A new era of spraying: automation, intelligence, the future is here!
Electrostatic powder coating technology has the following advantages:
1. **High deposition rate and powder utilization**: The deposition rate of powder electrostatic spraying is over 80%, and the utilization rate of powder is higher, reaching over 85%, compared to only 30-60% for solvent-based coatings. This means that more powder is effectively deposited on the workpiece during the spraying process, rather than being wasted in the environment.
2. **High economic efficiency**: Powder electrostatic spraying is economically efficient due to the high powder utilization and simplified coating process. It reduces the consumption of labor and materials, shortens the coating cycle, and reduces the accumulation of in-process products.
3. **Excellent coating film properties**: The coating formed by powder electrostatic spraying is thicker and has good mechanical and chemical properties, such as impact resistance, abrasion resistance and corrosion resistance, which are superior to solvent-based coatings.
4. **Environmentally friendly**: The process of powder electrostatic spraying does not contain organic solvents, does not produce solvent vapors, and does not pollute the air, so there is no need for strict environmental protection measures, and there is no problem with the treatment of waste gas emissions.
5. **Energy saving**: Since there is no organic volatiles produced by the powder coating, it avoids waste due to volatilization into the atmosphere, so compared with liquid coating, the energy cost is greatly reduced.
6. **Film uniformity**: a spraying can get a uniform film, no need for repetitive spraying, and no need to play primer, than the same film thickness of the coating operation speed, high efficiency.
7. **Easy to operate**: powder coating process is simple, only pretreatment, powder coating, curing and other processes can be completed, simplifying the traditional means of multi-process spraying, and easy to operate.
8. **Strong adaptability**: Powder coating can be sprayed by electrostatic powder coating method, not subject to the limitations of the shape and size of the workpiece, but also with solvent-based coatings or electrophoretic deposition of coatings for mixed coating use.
9. **High yield**: Before curing, if the workpiece needs to be improved and there is a local leakage of spraying, it can be re-sprayed for the second time until it meets the processing requirements, and the yield is much higher than the traditional painting process.
10. **High reuse rate**: The oversprayed powder can be collected and separated by the powder recovery system in the equipment, and then mixed with the new powder, the recycling rate can reach more than 98%.
11. **Ease of use**: powder coating at room temperature storage stability, do not need to adjust the viscosity with the season, and do not need to be sprayed and placed for a period of time, so that the solvent volatilization and then drying, only heating and baking melt curing, you can form a smooth and bright permanent film, to achieve decorative and corrosion prevention purposes.
In summary, electrostatic powder coating technology has been widely used in many industries due to its advantages of high efficiency, environmental protection, energy saving and easy operation.
