Product Description:
Phosphoric acid is a common inorganic acid and is a medium to strong acid. Its acidity is weaker than strong acids such as sulfuric acid, hydrochloric acid and nitric acid, but stronger than weak acids such as acetic acid, boric acid and carbonic acid. Phosphoric acid reacts with sodium carbonate at Chemicalbook different pH to produce different acid salts. It can stimulate the skin to cause inflammation and destroy muscle tissue. Concentrated phosphoric acid has an erosive effect when heated in porcelain. It is hygroscopic, keep it sealed.
Application:
(1)Mainly used in phosphate industry, electroplating, polishing industry, sugar industry, composite fertilizer and so on. In the food industry as acidifier, yeast nutrient, etc..
(2)Mainly used as catalyst for ethylene hydration to produce ethanol, high purity phosphate, pharmaceutical manufacturing, chemical reagent.
(3)Mainly used in the manufacture of chemical fertilizers, detergents, food and feed additives, flame retardants and various phosphates.
(4)In the production of silicon plane tube and integrated circuits, commonly used aluminum film for electrode leads, the need for photolithography of aluminum film, using phosphoric acid as an acidic cleaning corrosive. It can be formulated with acetic acid.
(5)Can be used as souring agent and yeast nutrient. Can be used as souring agent for seasonings, canned goods, and refreshing drinks. Used as yeast nutrient source in brewing to prevent the propagation of stray bacteria.
(6)Wet phosphoric acid is mainly used to make various phosphates, such as ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, etc. and condensed phosphates. Refined phosphoric acid is used to make calcium phosphate for feed. Used for metal surface phosphating treatment, formulated electrolytic polishing solution and chemical polishing solution for polishing aluminum products.
(7)Pharmaceutical industry for the manufacture of sodium glycerophosphate, iron phosphate, etc., but also for the manufacture of zinc phosphate as a dental Chemicalbook dental fillings adhesive. Used as a catalyst for phenolic resin condensation, dyes and intermediates production of desiccant. Printing industry for the preparation of wipe offset color printing plate stains on the cleaning solution. It is also used to formulate impregnating liquid for matchsticks. Metallurgical industry for the production of phosphoric acid refractory mud, improve the life of steelmaking furnace. It is the solidifying agent of rubber paste and the raw material for producing inorganic binder. Used in paint industry as antirust paint for metal.
(8)Determination of chromium, nickel, vanadium composition in steel, metal rust prevention, rubber coagulant, determination of non-protein nitrogen in serum, total cholesterol and whole blood glucose and so on. Crystallized phosphoric acid is mainly used in microelectronics, high-energy batteries, laser glass and other manufacturing processes, as a high-purity catalyst, medical materials.
