Intermittent Lab Coating Machine

Intermittent Lab Coating Machine

The intermittent lab coating machine is a three-roll transfer coating equipment, which can be used for continuous and intermittent coating. It is convenient to be used in the surface coating process of various substrates. Especially in the lithium ion battery industry, the equipment is convenient for researchers to use, while meeting the requirements of coating accuracy and consistency is the same as the design of production, drying effect is excellent, is lithium ion batteries, super capacitors, Ideal choice for nickel batteries and other secondary battery R & D and small trials.
Feature:
1. Can freely switch to realize continuous and intermittent coating;
Base material tension control, stable strike-band, and equipped with rectifying devices;
Hot-air oven, blowing on top and bottom, with good drying effect;
Three roll transfer coating with wider coating windows;
Comma scraper metering, with precision adjustment mechanism, to obtain high coating accuracy;
PLC control, touch screen operation, easy to use;
Alternative solvent recovery treatment units;
