APSM-Active Poly Sodium Metasilicate
A spray-dried powder or granule (density 0.2-0.55g/ml) that iscomprised of -type sodium silicate crystals, amorphous sodium silicate andauxiliary agents.
It is intended for use as 4A zeolite or STPP surrogate innon-phosphorus detergent products.
Characteristics:
1. The Ca/Mg sequestrability of APSM is higher than 4A zeolite and equivalent toSTPP. That results in faster water softening
2. APSM has good compatibility with detergent agents, particularly non-ionicsurfactants. It has moderate detergency when used individually.
3.Excellent water solubility (>15g/100ml).
4. Excellent penetrating, emulsifying, suspending, anti-settling and pH bufferingproperties.
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.
