Steel grade Ammonium Sulphate
Ammonium Sulphate
CAS NO.:7783-20-2
EINECS NO.:231-984-1
H.S.Code:31022100
Molecular formula：(NH4)2SO4
Features:
Industrial ammonium sulphate is white or light grey crystal. Relative density D=1.769,235℃ decomposition. It is hydroscopic, and apt to dissolve in water(not in alcohol or acetone),and it will become solid blocks when absorbing moisture. The aqueous solution is alkalinous. It reacts with alkali to release ammonia gas.
Application:
It is mainly used to manufacture compound fertilizer, potassium sulfate, ammonium chloride, ammonium per sulfate, etc.; it can also be used to mine rare earth ores.
Package:
Multi-layer bag (outer bag plastic woven bag, inner bag polyethylene film bag) or composite plastic woven bag (plastic woven cloth/film) packaging 25KG/50KG, or ton package, can be customized according to customer requirements
Storage and transportation：
It can be transported by vehicles such as cars, trains, ships, etc. During the transportation process, it should be protected from moisture and packaging bags. It should be stored in a flat, cool, ventilated and dry warehouse. It is strictly forbidden to contact with lime, cement and other alkaline substances or store it in the same warehouse. The stacking height of the package should be less than 7m.
