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.
