New type builder of STPP substitutes
New type 4A zeolite
Performances and features:
It uses nature zeolite with activation process, then mixed with
other kind of builder. Environmental protected, the STPP substitution.
In detergent powder, it not only improve the washing performance,
but also do the powder appearance quality, maintain loose, good
fluidity. In soap and soap cream production, the cream formation
effect good, no crystallization, good whiteness, strong washing
performance, and decline the above product greatly.
The index is as follows:

General performance of PMA in detergent application:
 Chelate Ca2+ and Mg2+ cation in hard water |
Incarnate macromole's ability to soften hard water |
Mechanism of action: The
chelation strength of PMA homopolymer is obviously higher
than copolymer |
Decentralize calcium carbonate |
Inhibiting action on the growth of calcium carbonate crystal. |
| Decentralize and suspend calcium carbonate |
| To prevent it from depositing on clothings |
| The decentralization ability on calcium
carbonate of PMA copolymer is obviously higher than homopolymer
|
| PH value of buffer solution |
| Stability of macromole in acid and alkali system |
| Adaptability to detergent |
| Persistent ability in laundering |
| Suspend and decentralize ability for solid particle |
| Deflocculation to dirt |
| Anti sedimentation degree to precipitation |
| Mechanism action: Utilize electrostatic repulsion and steric hindrance to decentralize solid particle |
PMA macromolecule polymer used in detergent chemical
field
Improve the performance of detergent powder:
|
Partially or completely substitute STPP, which solve the environmental protection problem |
| |
Improve the detergent powder washing performance |
| |
Improve dirt anti-deposit capacity, alternate CMC |
| |
Greatly decline the CaCO 3 deposit in clothes |
| |
Good builder in low temperature |
| |
Buffer PH value, lower the incentive on human skin |
Note: PMA in phosphorus powder with STPP is good
for washing performance.
Improve the detergent powder production process:
|
Build-up granule finish degree and strength. |
| |
Decline slurry viscosity |
| |
Greatly decline fine powder production |
| |
Improve drying efficient, energy-saving is dramatically |
| |
Improve slurry disperse and uniformity. |
| |
Improve blending and pump delivery efficiency |
