Alkaline Silica Sol
It is a stable colloidal solution formed by uniformly dispersing nanoscale silica (SiO2) particles in water, with the chemical formula mSiO2·nH2O; its pH ranges from 9 to 11, and the particle size is controllable. It boasts a large specific surface area and excellent adsorption properties, as well as good adhesion, high-temperature resistance, and superior hydrophilicity and oleophobicity.
Large-particle-size silica sol
The average particle size of the large-particle-size silica sol ranges from 30 to 130 nm, with a uniform particle size distribution, excellent stability, and high purity.
Sodium silicate
It appears as a colorless, slightly tinted, transparent or semi-transparent viscous liquid; it is adhesive and highly heat-resistant.
Aluminum sol
Aluminum sol is a stable colloidal solution of nanoscale alumina (Al₂O₃) particles dispersed in water or an organic solvent, typically represented by the chemical formula Al₂O₃·nH₂O. It exhibits properties such as adhesiveness, thixotropy, easy dispersibility, suspensibility, positive charge, adsorption capability, and stability.
