The influence of surface treatment of 304 stainless steel coil plate on the service life of anti-corrosion layer is about 55%. Therefore, it is necessary to continue to explore and summarize the surface treatment method of seamless steel tube in strict accordance with the provisions of anti-corrosion layer standard on seamless steel tube. 1, 304 stainless steel coil plate cleaning: using organic solvent, solvent to clean up 304 stainless steel plate surface, to be removed, vegetable oil, dust, lubricants, and similar organic compounds, but it can not be remove in the surface of 304 stainless steel plate, rust, scale, such as welding flux, and thus in the anti-corrosion production only as an auxiliary way. 2. Anti-rust treatment for 304 stainless steel coil plate: the key application is to polish and polish the surface layer of 304 stainless steel coil plate with special tools such as steel brush, which can remove loose or warped oxide skin, rust, and weld penetration, etc. The anti-rust treatment of manual tools can achieve Sa2 level, and the anti-rust treatment of special driving tools can achieve Sa3 level. If the surface of 304 stainless steel coil plate sticks to solid zinc ash, the actual effect of anti-rust treatment of special tools is not ideal, it cannot reach the depth of anchor grain specified in the anti-rust regulation of FIBERglass 3, 304 stainless steel coil passivation: generally using organic chemistry and electrolysis two ways to do the passivation solution, steel tube corrosion only choose organic chemical passivation passivation, can remove the oxide, rust, old coating, sometimes can be used as blasting after the solution. Although chemical water treatment can make the surface to achieve a certain degree of cleanliness and surface roughness, but its anchor grain is shallow, and easy to lead to environmental pollution to the natural environment.    |
