fine microsilica【价格 厂家 供应】-pg电玩城

application of high quality microsilica in refractories:

microsilica, as a new raw material, is widely used in refractory industry. it plays an important role in the improvement of amorphous refractory. characterized by:

1. there are many pores in traditional refractory materials, and microsilica is filled into the pores, which improves the volume density and reduces the porosity, and the strength can be significantly enhanced;

2. the microsilica has strong activity. colloidal particles can be formed in water.

3. it is easy to form -- si-oh group in water, with strong hydrophilicity and activity, which can enhance the agglomeration of refractory materials, greatly improve the high-temperature performance and extend the service life of refractory products.

other uses of high quality microsilica:

1. cement industry: after adding silica powder into cement, the performance is improved, the quality and the label are greatly improved;

2. rubber industry: when a certain amount of silica powder is added to the rubber, its elongation and shrinkage, tear resistance and aging resistance are greatly improved.

3. as anti-agglomeration agent: replace mica or diatomaceous earth as raw material to prevent agglomeration of fertilizer particles;

4. as pelletizing adhesive: the microsilica powder has a large surface area and strong adsorption ability, and it has achieved remarkable effect in foreign pelletizing binders;

5. water glass industry: it can replace quartz mine and produce glass with module 4;

6. it is used as well cementing in oil fields: jilin oil field, liaohe oil field, karamay oil field, etc., all use a large amount of silica powder and achieve good results;

7. it has been applied in insulating materials, waterproof materials, paints, coatings and printing industries.

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!
