In the current national standards for micro-silica fume, various indicators of silica fume of different specifications have been adjusted, especially various impurities have been strictly controlled, and the specific surface area and the fineness of different specifications have been unified, thereby the performance of the standard micro silicon powder is greatly improved, and its application range becomes wider.
1. According to different SiO2 content, the use of silica fume is different: SF88 is mainly used for the admixture of ordinary concrete and the use of refractory and wear-resistant materials with lower requirements; SF90 is mainly used in general refractory materials; SF93 is mainly used for high-strength concrete that requires fluidity and refractory insulation materials with higher requirements; SF96 is mainly used for high-strength and ultra-high-strength concrete admixture.
2. In addition to the above uses, micro-silica powder also plays an important role in the material industry, such as making ceramic kiln furniture, making corundum mullite push plates for electric porcelain kilns, etc., and can also participate in the production of silicate brick raw materials, production water. At the same time, it can also be used as filling and reinforcing material in polymer materials such as rubber, resin, paint, unsaturated polyester, etc., and can also be used as high-quality filler, thickener and matting agent for coatings.
