picture of xysil fumed silicaOur hydrophilic fumed silica is white,innoxious, insipid, amorphous fine chemical powder. XYSIL fumed silica is with features such as small partical size, large BET surface area, high surface activity and high purity. The original particle size can be 7-40 nm according to system setting, and the BET surface area is 70 – 40 m2/g. Because of Nanometer Effect, XYSIL fumed silica performe excellent nature of reinforcing, thickening, thixotropy, insulation, matting, resist sagging, it is widely used in High Temperature Vulcanization(HTV) Rubber and Room Temperature Vulcanization(RTV) Rubber, coating, painting…

Xunyu Chemical introduces the Gas-Phase manufacturing technique, which includes seven courses: Pretreatment of raw material, Aggregate, Gas-Soids Separation, Deacidify, Packing, Waste gas treatment.

By hydrolyzing SiCl4 , a byproduct in the procedure in production of polysilicon, in oxyhydrogen flame at high temperature, we get the Primary particles, a particle of 7-40nm. The Primary particles forms agglomerate measured by micron, after being accumulated and collided, the agglomerate and the waste gas produced in the production of Primary particles at high temperature, go into the high efficiency separator, which is called the gas-solid separation. SiO2 from the bottom of the High Efficiency Separator goes into the Deacidiy Tower to deacidify, after that, the products…
