Powder electrostatic spraying
Powder electrostatic spray gun head metal guide ring connected to high voltage anode, aluminum earthing form the positive, when compressed air to powder for powder from the barrel of the duct to the spray gun guide ring, the negative electric field and make the powder with negative charge, discharge in electrostatic force and compressed air, under the joint action of powder from the gun flew to adsorbed on the surface of aluminum and evenly, after heating, powder melt and flow flat to a uniform coating
Wood processing
Wood grain processing began to introduce in the late 1990s, mainly used for the surface treatment of interior decoration profiles. Wood processing mainly USES the transfer process, it is after powder electrostatic spraying qualified aluminum surface with a layer of printed with certain patterns (wood grain, marble) permeable membrane, and then pumping air into vacuum state, the osmosis membrane completely covered in aluminium profile surface, after heating, make the ink transfer on the permeable membrane, seeping into the powder coating, so that the aluminum surface formation and osmosis membrane on the appearance of the design is exactly the same. Wood processing is conducted on powder coating, therefore, preparation of powder coating and powder coating material production working procedure is exactly the same, just the powder used must be compatible with hot osmosis membrane, otherwise may not easily on the lines, and the film thickness should be controlled in 60 ~ 90 (including m.
The process flow of wood grain processing is:
Pretreatment, powder spraying, baking, inspection, manual lamination, vacuum, furnace heating, release vacuum, cooling tear film, inspection package
Vacuum degree should be controlled rationally, and the vacuum degree too high or too low will result in unpatterned or blurred image. Transfer printing temperature should be controlled in 175 ~ 195 ℃. The temperature is high, the defects such as chromatic aberration, print spot, the temperature is too low, can cause the pattern blurred.
