Powder coating powder can good resin, epoxy powder is better, some powder coating powder manufacturer not powder, some manufacturers on polyester powder are more difficult (separate will grind epoxy, polyester jet plate), friction gun jet flow is obviously better than static gun, and friction to squirt gun thicker coating, coating without the disadvantage of high pressure gun, such as hair flower big orange peel phenomenon.
3. Reasonable selection of packing: fineness and dispersion of packing are closely related to powder.
The precipitation powder is higher than that of normal ultrafine heavy barium, and barium sulfate is better than that of calcium carbonate.
4, increase the charged auxiliaries: in the formula to add the right amount of conductive auxiliaries (action mechanism: can make the powder particles with more charge.
There is a strong electric field in the area between the high-pressure electrostatic spray gun and the workpiece, and the air is ionized to generate hundreds of millions of ions. When the powder particles of the electrifying agent pass through this area, they are polarized, and it can capture more negative ions and bring more charge.
For the dead corner of the groove and other parts because the Faraday effect power line is weak, then the powder particles with more charge can reach the surface of the workpiece by their own power, so as to improve the powder of these parts.
