Problems solved by technology

[0002] With the development of the times and the improvement of living standards, people's demand for food packaging cans is also increasing. The traditional iron printing and coating process takes a long time and has low production efficiency, which can no longer meet the needs of the existing market. At the same time, in the existing iron printing process of metal cans, the anti-rust process is poor, and the anti-rust ability is low, which cannot meet the filling and storage requirements of weak acid or weak alkaline beverages. It is urgent to find a way to improve food metal tube printing Efficient iron printing process, in the existing production, UV ultraviolet iron printing has been used, the production is fast, but because all colors are dried at one time, the process is controlled, the quality of the printed iron is poor, and the qualified product rate is low

Embodiment Construction

[0015] The technical solution of the present invention will be described below to facilitate the understanding of those skilled in the art.

[0016] An iron printing process for food metal cans, including the following steps:

[0017] (1) Design and plate making, design the film pattern according to the sample, then stick the film on the ps plate for printing, and expose the ps plate for 110 seconds before developing;

[0018] (2) Substrate treatment, using tinplate thin steel plate, first blow off the sundries on the surface of the steel plate through a high-pressure air gun nozzle, and then rinse the steel plate in an alcohol solution for 10 minutes to remove oil and dust on the surface of the steel plate, and place the steel plate Dry in the air;

[0019] (3) Anti-rust treatment on the surface of the steel plate, apply anti-rust primer on both surfaces of the steel plate, with a dry film amount of 5-6g / m2, and bake at 150℃ for 20 minutes;

[0020] (4) Steel plate background color tr...

Abstract

The invention belongs to the field of metal printing, and more particularly relates to a metal printing technology for a food metal can. The metal printing technology for the food metal can comprises the following steps of designing, plate making, substrate processing, steel-plate surface rust prevention, steel-plate base-color processing, painting of white coating oil, steel-plate lustering, steel-plate shading, and steel-plate detection and package. According to the metal printing technology provided by the technical scheme of the invention, the capabilities of resisting sulfur corrosion, resisting acid etching and resisting rust cession are better; the time of the whole metal printing technology is shorter, and the operation is easier to control.

Description

Technical field [0001] The invention belongs to the field of printing iron, and more specifically relates to a tinplate printing process for making food metal cans. Background technique [0002] With the development of the times and the improvement of living standards, people have more and more demand for food packaging cans. The traditional printing iron coating process takes a long time and the production efficiency is low, which can no longer meet the needs of the existing market. At the same time, in the existing metal cans printing process, the rust prevention process is poor, the rust prevention ability is low, and cannot meet the filling storage requirements with weak acid or weak alkaline beverages. It is urgent to find a way to improve the food metal tube printing Efficient iron printing process. In the existing production, UV ultraviolet printing iron has been adopted, and the production is fast, but because all colors are dried at one time and the process is controlled...
