The 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......
2019-06-27Electronic packaging material Organic electroluminescent device (OELD) is a new type of flat display device newly developed. It has low on-drive and low-drive voltage, and can be driven by DC voltage......
2019-06-27Hydrophilic fumed silica Hydrophilic fumed silica is produced by hydrolysis of volatile chlorosilanes in an oxyhydrogen flame. From a chemical point of view, these loose white powders are composed......
2019-06-27Fumed silica, the product is a synthetic amorphous white fluid powder with various specific surface area and volumetric particle size distribution. This product is a white, loose, amorphous, non-toxic......
2019-06-27The silica has decomposition or adsorption effect on the accelerator, and the addition of the surfactant can reduce the decomposition and adsorption of the silica to the accelerator. The reinfor......
