Before understanding electrostatic powder spraying equipment, we must first understand its main components. A complete set of electrostatic powder spraying equipment system mainly consists of pre-spraying treatment, dehydration drying system, powder spraying room spraying system, powder supply equipment, high temperature curing Furnace, electrostatic spray gun and control device, electrostatic generator and powder secondary recovery equipment.
Before powder coating, the workpiece needs to be pre-treated for foreign objects, oil stains and stains on its surface, such as degreasing, rust removal, silane treatment and water washing, etc. It may also need to be polished and sandblasted if necessary. Cleaning to improve coating bond strength. Only through the pretreatment of this process, the processed workpiece can ensure the uniform film thickness and firm adsorption of the coating.
After the pre-treatment, the workpiece needs to be dehydrated and dried, and the water marks can be entered into the powder spraying room system for powder spraying; when the sprayed workpiece is finished, the workpiece needs to be sent to the oven for baking within a certain period of time, so that the powder can be sprayed. After the coating is heated, a complete coating film is formed according to different process requirements. Common curing methods include hot air circulation and thermal radiation baking.
The powder spraying room is an important part of spraying. A high-quality powder spraying room can save the manufacturing cost for the enterprise. Now the powder spraying room should be made of stainless steel plate or imported PP plate. Such a powder spraying room is strong and durable; The powder spraying room also needs to be reasonably designed, which can be optimally designed according to the principle of aerodynamics, which can not only effectively prevent powder spillage, but also obtain a relatively stable airflow field in the powder spraying area, so as to reduce the interference of the airflow formed by the exhaust on the powder spraying process to a minimum. Lower degree!
