Problems solved by technology

[0003] For containers (usually barrel-shaped) used to hold corrosive solutions, not only have high corrosion resistance requirements for the container itself, but also have certain physical performance requirements for the container cover. At present, chrome covers are mostly used, but In some extreme use environments, such as high temperature environments, or under conditions of high corrosion intensity, the physical properties of chromium alone cannot fully meet the use conditions. Once the chromium cover is damaged, the corrosive solution in the container will leak or volatilize Therefore, it is necessary to strengthen the physical properties of the chrome cover

Abstract

The invention discloses a chrome cover surface film coating process, and relates to the technical field of metal sheet surface treatment. The chrome cover surface film coating process comprises the following steps that S1, the top surface of a chrome cover is coated with a film through coating, the film coating thickness is 5 g / m<2>-6 g / m<2>, then the chrome cover is baked through an oven A by means of a conveyor, the baking temperature is 180 DEG C-185 DEG C, and the baking time is 1 min-2 min; S2, the chrome cover is taken out to be naturally cooled, the bottom surface of the chrome cover is coated with a film through coating, the film coating thickness is 5 g / m<2>-6 g / m<2>2, then the chrome cover is baked through an oven B by means of the conveyor, the baking temperature is 180 DEG C-183 DEG C, and the baking time is 1 min-2 min; S3, the chrome cover is taken out to be naturally cooled, the bottom surface of the chrome cover is coated with a film through coating, the film coating thickness is 7 g / m<2>-8 g / m<2>, then the chrome cover is baked through an oven C by means of the conveyor, the baking temperature is 195 DEG C-200 DEG C, and the baking time is 2 min-3 min; and finally the chrome cover is taken out to be naturally cooled. According to the chrome cover surface film coating process, the two surfaces of the chrome cover are coated with the films according to the process, and the excellent performance of high temperature resistance, corrosion resistance and the like can be improved.

Description

technical field [0001] The invention relates to the technical field of surface treatment of metal plates, in particular to a coating process for the surface of a chrome cover. Background technique [0002] Chromium has high corrosion resistance. In the air, even in red hot state, it oxidizes very slowly, and it is insoluble in water. It can be plated on the metal for protection. Today, the chrome plating process can be said to be a "traditional" metal plating technology. The chrome plating layer has high hardness, wear resistance, corrosion resistance and can keep the surface bright for a long time. The process is relatively simple and the cost is low. For a long time, in addition to being used as a decorative coating, chrome plating is also widely used as a wear-resistant and corrosion-resistant coating for mechanical parts, and is often used to repair damaged parts. As far as the current classification is concerned, there are two types of chrome plating, one is decorative...
