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
In many kinds of production activities of our human beings, there are phosphates, such as food, industry, fertilizer, polishing, etc. This is a very rich application field, and in each application field acid.
However, we rarely mention the names of phosphate in our lives. On the one hand, it is because phosphate is not a substance that we will contact in our lives, and it is more in processing, manufacturing, and production.
On the other hand, it is because of more phosphoric acid, one of the components of a certain product appears on the packaging or instruction manual, and the average person will not pay special attention to these.
So today we will talk to you about it. It seems that the “invisible” phosphate in our lives is actually useful:
1. In the pharmaceutical industry, it can be used to make iron phosphate, etc.;
2. You can use yeast nutrition or acidic agents such as cola, beer, candy, coloring oil, dairy products, drinks, etc. in the food industry;
3. It can be used to produce refractory cement. This cement can increase the service life of steel refiners to a certain extent;
4. Using its own chemistry can become a metal rust paint in the coating industry to reduce material loss;
5. It can be used to configure a cleaner. This cleaner is particularly suitable for removing the stains that will appear on the printing version of the printing in the printing industry;
6. You can polish aluminum products because it can be used to configure chemical and electrolytic polishing fluids to phosphorize metal surfaces;
7. When the rubber pulp is needed during the production process, it can be used as a raw material for coagulants and inorganic binders;
8. It is also the most common purpose in us, which is to use it to produce high -concentration of phosphate fertilizer and compound fertilizer.
In addition, there are drug -grade phosphates that can be used for pharmaceutical manufacturing, polymer phosphates for manufacturing polyphosphoos, organic synthetic raw materials, etc. These are all applications of phosphate.
