How can powder coating equipment be environmentally friendly?
1. Dust pollution when the spray gun of powder spraying equipment is working.

Remedy: On the premise of not affecting the powder spraying work, increase the recovery power of the fan by 15%, and use a water mist mixing device at the discharge end to vigorously recover the fine particles in the powder, and then discharge it to the tested atmosphere to meet the standard. But it inevitably increases the cost for users.

2. Oven sources of pollution are mainly caused by coal-fired heating.

Repair method: Use natural gas or liquefied petroleum gas in places where conditions permit, and use bio-particle furnaces for heating in places that do not have powder spraying equipment but need to install water filtration equipment.

3. The main pollution sources of the coating production line are: VOC, formaldehyde, xylene, alcohol ether and other harmful volatile particles pollute the air.

Treatment method: After installing water curtain and plasma photo-oxygen waste gas treatment equipment in the spray booth of powder spraying equipment, discharge it outside after reaching the standard.

4. The pre-treatment of industrial metal products before spraying should be mainly shot blasting, and a shot blasting treatment room should be set up, and dust filtering equipment should be installed, and discharged to the outside after reaching the standard.
