Remark: Effective constituent refers to the effective content of PAA
Description: Build-up granule finish degree and strength. Decline slurry viscosity and fine powder production. Improve drying efficient, energy-saving,and slurry disperse and uniformity,and Improve blending and pump delivery efficiency. Improve the detergent powder washing performance and dirt anti-deposit capacity, alternate CMC. Greatly decline the CaCO3 deposit in clothes, Good builder in low temperature. Buffer PH value, lower the incentive on human skin.Incarnate macromole's ability to soften hard water. The chelation strength of PAA homopolymer is obviously higher than copolymer
Application: PAA macromolecule polymer used in detergent chemical field

Description: To exchange Calcium and Magnesium capacity is higher than 4A Zeolite, it is equivalent to STPP, water soften speed is quick, soften capacity is strong and temperature scope is wide.Good compatibility with many kinds surfactant (especially non-ionic surfactant), and with self-consistent stain removable ability. Good characteristic of penetrate, emulsification , suspension and anti-deposit for stain, PH buffering capacity is strong. The product has good whiteness, fluidity and stability.It is easy to solute in water.Effective and environmental protection, high performance to price, which can reduce the detergent powder cost.
Application: It is applicable to the slurry preparation, post-blending etc process,and can be combined with STPP to produce low-phosphorus detergent powder.
