Predominance: mainly used by mill run, pesticide, dye, leather production, water treatment and organic compound.
Compared with other company, high purity, less impurity, not easy to be inten-erated, especially less iron, sodium sulfide, sodium carbonate, insolubles impurity in water. dip-dying in the leather production, it can disperse the fibre equably. less iron insure the appearance and good quality of leather.
