Appearance:

White powder, density 2.**4(*0), soluble in water but insoluble in organic solvert, it has got strong hygroscopicity and can absorb humidity from the air to become into pasty form, it may form soluble chelates with ions of Ca, Ba, Mg, Cu, Fe etc. and it is a good water treatment chemical.

Application:

1. 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.

2. For food grade, it is mainly used as additive agent, PH adjusting agent and fermentation agent, and nourishment.
