We have carved a niche as one of the foremost Hydrated Calcium Silicate Manufacturers in India. Calcium Silicate Hydrate has widespread industrial applications. Synthetic Hydrated Calcium Silicate is used as anti-caking, reinforcing and carrying agent in several industries.
Production Process
Sodium Silicate and Calcium Sulphate are reacted together under precisely controlled conditions to give a slurry of Calcium Silicate and Sodium Sulphate in solution. By stringent control of parameters such as temperature, pH, electrolyte concentration, agitation and reaction time, Silicate of required structure and surface characteristics is produced.
The slurry is then filtered and washed with water to remove sodium sulphate. The filter cake is subsequently dried and then milled to the required particle size distribution. Finally the silicate is collected, deaerated, and packed at a controlled bulk density.
