| i) Spraying method | |||||||||
| Compressed air spraying is available. All general spray guns (pressure feed type, gravity feed typeand siphon type) could be used. The caliber of spray nozzle is Ø0.8mm ~ 1.5mm, the spray headpressure is 1.50kgf/cm² ~ 4.0kgf/cm². The spray gun should keep a certain distance fromworkpiece in accordance with the spraying environment and coating properties. | |||||||||
| ii) Spraying process | |||||||||
| The spraying environment should be dry, well-ventilated, no smoking and fire.Air compressor should be degreased, dewatered and equipped with decantor beforeusing.Adjust atomization and oil pump capacity of the spraying gun, make sure theworkpiece is clean and level.Basecoat spraying: Heat the substrate to about 35°C before spraying basecoat.Basecoat film thickness: 15μm ~ 18μm; drying temperature: 120°C; drying time:l0min ~ 20min.Midcoat spraying: Spray midcoat after drying and cooling down the basecoat tonormal temperature.Midcoat film thickness: 20μm ~ 30μm.Topcoat spraying: Spray the topcoat directly after spraying the midcoat.Topcoat film thickness: 10μm ~ 12μm; drying temperature: 120°C ~ 150°C; drying time:l0min ~ 20min. | |||||||||
| iii) Film curing | |||||||||
| Set temperature within the drying oven (or tunnel drier) at 120°C ~ 150°C. Keep the sprayedworkpiece in for l0min ~ 15min, then slowly increase the temperature to 380°C ~ 400°C and keepfor another 5min ~ l0min.Please kindly note that both higher beginning temperature and rapid temperature increasingcould lead to blister of film.Besides, drying oven (or tunnel drier) should be well-ventilated, otherwise, the discolorationwill occur.Adjust the holding time according to the size of substrate and heat-transfer ability of the materialduring curing or sintering process. | |||||||||
| iv) Cool down the workpiece | |||||||||
| Water cooling, natural cooling and air cooling are all available. | |||||||||
| Storage of coating | |||||||||
| i. The storage place should be dry and well-ventilated. Avoid direct sun exposure,and keep away from the source of ignition and heat. The storage temperature should be between 10°C ~ 30°C . Have a weekly shake on the ball grinder ( 30rpm ~ 50rpm * 15min ~ 30min ). Never make it freeze in winter. ii. The shelf life of the coating is 6 months. |
