聚乙烯醇感光胶是由重铬酸盐与聚乙烯醇混合配制而成的感光性物质,在工业上已广泛用于金属刻度尺、度盘及精细图案的照相复制。为使带有图案的聚乙烯醇感光胶膜具有一定的抗腐蚀能力,必须对其进行坚膜处理,使感光胶膜转变为抗蚀膜层。这对金属制品在膜层的保护下进行选择性腐蚀和电镀是致关重要的。为提高坚膜质量,增强膜层的抗蚀能力,控制生产过程,有必要对坚膜技术进行探讨。
Polyvinyl alcohol photosensitive rubber is prepared by mixing dichromate and polyvinyl alcohol photosensitive material, has been widely used in the industry for metal scales, dials and fine patterns of photographic reproduction. In order to make the pattern of polyvinyl alcohol photosensitive film has a certain anti-corrosion ability, it must be hardened, the photosensitive film into a resist film. This is the metal products in the film under the protection of selective corrosion and plating is crucial. In order to improve the quality of the hardened film, enhance the corrosion resistance of the film and control the production process, it is necessary to discuss the hardener technology.
