Problems solved by technology
[0005] At present, domestic resources and environmental problems are very serious. Heavy-duty printing methods such as zinc plate and copper plate are gradually being eliminated, while the new green and environmentally friendly magnesium plate-making technology is still immature. Research and promote the production process and corresponding production equipment of magnesium alloy etching plate is an urgent task

Embodiment 1
[0058] This embodiment relates to a production method of a pre-coated magnesium alloy etching plate with a specification of 2×610×914mm, which specifically includes the following steps:
[0059] AZ31B magnesium alloy rolling strip with a thickness of 2.3-2.5mm is selected, and its main elements Al, Zn, Mn, and Ca are detected to be within a reasonable range. Cut the strip to the required width and length, with an error of ±3mm;
[0060] Stack the cut magnesium alloy plates together and put them into a box-type aging furnace, and place a heavy metal block on it to achieve the effect of applying uniform force. cool down;
[0061] Sand the aged magnesium alloy plate to 2.10-2.15 mm with an 80-mesh sander, and then sand both sides of the magnesium plate to 2.05-2.08 mm with a 240-mesh sander; send it directly after sanding Cleaning and drying by human washing and drying machine, the drying temperature is set at 180°C; after drying, place the magnesium plate upright to dry for 4 ...

Description
technical field [0001] The invention relates to a production method and a production device of a pre-coated photosensitive rubber magnesium plate, which belong to the field of non-ferrous metal materials and printing plate making. Background technique [0002] Pre-coated photosensitive glue magnesium plate is also called magnesium plate. At present, there is a wide demand for magnesium plates in the printing field, and the demand is increasing rapidly. In fact, as early as 40 years ago, magnesium alloy plates began to be widely used in the printing field, mainly concentrated in European and American countries. Domestically, copper plates and zinc plates have always been the main ones. The price of magnesium plate remains high again. However, copper plates and zinc plates are very serious to the damage to the environment. At the same time, they are not as good as magnesium plates in all aspects. Therefore, with the advancement of domestic technology, magnesium plates have g...
