3. Used:

(1)Ammonium sulfate is mainly used as fertilizer for a variety of soil and crops.

(2 )can also be used in textile, leather, medicine and so on.

(3 )consumption from the industrial ammonium sulfate ammonium sulfate dissolved in distilled water, except the addition of arsenic and heavy metals in solution purification agents, filtration, evaporation, cooling crystallization, centrifugal separation, drying. Used as foodadditives, as dough conditioner, yeast nutrients.

(4 )used in biochemistry, common salt, salting, salting initially be upstream from the fermentation products of purified proteins.

 

4. Handling Precautions:

Closed operation, local exhaust. The operator must go through specialized training, strict compliance with operating procedures. Proposed operators wear self-absorption filter respirators, wear chemical safety glasses, wear protective overalls on infiltration, wear rubbergloves. To avoid dust. Avoid contact with acids, alkalis contact. Handling of light when light unloading, packaging and containers to prevent damage. Equipped with emergency equipmentleakage. Empty containers may remain hazardous materials.

 

5. Storage:

Store in a cool, ventilated warehouse. Away from fire and heat. Should work with acids, bases stored separately and avoid mixing reservoir. Storage areas should be equipped with a suitable host material spill.
