Product introduction：White powder，very light weight.

Introduction：Silicon micro-powder fire resistance greater than 1600 °C, bulk density: 200 ~ 250 kg/m3. The fineness of silica fume less than 1 micron accounts for more than 80%, the average particle size is 0.1 ~ 0.3 micron, the specific surface area is :20 ~ 28m/g. , its fineness and specific surface area are about 80 ~ 100 times of cement, , 50 ~ 70 times of fly ash

Application：The silica powder can be divided into: silica powder for paint coating, silica powder for epoxy floor, silica powder for rubber, silica powder for sealant, silica powder for electronic and electrician grade plastic sealing materials, and silica powder for precision ceramics.

1. Silicon powder for paint coating

Main specifications:600 mesh--2500 mesh     　SiO2:>99.5%

Whiteness: 70-94 degrees.         Hardness: 7(Mohs’scale of hardnes)

Oil absorption, low mixing viscosity, good dispersibility and fluidity, small Angle of rest formed by accumulation, friction resistance

2. Silicon powder for epoxy floor

Main specifications:600 mesh--1250 mesh     　SiO2:>99.5%

Whiteness: 70-94 degrees.   Hardness: 7(Mohs’scale of hardnes)

Low viscosity, good fluidity, good accumulation, easy to compaction, easy to combine with epoxy resin. Compared with traditional silicon powder, epoxy resin dosage can be saved.

3..Silicone powder for rubber

Main specifications:1250 mesh--5000 mesh     　SiO2:>99.5%

Whiteness: 70-94 degrees.   Hardness: 7(Mohs’scale of hardnes)

Wear-resisting rubber products including rubber sheet, tube, belt, roller, it requires that the mixed gel has good permeability and strong cohesiveness, experimental results show that populate the silicon powder mixing rubber embodies the rubber thin, good permeability, good dispersibility, unique properties, such as strong bonding is advantageous to the mixing glue on the brush paint on the canvas and strengthened the film and the adhesive strength between canvas and break strength of the products, permanent deformation and other mechanical properties

4.Silicone powder for sealant

Main specifications:1250 mesh-      　SiO2:>99.5%

Whiteness: 80-94 degrees.   Hardness: 7(Mohs’scale of hardnes)

The water content of silicon powder after treatment is less than 0.1%, which can improve the adhesive strength, yield value and shear force dilution index of the colloid. It has the function of thickening, strengthening, tearing resistance and aging resistance.

5. Silicon powder for electronic grade and electrical grade plastic sealing materials

Main specifications: 5000 mesh-      　SiO2:>99.7%

Whiteness: 92 degrees.   Hardness: 7(Mohs’scale of hardnes)
