1. Detergent industry
2. Construction industry
Functions in detergent industry:
1. pH buffering agent
2. Suspension agent
3. Emulsifying and detergent solution and stabilizing foam
4. Slurry modifier in powder detergent, and stabilizing STPP in the detergent solution
5. Rust inhibitor for equipment, especially for aluminum and copper made parts
6. Removing Mg2+ ion in water when used together with soda ash
1. Sodium silicate can be made from different raw material, the mostly used are:
- Sodium Sulphate + quartz sand (we call it SSA process)
- Soda ash + quartz sand (we call it Soda Ash process)
According to Rawchem's experience, SSA process product can not be used in detergent industry due to its color and quality stability problems, so we only use soda ash process for detergent industry clients
2. There are different types of sodium silicate, just by the name "sodium silicate", normally we can not define which item exactly it is, to quote or offer, we need to know the following info:
- Liquid or solid
- Modules
3. We normally list 3 years as the shelf life in our COA, the real shelf life is actually much longer than 3 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
