Test machine: Open the film coating machine and confirm that the operation function of each operation link is normal and stop.
Stirring: The prepared film coating solution was passed through a 100 mesh sieve and poured into a blender for 40 minutes.
Adjust the flow rate: Move the spray gun to the fixed position on the outside of the coating pan, turn on the compressed air, turn off the atomizing gas valve, turn on the infusion pump to adjust the flow rate of the second spray gun (or multi-head spray gun) to the same amount, and then close the infusion pump.
Adjusting the atomization: Turn on the infusion pump and the atomizing air valve, adjust the atomization to the optimal state, and then turn off the compressed air and the infusion pump.
Loading: According to the capacity of the coating pan, pour the appropriate amount of core into the coating pan, and move the spray gun into the coating pan, adjust the distance between the spray gun and the core to fix the position of the spray gun.
Preheating: preset temperature, 45-50 ° C, open the coating pan to make the core flip (the speed of the coating pan is as slow as possible, as long as the core can be flipped). Turn on the hot air and the vacuum cleaner to slightly negative pressure, heat the core, and at the same time absorb the residual fine particles and fine powder in the core to the preset temperature.
Spraying: Accelerate the speed of the coating pan to the best tumbling state of the core, open the compressed air, infusion pump spray, and adjust the flow according to the characteristics of the core, generally 50kg a pot, the normal flow is 200ml/min, gradually grow from small to large Increase to the relative balance between flow and temperature, that is, reach the preset temperature and keep it from falling, and continuously spray to meet the coating quality standard.
End: After the liquid is sprayed to meet the quality standard, gradually reduce the temperature, gradually cool down, and slowly cool. Stop the spray, turn off the hot air for about 2-3 minutes, turn off the vacuum cleaner and the coating pan, and release the film.
