Roller type

Roll coating is used to apply coating roll to the coated surface, and the coating machine is the main coating machine in the machine. The coating amount can be adjusted by measuring the pressure between the rolls, the pressure is strengthened, the amount of the coating is reduced and the coating amount is reduced. Type of roller coater:

1, press roller coater

2, reverse roller coater

3, transfer roller coater

4, gravure roller coater

Slot Coating

Slit coater, coating liquid storage tank; pump for the coating fluid coating liquid storage pot through a supply pipe pressure to a nozzle; control unit for controlling pump and nozzle working pressure detection section for detecting pipeline pressure, when the pressure reaches a predetermined pressure conditions when the nozzle out coating liquid.
