Product Q&A

Q:What is the main function of this product in detergent systems?
A:
It serves as a replacement for STPP (Sodium Tripolyphosphate) in detergent formulations, offering a lower price and eliminating phosphorus pollution to water systems.
Q:What are the key chemical properties of this sodium di-silicate powder?
A:
Key properties include a Ca2+ exchange capacity of 550 mg/g min, Mg2+ exchange capacity of 100 mg/g min, SiO2 content of 25% min, and a pH value of 12.5 max.
Q:How does the shelf life of this product compare to standard specifications?
A:
While the COA typically lists a 2-year shelf life, the actual shelf life is much longer if stored in good condition with sealed bags, away from direct sunlight and moisture.
Q:Why can't this product completely replace STPP in all aspects?
A:
STPP enhances emulsifying and dispersing power and acts as an anti-caking agent by absorbing moisture. This product lacks those specific anti-caking and solubility-enhancing features for protein and dust.
Q:What industries can use this product?
A:
It is applicable in the detergent industry, textile and dyeing industry, industrial cleaning auxiliary, and the porcelain industry.
