As a wet precision slit coating technology, the fully automatic double-layer coating die has the following working principle: the fluid conducted by the vector pump is transferred to the current collector along the slit of the coating die under a certain pressure and flow rate.
产品概述
As a wet precision slit coating technology, the fully automatic double-layer coating die has the following working principle: the fluid conducted by the vector pump is transferred to the current collector along the slit of the coating die under a certain pressure and flow rate. Two different active substances or slurries can be coated on the same surface at the same time in a wet film state . The upper and lower layers are independently controlled and closed-loop adjusted through the data fed back by the surface density meter, which can meet the requirements of double-layer continuous and double-layer gap coating. Both the upper and lower layers are adjusted by micrometers.
