HOW IS THE POWDER COATING PROCESS FOR A IRON WIRE PRODUCT?
The term "powder coating" generally refers to the process of applying a powder coating to products, which is a surface treatment technology widely used on various metal products to provide a coating for anti-corrosion, decoration, or other functional purposes. Here is the general process of powder coating for iron wire products:
Pretreatment:
1. Cleaning: Use a degreaser to clean the iron wire surface of oil.
2. Descaling: Remove the oxides on the iron wire surface through acid washing or mechanical methods.
3. Water washing: Thoroughly clean the residue after acid washing.
4. Phosphating or passivation: To improve the adhesion of the coating to the substrate, sometimes phosphating or passivation treatment is required for the iron wire.
5. Drying: Use an oven or other methods to thoroughly dry the iron wire.
Powder coating:
1. Electrostatic spraying: The iron wire is charged with positive charge when passing through the electrostatic spraying equipment, while the powder coating sprayed by the gun is negatively charged. Due to the mutual attraction of charges, the powder is evenly adhered to the surface of the iron wire.
2. Flow control: Ensure that the powder flow rate from the gun is stable to ensure uniform coating thickness.
Curing:
1. Send the powder coated iron wire into the curing furnace.
2. In the curing furnace, the powder coating melts and flows evenly at a certain temperature to form a uniform coating.
3. After a certain curing time, the coating is fully hardened.
Cooling:
Cool the finished iron wire to room temperature to ensure the performance of the coating and facilitate subsequent processing.
Inspection:
1. Visual inspection: Check whether the coating is uniform, whether there are any particles, bubbles, peeling defects, etc..
2. Thickness testing: Use a coating thickness gauge to test the thickneess of the coating whether it meets the requirements.
3. Performance testing: such as corrosion resistance test, adhesion test, etc.
Post-processing:
1. Process the unqualified products by grinding, repairing, etc.
2. Pack the qualified products and prepare for shipment.
The entire powder coating process requires strict control to ensure the quality of the final products. At the same time, in order to meet environmental requirements, the wastewater, exhaust gas and waste residue in the process need to be treated to meet discharge standards.
