2) APPLIFICATION
4A Zeolite is mainly used on detergent powder take the place of sodium tripolyphosphate as the soft water additives, also used as adsorbents, dehydrating agent and a catalyst. Its role is as follows:
       1, alkaline, there is a buffer effect ;
       2, and anti-redeposition agent is good;
       3, surface active agents have a synergistic effect;
       4, the slurry viscosity, to prevent caking;
       5, good degradation of environmental security.
       In liquid detergents, due to the problem of water-soluble, the amount of 4A zeolite is small, mainly used for washing powder or paste cleaner.
