During the process of sheet metal processing, metals are not allowed to be oxidized. In addition, the thickness of the metal is required to exceed the thickness of the treated goods; but in actual operation, there is hardly any metal that has not been oxidized, so what do you need to do with the oxidized metal?
In the process of hardware processing, the strong corrosion method is not removed by selecting hydrofluoric acid and nitric acid. However, this method is gradually abandoned by sheet metal processing industry due to its environmental pollution, harmful to human body, high corrosiveness and high cost. At present, there are two kinds of methods for the treatment of oxide scale in Shenzhen sheet metal processing plant.
1. sandblasting / shot peening: in general, the method of spraying micro glass beads is used to remove the black oxide scale.
2. through chemical method: use a pollution-free pickling and passivation paste and normal temperature harmless inorganic additives cleaning liquid to soak. The purpose of albinism is to achieve the nature of stainless steel. The metal equipment handled by this method seems to be a dull color. This method is more suitable for large and promiscuous goods.
How to reduce the resonance of chassis cabinet during the hardware processing?
The vibration in the working process of the cabinet can be reduced by the method of installing the shock absorber during the process of sheet metal processing. After the shock absorber is installed, there is basically no resonance expansion in the category of 10 to 2000Hz. Although there are irregular peaks around 200Hz, the cabinet has a resonance expansion, but the time category is very short and the rate of transmission decreases faster, so the effect on the cabinet is not very large. In addition, the chassis of the cabinet should be tested on the surface of the chassis, and whether the connecting place presents a loose appearance. If this phenomenon occurs, we should be imprisoned in time.
