Zinc oxide manufacturers of phosphating liquid: Uses of zinc oxide

Zinc oxide manufacturers of phosphating liquid: Requirements and characteristics of zinc oxide for phosphating liquid. Zinc oxide manufacturers of phosphating liquid believe that the requirements for zinc oxide in phosphating liquid are relatively high. First of all, the content of zinc oxide. From the reaction formula, if the zinc oxide content in the zinc phosphate reaction does not reach the standard or the purity is insufficient, two situations will occur. More raw materials that can react with phosphoric acid will be used, and the generated substances will also affect the purity of the product.

　　Zinc oxide manufacturers for phosphating liquid believe that the requirements for zinc oxide in phosphating liquid are relatively high. First, the zinc oxide content. From the reaction formula, if the zinc oxide content in the zinc phosphate reaction does not reach the standard or the purity is insufficient, two situations will occur: there will be more raw materials that can react with phosphoric acid, and the generated substances will also affect the purity of the product.

　　In the second case, substances that cannot be dissolved by acid will be deposited at the bottom in the form of a cartridge. Second, the lead content. High lead content will affect the transparency of the phosphating liquid. Generally, the zinc oxide produced by the indirect method is 99.7%, with very low requirements for impurity content (because zinc can be completely dissolved during the heating process of the solvent). Zinc oxide mainly provides zinc ions in the phosphating liquid and is the main component of the phosphating film. Mutual trust in the phosphoric acid reaction refers to zinc phosphate, which can be used for corrosion and rust prevention on metal surfaces. It is recorded that a new zinc phosphate coating is formed on the metal surface as a rust-proof pigment. During the production process, the concentration of zinc dihydrogen phosphate needs to be effectively controlled during the manufacturing process to achieve the purpose.

　　Zinc oxide for phosphating liquid is a white powder, stable at room temperature, with good covering power and coloring power, insoluble in water and alcohol, but soluble in acid, alkali, and ammonium salt solutions. It is an amphoteric oxide. Zinc carbonate, produced by absorbing carbon dioxide and water from the air, is white. When heated, it turns yellow, and turns back to white after cooling. The phosphating liquid has stable performance, is clear and transparent after dissolution, and can better protect the metal surface from corrosion, aging, and metal protection.

　　1. Used as a vulcanization activator, reinforcing agent, and colorant for natural rubber, synthetic rubber, and latex. The nano zinc oxide particles are small and have a large specific surface area, which can further improve the physical properties of vulcanized rubber.

　　2. Catalyst and desulfurizer. The high surface activity of nano zinc oxide can improve the selectivity and catalytic efficiency of the catalyst.

　　3. Used as a filler, preservative, and luminescent agent in coatings. In addition to the above properties, the excellent sunscreen ability of nano zinc oxide also has outstanding characteristics in the anti-aging aspect of coatings.

　　4. Solvent used in glass and ceramics. Nano zinc oxide particles are small and highly active, which can reduce the sintering temperature of glass and ceramics. In addition, ceramics glazed with nano zinc oxide are more glossy and have antibacterial, mildew-proof, and deodorizing effects.

　　5. In the electronics industry, it is the main raw material for varistors and the main additive for magneto-optical materials. Varistors using nano zinc oxide not only have a low sintering temperature but also can improve the performance of varistors, such as oil flow capacity and nonlinear coefficient. With the in-depth research on the optical properties of nano zinc oxide, the application of nano zinc oxide in optical devices will make a major breakthrough. In addition, it can also be used as a colorant in the printing and dyeing industry.

　　That's all for the explanation from the editor of the zinc oxide manufacturer for phosphating liquid. Thank you for watching!
