Hydrocarbon liquid saponifying washing technology

Abstract

The invention discloses a hydrocarbon liquid saponifying washing technology. The hydrocarbon liquid saponifying washing technology comprises the steps of vacuum ultrasonic saponifying washing performed at three times, vacuum ultrasonic hydrocarbon washing performed twice, and steam bath washing and drying performed twice, wherein a washing agent in the step of vacuum ultrasonic saponifying washing is a G-100W hydrocarbon saponifying agent; the washing agents in the step of vacuum ultrasonic hydrocarbon washing and the step of steam bath washing and drying are G-100 hydrocarbon washing agents. According to the hydrocarbon liquid saponifying washing technology, the hydrocarbon saponifying agent and the hydrocarbon washing agents are used for washing, so that the effect of washing mineral grease and non-mineral grease on the surface of a workpiece can be improved; the repeating times of each step are controlled, so that the yield of the workpiece washing can be further increased and is up to 99%; meanwhile, the workpiece surface is free from grease, watermark, corrosion and the like; the washing quality is stable; the waste liquid treatment cost is low; the environment protection is realized; and the pollution is avoided.

Description

technical field [0001] The invention relates to the field of workpiece surface cleaning, in particular to a hydrocarbon liquid saponification cleaning process. Background technique [0002] At present, when the workpiece needs to be cleaned with a saponifier, the process of ultrasonic water-based cleaning-ultrasonic water-based rinsing-hot air circulation drying is generally used, and the purpose of cleaning is mainly achieved through the action of surfactants in water-based cleaning. With the improvement of the quality requirements for workpiece cleaning and the enhancement of environmental protection awareness, the current cleaning method can no longer meet the requirements. The main problems are: watermarks, oxidation, product corrosion and other undesirable phenomena are prone to appear on the surface of the product after cleaning. At the same time, after cleaning The defect rate is as high as 8%-15%, and the water-based cleaning is easy to generate waste water, which in...
