In the process of storage shelf rack production, the surface of warehouse racks is sprayed with solid powder coating instead of liquid solvent-based coating. The powder coating is negatively charged by high voltage and is adsorbed on the surface of the grounded coated workpiece by electrostatic attraction. The coating film is obtained after heating and melting (or curing). Electrostatic spraying is a new process, so what are the benefits of electrostatic spraying on storage shelf racks?
There are many advantages of electrostatic spray molding for storage shelf racks, which can be summarized as follows:
1. No need for diluents, construction has no pollution to the environment and is non-toxic to the human body;
2. The coating has excellent appearance quality, strong adhesion, and mechanical strength;
3. Short curing time for spraying construction;
4. The corrosion resistance and wear resistance of the coating are much higher;
5. No primer is required;
6. Simple construction with low technical requirements for workers;
7. The cost is lower than the painting process with the same effect;
8. In some applications, it has been explicitly stated that electrostatic spraying technology must be used for treatment;
9. During the electrostatic powder spraying process, there will be no common flowing phenomenon in the painting process;
10. The spraying effect is superior to the spraying process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc;
11. The development speed is fast. In addition to various effects such as hammer pattern, orange pattern, frosting, high gloss, matte, cracking, flashing gold, flashing silver, etc., in recent years, high-temperature resistant powder, internal low-temperature powder, high weather resistant powder, water-resistant powder, acid resistant powder, low-temperature curing powder, UV curing powder, etc. have emerged, making electrostatic powder spraying have a broader prospect.
Therefore, the electrostatic spray molding technology applied to warehouse storage shelf racks has the characteristics of high coating efficiency, excellent film performance, no solvent volatilization, minimal environmental pollution, low energy consumption, short production cycle, and easy implementation of coating automation.
