What Is The Relationship Between 4A Zeolite And Sodium Tripolyphosphate?

Feb 06, 2023

4A zeolite acts in a different way than sodium tripolyphosphate, which forms acid complexes with calcium and magnesium ions that make water hard. 4A zeolite is an exchanger. 4A zeolite has no emulsification, dispersion ability, calcium ion exchange rate is slow, magnesium ion exchange ability is very weak. The exchange capacity of 1.2 parts zeolite is equivalent to 1 part anhydrous sodium tripolyphosphate. However, 4A zeolite is an insoluble additive and tends to be deposited in the washing solution. A certain dispersant is usually required. Dispersant mainly polyacrylic acid salt, acrylic acid and C4H2O3 copolymer, etc.
