Process method of coating line

Abstract

The invention discloses a process method of a coating line. The process method comprises a fore-treatment process, an electrophoresis process, a pretreatment process, a middle coating process and a finish paint process which are operated in sequence, wherein the fore-treatment process comprises the following steps of pre-washing, degreasing, water washing, surface adjusting, water washing, silanization and pure water washing treatment; the electrophoresis process comprises the following steps of cathode electrophoresis, secondary electrophoresis, ultrafiltration spray washing, ultrafiltrationimmersion washing, the pure water washing, electrophoresis drying, electrophoresis strong cooling, checking and finishing; the pretreatment process comprises the following steps of pasting shielding,spraying PVC, shielding removing, welding seam and gluing, glue drying and glue strong cooling treatment; the middle coating process comprises the following steps of middle coating wiping, middle coating paint spraying, middle coating flash off, middle coating drying, middle coating strong cooling and middle coating grinding treatment; the finish paint process comprises the following steps of finish paint wiping, finish paint spraying, finish paint flash off, finish paint strong cooling, finishing varnish spraying, finishing varnish, finishing varnish washing, finish paint strong cooling and overhauling. According to the method, air and corrosion substances such as water and the like can be prevented from being attached to the surface of an automobile, so that the surface of the automobileis enabled to have an anti-corrosion effect.

Description

technical field [0001] The invention relates to the technical field of automobile painting, in particular to a process method of a painting line. Background technique [0002] The purpose of automobile painting is to make the surface of the automobile (including parts) achieve the effect of anti-corrosion, protection and decoration, and to prevent corrosive substances such as air and water from adhering to the metal sheet, relying on the smoothness of the coating and the color and Gloss gives the car a beautiful appearance, but the car coating process in the prior art is simple, and cannot make the car surface achieve the anti-corrosion effect better. Contents of the invention [0003] Aiming at the above-mentioned problems that the existing automobile coating process cannot achieve the anti-corrosion effect on the automobile surface, it is now aimed to provide a method that can block the corrosive substances such as air and water from adhering to the automobile surface, s...
