FEED ADDITIVES:
It is widely used as an ideal phosphorus source for fish and shrimp feed, especially for young fish and shrimp feed.The water
solubility of anhydrous sodium dihydrogen phosphate can ensure the full utilization of phosphorus by fish and shrimp aquatic
animals, which not only reduces the cost of aquaculture, but also reduces the water pollution caused by the loss of phosphorus
source in the process of aquaculture, thus meeting the requirements of environmental protection to a greater extent.


FOOD INDUSTRY:
In food industry and fermentation industry, it can also be used as buffering agent, raw material of baking powder, adhesive and curing agent for bread and sauce, sour agent for powder, and quality improver for evaporated milk.Also can make cheese and other dairy products, meat, fish products stabilizer, binder, baking powder buffer, salting with mixed salt, etc.


INDUSTRIAL USE:
Sodium dihydrogen phosphate is used for boiler water treatment and electroplating.It is a raw material for the manufacture of sodium hexametaphosphate and polypolyphosphate.It is also used in the manufacture of detergents, metal detergents, and as dyes and pigment precipitators.
