2019-06-24

Many friends in the industry know that stainless steel storage tanks need to be polished before they can be used. Small make up today from Dongguan polishing plant Tiantie hardware was informed that there are three main polishing processes commonly used in stainless steel storage tank polishing. 1, stainless steel electrolytic polishing stainless steel electrolytic polishing process is a kind of use of electrolytic chemical reaction changes to make stainless steel parts surface smooth polishing process collectively. The polishing method generally takes the polished workpiece as the anode, the insoluble metal as the cathode, and the two poles are immersed in the electrolytic cell at the same time, and the selective anode dissolution is produced by direct current,

Many friends in the industry know that stainless steel storage tanks need to be polished before they can be used. Small make up today from Dongguan polishing plant Tiantie hardware was informed that there are three main polishing processes commonly used in stainless steel storage tank polishing.

1. Electrolytic polishing of stainless steel

Stainless steel electrolytic polishing process is a kind of use of electrolytic chemical reaction change to make the surface of stainless steel parts smooth polishing process. The polishing method generally takes the polished workpiece as the anode, the insoluble metal as the cathode, the two poles are immersed in the electrolytic cell at the same time, and the selective anode dissolution is produced by direct current, and the surface of the workpiece is gradually flattened, so as to achieve the effect of increasing the surface brightness of the workpiece. Stainless steel electrolytic polishing process generally goes through degreasing, rust removal, electrolytic polishing, neutralization, passivation, packaging and other processes, and goes through a water washing process between degreasing, rust removal, electrolytic polishing, neutralization and passivation processes. Stainless steel electrolytic polishing generally has strict requirements for electrolytic polishing liquid. The electrolytic polishing liquid used for stainless steel of different materials is also different. The same polishing liquid is applied to different stainless steel materials, and the polishing effect is also different.

2. Mechanical polishing

Mechanical polishing is a polishing method to obtain a smooth surface by cutting and plastic deformation of the surface of the material to remove the polished convex part. Generally, auxiliary materials such as oilstone strips, wool wheels, sandpaper and the like are used to carry out polishing work. The application of mechanical polishing in the polishing process of stainless steel molds is generally to increase the cleanliness and hygiene of stainless steel.

3. Chemical polishing

Chemical polishing is a method of eliminating wear marks and etching leveling by selective dissolution of uneven areas on the surface of the sample by chemical etching of chemical reagents. The chemical polishing equipment is simple, capable of handling thin tubes, parts with deep holes and complex shapes, and has high production efficiency. Chemical polishing is also the most commonly used polishing method in stainless steel mold polishing process. It often has a good polishing effect on steel parts, especially low carbon steel.
