Description

A new type of stainless steel surface polishing process

technical field

The invention relates to the technical field of stainless steel processing, and more particularly, to a novel stainless steel surface polishing process.

Background technique

Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel that is resistant to weak corrosive media such as air, steam, and water or has stainless steel is called stainless steel. The steel grades are called acid-resistant steel, and their corrosion resistance is different due to the difference in chemical composition of the two. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless. The word "stainless steel" Not just one type of stainless steel, but more than one hundred industrial stainless steels, each developed with good performance in its specific application area, the key to success is to first understand the purpose, and then determine The correct steel grades are usually only six types related to building construction applications. They all contain 17 to 22% of chromium. The better steel grades also contain nickel. Adding molybdenum can further improve atmospheric corrosion, especially the resistance to corrosion. Corrosion in chloride-containing atmospheres.

Stainless steel is widely used because of its high corrosion resistance and decorative properties, especially in medical appliances, food industry appliances, tableware, kitchen appliances, etc. The surface of the utensils should not be accompanied by substances that are toxic to the human body. Therefore, the surface treatment requirements for the production of such utensils are to completely remove the harmful substances on the surface. The materials required for stainless steel polishing generally include: "polishing wax, hemp wheel, nylon wheel, cloth wheel, wind wheel, wire cloth wheel" and so on.

At present, the cloth wheel is used the most in the fine polishing of the stainless steel surface, but in the actual use of the cloth wheel to polish the stainless steel surface, the phenomenon of debris flying is prone to occur, especially during the fine polishing, the metal debris generated by friction The particle size of the chips is small, so the dispersion range is wider. On the one hand, it is easy to cause damage to the respiratory tract of the human body, and on the other hand, it is difficult to collect metal chips, which reduces the utilization rate of stainless steel.
