Description

Multifunctional powder coating platform

technical field

The invention relates to the technical field of spraying equipment, more specifically, to a multifunctional powder spraying platform.

Background technique

Powder spraying is to use powder spraying equipment to spray powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; The final coating with different effects; the spraying effect of powder spraying is superior to the spraying process in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance, and the cost is also lower than that of spraying with the same effect.

In the powder supply device, the powder is in a fluidized state, which is achieved by the action of compressed air, and then the powder is carried by the high-speed air flow through the siphon effect, forming a powder-air mixture, and passing through the Venturi powder pump , powder delivery pipe, and finally reach the spray gun.

The powder delivered to the spray gun can be adjusted. Specifically, the parameters of the powder and air can be adjusted separately, the powder output and the atomization state of the powder can be changed, so that different coating thicknesses can be achieved to meet the needs of different products. The powder supply has sufficient capacity to provide adequate pressure and flow even with a 50 foot long powder hose to the gun.

The high voltage and low current generated by the electrostatic generating device make the electrode needle located at the front of the spray gun discharge in the air. When the powder is sprayed out through the nozzle of the gun head, the powder particles are charged, and are transported by electrostatic adsorption and airflow. Double action to reach the grounded workpiece surface.

The spray gun can generate enough voltage to ensure the maximum coating effect. The maximum voltage can reach 100kV. When spraying inner corners or deep cavities, the spray gun can effectively overcome the Faraday cage effect and ensure that each surface of the workpiece that is required to be sprayed can be sprayed. Achieve good coverage and uniform film thickness.

Powder coating uses the principle of electrostatic spraying to absorb the dry powder on the metal aluminum profile. After baking at a high temperature above 200 ℃, the powder solidifies into a solid and bright coating about 60 microns thick. Make the surface of the product smooth and uniform, with strong acid resistance, alkali resistance, crash resistance, wear resistance, and can withstand the erosion of strong ultraviolet radiation and acid rain for a long time without coating powdering, fading, and falling off. Powder sprayed aluminum profiles have a service life of up to 30 years under normal conditions. Its surface coating is guaranteed not to fade, discolor or crack within 5-10 years. Its weather resistance and corrosion resistance are better than ordinary aluminum materials, and its color diversity.
