-separation is also filtered coating mist (mist) and is set up acceptable working environment for spraying the worker;
-be usually designed to " independence " spraying room, different with so-called whole piece spraying coating line.
Most of this sprayings room all is combined with " spraying oven dry " device, is also referred to as " spraying is dry " room.Promptly behind spraying process, the spraying room can switch to drying mode.
Spray pattern is a kind of like this pattern: in the spray pattern process, operator (spraying worker) or automated system are on object or towards the object sprayed coating.Intake air temperature and spraying room temperature are set in about 20 ℃." excessive spray " and coating mist are discharged by exhaust and filtration apparatus, and air is discharged to outside the building that holds this device.
In ensuing drying mode, do not spray action, so air stream can circulate partly (though like this require), temperature is set in about 40 ℃-180 ℃.
" flash distillation " (flash off) (remaining in the evaporation of the solvent in the coating) that can occur in this dry run and actual dry run itself obviously are operating process time-consuming and power consumption (heating).
In addition, new coating will contain still less volatile organic constituents (voc ' s), and because environmental requirement, coating material will be water base for part.Thereby the longer time drying of these coating materials needs, and expansion drying efficient is more relevant with air movement, rather than temperature.
