Properties: white powder, density is 2.484(20 Centigrade), easily soluble in water, but not in organic solution, absorbent to dampness, and turn sticky when absorbed dampness in air. It is possible to form solvent compound with metallic ions such as Ca, Ba, Mg, Cu and Fe, it is a fine agent for water treatment.
Application: 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 a water softening agent in solution for printing, dyeing and boiler. Diffusant in paper making, slow corrodent , floating agent, dispersing medium, high temperature aggcomerant, detergent and soil analytical chemistry reagent. For food grade, it is mainly used as additive agent. PH adjusting agent and fermentation agent and nourishment.
