4A Zeolite

Zeolite 4A has strong adsorption
capacity and makes preferential
adsorption of certain gas and
liquid molecular according to
relative intensive of molecular
formula chemical polarity. It
also has Ca2+, Mg2+ exchange
capacity. As builder of synthetic
detergent, it can replace STPP.
New type 4A zeolite is alkaline
in solution, with buffer action,
dispersivity and antiredeposition
performance, as well as synergism
with surfactant
