Trimeric sodium phosphate detergent auxiliary agent is a kind of excellent properties, is one of the biggest component of detergent consumption during the production, it has four aspects: 1, chelation of heavy metal ions, heavy metal ions in the water in the washing process can be combined with the detergent molecules into insoluble metal salts, lower the washing ability, even completely.Therefore, detergent must be added to make the heavy metal ions in the water into harmless chelating agents.Sodium tripolyphosphate has a strong chelating effect on heavy metal ions
