white microsilica【价格 厂家 供应】-pg电玩城

gansu, xinyuan microsilica co., ltd. according to different application fields, the launch of different grades of microsilica, recently launched the white microsilica, successfully applied in compound fertilizers, pesticides (as adsorbent, or producing silicon fertilizer), paint, paint (as thickener, flooding agent), rubber (as a reinforcing agent), plastic (as filling agent), special ceramics, alternative white carbon black, reduce the cost. the main indexes are as follows:

1) whiteness: greater than or equal to 80%

2) sio2: > 92%

3) screening remainder of m: less than 4%

4) volcanic ash activity: greater than or equal to 105

due to the low production of white microsilica, our company has limited supply of end users at present.

microsilica (or silica fume) is amorphous, powdered sio2 collected by specially designed dust collector after the oxidization of silicon steam emitted by flue during the smelting of ferro-silicon alloy or industrial silicon. with an average particle size of 0.15~0.20 crystalline m and a specific surface area of 15,000 ~20000m 2 /kg, the microsilica has a strong surface activity.

the main component of microsilica is amorphous silica, and the rising furnace gas also contains impurities, such as free c, fe2o3, cao, k2o, na2o and so on. the color of microsilica changes from white, grey to grey and deep grey as c and fe2o3 content increases.

the micromicrosilica directly after dust collection is called raw ash, whose bulk density is 150~300kg/m3. for the convenience of transportation and engineering application, the original ash can also be encrypted.
