A breakthrough was achieved in the treatment-free printing plate base aluminum alloy plate developed by China Aluminum Materials Institute and China Aluminum Ruimin

Recently, the technical achievements of the processing-free printing plate-based aluminum plate developed by the China Aluminum Materials Institute and Chinalco Ruimin have been evaluated by experts in the non-ferrous metal industry. The overall technology has reached the international advanced level. Among them, the aluminum profile and anodized quality indicators Reach the international leading level.

In order to break through the technological blockade, the China Aluminum Materials Institute and Chinalco Ruimin have carried out a technological breakthrough in the treatment of aluminum alloy sheets for the base of printing plates. After many process verifications in the pilot workshop of China Aluminum Materials Institute, the fundamental reason for the deformation ability and high resolution of the printing plate base was found, and the "alloy composition-preparation process-metal structure-mechanical properties-electrolysis and anodized surface Based on the relationship between morphology and defects, a new type of aluminum alloy plate and strip alloy composition and key preparation technology have been developed, and aluminum alloy plate and strip for processing-free printing plate base have been successfully prepared in Chinalco Ruimin. All performance indicators exceed similar foreign products.

Processing-free printing plate base refers to the printing plate base that uses computer to make plates directly and scan and image. Compared with ordinary printing plate bases, it can save steps such as preheating, developing, gluing and baking. It is environmentally friendly and has high deformability. , High resolution, high printing resistance and other advantages, there is a lot of room for development. At present, the non-disposal printing plate base aluminum material is monopolized by foreign companies, and my country is subject to patent and technology blockade.

The processing-free printing plate base aluminum alloy sheet developed by China Aluminum Materials Institute and Chinalco Ruimin has filled the domestic gap and realized import substitution. It has a domestic market share of 90%. Some products are exported to Japan and Europe, strengthening Chinalco The Group's core competitiveness in the field of printing plate bases has strengthened the leading and supporting role of technology.
