Abstract

The invention relates to the technical field of electroplating pretreatment, in particular to a process for carrying out vacuum cleaning, oil removal and wax removal by a modified hydrocarbon cleaner. The process comprises degassing ultrasonic cleaning, vacuum cleaning, vacuum steam flushing, vacuum drying and the like. A plurality of flows are carried out in the vacuum environment with a certain vacuum degree and are matched with a degassing ultrasonic cleaning and vacuum cleaning technology and the modified hydrocarbon cleaner. For the cleaning process, in the whole process, harmful substances of halogen and the like, such as trichloroethylene, methylene chloride, tetrachloroethylene and the like, cannot be used and additional drying equipment is not required. Particularly, the process has excellent cleaning effect on irregular articles with blind holes, joints, gaps, cracks and the like. Meanwhile, the defects of oil removal and wax removal of the conventional process are overcome.

Description

technical field [0001] The invention relates to the technical field of electroplating pretreatment, in particular to a modified hydrocarbon cleaning agent vacuum cleaning degreasing and waxing process. Background technique [0002] In the surface pretreatment process of the electroplating industry, most of them currently use the cleaning process of trichlorethylene and water-based cleaning agent to remove oil and wax. Trichlorethylene is widely used in the electroplating industry because of its strong dissolving ability, good wax removal effect, non-combustibility, and fast volatilization. However, trichlorethylene is relatively toxic, which can easily cause occupational diseases and even cause death of workers. Some developed countries in Europe and the United States have banned the application of trichlorethylene in the cleaning industry. With the enhancement of people's awareness of environmental protection, some highly toxic cleaning agents and ODS cleaning agents will ...
