Properties&Applications:
The Anhydrous is white crystal and has strong deliquescence; It is easily soluble in the water and is slightly soluble in the ethanol while not in the ether; It is widely used for producing dye and sulfide and for ore flotation agent, health paper shed agent and cooking on paper.

Packing&Storage:
The massive one is packed in the sealed iron barrel which the thickness is above 0.5mm. Each barrel is net 150kg/200kg. While the flake and granular products are packed in two lays PVC bag inside of PP/PE bag. Each bag is net 25kg/50kg. The packing should be with obvious sign of ?orrosive items? It should be put in ventilation and dry place or under shed asbestos and away from rain and wetting.
