The Advantages
of Ammonium Sulfate:
An excellent nitrogen fertilizer (commonly
known as fertilizer powder), suitable for general soil and crops, can make
branches and leaves grow vigorously, improve fruit quality and yield, enhance
crop resistance to disasters, can be used as base fertilizer, topdressing and
seed fertilizer. It can produce ammonium chloride by double decomposition
reaction with salt, and ammonium alum by action with aluminum sulfate, and make
refractory materials together with boric acid. Adding electroplating solution
can increase electrical conductivity. It is also the catalyst of food sauce
color, the nitrogen source of yeast culture in the production of fresh yeast,
acid dye dyeing aid, leather deashing agent. In addition, it is also used in
beer brewing, chemical reagents and battery production. Another important role
is the mining of rare earth, the mining of ammonium sulfate as raw materials,
the use of ion exchange form to exchange the rare earth elements in the mine
soil, and then collect the leaching solution to remove impurities,
precipitation, pressing, burning into rare earth raw ore, about 5 tons of
ammonium sulfate per mining production of 1 ton of rare earth raw ore.
There are also many biological uses, mostly
used in protein purification process, because ammonium sulfate is an inert
substance, not easy to react with other bioactive substances, in the
purification process can maximize the protection of protein activity, in
addition, ammonium sulfate is extremely soluble, can form a high salt
environment, for protein precipitation and subsequent high salt purification
preparation.
Application:
It is mainly used as a fertilizer, as a
nutritional supplement to supply nitrogen and sulfur, and is widely used in
agriculture.
It has a high solubility in water and can
also be used as a coolant for aqueous solutions.
It can also be used to prepare other
compounds, such as metal sulfides in the laboratory.
Packing:
In 25kg net plastic woven bag or according
to client's requirement.
