Wrought Iron Furniture Powder Coating
On the Method of Powder Painting of Wrought Iron Furniture
The quality of wrought iron furniture is strong and beautiful. If you want to make it last for a long time, and the color is constant, the technique of powder coating is very important.
Powder coating, the first surface treatment. The body of wrought iron, or stained with oil or rusted, must be cleaned and its rust removed to get a good foundation. You can use lye to degrease, and remove rust by acid to ensure that the surface is clean and flawless. If it is pristine, it is the foundation for painting.
Then choose powder. The quality of powder is related to the success or failure of painting. It is advisable to choose those with high quality, pure color and strong adhesion. The color should be in line with the style of the furniture, or simple and deep, or bright and bright, all of which are appropriate. And the weather resistance of the powder cannot be ignored. It can withstand wind and rain without fading, and it can withstand cold and heat without deformation.
The method of powder application includes electrostatic spraying and fluidized bed dipping coating. For electrostatic sprayers, by the force of electrostatic electricity, the powder is adsorbed on the wrought iron surface, uniform and fine, such as fog condensation branches. When operating, the distance, angle, and moving speed between the spray gun and the workpiece need to be accurately grasped in order to obtain a flat effect. Fluidized bed dip coating, the preheated wrought iron is immersed in the fluidized powder bed, and the powder is heated and melted to adhere. This method is suitable for workpieces with complex shapes and can ensure no dead ends.
However, after applying powder, curing is also critical. It is necessary to control its temperature and time to fully cross-link and cure the powder. If the temperature is too high, the powder will easily change color and foam; if the temperature is too low, the curing will be incomplete, which will affect the performance of the coating. The time also needs to be appropriate. If it is long, the energy consumption will increase greatly, and if it is short, the curing will be insufficient.
In short, the powder coating of wrought iron furniture, from the surface, powder selection, powder application to curing, is interconnected and indispensable. Make good use of its method to make wrought iron furniture glow and shine, and it will be handed down for
