Nature:
white or light yellow crystalline powder , relative density is 1.4 . Soluble in
water (when20 ° C, 54g/100ml water; when 100 ° C, 81.7g/100ml water),
acidic aqueous solution. Soluble in glycerine, slightly soluble in ethanol.
Moisture easily decomposed, exposed in the air easily oxidized into
sulfate. Exposure to emit sulfur dioxide and acid generated the corresponding
salts. Heated to 150 ° C decomposition.
10. Packing : External packing is PP woven bag, Internal packing is PE bag,25 kgs, 50 kgs, 1000 kgs, and 1250 kgs bag packing.
11. Storage & defence: Stored in cool and dry place, avoid moisture and heat. No breakage, No mixed with oxidant and toxic matter. The storage period is 6 month since the production date. It should be transported by clean car, with covering matter, avoid rain.
