subject: Powder Coating Equipment - A Comprehensive Information Source [print this page] Resin powder is sprayed on the surface of heated elements by powder coating equipment. As the surface cools down, the powder fuses and cools to create a protective coating. These powder coating equipment are available in single components, kits, package, coating outfits as well as entire systems made up of different elements needed for the the complete coating method.
The spray paint outfits consist of the spray gun, spray cup, pressure tank, pump, nozzle, hose and supplementary attachments. handy portable packages may be easily carried to plants, development and building sites. Sub-systems may include extra elements or upgrades for certain systems or sub-systems. These usually consist of mud collectors, water devices, pumping units, dip tanks, spray guns, plating powder supplies, booths and roller coating heads.
Other sorts of powder coating equipment are fluidized bed systems as well as electrostatic coating equipments. As soon as coating powder and paint droplets are electrically charged by electrostatic coating equipments, They can now be sprayed on the other electrically charged material. Because it is a well-known undeniable fact that opposite electric charges are drawn to one another, the electrically charged paint droplets would be drawn to electrically charged target surfaces. This is beneficial in lowering over spraying and using excess paint.
Screens or porous beds are employed by fluidized bed mechanisms. Air is blown upward via the screen to suspend coating particles that create a fluid bed of coating. Powder coating sticks to the uncovered components of hot parts which are sunken into the fluidized bed. To make thicker coating, the particles are electrically charged before application.
You will find totally different selections for electrostatic technology and charging. The corona powder coating method uses an electric field between the charged powder cloud and electrically charged part to make the coating stick. With the corona powder coating technique, a high voltage energy supply is used to separate air to produce a flow of negative ions. This imparts a like charge to the powder cloud. Charged powder dust particles coming from the spray gun are drawn to the opposite electrical ion of the component.
Friction is employed by the tribostatic powder device coating for an efficient and even finish. The spray gun is supplied with turbulators to improve the stream of coating elements. Movement velocity is elevated and the tube bore of the gun is restricted. the friction that is generated on the outside of the hose charge the powder particles. The non-conductive materials and the spray gun doesn't create electrical charge between them. This technology has its restrictions and can be used for chosen powder formulations only. Tribostatic powder coating is more generally applied for radiators to heat homes and structures, grocery store shelves, etc.
