The quality control after the coating planning is mainly to use laboratory testing instruments to test various items on the finished sample of the color-coated board, find out the coating defects that cannot be detected by visual inspection, and analyze the causes of them, so that Improve the construction process of the coating and improve the quality of the finished product of the color-coated board.
Another purpose of the quality inspection after the coating is cured is to provide a theoretical basis for quality assurance for color-coated plate users.
The quality inspection items after the coating is cured are mainly based on the 21 performance experiments specified in the national standard GB/T 13448-2006 "Test Methods for Color Coated Steel Sheets and Steel Strips", which includes coating thickness Measurement, specular gloss measurement, color difference measurement, bending test, reverse impact test, pencil hardness test, organic solvent resistance test, abrasion resistance test, scratch resistance test, scratch test, cupping test, boiling water resistance test, acid resistance Alkali test, pollution resistance test, neutral salt spray test, dry heat resistance test, damp heat resistance test, sulfur dioxide damp heat resistance test, xenon lamp accelerated aging test, ultraviolet lamp accelerated aging test, atmospheric exposure test and other items.
