The bulk density (20-200 for 1.5), the chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in…
Self insulation block silica fume
Composite insulation block is based on the current status of the new wall materials industry development, with high performance microsilica hollow block as shell, fill light thermal insulation materials such as foam micro silica fume powder or polystyrene foam, microsilica density and heat preservation material injection molding into the entirety and form silica fume block with building envelope and heat…
Special micro silica fume powder in wear-resistant floor
The silica fume in wear-resistant floor can fully disperse, filling in the gap between the cement particles, the slurry is more dense, microsilica volcano ash activity index reached 110, effectively substitution coefficient reach 3-4, especially after cement hydration Ca (OH) 2 have strong absorption, form well developed calcium silicate gel, greatly enhance the strength of the floor. Strength increase: when…
Silica fume hs code factory
Silica fume HS code: 25120090 Silica fume with less than 1µm is more than 80%, the average particle size is 0.1 - 0.3 um, pecific surface area: 20 - 28m2/g. The fineness and specific surface area are about 80-100 times of the cement and 50-70 times of the fly ash.
Condensed silica fume in concrete factory
Composition: Condensed silica fume consists primarily of pure silica in non-crystalline form and contains more than 90% silicon dioxide. Small amounts of magnesium, iron, and alkali oxides are also present. Most particles are smaller than 1 mm with an average diameter of 0.1 mm. ASTM C 1240 limits the percent retained on the 45-mm sieve to 10%, the moisture content…
Buy ceramic admiture silica fume
Silica fume (microsilica) is produced in the arc fusion process when silica is separated from Zirconium Silicate. The resulting fume is very fine amorphous material with purity above 87%, a BET surface area of 12-20 m2/g, and pH range of 5-8. There are hundreds of industrial uses for fumed silica in sealant formulations, rheology control, and emulsification agents.
Super dispersibility undensified microsilica
The undensified microsilica describes condensed silica fume sourced directly from a silicon or ferro silica furnace; the bulk density at source can be as low as 150kg/m3 and has the consistency of a thick smoke. The bulk density of undensified silica fume is <400 kg/m3. Naturally occurring amorphous silica can have bulk densities in the same range as undensified silica…
