Workpiece cleaning method

Abstract

The invention discloses a workpiece cleaning method. The method comprises the steps that work gas is led into a plasma generator, gas in the plasma generator is pumped out, and the gas pressure in theplasma generator is in the preset range; a power source is started, the work gas left in the plasma generator conducts discharge, and plasmas are generated to clean a to-be-cleaned workpiece; and after the preset time, air is led into the plasma generator, and the interior of the plasma generator recovers to the normal pressure. According to the provided workpiece cleaning method, waste water canbe avoided, and environment pollution is reduced.

Description

technical field [0001] The invention relates to the field of workpiece processing, in particular to a workpiece cleaning method. Background technique [0002] Electroplating is a surface treatment process that uses the principle of electrolysis to form a layer of metal or alloy coating on the surface of the workpiece, which is called the electroplating process. Electroplating can protect and decorate the surface of the workpiece and obtain certain special properties, such as wear resistance, corrosion resistance, decoration, and increased hardness. Electroplating is widely used in many fields such as machinery, electronics, aviation, aerospace, military industry, etc., and occupies a very important position in my country's manufacturing industry. According to incomplete statistics, there are currently more than 15,000 electroplating factories in my country, with about 1 million employees in the industry and an annual output value of more than 80 billion yuan. While the ele...

Problems solved by technology

These methods can effectively clean the surface of the workpiece, but these methods still use acid, lye and other substances. Although the amount of use has been reduced, it is still a wet cleaning process fundamentally, and the generation of waste water is inevitable.
