A kind of electrophoresis process and device

Abstract

The invention discloses an electrochromatic swimming process and device, comprising a moving seat, U-shaped frames are fixed on the bottom of both ends of the moving seat, and an L-shaped hanger for hanging products is fixed on the bottom of the U-shaped frame. The bottom of the moving seat is fixed with a pre-detection device used for early detection of the previous reaction pool during electrophoresis of the product, and a storage component is fixed between the two U-shaped frames to prevent the product from dripping after being dipped and stored. The present invention passes the pre-detection The device realizes the detection of the liquid in the previous treatment tank during the electrophoresis processing of the product, and can detect the liquid in the treatment tank through physical examination, so as to avoid the unqualified liquid in the treatment tank from making the coloring effect of the product unstable, reduce the outflow of defective products, and improve the quality of the product In addition, by storing components, after the product is processed in the treatment tank, the residual liquid can flow into the next treatment tank, reducing the infestation of the water body in the treatment tank.

Description

technical field [0001] The invention relates to the technical field of electrophoresis, in particular to an electrophoresis process and device. Background technique [0002] Electrophoresis refers to the movement of charged particles towards the opposite electrode under the action of an electric field, which is called electrophoresis (electrophoresis, EP). The technique of using charged particles to move at different speeds in an electric field to achieve separation is called electrophoresis. [0003] Electrophoretic coatings are widely used in various industries such as automobiles, light industry, construction, furniture, and electrical appliances. Electrophoretic coating is a relatively new coating process at present. It is a water-soluble organic coating with a positive (or negative) charge, which is uniformly dissolved (or dispersed) in an aqueous solution at a relatively dilute concentration. The conductive workpiece (coated object) is used as the anode (or cathode) ...

AI Technical Summary

Problems solved by technology

[0004] In the existing electrophoresis steps, there will be steps such as electrolytic degreasing→water washing→activation→electrophoresis→baking. In each step, the product is hung up and then immersed in each pool for treatment. Each step requires a liquid concentration For example, the water quality requirement for washing is 10us / cm, and the sulfuric acid content is 1% for activation. Therefore, it is necessary to always pay attention to the liquid conditions in each reaction pool. Most of the existing ones are detected by sensors in the pool. When unqualified reaction pools are detected, It will make the coloring effect of the product unstable, but because the sensor is in the reaction pool, when it detects that the liquid in the pool is unqualified, it is impossible to prepare to judge which products, which will cause defective products to flow out, resulting in a low pass rate of good products, while electrophoresis processing At this time, the product will bring the liquid in the previous treatment pool to the next treatment pool, thereby accelerating the unqualified liquid in the treatment pool. For this reason, we propose an electrochromatic swimming process and device
