This paper relates to an electropolishing apparatus for electropolishing the inner surface of a tank. In particular, a large tank that stores ultrapure gas for supplying ultrapure gas and contents to key components of equipment for producing semiconductors, Food, beverage storage tanks, chemical storage tanks, pharmaceutical storage tanks, liquor storage tanks, various stirring tanks, various supply tanks. Most of the tanks can be obtained by electrolytic polishing to obtain the inner surface of various dairy storage tanks. The surface of the material with high viscosity by improving the purity by preventing the elution of impurities and harmful substances such as iron, nickel, chromium and tallow contained in the stainless steel structure used in manufacturing Sanitary products can be produced by preventing attachment, and productivity can be improved by preventing corrosion. By the re-electropolishing times the inner surface of the tank for reuse relates to an electrolytic polishing apparatus.

In general, large tanks that store ultra-pure gas made of stainless steel, food, beverage storage tanks, chemical storage tanks, pharmaceutical storage tanks, liquor storage tanks, various stirring tanks, various supply tanks, various dairy oil storage tanks, etc. The inner surface of large tanks should have the same surface roughness as mirrors.

That is, when the surface roughness of the inner surface of the tank falls, various impurities and harmful substances are attached to the inner surface of the tank, and microorganisms can breed.

As described above, when microorganisms are attached to the tank and start breeding, various gases or medicines stored in the tank, and liquor or dairy oil also contaminate food, drink, and the like, and thus cannot produce sanitary products.

In addition, since the inner surface of the tank is easily corroded due to the propagation of microorganisms as described above, the surface roughness of the inner surface of the tank must be mirrored (mirrorized).

Conventionally, the operation of polishing the inner surface of the tank with high precision has been dependent on the manual labor of the operator.

That is, the worker was to grind the inner surface of the tank by a hand grinder to enter the tank and grind the inner surface of the tank.

As described above, as the polishing operation of the inner surface of the tank is performed by the operator's hand, it becomes very difficult to obtain surface roughness and smoothness such as a mirror.

Due to the lack of ideal surface roughness and smoothness as described above, impurities and debris are adhered to the inner surface of the tank, and the growth of microorganisms is activated. It will contaminate beverages and make it impossible to produce hygienic products.

In addition, since the inner surface of the tank is easily corroded due to the growth of the microorganisms as described above, there was a problem in that the tanks had to be replaced with a new tank within a short time after the tanks were installed.

In particular, when the gas supplied from the tank is supplied to the semiconductor line, a core part of the semiconductor is manufactured, and there is a problem that the defect rate of the semiconductor fabrication is very high due to the frequent supply of mixed gas and impurities. there was.

The purpose of this article to solve and complement these conventional problems,

It can improve the purity by preventing the dissolution of impurities such as impurities and harmful substances and at the same time mirror the surface roughness of the inner surface of the tank to prevent the surface adhesion of substances with high viscosity to produce hygienic products and prevent corrosion and improve productivity. Also, even when the tank is replaced, the used tank can be reused by re-electropolishing and re-polishing several times. It provides a purpose to increase.
