Problems solved by technology

[0006] But at the same time, because of the strong oxidation activity of vaporized hydrogen peroxide, it is quite corrosive to the workshop of the pharmaceutical workshop. At present, there is no convenient, quick and reasonable value for the anti-VHP oxidation ability of color-coated plates on the market. The popularized test method, so this application aims to propose a method for testing the anti-VHP oxidation ability of color-coated plates for this market gap

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0021] This case provides two test methods, one is the equivalent simulation test, which is mainly to test the VHP oxidation resistance of the color-coated plate by simulating an environment with the same corrosion capacity as vaporized hydrogen peroxide; the other is the real simulation test, which is about to The real pharmaceutical workshop is scaled down to truly imitate the VHP environment during the sterilization of the pharmaceutical workshop. It should be noted that color-coated panels are composed of substrates and organically modified coatings, because these two methods are only the most sensitive and accurate for testing color-coated panels composed of substrates and organically modified coatings.

[0022] The equivalent simulation test includes the following steps:

Abstract

The invention discloses a method for testing resistance of a color-coated sheet to VHP oxidization. According to the method, the color-coated sheet is placed in a hydrogen peroxide atmosphere for a period of time by virtue of an equivalent simulation test and a real simulation test, whether the surface of the color-coated sheet has pulverization, bubble formation or color change or not is observed, and thus whether the color-coated sheet has the capability of resisting VHP oxidization or not is judged. The invention provides two test methods; one method is the equivalent simulation test and the other method is the real simulation test; the two test methods are simple to operate, low in detection cost, and intuitive and accurate in measurement result of the resistance to VHP oxidization. The method for testing resistance of the color-coated sheet to VHP oxidization is especially suitable for small and medium steel processing enterprises and worth to popularize.

Description

technical field [0001] The invention relates to a method for testing chemical corrosion resistance, in particular to a method for testing the anti-VHP oxidation ability of a color-coated plate. Background technique [0002] Color-coated steel plate, also known as color-coated steel plate, is a composite material, mainly composed of substrate and coating, which has the advantages of both steel plate and organic material. Good decoration, corrosion resistance, beautiful appearance and other advantages of the material have achieved good effects such as replacing wood with steel, efficient construction, and energy saving, so it has become a new type of decoration in the construction industry, shipbuilding industry, furniture industry, vehicle manufacturing industry, and electrical industry. Material. At present, color-coated steel sheets are mainly made of cold-rolled steel sheets, electro-galvanized steel sheets or hot-dip steel sheets as substrates, after surface degreasing, ...
