Surface anti-rust treatment method of filter shell

Steel filter shell surface anti-rust treatment method: usually divided into process anti-rust, process anti-rust and final anti-rust three methods and requirements.  The anti-rust treatment between processes generally uses water-based anti-rust, dehydration and anti-rust methods, anti-rust time is short, can meet the requirements of anti-rust between processes. Process anti-rust treatment has passivation anti-rust, phosphating anti-rust, dehydration anti-rust oil, etc., is due to different process requirements and different. The final anti-rust treatment is mainly oily anti-rust. Because anti-rust grease is not easy to evaporate, so it has a longer anti-rust time.

China's iron and steel anti-rust process development is still in the primary stage, people's awareness of anti-rust or anti-rust methods lack of understanding, the use of anti-rust technology and products are still some traditional concepts. With the rapid development of industrial technology in China, the problem of anti-rust has gradually become the theme of concern, Phosphating products, passivation products, blackening products, water-based anti-rust agent, dewatering anti-rust oil, hard film antirust agent and cutting anti-rust liquid and other products. Scope of application: applicable to machining, grinding, heat treatment, electrolytic processing, hair black orchid treatment and water-based cleaning of a variety of metals or equipment after cleaning dehydration and rust prevention, process rust prevention, process anti-rust and long-term storage of anti-rust.

The above is the common steel filter shell surface anti-rust treatment method introduced.

Filter Shell products in the tensile cold extrusion process I plant has a unique processing means, the use of innovative technology to solve technical problems, especially stainless steel ultra-long deep drawing shell, multi-process rectangular filter drawing deep shell, to overcome the difficulties that other manufacturers can not overcome. To reach the world's advanced level, domestic for electronics, military,. Filter housing power shell by material to divide, can be divided into metal and non-metallic. Metal is divided into copper shell, aluminum shell, steel shell, etc., non-metallic mostly plastic shell.
In terms of performance, the thermal resistance of the metal shell is very low, the temperature rise is also low, in addition, the metal shielding is better, for EMI suppression is also very good. In general, the performance of the metal shell is a win over non-Metal partsThe housing body. Therefore, most of the domestic power of the module power supply are used metal shell. Early because of the high profit of the module power supply, the industry with more copper shell, but with the module power supply profits fell to a small profit, the domestic large number of manufacturers will shell change to aluminum shell, individual manufacturers replaced with steel shell, in order to reduce costs, this can not be said to be a no NAI. But aluminum shells also have advantages, light weight, easy molding, can be directly surge or aluminum oxidation, eliminating the trouble of early copper shells need to spray paint.
