The substance used as the surface treatment agent can in principle interact with the hydroxyl group on the surface of the silica, and there are the following. 1) Alcohol 2) Chlorosilane 3) Alkoxysila......
2019-06-28The use of nano-silica is very broad, generally adding weight of 0.5-2%, and individual product systems can reach more than 10%. The key to product performance is: fully dispersed into the system. Whe......
2019-06-28Nano-silicon dioxide is an inorganic chemical material, commonly known as white carbon black. Because it is ultra-fine nano-scale, the size range is from 1 to 100nm, so it has many unique properties, ......
2019-06-28Silica is superior to other white fillers in reinforcing other rubbers, second only to carbon black. Compared silica filled vulcanizates, silica/rubber composites have the advantages of good insulatio......
2019-06-28The amount of hydroxyl groups on the surface of silica also has a large effect on the performance of silica. The amount of hydroxyl groups is too small, the agglomerates formed are less rigid, and the......
2019-06-28Fumed silica is an important inorganic functional material with a wide range of applications. It is mainly used as a reinforcing agent in silicone rubber and special rubber, and its reinforcing effect......
2019-06-28Whether it has been treated or not, silica has good thixotropy in many systems. Of course, nanoscale is also required to have a significant effect, and micron-sized silicon micropowder is much worse. ......
2019-06-28There are three kinds of silicic hydroxyl groups on the surface of silica. This is not the result of my experiment. The result of human research is that the structure (hydrogen bond) should be the kin......
2019-06-28The foamed silicone rubber is based on a condensation-type hydroxyl-terminated silicon raw rubber, the hydroxyl-containing hydrogen-containing silicone oil is a foaming agent, and the vinyl platinum c......
2019-06-27The addition room temperature vulcanized silicone rubber is a colorless or slightly yellow transparent oily liquid, which becomes a soft and transparent silicone gel after vulcanization. The gel maint......
2019-06-27Due to its excellent properties, silicones have a wide range of applications. It is not only used as a special material for aviation, cutting-edge technology, and military technology departments, but ......
2019-06-27Cosmetics For cosmetics, it is required to have strong UV shielding ability. It is best to protect against UVB damage to the human body and to protect against UVA. In essence, the ultraviolet shieldi......
2019-06-27FRP products Although the FRP products have the advantages of light weight, high strength and corrosion resistance, they have low hardness and poor wear resistance. The relevant experts added the fum......
2019-06-27Yan (dye) Although organic pigments (dyed) have bright colors and strong tinting strength, they are generally inferior to inorganic pigments in light resistance, heat resistance, solvent resistance a......
2019-06-27Plastic The use of fumed silica is light-transmissive and has a small particle size, which makes the plastic more compact. After adding fumed silica to the polystyrene plastic film, it not only impro......
