Problems solved by technology

However, the traditional coating process often requires the use of hexavalent chromium, and hexavalent chromium is a highly polluting heavy metal material. The continuous accumulation in the environment will cause cancer in the exposed population and has a persistent danger. Therefore, it seriously affects people's physical and mental health. ; Moreover, the traditional coating process still has the disadvantages of high energy consumption, complicated process, and high production cost.

Abstract

The invention relates to a vacuum colorful coating technology which comprises the following steps: 1) preprocessing a to-be-plated workpiece; 2) wiping away water from the plated workpiece, racking the plated workpiece and putting into an oven for drying; 3) putting the plated workpiece into a vacuum furnace; 4) exhausting, discharging and automatically opening a door; 5) quickly testing, adding clean water and 20% sulfuric acid and testing LBD according to the client requirement; 6) checking, packaging, loading and labeling; and 7) discharging from the furnace after putting into the furnace for 50-60 minutes. The vacuum colorful coating technology has the advantages that the vacuum colorful coating technology is simple, the energy consumption is low, the cost is saved, the hexavalent chromium is not adopted in a preparation process and the technology is more environmentally friendly. The plated workpiece prepared according to the method has the characteristics of high hardness and higher abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of coating technology for metal and plastic products, in particular to a vacuum color coating technology. Background technique [0002] With the rapid development of the economy, more and more plated parts are used in production and life, such as metal products, sanitary products, architectural metal products, auto parts products, etc. all use coated parts. However, the traditional coating process often requires the use of hexavalent chromium, and hexavalent chromium is a highly polluting heavy metal material. The continuous accumulation in the environment will cause cancer in the exposed population and has a persistent danger. Therefore, it seriously affects people's physical and mental health. ; Moreover, the traditional coating process also has the disadvantages of high energy consumption, complicated process, and high production cost. Contents of the invention [0003] The present invention aims at th...
