Detailed explanation of the role and use of phosphate

Phosphate is a widely used food additive in the food industry. In addition to its application in food, it is also used in agriculture and chemical industries. The function and use of phosphate are explained in detail below.
agricultural industry
In agriculture, phosphate is one of the three main nutrients for plants and a major component of fertilizers. Phosphate fines are mined from the phosphorus layer of sedimentary rocks and can be used without processing after mining, but unprocessed phosphates are only used in organic farming. Generally chemically processed into lime superphosphate, double superphosphate or ammonium dihydrogen phosphate, their concentration is higher than that of phosphate, and they are more soluble in water, so plants can absorb them faster.
Food Industry
Phosphorus is an important mineral element necessary for the human body. The main source of phosphorus intake by the human body is natural food or food phosphate additives. It fully exerts its synergistic effect with other additives. Therefore, phosphate is the most It is one of the most widely used food additives. As an important food ingredient and functional additive, it is widely used in meat products, poultry products, seafood, fruits, vegetables, dairy products, bakery products, beverages, potato products, seasonings , in the processing of instant food, etc.
Phosphate is used as a binder in refractory materials. Most of the binders prepared by reacting phosphoric acid with alkali metal or alkaline earth metal oxides and their hydroxides are gas-hardening binders, that is, they can coagulate and react at room temperature without heating. hardening effect. Acid salts used as binders for refractories have strong bonding strength in the medium and low temperature range before ceramic bonding, and are widely used as binders for unshaped refractories and unburned refractories.
Water treatment in boilers
In addition to being used as a scale inhibitor for boilers, phosphates can also be used as corrosion inhibitors, which can effectively produce scale and alkaline corrosion in boilers.
