Fluidized bed which is composed by a porous separator and spray processing container, a porous separator is divided into upper and lower container portions. Their work is this: the container section below the bulkhead pass into the air, compressed air through a porous separator so that the role of the air flow above the powder were not suspended up in the top of the container and roll coating processing technology, presents "boiling "state. Preheated workpiece through the "boiling" powder coated area achieve results. Preheating temperature of the workpiece can be slightly higher than the melting temperature of the powder. The molecular structure of the dielectric can be divided into non-polar molecules and polar molecules of two. Dielectric polar molecules when subjected to an external electric field, showing electrical; dielectric non-polar molecules composed out well. After the paint spray nozzle atomization spray processing hardware, atomized paint particles through a needle or spray gun pole plate, cup at the edge of the spray by contact price charged spray processing, the gas generated by corona discharge when When the ionization region, will once again increase the surface charge density. Under these electrostatic field negatively charged paint particles, the polarity of the workpiece surface motion guide, and is deposited to form a uniform coating film on the surface of the workpiece. Spray processing quotes, spraying sand hung hardware appliances (certified), spray processing provided by the Dongguan City, Sha Hong Hardware Appliance Co., Ltd..
