Source Lei | Silicon Micropowder Series-Spherical Silicon Micropowder

 

spherical silica powder

 

 

Performance:Source Lei brand silicon powder is a white amorphous powder, light weight.

 

 

Features:Silicon powder refractoriness> 1600 ℃. Bulk density: 200~250kg/m3; more than 80% of the silicon powder has a fineness of less than 1 micron, an average particle size of 0.1~0.3 microns, and a specific surface area of 20~28 m/g. Its fineness and specific surface area are about 80 to 100 times that of cement and 50 to 70 times that of fly ash.

 

 

Scope of application:Paint coating with silicon powder, epoxy floor with silicon powder, rubber with silicon powder, sealant with silicon powder,. Silicon micropowder for electronic and electrical grade plastic sealing materials, silicon micropowder for precision ceramics.

 

1、Silica powder for paint coatingNumber of meshes: 400-2500 meshes

SiO2:>99.5 whiteness: between 70-94 degrees hardness: 7 (Mohs hardness)

Oil absorption, low mixing viscosity, good dispersion and fluidity, small angle of repose formed by accumulation and friction resistance.

 

2、Silicon powder for epoxy floorNumber of meshes: 400-1250 meshes

SiO2:>99% whiteness: between 70-94 degrees hardness: 7 (Mohs hardness)

Low viscosity, good fluidity, good accumulation, easy compaction, easy to combine with epoxy resin. Compared with traditional silicon powder, it can save the amount of epoxy resin.

 

3、Microsilica powder for rubberNumber of meshes: 1250-5000 meshes

SiO2:>99.5 whiteness:>70-94 degrees hardness: 7 (Mohs hardness)

Wear-resistant rubber products include rubber plates, pipes, belts and rollers. It requires the compound to have good permeability and strong adhesion. The test results show that the compound filled with silicon micropowder fully embodies the unique properties of the compound such as thin rubber, good permeability, good dispersion and strong adhesion, which is conducive to the wiping of the compound on the canvas and enhances the adhesive strength between the film and the canvas, the tear strength, permanent deformation and other mechanical properties of the product.

 

4、Silica powder for sealantNumber of meshes: 1250 meshes

SiO2:>99.5 whiteness:>80-94 degrees hardness: 7 (Mohs hardness)

The water content of the treated silica powder is less than 0.1%, which can improve the adhesive strength, yield value and shear dilution index of colloid when used in sealant. With thickening, reinforcing effect, anti-tearing, anti-aging effect.

 

5、Silicon micropowder for electronic and electrical grade plastic sealing materialsNumber of meshes: 600-5000 meshes

SiO2:>99.5 whiteness:>90 degrees hardness: 7 (Mohs hardness)

Quasi-spherical silicon powder used in epoxy resin insulation packaging materials, can greatly increase the filling amount, reduce the viscosity of the mixed material system, improve the processing performance, improve the permeability of the mixture, reduce the expansion coefficient of the cured material and the shrinkage rate of the curing process, reduce the thermal expansion difference.

 

6、Silicon powder for precision ceramicsNumber of meshes: 5000 meshes

SiO2:>99.7 whiteness:>92 degrees hardness: 7 (Mohs hardness)
