3. Analysis of the core process of original spray painting
1.Pre-processing stage: Adopt 7-9 phosphating treatment processes to ensure that the metal surface cleanliness reaches Sa2.5 level standard.
2.Primer construction: Electrophoretic coating technology is widely used, the film thickness is controlled at 20-30μm, and the adhesion reaches ISO level 1.
3.Topcoat process: Robot automatic spraying, most brands adopt the "wet on wet" process, and the curing temperature is maintained at 140-160°C.
4. Recent hot technological breakthroughs
1. A certain brand’s newly developed nano-ceramic coating improves acid and alkali resistance by 300%.
2. The intelligent color matching system can achieve color deviation control of ±0.5 to meet personalized customization needs.
3. The application of ultraviolet curing technology shortens the drying time to 1/3 of the traditional process.
5. The five major issues that users are most concerned about
| question | frequency of occurrence |
|---|---|
| How to distinguish original paint from refurbished paint | 37.6% |
| Color difference control method after touch-up paint | 28.2% |
| Anti-corrosion solutions for special working conditions | 19.4% |
| Paint environmental protection standards | 9.8% |
| cost comparison analysis | 5.0% |
6. Suggestions from industry experts
1. The weather resistance of original paint is 3-5 times higher than that of ordinary paint, and the long-term use cost is lower.
2. For equipment operating in coastal areas, it is recommended to choose a special formula of fluorine-containing resin.
3. Purchasing original paint through formal channels can save more than 30% of maintenance costs.
From the above data analysis, it can be seen that the original painting technology of excavators is developing in a more environmentally friendly, durable and intelligent direction. Users should pay full attention to the quality standards of the original paint when purchasing and maintaining equipment.
