Changqing New Material

China presided over the development of fumed silica ISO international standards successfully released

Nano-new materials are a strategic emerging industry that countries all over the world are competing to develop, especially scientific and technological powers will develop nano-new materials as a national strategy. Fumed silica (commonly known as fumed silica) is a white fluffy high-purity nano-inorganic non-metallic oxide. It is a nano-material prepared by the gas phase method on a large scale. It is also a nano-powder material that has been widely used so far, driving the development of hundreds of billions of downstream markets.

Silica giant Cabot announced a 15% price increase for fumed silica and silica sol.

The world's silica giant Cabot recently issued a price increase notice, announcing that from May 30, it will increase the price of fumed silica and silica sol worldwide by up to 15%.

Science Online: Why does water freeze while silica forms glass?

Everyone knows that water freezes at zero degrees Celsius, but the "cousin" silica of water shows unstable behavior during the cooling process. When liquid silicon is cooled, its atoms cannot be arranged into orderly crystals. The resulting solidified substance-a mechanical solid, but a microscopic liquid-is a glass.

Paint the old driver to take you to understand the mystery of paint filler! Get in the car! (II)

In the last article, Xiao Bian explained some fillers for building coatings such as calcium carbonate and talcum powder, which were recognized and responded by everyone. At the request of everyone, Xiao Bian continued to show you what other fillers are used for building coatings. (want to know more about building coatings with filler friends can look at the small part of the previous article oh!)

What is the main silicone products, do you know?

Before the silicone product is formed, different components in the raw material are the core technology of the product. In the silicone rubber raw material, different chemical agents can be divided into different chemical agents to achieve the expected effect. For the silicone rubber raw material, * * * is like candle wick and wax oil. In addition, the technical blending of silica can also change various properties and effects of the product, so you don't know about silica, you can learn more here!

Comprehensive utilization of fumed silica and asbestos tailings

Fumed silica, also known as fumed silica, is a kind of fine nano-scale amorphous silica obtained by high temperature hydrolysis of halosilane in hydrogen-oxygen flame. It has small particle size, uniform particle size distribution, large specific surface area and high surface activity. Fumed silica is widely used in polymer composite materials, silicone rubber, coatings, electronic packaging materials, colloidal batteries, ceramics, plastics, glass fiber reinforced plastic, sealants, paper, food, cosmetics, gel coat resin, chemical mechanical polishing and other industries, can play a reinforcing, thickening, thixotropic, extinction and other roles.
