The painting of instruments and meters is different from the painting of machinery and electrical products, and also different from the painting of highly decorative automobiles and light industrial products. It has some unique characteristics of painting technology, which are summarized as follows:
1. High decorativeness of instrumentation coating:
The surface decorative coating of instruments and meters requires the use of colorful, soft and gorgeous, bright and plump high-gloss coatings, semi-gloss and flat coatings, and art-type coatings with patterns and patterns, as well as metallic flashes that can produce light-color effects. Painting, satisfied with the high decorative beauty of the instrumentation.
2. Certain corrosion protection performance:
There are various environmental conditions for the use of instruments and meters, and the surface coating needs to have certain corrosion resistance. Such as durability, weather resistance, temperature resistance and chemical bottle corrosion resistance. Protect the surface of the instrument and meter, prolong the service life and expand the application range.
3. Coating embodies functions and functions:
Using the colorful, high-gloss, semi-gloss and other light and color effects of various paints, as well as the embossed and exquisite light and color effects and beautiful patterns of various art paints, the functions and functions of instruments and meters can be reflected and enhanced after painting. .
4. Material and mechanical modeling:
The material surface of instruments and meters before painting should be flat or less defective, so as to reduce scraping and grinding putty. The mechanical shape of instruments and meters should be beautiful and unique, providing conditions for coating to reflect functions and functions.
5. Adopt mechanization and automatic assembly line coating production:
The coating production of the domestic instrument industry has successively adopted professional automatic assembly lines such as electrostatic spraying, electrophoresis, and powder electrostatic spraying. The surface pre-treatment is widely applying the new zinc-calcium film-type phosphating treatment, and the coating of parts such as shells with large batches of coating has realized mechanized and automatic assembly line production, and achieved high technical and economic benefits. This is the future development direction of instrumentation coating.
