How to operate powder coating equipment correctly? Safety uidelines for use

Powder coating equipment is an indispensable tool in modern industrial production, and its high efficiency and environmentally friendly features make the coating process more convenient. However, as a kind of equipment involving static electricity, high pressure and chemical substances, the use of powder coating equipment puts high demands on operational practices and safety. To ensure the efficient operation of the equipment and the safety of the operator, it is important to know the correct operating methods.

Preparation is a critical step before officially operating powder coating equipment. Before starting the equipment, it is important to check that all components are in good condition, ensuring that there is no damage or abnormality to the spray gun, power supply system and powder recovery system, and that the pipework is tightly connected to avoid air leaks. The workplace environment should also be adequately prepared. The spraying area must be clean and well ventilated to avoid dust build-up or moisture that could affect the operation of the equipment. In addition, operators need to wear protective equipment, including protective masks, gloves, suits and anti-static shoes, to avoid the effects of powder on the skin and respiratory tract, and to prevent accidents caused by static build-up.

Equipment start-up needs to be carried out in strict accordance with standard procedures. Firstly, switch on the air compressor to ensure that the air pressure is stable in the range specified by the equipment, then start the powder supply device and electrostatic spray gun in turn, and adjust the powder flow and electrostatic voltage to achieve the ideal spraying effect. Before formally spraying the workpiece, it is recommended to carry out test spraying to confirm whether the spraying status of the equipment is normal. During the test, keep a proper distance between the spray gun and the workpiece, usually 15 to 20 cm, and pay attention to whether the spraying angle is in accordance with the process requirements, so as to avoid uneven coating or waste of powder due to the distance being too close or too far.

In the spraying process, the precision of operation directly affects the quality of coating. The moving speed and manoeuvre of the spray gun need to be kept stable. The operator should move the spray gun in a smooth and even manner to ensure even coating. The control of electrostatic voltage is also crucial. Too high a voltage will cause the powder to fly apart, while too low a voltage may affect the adhesion of the powder, which should be adjusted appropriately according to the material of the workpiece and the coating requirements. In addition, the operating status of the powder recovery system should be continuously monitored, and the blockage should be cleared in time to avoid waste or pollution caused by powder leakage.

After the spraying operation is completed, the cleaning of equipment and environment should not be neglected. After the equipment is switched off, the operator should use special tools to clean up the residual powder inside the powder supply unit and spray gun, and at the same time check the cartridge in the powder recycling system, and replace or clean it regularly to ensure its operating efficiency. The workplace should also be fully cleaned up to avoid the accumulation of powder particles causing secondary pollution to the surrounding environment. Unused powder should be properly stored in a dry, ventilated place and away from ignition sources to maintain the stability of powder performance.

Safe operation is always the key point to be emphasised in the powder coating process. When using powder coating equipment, you must be highly alert to fire hazards. The powder coating process generates a build-up of static electricity, so the operating area should be protected against static electricity and there should be no open flames or flammable materials. The high-voltage part of the equipment is forbidden to be touched or disassembled during operation, and any abnormal situation should be stopped immediately to avoid forcing the operation to cause safety accidents. In order to improve the overall standardisation and safety of the operation, the company should also provide regular training to the operators, so that they are familiar with the use of the equipment specifications and emergency treatment methods.

Correct operation of powder coating equipment can not only improve production efficiency and coating quality, but also effectively reduce the safety hazards. Through standardised operating procedures and scientific maintenance management, companies can achieve efficient operation of equipment, while providing a safe working environment for operators. Whether it is daily use or special circumstances of the operation of the norms, should follow the ‘safety first, prevention first’ principle, in order to protect the production of smooth progress.
