Characteristics: being a kind of polymer transparent glass flake, or white, crystalline powder. Hygroscopic and strong, After hygroscopic become sticky, easy in the air ChaoXie, soluble in water, Solubility in water, but the dissolution rate is warm, Aqueous acid reaction in. Easily hydrolyzed to phosphate. For some metal ions (calcium and magnesium) has the ability to generate soluble complex, it can be used to soften water, and lead, silver, a salt can also generate complex.
 

Packing: 25 kgs in net bag, 23 mts in the 20’ FCL

Usage: For industrial use, such as oil field, paper-making, textile, dyeing, petrochemical industry, tanning industry, metallurgical industry and building material industry, it is mainly used as a water softening agent in solution for printing, dyeing, and boiler; Diffusant in papermaking; slow corrodent, floating agent, dispersing medium, high temperature agglomerant , detergent and soil analytical chemistry reagent. For food grade, it is mainly used as additive agent, PH adjusting agent and fermentation agent, and nourishment.
