As the professional manufacturer, Qingguo Intelligent would like to provide you high quality powder spraying equipments. Powder spraying equipment is a professional tool necessary for electrostatic powder spraying. It can effectively connect a series of process links such as spraying, recycling, and powder supply, endowing the powder spraying process with high efficiency. The following is a detailed introduction to powder spraying equipment:
Powder spraying equipments usually includes the following main parts:
Powder electrostatic spray gun and its control device: This is the core component of powder spraying, which relies on high-voltage static electricity to transport the powder to the surface of the workpiece to be sprayed. The electrostatic and aerodynamic properties of the spray gun directly affect the powder loading rate and film thickness control.
Recycling device: used to recycle powder that has been sprayed or not adsorbed onto the workpiece. There are two common types of recycling devices: filter type and double cyclone type. The filter type recycling device has a simple structure, easy maintenance, and can recycle and use more than 99% of the powder spraying amount; The dual cyclone recycling device is suitable for color changing spray rooms and can bring faster color changing efficiency.
Powder room: Wrap the entire spraying process in a relatively enclosed environment to prevent powder overflow and protect the environment. PP, PVC, or specialized materials such as Apogee are often used as wall materials for powder rooms.
Powder supply device: The collected and screened powder is re supplied to the spray gun for recycling. The powder supply device uses compressed air to fluidized the powder and transports it to the spray gun through a powder conveying pipe.
Powder spraying equipments operates based on the principle of static electricity. During the spraying process, the powder is sprayed out through the spray gun and carries an electrostatic charge, which is achieved by using a high-voltage power supply in the spray gun. The surface of the coated object is usually coated with a layer of conductive primer first, so that the powder can adhere better during the spraying process. When powder with electrostatic charge is sprayed onto the surface of an object with opposite charge, the powder will be adsorbed onto the surface of the object, forming a uniform coating.
Environmental friendliness: Powder coatings do not contain organic solvents or volatile toxic substances, and there are no public hazards such as poisoning, fire, or "three wastes" emissions, which comply with environmental regulations.
Efficiency: The powder utilization rate is high, and the recycling rate of some well-known brands' powders can even reach over 99%. Meanwhile, the coating pre-treatment can be completed in one go without the need for primer, resulting in high production efficiency.
Excellent coating quality: Powder coating exhibits excellent mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the coating is dense, has strong adhesion, and good impact resistance.
Safety: Powder coating storage and transportation are safe and convenient, and through reasonable electrical safety measures and environmental control during the spraying process, the safety of operators and equipment can be ensured.
Powder spraying equipments is widely used in multiple fields, including construction (such as doors, windows, curtain walls, etc.), aluminum materials, household appliances, indoor furniture, outdoor furniture, electrical appliances, mechanical equipment, as well as fire protection and vehicle accessories. Products in these fields are treated with powder coating, which not only improves their appearance quality, but also enhances their corrosion resistance and durability.
Powder spraying equipment plays an important role in modern surface coating technology due to its high efficiency, environmental friendliness, and high quality.
