Predominance

Mainly used by mill run,pesticide,dye,leather production and organic compound.Comapred with other company,high purity,not easy to be intenerated,especially less iron,sodium sulfide,sodium carbonate,insolubles impurity in water,dip-dying in the leather production,it can disperse the fiber equably,less iron insure the appearance and good quality of leather.

Poduction Method

Absorb sulfureted hydrogen(H2S) through subtractive ionic film.
