Q:Water glass, ceramics, ordinary cement, quartz glass, what are these chemicals?

The main component of these substances, ceramics, cement, and quartz, is SiO2. In addition, SiO2 is also used to make optical fibers.Elemental silicon is used to make solar panels, chips and other materials

Q:Can the toughened glass be cracked by the sun?

Characteristic safetyWhen the glass is destroyed by the external force, the pieces will become honeycomb like obtuse broken small particles, not easy to cause serious harm to human body.

Q:What material does PCB have?

The main material of printed circuit board (PCB) is copper clad laminate, and copper clad laminate is made up of base plate, copper foil and adhesive. The base plate is an insulating plywood made of macromolecule synthetic resin and reinforcing material;

Q:The glass door in the shower room is too heavy. What material can be substituted, which is as transparent as glass but lighter than glass?

Glass material mainly has three parts: basic material, flux and colorant, and also includes decoloring agent, clarifying agent and corrosion inhibitor* basic materials for glass makingSilica is the main raw material made of silica on the earth reserves is great. Silica is the main raw material for the main raw material is made of glass stones. The silicon content of different rocks are different. In our life of these materials is the most common.

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

This is because of containing nickel sulfide crystal glass raw material, manufacturing technology in the world is any existing can not be completely avoided, only reduce the exploding probability through control of the purity of raw materials and processing technology to a.It blew the concept of rate, the national standard of our country only glass project on the wall, I do not know whether the other foreign industry to use the toughened glass also has detailed provisions.

Q:Which brand of thermos cup is safe, double glass is not really glass, there is no other add, affect health?

Insulation cup is generally made of ceramic or stainless steel containers with vacuum layer made of water, the top cover, seal, vacuum insulation layer can make the liquid inside the slow cooling, in order to achieve the purpose of preservation.

Q:What is the ratio of raw materials for glass mildew proof powder?

Coconut shell plant essence ("compendium") from endocarp for palm plants in coconut. Coconut palm in plant form. The chemical composition of coconut shell containing 0.61% ash, 36.51% lignin, cellulose 53.06%, pentosan (29.27% total). Cellulose containing 20.54% pentosan, principal components in the ash and koh.

Q:Could you tell me that three yuan ethylene propylene (EPDM) rubber can resist ethylene glycol?

Three yuan ethylene propylene is ethylene, propylene and non conjugated diene three copolymer. Diene has a special structure, only one of the two keys to copolymerization, unsaturated double bond, mainly as the chain. Another unsaturated polymer will not become the main chain and will only become side chains. The main polymer chain of three yuan ethylene propylene is completely saturated. This property allows three yuan ethylene propylene to resist heat, light, oxygen, especially ozone. Three yuan propylene is essentially non-polar, resistant to polar solutions and chemicals, low water absorption, and good insulation properties.

Q:How do you pack something into (Qian Jin) plexiglass?

I have been in touch with gel products for a while, and I feel that if the discharge circuit is too soft, it will be easy to damage the circuit board. As far as plexiglass is concerned, I have to ask my fellow inorganic students how they did it.

Q:What materials do we need to make glass septic tanks?

9., the product covers only 60 ~ 80% of the brick and concrete septic tank, which saves land and improves the flexibility of site selection.10., the comprehensive cost is low, and the overall cost is more economical compared with the brick and concrete septic tank.
