the main use of micro silicon powder-pg电玩城

  the main chemical composition of microsilica is sio2, the content can reach 85-95%, and its elements include fe2o3, al2o3, cao, k2o, na2o, mgo, c and so on. the microsilica has an average particle diameter of 0.1-0.15 μm, which is a few percent of the average particle size of the cement. it has a specific surface area of 15-27 m2/g and is extremely surface active.

additives for refractory materials using microsilica for refractory materials:

  every year, japan imports a large amount of microsilica from china for the refractory industry. according to the research report of the kobe steel refractory research institute in japan, high-quality microsilica is mainly used as high-performance refractory castables, prefabricated parts, steel-clad materials, permeable bricks, self-flowing refractory castables and dry and wet spray materials. according to the research report submitted by the osaka institute of industrial technology, in the field of high-temperature ceramics, such as: oxide-bonded silicon carbide products, high-temperature calcium silicate lightweight insulation materials, electromagnetic kiln with corundum mullite push plates, high temperature wear resistance materials and products, corundum and ceramic products, sailong combined products, etc., the use of microsilica has high fluidity, low water storage capacity, high density and high strength.

  high-strength blending agent for microsilica concrete industry:

  the application of microsilica for concrete as a blending agent in the concrete industry is one of the earliest research, the most fruitful and the most widely used in the comprehensive utilization of foreign microsilica. since the microsilica has physical and chemical characteristics such as fine particles, large specific surface area, high purity of sio2, and strong volcanic ash activity, the addition of micro-silica powder as a blending agent improves the performance of various aspects of concrete. such as significantly improving the adhesion and cohesiveness of plastic concrete, greatly reducing the amount of springback, increasing the thickness of shotcrete once formed, shortening the construction period and saving engineering cost.

   other uses of high-quality microsilica are mainly reflected in the following six aspects:

1. as a pellet binder: microsilica powder has a large specific surface area and strong adsorption, and has achieved remarkable effects as a binder for pellets in foreign countries.

2, as an anti-caking agent: instead of mica or diatomaceous earth as a raw material to prevent the agglomeration of fertilizer particles.

3. rubber industry: after adding a certain amount of microsilica to rubber, its elongation, shrinkage, tear resistance and anti-aging degree are greatly improved. this rubber also has good dielectric properties and low water absorption capacity.

4, in the insulation materials, waterproof materials, paints, coatings, printing industry, etc. have been applied.

5, water glass industry: micro silicon powder can replace quartz ore, produce a water glass with a modulus of 4.

6. in the oilfield as a cementing use: jilin oilfield, liaohe oilfield, karamay oilfield, etc., all use microsilica and achieve good use effect.
