the price of microsilica is also related to the transportation distance. transportation costs account for a large share of the total cost of the microsilica. for example, customers close to gansu lixinyuan microsilica manufacturers use microsilica prices are very cheap. unencrypted microsilica is more expensive because of its large size and high transportation costs. the main advantage of crypto-microsilica price is to save transportation cost.
description of microsilica products
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 micro 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 microsilica 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.
microsilica is a by-product of silicon iron or industrial silicon industry. according to the size of silicon furnace and different silicon raw materials, the company strict selection of materials, strict grade processing. products manufactured by the company are subject to inspection by any third party testing organization. please feel free to buy!
