The ubiquitous "three wastes" pollution in China's electroplating industry is serious, and the problem of low corrosion resistance of galvanized technology is expected to be solved. On July 22nd, a new process for anti-corrosion treatment of steel parts—vacuum powder infiltration technology passed technical appraisal in Nantong City, Jiangsu Province.
According to statistics, the annual loss caused by corrosion in the use of steel in China is about 20 billion yuan. Currently, the electroplating zinc, hot dip galvanizing, and thermal spray galvanizing technologies commonly used by more than 10,000 electroplating factories in the country are all in the coating. Accuracy, strength, hardness, "three wastes" emissions, etc. There are serious problems that restrict the development of the metal anti-corrosion industry. In 1999, engineering and technical personnel of Jiangsu Rudong Suyuan Industrial Corporation directed the internationally adopted vacuum infiltration technology and formed a research team to carry out research and development. Based on self-reliance, it developed advanced and practical full-scale zincification processing equipment. , Researchers conducted hundreds of comparative tests on relevant technical parameters in accordance with international standards, and finally mastered the technical points of vacuum powder infiltration. The products have passed the National Machinery Industry Material Performance Testing Technology Center, Shanghai Materials Research Institute, and Shanghai Daily Hardware. The Industrial Institute has detected that all performance indicators are in line with international standards and have been used by a number of users. They reflect well and have begun bulk export.
Relevant experts pointed out that the vacuum infiltration zinc technology developed by the East Suyuan Industrial Corporation is widely used in machinery, chemicals, power, ships, railways, transportation, urban construction, environmental protection, civil and other industries, and the traditional electroplating, hot-dip galvanizing Compared with the zinced layer, it has higher hardness, wear resistance and better anti-corrosion effect, and the workpiece is not deformed. The thickness of the infiltration layer is uniform and controlled. Besides being suitable for large workpieces, it can also be applied strictly. The control of dimensional error components has greatly improved the environment and reached the domestic advanced level.
