Continuous production and dip-lifting film coating device and application method thereof

Abstract

The invention relates to the field of dip-lifting film formation and particularly relates to a continuous production and dip-lifting film coating device and an application method of the continuous production and dip-lifting film coating device. The device comprises a base, a film coating chamber, a film drying chamber, a transmission device and a solvent recycling device, wherein the film coating chamber is provided with an agitating paddle for agitating slurry, a slurry thickness adjustable knife edge and a slurry flowing baffle, an idler wheel, a feeding opening of the slurry and a discharging opening of the slurry, wherein basic cloth is unreeled to be lifted by the idler wheel to prepare a film; the film drying chamber is provided with a heating plate, a temperature sensor and an exhausting opening; the transmission device comprises a speed adjustable dragging device; the speed adjustable dragging device drives the idler wheel with changeable direction and controllable speed; the solvent recycling device is inserted into the film drying chamber through an air guide pipe. The continuous production and dip-lifting film coating device has the advantages that film preparation can realize continuous small-batch production and the production efficiency is improved; in a preparation process, the lifting speed is adjustable and the precision is high; the continuous production and dip-lifting film coating device is environmentally friendly and is easy to operate; a prepared film has good uniformity and consistency; the device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of dipping and pulling film formation, in particular to a device for continuous production of dipping and pulling coating and a method for using the same. Background technique [0002] The dipping and pulling method is to immerse the entire cleaned substrate in the pre-prepared sol, and then pull the substrate out of the sol at a precisely controlled uniform speed, and form a uniform layer on the surface of the substrate under the action of viscosity and gravity. Then the solvent evaporates rapidly, so the sol attached to the surface of the substrate gels rapidly to form a gel film. The dipping and pulling method is a commonly used film preparation method. This method can be used to coat a uniform film on the base film and base cloth substrate. It is widely used in the pulling of sol-gel, solution and suspension to form a film. [0003] At present, most universities and research institutions rarely have special dippi...
