Powder Ammonium sulphate Steel grade

Powder Ammonium sulphate Steel grade
  Ammonium sulphate
  CAS NO.:7783-20-2
  EINECS NO.:231-984-1
  H.S.Code:31022100
  Molecular formula : (NH4)2S04
  Features:
  Industrial ammonium sulphate is white or light grey crystal.lt is hydroscopic,and adt 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.
  Product types:
    Steel grade:It is a by-product from steel.
  Specitication:Nitrogen- ≥20.5%;Moisture- ≤1%.
  Applicotion:Used for production of complex fertilizers,potassium sulfate,ammonium chloride and ammonium persulfate,ect;Also can be used in rare-earth ore processing.
  Pressing granular:lt is extruded by steel grade.
  Specitication:Nitrogen- ≥20.5%;Moisture- ≤1%;Size:2-5mm;Hordness:22-24N/mm2
  Application:Mainly used for chemical fertilizers in Commercial Crops.
  Package:
  Packed in PP woven bags with PE film liner,Net weight of each bag:25kgs,50kgs,l000kgs.
  Storage:
  Stored in a cool,dry and ventilated warehouse.It must not be put together with Alkali stuffs,such as lime,cement,etc.Do not expose it to sunlight and rain during transporation.Do not damage the packing bags.
