Silica Powder As Precipitated Silicon Dioxide Used For Industrial Coatings

 

 

Introductions

 

Precipitated silica is a silica (SiO2) produced by precipitation from a solution containing silicate salts. The production of precipitated silica starts with the reaction of an alkaline silicate solution with a mineral acid. Sulfuric acid and sodium silicate solutions are added simultaneously with agitation to water. Precipitation is carried out under alkaline conditions. The particles are porous. Primary particles with a diameter of 5 - 100 nm, and specific surface area 5-100 m2/g. Agglomerate size is 1 - 40 µm with average pore size is > 30 nm. Density: 1,9 - 2,1 g/cm3.

 

Feature

 

In the natural rubber or synthetic rubber adhesive, Silica has high transparency and good mechanical properties, provides thixotropy and reinforcing performance, can greatly improve the vulcanized rubber tensile strength and abrasion resistance, and its malleability can improve the adhesion force also.

 

Application

 

1, Unsaturated Polyesters: Avoid drop lets and wrinkles.

2, Pigment: Prevents precipitation, improves dye absorption, and improves the dispersion ability.
