Photo sensitive aluminum CTP plate
The production process of the photo sensitive aluminum CTP plate base is mainly studied for the grit treatment and anodizing treatment involved. When the grit treatment, the surface roughening method, the concentration of hydrochloric acid, the temperature of the electrolyte and other factors are investigated. The influence on the effect of sand meshing treatment is obtained, and the appropriate process conditions are obtained. The concentration of hydrochloric acid is 8-10 g/L, and the temperature of the electrolyte is 30-60℃. During anodizing, the concentration of sulfuric acid, the temperature of the Oxidation time and the influence of impurities in the oxidizing solution on the effect of anodic oxidation, to obtain suitable process conditions, the sulfuric acid concentration range is 15%-30%, the oxidation solution temperature range is 25-30℃, and the oxidation time range is 40-60s. The concentration of aluminum ion in the liquid ranges from 0.5% to 5%. ...
