Architectural aluminum is a kind of decorative structural material. In order to improve its decorative effect, enhance its anti-corrosion performance and prolong its service life, it must be surface-treated except in some cases. Therefore, surface treatment has become an indispensable and extremely important process for the production of architectural aluminum profiles. There are many methods for surface treatment, and corresponding surface treatment methods can be used according to the different uses of the materials. The commonly used commercial surface treatment methods are: anodizing coloring method, electrostatic powder spraying method, fluorocarbon spraying method, electrophoretic painting method, chemical coloring method, watermarking treatment method, and the like. China's construction aluminum extrusion companies have their own surface treatment production lines in addition to a few plants. There are eight specialized aluminum surface treatment companies in China, all in Guangdong Province. Test tubes, Pipette guns, Centrifuge Tubes, etc. in the laboratory need to be organized. Therefore, there is a need for laboratory table top racks that are easy to clean, store, and transport. laboratory rack plastic,rack for laboratory,storage rack for laboratory Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yonyue.com
