Product Description

Ammonium sulphate used in leather industry

White granular 2-4mm, no smell. It is easily soluble in water, but insokuble in alcohol and acetone.Easy absorption of moisure agglomerate, with strong corrosive and permeability. Has hygroscopic,moisure absorption into pieces after consolidation. It can completely broken down into ammoniaand sulphuric acid when heated to 513℃above. And it release ammonia when it react with alkali. Low poison,stimulating.

Application

1.In agriculture, used for nitrogen fertilizer. It is a kind of quick action fertilizer,which can make crops thrive and

improve fruit quality and yield and strengthen resistance to disaster, can be used for common soil and plant in

basic fertilizer, additional fertilizer and seed manure. It can be suitable specially for soil with lack of sulfer,

but for acid soil, ammonium sulfate needs to be applied with lime.

2.Raw material of making compound fertilizer.

3.In chemical industry, it is used for raw material in making oxydol, ammonia-alum and ammonium chloride;

4. In Welding Industry, used for welding agent;

5.In textile industry, ued for fire retardant of textile fabrics;

6. In electroplating industry, used for electrobath additive

Shipping

Storage

1.Kept in dry and ventilating place, avoid moisture, water, rain and fire. Avoid shipment with acid,

alkali class, edible orange mix of chemicals. Common transportation tools.

2.Try to not use ammonium sulphate in paddy fields.

Attention

1.Try to not use ammonium sulphate in paddy fields.

2.Ammonium sulphate are acidic fertilizers. It can increase the acidity of the soil, Therefore should pay attention to use in acidic soils with alkaline fertilizer, such as plant ash, phosphate rock powder or calcium magnesium phosphate and so on. Use in neutral and alkaline soil alkaline soils, in order to prevent calcium ion combined with sulfate ion to insoluble calcium sulfate (gypsum), caused by soil hardened, and should apply with organic fertilizer.
