Characteristics:
1. The Ca/Mg sequestrability of APSM is higher than 4A zeolite and close to STPP.
2. APSM has good compatibility with detergent agents, particularly non-ionic surfactants. It has moderate detergency when used individually.
3. easily dissolves in water, Excellent water solubility (>15g/100ml).
4. Excellent penetrating, emulsifying, suspending, anti-settling and pH buffering properties.
5. High whiteness
6. APSM can significantly improve fluidity of stock liquid (pre-drying) and allowhigher solid content, thus reduce energy cost.
7. Ideal surrogate for 4A zeolite.
Application:
APSM is widely used in washing-powder/detergent/printing/dyeing auxiliary agent / textile auxiliary agent industries。
