How to maintain the chassis cabinet shell

The chassis cabinet shell has good usability. As a protective facility, it is easy to operate, install and maintain, making the operator safe. At the same time, the chassis cabinet shell has strong anti-sunlight performance, is not easy to conduct heat, and reduces the working temperature of the internal equipment; anti-freeze, no rust, no maintenance, long life; good performance, no condensation caused by cold and hot changes; good flame retardant performance; good mechanical properties, good impact resistance.

As an indispensable operating device in the equipment, the chassis cabinet shell can make the equipment stable and avoid equipment damage caused by the environment. In recent years, the chassis cabinet shell has been everywhere in our lives, bringing convenience to life.

But there is one thing to note. Although the chassis cabinet shell is made of cold-rolled steel plate, long-term use will also damage the product. We need to protect it and let it run well. The significant improvement of the corrosion resistance of the chassis cabinet shell depends on the chromium content, but when the chromium content is high, although the corrosion resistance can still be improved, the effect is not obvious. The reason is that when the steel is alloyed with chromium, the surface oxide is reduced, and the type is changed to a surface oxide similar to that formed on pure chromium metal. This tightly adhered chromium-rich oxide protects the surface and prevents further oxidation. And this oxide layer is so thin that you can see the natural sheen of the steel surface through it, giving the chassis enclosure its surface. If the surface layer is damaged, the exposed steel surface will react with the metal surface. The atmosphere repairs itself and reforms this oxide "passivation film" to continue to protect the chassis enclosure.
