Keyway Industrial Limited Colloidal silica What is Colloidal Silica/ Silica Sol? Colloidal silica is a dispersion of amorphous silicon dioxide (silica) particles in water. These amorphous silica particles are produced by polymerizing silica nuclei from silicate solutions under alkaline conditions to form nanometer sized silica sols with high surface area. A charge is then induced on the silica nanoparticle surface that allows the silica particles to repel one another and form a stable dispersion, or colloid. Colloidal Silica Characters: Colloidal silicas are produced in a variety of grades that range in a number of factors. Particle size typically varies from 5nm to 40nm, and particle size distribution can vary from narrow to wide depending on the manufacturing process. Standard colloidal silica is stable at a pH from 8 - 10.5 and carries an anionic surface charge that is stabilized with sodium or ammonium. In certain grades, some of the silicon atoms in the silica particle are replaced with aluminate ions to allow for enhanced stability in a wider pH range, usually 3.5 - 10.5. Colloidal Silica Application: Densification of concrete, cement, and other materials. Fine retention in paper manufacturing. Enhanced bonding of waterborne adhesives. Improved surface friction and anti-slip properties. Wastewater filtration flocculant. Investment casting binding. Anti-soilant textile coatings.

The use of refractory cement in boiler construction is also very large, and refractory cement is also a refractory castable that we need most. Refractory cement is also called aluminate cement. The raw material of aluminate cement is bauxite and limestone. It is made of calcined, with calcium aluminate as the main component, clinker with alumina content of about 50%, and then ground into hydraulic cementitious material, which is also a kind of special cement. The thermal stability of refractory cement is good. The aggregate is almost all clinker. The expansion and the shrinkage of the cement are low. Therefore, the thermal expansion of the masonry is smaller than that of the brick, the temperature stress is relatively small, and the structure is also various. Reticulated, needle-like, chain-like crystalline phase, strong resistance to air temperature, for example, used to cast soaking furnace mouth and furnace cover, the furnace age can be extended to one and a half years; and the fire resistance of refractory bricks and the same The texture of the refractory brick is similar, but because the refractory cement does not have a net more sintering, the initial blasting shrinks larger, so the load softening point is slightly lower than the refractory brick, but as a whole, the refractory cement is still due to the refractory brick.
Brown fused alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2200. A slow solidification process follows the fusion, to yield blocky crystals. The melting help in removing residual carbon , Strict control over Titania levels during the fusion process ensures optimum toughness of the grains. Then The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use. Taiyue brown fused alumina is with high purity,high crystallinity,lower expansion coefficient,refractoriness above temperature 1900. It is the best raw material for refractory.
