Microsilica performance
The source the Lei license microsilica is a white amorphous powder, light weight.
Microsilica characteristics
Microsilica fineness: silica fume in fineness of less than 1 micron more than 80%, the average particle diameter of 0.1 to 0.3 microns, specific surface area: 20 ~ 28m / g. Its fineness and specific surface area of approximately 80 to 100 times of cement, fly ash and 50 to 70 times. Quartz powder commonly used specifications of 400 mesh, 800 mesh, 1000 mesh, 1500 mesh and 2000 mesh.
Microsilica purposes
Microsilica can be divided into: paint coating with silica powder, Epoxy with silica powder, rubber, silica powder, sealant microsilica, electronic grade and electrical grade plastic material with silica powder, precision ceramics microsilica.
Paint coating with silica powder
Mesh :600-2500 mesh
SiO2:> 99.5%
Whiteness :70-94
Hardness: (Mohs hardness)
The absorption capacity, low mix viscosity, dispersibility and good fluidity, and stacked to form an angle of repose, rubbing.
2, epoxy floor with microsilica
Mesh :600-1250 Head
SiO2:> 99%
Whiteness :70-94
Hardness: (Mohs hardness)
Low viscosity, good fluidity, good accumulation, compaction, and easy to combine with epoxy resin. Traditional microsilica can save the amount of epoxy resin.
3 rubber microsilica
Mesh :1250-5000 mesh
SiO2:> 99.5%
Whiteness: 70-94 degrees
Hardness: (Mohs hardness)
(1). Wear rubber products
The wear rubber products including rubber plate, tube, tape, roller, it requires rubber compound has good permeability and strong adhesion test results prove fill the microsilica mix fully embodies the rubber dilute permeability, good dispersion, strong adhesion unique properties conducive rubber obliterated and enhance the strength of adhesion between the film and canvas, the tensile strength of the products on the canvas, permanent deformation, mechanical The performance showed significant improvement, especially to enhance the abrasion resistance of the rubber products.
(2) In the application of the silicone rubber products
A very low moisture content, good insulating properties; maximum particle size of less than 5μm, with a certain amount of reinforcing properties.
4 sealant microsilica
Objectives: 1250 Head
SiO2:> 99.5%
Whiteness: 80-94 degrees
Hardness: (Mohs hardness)
The moisture content of less than 0.1% of the treated silica powder, the adhesive strength of the colloid used in the sealant can be increased, yield value, shear force dilution index. With thickening, reinforcing role, tear-resistant, anti-aging role.
5, electronic grade and electrical grade plastic material with microsilica
Mesh :600-5000 mesh
SiO2:> 99.5%
Whiteness:> 90 degrees
Hardness: (Mohs hardness)
The torispherical microsilica for epoxy insulating encapsulating material can be a substantial increase in the filling amount, to reduce the viscosity of the system of the mixed material, to improve the processing performance, improve the penetration ability of the mixture to reduce the coefficient of expansion of the cured product and curing process shrinkage, to reduce the thermal expansion differential.
Precision ceramic with microsilica
Objectives: 5000 Head
SiO2:> 99.7%
Whiteness:> 92 degrees
Hardness: (Mohs hardness)
