Description

Detection method of spraying equipment Technical Field The application relates to the technical field of copper foil manufacturing, in particular to a detection method of spraying equipment. Background The electrolytic copper foil is widely applied to industries such as new energy batteries, 5G communication and the like due to the comprehensive advantages of excellent conductivity, abundant resources, easiness in processing, low cost and the like. In recent years, due to the increasing environmental pollution and energy crisis, the development and use of new energy are particularly important, the electrolytic copper foil production enterprises have also been unprecedented, and the demands of the market for electrolytic copper foil are also increasing. In the related art, the surface treatment of the copper foil is required in the production process of the electrolytic copper foil. In the surface treatment process, the spraying and pickling of the copper sulfate pickling solution are required to be carried out on two opposite surfaces of the copper foil in the thickness direction through the spraying pipe on the spraying equipment, and as the copper sulfate solution is easy to crystallize, the spraying effect on the surface of the copper foil corresponding to the position of the spraying hole of the crystallization is less compared with that of other places, so that the spraying on the surface of the copper foil is uneven, and therefore, the spraying equipment is required to be stopped for checking after one or more copper foils are pickled, so that the blocking condition of the spraying pipe is detected.
