With the rapid development of modern industry, phosphating technology has been widely applied and greatly developed. Its development trend is mainly reflected in the development of new phosphating agents and the development of various efficient and energy-saving phosphating treatment equipment.
1. Development of new phosphating agents
① Developing towards efficiency. The main focus is on the development of high-efficiency oil and rust removal agents, as well as the development of high-quality phosphating solutions and high-efficiency passivation solutions. These high-efficiency agents have low dosage, low concentration, and high efficiency.
② Developing towards low energy consumption. Mainly, low-temperature and room temperature phosphating agents have been widely used
③ Developing towards low toxicity. Mainly to reduce the pollution of degreasers and surface conditioners, develop nickel free and nitrite free phosphating solutions, and develop chromium free passivation solutions. As is well known, nitrogen and phosphorus are the eutrophic substances that cause water eutrophication and marine red tide. Therefore, developing nitrogen and phosphorus free oil removal agents is very valuable
④ Developing towards a direction that facilitates industrial management. General phosphating agents, no matter how good their performance is, lose their practical value if the technical requirements are too strict, the process conditions are too harsh, and equipment maintenance is too cumbersome. Therefore, developing new low-temperature and room temperature phosphating agents with good production stability, simple operation, stable process, and less phosphating residue has important practical significance.
⑤ Developing towards functionalization. Develop different phosphating agents according to different usage purposes.
2. Development of new phosphating treatment equipment
① Development of high-efficiency automated phosphating treatment equipment. Efficient and convenient phosphate treatment conveying equipment; Computer controlled oil-water separation equipment and phosphating slag removal equipment; The development of an automatic detection system for process parameters and automatic addition of chemicals.
② Development of low energy consumption equipment. Energy conservation and consumption reduction are of great practical significance to various production industries, therefore the development of various energy-saving phosphating treatment equipment has received attention, such as automatic control of heating systems, development of energy-saving heating components, and application of new insulation materials.
In summary, the overall trend in the development of future phosphating technology is the development of high-efficiency and low pollution phosphating agents; Development of high-efficiency and low-energy phosphating treatment equipment.
