Brief introduction:
Microsilica fume (scientific name "silica fume, " Microsilica or Silica Fume), in the smelting of ferrosilicon and industrial silicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2). Micro-silica fume average 0.1-0.15 μ m in diameter, the size of several cement average 1.0%. Surface area for the 15-27 m 2 / g, with strong surface activity. Features Characteristics
1). Appearance is as grey&white off.
2). High electrical resistivity
3). Low Permeability
4). Superior resistance to chemical attack from chlorides, acids and sulfates
5). Low chloride ion diffusion
6). High reactive Pozzolan
7). High temperature strength
8). Improved stability ingeothermal environment
Quanzhou Winitoor Industry Co., Ltd was established in 2004 in Fujian Province of China. Our company specializes in the manufacturing and exporting silica fume.
We establish long-term and stable relationship with several large-scale ferrosilicon and silicon metal factories in Fujian, Sichan, Yunnan and Lanzhou etc. To control the raw materials quality and ensure the annual output at least 50, 000MT.
Winitoor has build excellent business relationship with customers from all over the world, such as Japan, Korea, Australia, Canada and Middle East etc. Especially the Middle East market, we export thousand of silica fume to gulf countries monthly and enjoy high reputation.
We built our own silica fume processing plants in the major areas of Chinese ferro-silicon and silica metal factories.
Our material is collected by furnace during the metal silica or ferro-silicon produce, direct package from equipment, guaranteed 100% pure material.
