Chinalco Shandong enterprises step into the field of aluminum surface treatment

Recently, after more than two years of in-depth research and hundreds of experiments, Chinalco Shandong Enterprise Aluminum Processing Factory successfully solved the problem of low yield of aluminum color extinction electrophoresis coloring products, and entered the most advanced aluminum surface deep processing technology field in China. .

“Shan Aluminum No.1” is a key research and development project established by the aluminum processing plant of the company in 2008 in order to develop new technology and open up new markets – aluminum profile color extinction electrophoresis process. The project was established in the same year by Chinalco and was tested and produced in the surface treatment workshop of the aluminum processing plant. It is a surface treatment process integrating electrophoresis coloring and painting. Compared with the surface treatment processes of domestic aluminum profiles such as single tin salt, single nickel salt and nickel tin composite salt, it greatly improves labor efficiency and fills the domestic market. blank. In August 2009, under the efforts of many parties, the trial production of “Shan Aluminum No. 1” was successful, and large-scale production began at the same time. However, through production, the yield of “Shan Aluminum No.1” was only 80.6%. Compared with other types of electrophoretic coloring products, the yield was significantly lower. The QC team of the surface treatment workshop of the aluminum processing plant successfully solved most of the problems in the process through in-depth research, technical training, revision of process parameters, development of corresponding process inspection standards, and regular technical competition. Has reached 91.2%. Its successful research and development indicates that the company has stepped into the most advanced aluminum surface treatment technology in the country, and has reached the quality standards of color extinction electrophoresis products in Japan and Germany.
