Emergency Stop Accessories for Electrostatic Spraying Equipment with Fast Response Time
Equipment Description:
Principle of electrostatic spraying process: Use electrostatic powder spraying equipment (electrostatic spraying machine) to spray powder coating onto the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating; the powder coating is leveled and solidified after high-temperature baking to become a final coating with different effects (different types of powder coating effects); the spraying effect is better than the painting process in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance, and the cost is also lower than the painting with the same effect.
1. Core advantages of equipment Efficient spraying : The maximum processing capacity of a single machine is 300㎡/h (the workpiece spacing is ≥0.5m) Precise adsorption : Intelligent adjustment of electrostatic field strength, complex surface coverage rate reaches 98% Zero pollution emission : 100% solid powder utilization, no VOC generation
2. Safety protection design Triple interlocking protection: Overvoltage/overcurrent/excessive powder concentration automatically cuts off the power supply Emergency stop response time <0.2 seconds Comply with GB 5226.1-2025 "Mechanical and Electrical Safety" standard
