Background
The repair adhesive is an indispensable important material in the chemical milling (hereinafter referred to as chemical milling) process, and the construction of the chemical milling protective coating comprises various modes such as brushing, dipping, roller coating, airless spraying and the like. Because part of the parts or part of the parts are in a curved surface or a radian shape or due to the influence of factors such as impurity particles in the environment, no matter which construction mode is adopted, after the chemical milling protective coating is naturally dried and formed into a film, the defects of pinholes, sand holes, insufficient coating thickness, uneven thickness and the like can be detected by using a 3-8 kV direct-current voltage electric spark leak detector. The coating defects caused by airless spraying may be more. The 'leakage' generated at the defect can seriously affect the quality of the chemical milling and even cause the rejection of the part. Sometimes, the damaged area is larger or the defect is just at the carving position, the repair glue is required to be capable of realizing independent chemical milling, in addition, in order to shorten the working time and ensure the processing progress, the quick-drying repair glue capable of being chemically milled is used for repairing and coating the position with the defect, the defect is eliminated, and the effect of ensuring the chemical milling quality is very obvious.
