Analysis of several factors affecting the quality of printed color coated panels

The factors affecting the quality of printed color coated board are mainly reflected in the poor quality of substrate, change of surface tension of coating, improper pre-treatment, curing defects, coating defects and scratches, etc. Printed color coated boards produced from cold rolled substrates have limited corrosion resistance, as any slight abrasion of the surface coating will quickly appear as red rust affecting its use. The color coating of this substrate can be used to make the internal parts of household appliances, or for temporary isolation fences that are not high, so the quality of the printed color coated board depends mainly on the choice of the substrate, the substrate can be used cold-rolled substrate, electro-galvanized substrate and hot-dip galvanized substrate, aluminum-zinc coated steel plate, should be used according to the different uses of the material with suitable mechanical properties.

Printed color coated board quality is good or bad in addition to the quality of raw materials has a great relationship with the production of products and process technology has a great relationship, we want to print color coated board quality under the premise of ensuring the same raw materials to ensure that the production process technology is first-class.

The printed color coated board with galvanized zinc substrate is protected by zinc layer and has higher corrosion resistance than the color coated board with cold rolled substrate. In the production of products and components that require corrosion resistance, the use of electro-galvanized steel plate as the substrate of the color coated plate can be considered. Such as the internal and external components of air conditioners, washing machines or refrigerator shells; walls for internal decoration, furniture, lighting equipment, signage, etc. We all know that color coated galvanized sheet is in various colors, the coloring problem and how to control the color coated galvanized sheet without color difference are the problems that our manufacturers need to overcome and the key to ensure product quality.

The process uses the spray method to apply chemicals, except for the third step, which uses the dipping method. The post-treatment process generally contains chromium, which not only removes excess residue from the surface of the coil, but also creates a layer of chromium-containing compounds on the surface, improving the corrosion resistance of the coil. In the application of aluminum coil material, the film weight of 30 to 6 5 m g / m Z . Most of the post-treatments for this process also use chromium-containing compounds.

The choice of substrate is different for different products. It is important to choose the right substrate to produce a good product.
