Problems solved by technology

However, the process is unstable, and the corrosion resistance of the metal surface is poor, especially on the inner walls of various metal furniture. At the same time, the adhesion of the paint film layer after painting is not as good as that of traditional phosphating treatment, which affects product quality. The furniture factory caused a claim after using it, so the existing two traditional crafts can no longer meet the corresponding requirements, and each metal furniture factory has always hoped to find a better method to obtain better results

Embodiment Construction

[0023] The surface self-swimming process of various metal furniture includes the following steps: hang the workpiece→spray pre-degreasing→soaking cleaning→soaking degreasing→spray cleaning→soaking ultrasonic cleaning→self-swimming in the swimming pool→spray water cleaning→baking →Surface electrostatic powder spraying→baking and solidification→cooling→workpiece blanking; Among them, in the self-swimming tank self-swimming process, the raw materials of the self-swimming liquid in the self-swimming tank are all water-based materials, including polymer acrylic acid, solid powder, Stabilizers and defoamers, when depositing, add automatic deposition chemical reaction materials to the bath, when self-swimming, immerse the workpiece in the self-swimming tank, the chemical reaction materials corrode the surface of the workpiece, and the partially dissolved Fe ions and The solid powder reacts to form a solid powder to precipitate and deposit on the surface of the metal workpiece to form ...

Abstract

The invention discloses an autophoresis technology for surfaces of various metal furniture. The autophoresis technology comprises the following steps of workpiece washing, autophoresis in an autophoresis tank and baking curing. In the process of autophoresis in the autophoresis tank, the composition raw materials of autophoresis liquid in the autophoresis tank are water-based raw materials and comprise acrylic acid, solid powder, a stabilizer and a defoaming agent, during deposition, automatically deposited chemical reaction materials are added into the tank liquid, during autophoresis, workpieces are soaked in the autophoresis tank, the chemical reaction materials corrode the surfaces of the workpieces, wherein part of dissolved Fe ions react with the solid powder, so that the solid powder is separated out and deposits on the surfaces of the metal workpieces to form wet films, and finally, the wet films are fully dried through the baking curing process to form cured films. The surfaces of the various metal furniture treated through the autophoresis technology are good in salt spray test effect, high in rust resistance and good in impact resistance, the service life of the productis greatly prolonged, meanwhile, in the treatment process, the environment friendliness is good, the energy consumption is low, and thus the autophoresis technology is worthy of popularization.

Description

technical field [0001] The invention belongs to a metal surface treatment process, in particular to a self-swimming process on the surface of various metal furniture. Background technique [0002] In the current technology, people have higher and higher requirements for the quality of home furnishing, and the conditions are becoming more and more harsh. They not only require beauty and practicality, but also require environmental protection. For indoor and outdoor metal furniture, the current processing methods are divided into two types. The first is the traditional phosphating treatment. Phosphating is a process of chemical and electrochemical reactions to form a phosphate chemical conversion film. The formed phosphate conversion film is called a phosphating film, which mainly provides protection for the metal surface. To a certain extent Prevent the metal surface from being corroded. It is used as a primer before painting to improve the adhesion and anti-corrosion ability...
