Use:
Agriculture use:raw material of phosphate fertilizerand feed nutrients
Industry use: chemical raw materials
1.Protect the metal from corrosion
2.Mixed with nitric acid as chemical polishing agentto improve the surface finish of metal
3.Material of phosphatide which is used for producewashing product and insecticide
4.The production of phosphorus containing flameretardant materials.
Food additives use:acidic flavoring,Yeast Nutri-ents, ,such as coca-cola.
Medical use:to produce medicine containing phos-phorus,such as Na 2 Glycerophosphat
A comprehensive standardized enterprise with independent intellectual property collection, development, production, sales, service, exports.
Phosphoric acid is a common inorganic acid, which is H3PO4. It is not easy to volatilize, it is not easy to break down, and it is easy to disintegrate in the air. Phosphate is a medium -intensity, and its crystallization point is 21 ° C. When the temperature is lower than this temperature, the crystallization of semi -water objects will be precipitated. Heating will lose water to get scoring phosphate, and then further water loss to get polar acid phosphoric acid. Phosphoric acid has acidity, and its acidity is weaker than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid and boric acid.
Medicine: Phosphoric acid can be used to make phosphate -containing drugs, such as sodium glycerol phosphate. Agriculture: Phosphate is an important raw material for producing phosphate fertilizer (calcium phosphate, potassium dihydrogen phosphate, etc.), and is also a raw material for producing feed nutritional agents (calcium phosphate);
Food: phosphate is one of the food additives. It is used as acidic and yeast nutrition agents in food, and Coca -Cola contains phosphate. Phosphate is also an important food additive, which can be used as a nutritional enhancer;
Industry: phosphate is an important chemical raw material, the main role is as follows;
1. Treatment of the metal surface and generate a refractory phosphate film on the metal surface to protect the metal from corrosion;
2. Mixed with nitric acid as a chemical polishing agent to increase the smoothness of the metal surface;
3. The raw material phosphate for production of washing supplies and pesticides;
4. The raw material for the production of phosphorus -containing flame retardants;
