Customized Sheet Metal Enclosure Powder Coating Service
Short Description
Powder spraying process, also known as powder coating, is a new coating process developed rapidly in recent decades. The raw material used is plastic powder. Coating can get thicker coating, such as coating 100~300μm coating, with general general solvent coating, about 4~6 times, and with powder coating is once can achieve the thickness. The coating has good corrosion resistance. The powder coating does not contain solvent, and has no pollution of three wastes. Using powder electrostatic spraying and other new processes, high efficiency, suitable for automatic line coating; High powder utilization rate, recyclable.a
Product Description
The purpose of dusting
The first is the protection, in order to prolong the life of the workpiece, followed by decorative, beautiful and pleasant. Again, for special purposes, to achieve special performance. Such as: sound insulation, heat insulation, fire prevention and so on.
According to the purpose of painting and different requirements, the coating of painting has several layers, including primer, putty, finish paint, etc.
Bottom paint: it is the lowest layer of coating that is in direct contact with the body of the coated workpiece. The role of the primer layer is to strengthen the adhesion between the coating and the body, and strengthen the protective performance of the coating. Ferrous metals should be phosphating before removal and non-ferrous metals should be oxidized before coating.
Be bored with child layer: to rough uneven airframe, use be bored with child layer to have a lot of shortcomings, such as construction trouble, reduce the binding force of coating and airframe.
The main purpose of the top coat is to add gloss to the product and is applied to the outermost layer of the coating.
The process flow
The workpiece passes through the conveyor chain to the gun position in the duster room to prepare for the spraying operation. Electrostatic generator through the nozzle electrode needle to the direction of the workpiece space release high voltage static electricity (negative), the high voltage static electricity from. A mixture of powder and compressed air from the nozzle and ionized (negatively charged) air around the electrode.
The workpiece is connected by conveying through the hanging device (grounding pole), so that an electric field is formed between the spray gun and the workpiece. The powder reaches the workpiece surface under the double push of electric field force and compressed air pressure, and forms a uniform coating on the surface of the workpiece by electrostatic attraction.
