Abstract

The invention relates to the technical field of gravure plate making, in particular to a copper chloride corrosion device and method for a printing roller. The copper chloride corrosion device comprises a corrosive liquid groove used for containing corrosive liquid, a detection sensor used for detecting the concentration of raw materials in the corrosive liquid, and an automatic sample adding device used for automatically adding the raw materials. The detection sensor is electrically connected with the automatic sample adding device. According to the corrosion device, emission of waste water can be reduced, labor efficiency of workers is lowered, and the corrosion quality is obviously improved. The corrosion method is simple in technology and convenient to operate and control; the problems that corrosion is uneven, lateral corrosion is severe and corrosion is difficult to control can be solved, wherein the problems are likely to happen in the corrosion process; and in addition, stability of the corrosive liquid can be ensured.

Description

technical field [0001] The invention relates to the technical field of gravure plate making, in particular to a copper chloride corrosion device and corrosion method for a plate roller. Background technique [0002] At present, copper roller plate making technology mainly includes two production methods: electronic engraving and laser engraving. Laser engraving has been widely used due to its arbitrary mesh depth, but ferric chloride is generally used for etching, but due to its serious pollution and Severe reaction There are serious side erosions in production, resulting in serious differences in the thickness of horizontal and vertical strokes, serious color differences in large-area layouts, severe uneven corrosion of local patterns, and great difficulty in manual control. This requires the use of a slow-response etching. solution, copper chloride is used, but due to the consumption of cu in the etching solution in the reaction 2+ The problem makes the reaction stability...
