Causes and solutions for poor fluidization during spraying 1) The compressed air pressure is not enough. Check the compressed air supply, clean the air filter equipment, and increase the pressure appropriately. 2) The microplate is blocked, and it can be checked whether the microplate is blocked by oil or impurities in the ultrafine powder or compressed air. 3) The powder is stored in the powder supply bucket for a long time to absorb moisture. Try to increase the pressure of the gas for a long time to vulcanize the powder, take away the moisture, and use a clean utensil to help stir if necessary. 4) The powder is agglomerated, and the powder can be loosely sieved by hand. 5) Too much powder in the vulcanized bed can reduce the amount of powder in the bed, and the amount of powder is generally added to two-thirds of the volume of the vulcanized bed. Reasons and solutions for poor surface hardness after curing of powder coatings 1) Insufficient curing, can raise the baking temperature, make it meet the process requirements or extend the baking time of the workpiece to meet the process requirements. 2) Excessive curing, coating embrittlement will also reduce the hardness, and can appropriately lower the baking temperature and shorten the baking time. 3) The baking temperature rise rate is too slow. During the slow melt flow, some leveling aids migrate to the upper floating, which can increase the heating rate to the surface of the coating film. 4) The quality of the powder itself can be notified to the powder supplier to improve the formulation. Causes and solutions for discoloration of coating film after curing of powder coating 1) The baking time is too long, which can shorten the baking time. 2) The baking temperature is too high to lower the baking temperature. 3) The coating thickness is not uniform. a) The position or direction of the spray gun is incorrect. Due to the influence of the Faraday effect, the spray gun should be inspected and reset. b) The vibrator of the automatic spray gun does not match the production line speed, and the production line speed should be adjusted or the gun vibrator stroke should be adjusted; c) The airflow in the dusting chamber affects the spray range of the powder and should be contacted by the equipment supplier; d) The spray gun is not evenly distributed. The powder supply and spray gun system should be checked to ensure that the powder is vulcanized and atomized evenly; e) The output voltage should be checked for high voltage instability. 4) The air in the oven is not clean, the air heating system and exhaust should be checked. 5) There is a problem with the powder formulation and should be contacted by the powder supplier.
