The pretreatment of the electrophoretic coating line mostly adopts the immersion and spraying treatment methods (or the combination of spraying and dipping). Its main purpose is to achieve the purpose of oil removal, degreasing, rust removal, water washing and pure water washing through the chemical liquid (sulfuric acid and nitric acid) in the form of immersion or spraying, and the chemical reaction with the oxide and grease on the surface of the workpiece. Cathodic electrophoresis or anodic electrophoresis is adopted for electrophoresis. Compared with anodic electrophoresis, cathodic electrophoresis is more mature in technology, and the adhesion and corrosion resistance of paint film after electrophoresis are stronger than that of anodic electrophoresis. The decorative paint after swimming can be sprayed or decorative paint. The pre-treatment of the conveying system generally adopts self-propelled hoist or stacked conveying equipment, and the transfer line after the pre-treatment generally adopts the ground chain skid, suspended conveying chain, head office hoist and other conveying methods. The specific needs shall be determined according to the workpiece conditions. The main determinants are the size, shape, weight and material of the workpiece.
The painting and coating line is represented by the plastic parts process. Most of the pre-treatment methods are spray treatment (some metal parts are immersed or spray and immersion). The main purpose is to achieve the purpose of oil removal, degreasing, water washing and pure water washing through the chemical liquid (sulfuric acid and nitric acid) and the oxide and grease on the surface of the workpiece by soaking or spraying. The surface coating is decorative paint materials such as anti-corrosion paint, color paint and varnish. In consideration of high-temperature deformation of plastic parts, the film-forming temperature of the paint is generally about 50-80 ℃. The pre-treatment of the conveying system generally adopts light hanging chain, conveyor belt and mesh chain conveying equipment, and the transfer line after the pre-treatment generally adopts ground chain skid, hanging conveyor chain and other conveying methods. The specific needs shall be determined according to the workpiece conditions. The main determinants are the size, shape, weight and material of the workpiece.
It can be divided into air suspension conveying equipment and ground conveying complete equipment
Electrophoresis equipment, tank, chamber, platform, oil removal device, iron dust removal device, silane or phosphating slag removal device, mixing and spraying pipeline system, shaft sealing system, temperature control system, lighting system, air supply
The surface of the workpiece can be cleaned of oxide scale, burr, welding slag and rust, so as to meet the process and surface strengthening requirements of coating roughness
