Product Details

Roll To Roll Reverse Comma Coater with Intermittent and Continuous Coating Mode

Intermittent experimental coating machine is a three-roller transfer coating equipment. It can carry out continuous and intermittent coating, which is convenient to be applied to the equipment for surface coating process of various substrates. Especially used in the lithium ion battery industry. The equipment is designed to be convenient for researchers to use while meeting the requirements of coating accuracy and consistency, which is no different from production. The drying effect is excellent, and it is an ideal choice for the research and development and small tests of lithium ion batteries, super capacitors, nickel batteries and other secondary batteries.

Characteristic

*Substrate tension control, stable belt, configuration of correcting device;

*Hot air oven, double-sided airing on the top and bottom, good drying effect;

*Three-roll transfer coating with a wide coating window;

*Comma scraper metering, with precision adjustment mechanism, to achieve high coating accuracy;

*PLC control, touch screen operation, easy to use;

*Optional solvent recovery treatment device;
