Q:What are the raw materials made of glass and plastics?

Low density polyethylene, referred to as LDPE is the amount of varieties of plastic packaging and printing industry in most countries. The proportion is 0.92 ~ 0.93, can float in water. Low crystallinity (60%), under the pressure of 1000 ~ 3000kg/C square meters of bulk polymerization of high pressure polyethylene. At 23 degrees Celsius, the density of rolling around 0.92. The molding is poor, for blow molding processing into tubular film. It is suitable for food packaging, packaging, cosmetics packaging fiber products.

Q:What are the anticorrosive materials for glass fiber reinforced plastic?

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

Double glass also called light industrial glass, raw materials for high boron silicon has a high heat resistance, the main production of glass teapot, coffee cup, cup, cup of hot water, there are many domestic manufacturers.

Q:The main reasons for failure of air glass are outlined

The requirements of the desiccant performance must have low initial adsorption capacity, easy production and operation, while the remaining strong adsorption capacity, ensure the sealing hollow glass has more adsorption capacity and only adsorption, water molecules with wear strength, usually choose 3A molecular sieve as a special adsorption of hollow glass as for the special agent, contain volatile sealant, special ability requirements of desiccant adsorption of organic molecules, the general choice of 13X molecular sieve, molecular adsorption as water and adsorption of organic compounds by sieve. The desiccant absorption capacity of the water vapor as the desiccant temperature varies, different desiccant absorbs water vapor in a given number of different temperature conditions, depending on the hollow glass cavity obtained rate of water vapor, water vapor growth rate is a function of several factors

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 is the raw material of glass fiber reinforced plastics and what is the matching ratio?

Q:What material can not be sprayed on the glass?

If you want to spray characters on the glass, it is impossible to follow the glass unless it is frosted. If you really want to spray words on the glass, you can go directly to the print shop, do the word, and then stick it up.

Q:The use of quartz sand

Quartz sand is quartz quartz stone crushing processed. Rock (quartz), also known as silica, is a hard, abrasion resistant and chemically stable silicate mineral. In nature, quartz sandstone, quartzite and quartz quartz exist. Quartz sandstone is a consolidated clastic rock with a quartz content of more than 95%,
