiveriet Hotel, office space, but now, with the living standard and the improvement of consumption level, the home use tiles for the kitchen wall materials are more and more family.

Q:Samsung LCD panel information

This screen is indeed the original Samsung screen, Samsung Electronics, Tianjin Corporation assembly production.TSEC is the sign of Tianjin's samsung. So he wrote the MADE IN CHINA (TSEC) behind him

Q:Not man-made destruction, why toughened glass suddenly broken?

There are a variety of predisposing factors 2. tempered glass explodeFor example, A. before the installation of glass is accidentally damaged, like chipping, knocked the feet, because the glass is tempered around the weak area, its strength even weaker than the non tempered glass, but this part of the damage are not likely to cause the glass immediately burst, but changed the internal stress of glass. When the upper wall is used, the internal stress changes gradually, which breaks the glass.B. such as differences in temperature after installation. As you say, temperature, weather, and so on, will make the internal pressure of the glass partial uneven, thus causing burst.Is there a correct size for the C. installation?. If the installation is too tight, the specifications are not appropriate, it will cause stress changes inside the glass, causing a burst.D. the rest is external force, including impact, extrusion and so on. It's not just human impact, or other things, or even wind in nature. If the glass does not fall on the ground, there will be the point of impact (if it is obvious, there will be explosive, Hu Dieban) these can be invoked, but if in the proceedings can only be said to be a possibility, because you have no evidence to prove that. In the domestic situation, the glass manufacturers generally compensate for the glass trouble.

Q:Aluminum alloy window material is good, how to assemble?

Glass block: chloroprene rubber, polyethylene and nylon lead block. It is two kinds: the first is to glass and Aluminum Alloy slot and slot bottom metal parts separated by a gap, to ensure control of glass and metal frame relative size effect; second is to prevent the glass due to stretching and metal parts of the collision.

Q:Does fiberglass contain formaldehyde? I'm a hair salon. Buy a glass fiber reinforced plastic shampoo bed, there is always a pungent smell of the body, there is no harm to it, including formaldehyde free

Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. The main raw materials of glass fiber reinforced plastics are resin, curing agent and glass fiber. Glass fiber is not toxic, but contact the skin will be itching. And resin and curing agent have certain harm to human body, especially curing agent, if it is the curing agent of aromatic amine, that is relatively harmful to human body.

Q:Why are most of the chemical instruments made from glass?

Of course, the glass is colorless and transparent is also very important, the front of some people said that the glass is cheap, I would like to deny, in fact, this glass is not often in general glass, high temperature, the cost is much higher than that

Q:What are the raw materials of glass fiber reinforced plastic?

It is a kind of composite material made of glass fiber and its products (glass cloth, band, felt, yarn, etc.) as reinforcing material and synthetic resin as base material.

Q:What kind of glass material is used in the aquarium?

Toughened glassToughened glass is a kind of high strength safety glass which is heated by glass to softening point and then cooled rapidly. Under the same thickness, the flexural strength of tempered glass is 4-5 times higher than that of ordinary glass, and the impact strength is 5 times higher than that of ordinary glass. Toughened glass has a strong thermal stability and can withstand severe temperature changes without damaging it. The most important feature of tempered glass is safety. This kind of glass is broken into similar honeycomb particles, so it can avoid the harm to human body. Note: after tempering, the glass can not be cut, drilled, slotted and so on. Because glass is broken into honeycomb like particles that are completely irreparable, it is not recommended for use on aquariums!
