Spraying of coating | ||||
i) Spraying method | ||||
Compressed air spraying is available. All general spray guns (pressure feed type,gravity feed type and siphon type) could be used. The caliber of spray nozzle is Ø0.8mm-1.5mm, the spray head pressure is 1.50kgf/cm² ~ 4.0kgf/cm². The spray gun shouldkeep a certain distance from workpiece in accordance with the spraying environmentand coating properties. | ||||
ii) Spraying process | ||||
a) The spraying environment should be dry, well-ventilated and has no dust. Reducethe impact on spraying quality caused by spraying environmental factors.b) We recommend preheating the substrate at 40°C-80°C before spraying, payattention to the uniformity and thickness of film during spraying and keep the dryfilm thickness in the range of 38μm±17μm. | ||||
iii) Film curing | ||||
Dry the sprayed workpiece from 50°C, and increase the temperature slowly, (sinteringcondition: 250°C * 30min or 300°C * l0min) . Both over high beginning temperature and rapid temperature increasing could leadto blister.Adjust the holding time according to the size of substrate and heat conductivity ofthe material during curing process. | ||||
iv) Cool down the workpiece | ||||
Both natural cooling and air cooling are available. | ||||
torage of coating | ||||
i. The storage place should be shady, dry, well-ventilated, and should keep away from the source of ignition and heat. It can be stored for 3 months at the temperature of 5°C ~ 25°C. Be stored at a temperature above 30°C or below 0°C is forbidden. If it is left unused for long time, shake twice a day at a speed of 120rpm ~ 200rpm to preventthe coating from settling, deteriorating, and seeding.ii. After mixing, the coating can be stored at 5°C ~ 15°C for 36 hours, 15°C ~ 30°C for 24 hours, and at about 5°C for 72hours ( we suggest the unused coating being storedat about 5°C ). Be stored at a temperature above 30°C or below 0°C is forbidden. |
