Why can't MSD completely replace STPP?

STPP has unique features like enhancing emulsifying and dispersing power to increase protein and dust solubility, and acting as an anti-caking agent by absorbing moisture to keep powder free-flowing.

What are the physical specifications of the powder?

It appears as a white granular powder with a purity of 95% min, SiO2 content of 25% min, pH value of 12.5 max, and whiteness of 85% min.

Product Q&A

Q:What is the main function of this product in detergent systems?

It is designed to replace STPP (Sodium Tripolyphosphate) in detergent formulations, offering a lower price and eliminating phosphorus pollution to water systems.

Q:What are the key characteristics of this sodium di-silicate powder?

Key characteristics include good water softening capability, strong pH buffering ability, excellent performance in low-temperature water, and compatibility with various surfactants and bleaching agents.

Q:What is the shelf life of this product?

While the COA typically lists a 2-year shelf life, the actual shelf life is much longer if stored in good conditions (sealed bags, away from direct sunlight, moisture, and incompatible chemicals).

Q:How does this product compare to STPP and Zeolite?

It serves as a phos-free alternative to STPP and overcomes Zeolite's disadvantages. It has a higher Ca2+ exchange capacity (550 mg/g) compared to Zeolite (295 mg/g) and offers better bulk density and loading quantity than Zeolite.

Q:What are the main applications of this product?

It is primarily used in the detergent industry, textile and dyeing industry, industrial cleaning auxiliaries, and the porcelain industry.
