Phosphoric acid use
Application 1: Mainly used in phosphate industry, electroplating, polishing industry, sugar industry, composite fertilizer and so on. In the food industry as sour agent, yeast nutrition agent, etc
Application 2: Mainly used for making chemical fertilizers, detergents, food and feed additives, flame retardants and various phosphates
Use 3: Commonly used as an analytical reagent
Use 4: For capacity and colorimetric analysis
Application 5: In the production of silicon flat tube and integrated circuit, aluminum film is commonly used as electrode lead, and it is necessary to lithograph aluminum film and use phosphoric acid as acid cleaning etch agent. It can be formulated with acetic acid.
Use six: Can be used as sour agent and yeast nutrition. It can be used as a sour agent for seasonings, cans and refreshing drinks. Used in brewing yeast nutrition source, to prevent the reproduction of miscellaneous bacteria.
Use seven: Wet phosphoric acid is mainly used for the manufacture of various phosphates, such as ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate and condensed phosphates. Refined phosphoric acid is used to make calcium hydrogen phosphate for feed. Used for metal surface phosphating treatment, preparation of electrolytic polishing liquid and chemical polishing liquid for polishing aluminum products. The pharmaceutical industry is used to manufacture sodium glycerophosphate, iron phosphate, etc., and is also used to manufacture zinc phosphate as a dental filling adhesive. Used as catalyst for condensation of phenolic resin, desiccant for production of dyes and intermediates. A cleaning solution used in the printing industry to remove stains from offset color plates. It is also used to prepare match stem impregnation solution. The metallurgical industry is used to produce phosphoric acid refractory mud to increase the life of steel furnaces. It is the coagulant of rubber slurry and the raw material for the production of inorganic binder. Coatings industry used as metal anti-rust paint.
Use 8: As yeast nutrition agent, chelating agent, antioxidant synergist and inorganic acid agent, acid degree of 2.3 ~ 2.5, can be used for compound seasoning, canned, cheese, jelly and cola drinks, according to the production needs of appropriate use.
Application 9: Mainly used in ethylene hydration to produce ethanol catalyst, high purity phosphate, pharmaceutical manufacturing, chemical reagents.
Use 10: determination of chromium, nickel, vanadium components in steel, metal rust prevention, rubber coagulant, determination of serum non-protein nitrogen, total bile alcohol and whole blood glucose. Crystalline phosphoric acid is mainly used in microelectronics, high-energy batteries, laser glass and other manufacturing processes, as high purity catalysts, medical materials.
