Product Q&A

Q:What is the main function of this product in detergent systems?
A:
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 chemical exchange capacities of this product?
A:
The product has a Ca2+ exchange capacity of 550 mg/g (min) and a Mg2+ exchange capacity of 100 mg/g (min).
Q:Is this product suitable for use in low-temperature water?
A:
Yes, it features good performance in low-temperature water and strong pH buffering ability.
Q:What is the shelf life of this product?
A:
While the COA typically lists 2 years, the actual shelf life is much longer if stored in good condition (sealed bags, away from sunlight and moisture).
Q:How does this product compare to STPP regarding caking?
A:
Unlike STPP which acts as an anti-caking agent by absorbing moisture, this product does not have the same moisture-absorbing properties, so it cannot completely replace STPP's anti-caking function.
