Progrannable Control Vertical Dip CoaterDip Coating machine

Product details

This machine is mainly used in sol-gel method to prepare many kinds of film materials on the same substrate. The different solution is placed on the rotary table, by setting the coating process, the substrate into solution dip coatings, the coating after the rotary table will be just below the solution film under a layer of automatic rotation to the substrate, the substrate drops into the solution dip coating, in order to complete the follow-up film. Films of different solutions, different materials and mixed immersion plating.

For example, the 123456 coating can be arranged in sequence according to the solution, or the 136425 coating can be arranged in accordance with the mixing. A single coating process can use up to 6 kinds of solution (material) to make multilayer film. The process parameters such as immersion, coating parameters, solution rotation and interval time of different layers are fully controlled by coating process

Many factors affect the film thickness, including viscosity, density, specific gravity, pulling speed and angle of dip solution, solvent viscosity, density, evaporation rate and environmental temperature and drying conditions.

Application:

Progrannable Control Vertical Dip Coater is a high-precision instrument suitable for the immersion pulling method of preparing a film by a sol-gel method (Sol-Gel method, referred to as SG method). The core components are imported with accessories to precisely control the pulling speed, and the coating is repeatedly repeated without positional deviation. The pulling speed, the pulling height, the immersion time, the number of cycles of coating, the falling speed, and the residence time can all be precisely controlled by the program. It is suitable for common substrates such as glass, Si (100), Si (111), sapphire (Al2O3), ceramic sheets, and resin substrates.

Introduction to immersion and pulling:

The immersion pulling method is to immerse the entire cleaned substrate in a pre-prepared sol, and then smoothly pull the substrate out of the sol at a precisely controlled uniform speed to form a layer on the surface of the substrate under the action of viscosity and gravity. The uniform liquid film is immediately evaporated by the solvent, so that the sol adhering to the surface of the substrate gels rapidly to form a gel film. The process diagram is as follows:

There are many factors affecting the thickness of the film, including the viscosity, concentration, specific gravity, pulling speed and pulling angle of the solution, viscosity of the solvent, specific gravity, evaporation rate, ambient temperature, drying conditions, and the like.
