Electrostatic spray powder coating line equipment
Electrostatic powder spraying equipment is a kind of surface treatment equipment commonly used in modern industrial production, which is widely used in the spraying process of home appliances, automobiles, furniture and other industries.
Electrostatic powder coating equipment process flow
Pre-treatment
Before spraying, the workpiece needs to be pre-treated, including degreasing, derusting and sanding, etc., to ensure that the surface of the workpiece is clean and flat, so as to prepare for the subsequent spraying process.
Pretreatment mainly involves preheating and dehumidifying the surface of the workpiece, which helps to improve the spraying effect and coating quality.
Electrostatic spraying
This is the core step in the process flow. In electrostatic powder coating equipment, the powder coating is evenly sprayed on the surface of the workpiece through the spray gun, while the static electricity generated by the spray gun makes the powder coating better adhere to the surface of the workpiece.
Curing treatment
After spraying, a curing process is required to make the coating stronger and more durable. This step is usually accomplished by heat or natural drying.
After treatment
Post-treatment is mainly for quality checking and repairing the finished workpieces to ensure that each workpiece meets the production requirements.
Spraying equipment features
Compared with traditional powder coating equipment, electrostatic powder coating equipment has the following significant features:
High efficiency and energy saving: electrostatic powder coating equipment adopts electrostatic spraying technology, which can make the powder coating better adhere to the surface of the workpiece, reduce the waste and improve the spraying efficiency. At the same time, its energy consumption is relatively low, which helps to reduce production costs.
Environmental protection and health: electrostatic powder coating equipment produces less waste during the spraying process, and powder coating is mostly environmentally friendly materials, which has less impact on the environment and human health.
High coating quality: due to the characteristics of electrostatic spraying technology, the coating is more uniform, smooth, and strong adhesion, not easy to fall off, improving the durability and aesthetics of the product.
Wide range of application: electrostatic powder coating equipment is suitable for spraying workpieces of various materials and shapes, which can meet the production needs of different industries.
