Coating the Organic Film

The coating of organic film is called the inner coating generally. The raw materials of coating is dissolved into the organic solvent and then painted to the surface of the label. As for the whole process of coating, generally, the guniting is successive; the roller of the host machine, hot air, and discharge air work from beginning to end.

Coating of Water Phase Film

As for the coating of water phase film, take the water as the solvent. And then the film formation, plasticizer and pigment are added to form several water phase film solvent. During the whole process, the guniting is successive; the roller of the host machine, hot air, and discharge air work from beginning to end.

Operation methods: (air spraying system)

★All the air spraying guns are installed on the rotating arms with the good position after the peristaltic pump pipeline is installed. And then move the rotating arm and spraying gun to the outside of the roller to try to spray.

★Open the ball valve on spraying air pipeline and the pressure is adjusted to 0.3~0.4Mpa.

★Press the guniting button, start the peristaltic pump, adjust the rotating speed so as to make the solution pump enter into the spray gun. Adjust the governing screw on the top of the spray gun for increasing or reducingthe spray pressure to reach the ideal spray requirements. 

★The rotating arm and the spray gun are rolled in the coating roller to start the normal working.

Maintenance of Equipment:

Electrical maintenance of host control system:

★The whole set of electrical equipment shall be inspected and maintained after working for 50 hours

★The host elements in the system such as the contactor, relay and PLC shall be plug in style when they are installed so as to maintenance. If the overhaul is necessary, the users shall change all the contactors and relays according to the conditions and adjust the heat relay regularly.

★Use the clean cloth to swap the probe of the electrical switch regularly
