Appearance: white powder, density 2.484 (20 ℃), soluble in water, but insoluble in organic, easy moisture absorption, moisture in the air after the change stick. Easier and metal ions such as calcium, barium, magnesium, copper and iron has dissolved the ability to form compounds; is a good water treatment agent
Packaging:Plastic-woven sack with inner polythene film; net weight at 25kg, 50kg or 1,000kg. Store at a well ventilated, dry place.
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 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.
