详情

♦ Silica sol belongs to colloid. It is tasteless and nontoxic, the chemical molecular formula is mSiO2.nH2O.

 

♦ Since the colloid grains are minute(10~20nm) and have relatively large specific surface area, the grains themselves are colorless and transparent, so they do not affect the natural color of the material to be covered.

 

 With low viscosity, it can soak the places whtere water soaks, therefore, it presents excellent dispersion and permability when being mixed with other substances.

 

♦ When the moisture contained in silica sol are evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.

♦ Used as the cohesive agent for various fireproof materials. It has high bounding strengthe and high heat-resisting per-formance(1500-1600C), etc.

 

♦ Used in coating industry. It makes the paintsfirm. It also possesses features, such as anti-contamination, dustproof, anti-aging, fireproof, ect.

 

♦ Used in precision casting of thin covers to increase the cover strength, improve the casting smooth finish. Its molding quality is better than that of water glass. It can be used to replace ethy l silicate for molding so as to reduce the costs and help improve the operating conditions.

 

♦ Having large specific surface area, silica sol can be used for making catalyst and as catalyst carrier.

 

♦ Used in paper-making industry. It can be used as the anti-glutinous agent of cellophane, pre-treatment agent of photopraphic paper, skidproof agent of cement bags,etc.
