Precipitated silica is an amorphous silicon dioxide powder produced through a wet chemical precipitation process. It features high porosity, large surface area, ಮತ್ತು low bulk density, making it ideal for a variety of industrial uses — including tires, ಪ್ಲಾಸ್ಟಿಕ್ಗಳು, ಲೇಪನಗಳು, agrochemicals, ಟೂತ್ಪೇಸ್ಟ್, and animal feed.
ಉತ್ಪಾದನಾ ವಿಧಾನ: Wet Precipitation
KosNature manufactures precipitated silica using a controlled chemical process:
Basic Reaction:
Na₂SiO₃ (Sodium Silicate) + H₂SO₄ (Sulfuric Acid) → SiO₂ (precipitated) + Na₂SO₄ + H₂O
Process steps include:
- pH Control
- Reaction temperature & dosing rate optimization
- Gel aging, ಶೋಧನೆ, ಮತ್ತು ಒಣಗಿಸುವುದು (ಉದಾ., spray drying)
- Particle size and structure adjustment via milling
This process ensures consistent product quality and allows for specification customization.
