What is Quartz powder?
Quartz powder is divided into different grades and specifications. The Quartz powder is gray; the particles are spherical and excellent; the smallest particle is less than 0.01UM, the average particle size is 0.1-0.3UM, and it is easy to combine into a loose lump at room temperature. With high gelation ability and adsorption capacity, Quartz powder is made of natural quartz (SiO2) or fused quartz (natural quartz after high temperature melting, cooling amorphous SiO2) by crushing, ball grinding (or vibration, air grinding), flotation, pickling purification, high purity water treatment and other processes into the powder. Quartz powder has good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, chemical stability, high hardness, and other excellent properties.
Properties of Quartz powder
Quartz powder is a neutral inorganic filler, does not contain crystallizing water, does not participate in the curing reaction, does not affect the reaction mechanism, is a stable filler, the surface is neutral, when the adsorption water content is minimal, from the hydrogen bond surface and resin, good flexibility for all kinds of polish, good infiltration, excellent adsorption characteristics, easy to mix, no clumping phenomenon. It can reduce the exothermic peak temperature of epoxy resin curing reaction and reduce the coefficient of thermal expansion and shrinkage of fixing substance to eliminate the internal stress and prevent cracking. It can increase the thermal conductivity, change the adhesive property and improve the flame retardant. Because of the fine particle size of Quartz powder, it can effectively reduce and eliminate precipitation and stratification. Silica powder is pure and stable, so the cured material has excellent insulation and arc resistance. After adding Quartz powder, the amount of acetone can be reduced, and the cost of products can be reduced. There are no fine black impurities, and it is very suitable for high Tg and thin laminate process requirements.
Analysis of two kinds of products, microQuartz powder and microQuartz powder
Most domestic manufacturers of Quartz powder and micro-Quartz powder need clarification on the concept of the two only from the literal meaning of understanding the two as a product. There is a big difference between micro-Quartz powder and micro-Quartz powder. It is precisely because of the unclear concept of the two; the market of micro-Quartz powder and micro-Quartz powder in China needs clarification, leading to many trade negotiations. The market price of micro-Quartz powder is far lower than that of the international market. It has negatively impacted the international reputation of the need for micro-Quartz powder and micro-Quartz powder in China. With the deepening understanding of Quartz powder and Quartz powder abroad, Quartz powder and micro-Quartz powder have been widely used. Their commercial advantages and vast market space have gradually been highlighted. To distinguish the relationship between the two, clarify the chaotic state of the market, and reduce the loss of enterprises, the author will make a specific analysis of these two products from the appearance, performance, production process, use, indicators, market status, and other aspects.
Price of silica powder
Silica powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Silica powder. A large amount of large amount will be lower. The Price of silica powder is on our company's official website.
