Brief introduction

It is specially designed for the research work on the preparation of thin film materials in liquid phase (especially the sol-gel method), and grows thin films on different liquids by dipping and pulling. The lifting speed, lifting height, impregnation time, coating times (multiple multilayer coatings), and coating interval time are continuously adjustable and accurately controlled. There is no special requirement for coating substrate, flake, block, cylindrical and so on can be coated. Stable operation, no vibration of liquid surface during operation, can greatly improve the accuracy of the experiment. Used in scientific research, product production.

Product application

This product is mainly used for preparing film materials by sol-gel method and other liquid phase methods. The clean and dry substrate is immersed in the solution (sol), and the impregnated substrate is lifted vertically at a certain speed through the pre-set parameters. A film is attached to the substrate, called a "wet gel film", and with the volatilization of the solvent in the "wet gel film" film layer, the film layer solidifies on the substrate into a "dry gel film". After further drying and high temperature heat treatment, the "dry gel film" can obtain the required nano-film material. The thickness of the film is determined by the pulling speed, liquid concentration and liquid viscosity.

Product introduction

The dip coating machine is specially designed for the research work of preparing film materials in liquid phase (especially sol-gel method), and the film is grown by dipping and pulling different liquids. The lifting speed, lifting height, impregnation time, coating times (multiple multilayer coatings), and coating interval time are continuously adjustable and accurately controlled. There is no special requirement for coating substrate, flake, block, cylindrical and so on can be coated. Stable operation, no vibration of the liquid surface during operation, can greatly improve the experimental accuracy and efficiency.

Applicable to the surface coating process of silicon, wafer, glass, ceramic, metal and other solid materials. Used in scientific research, product production.

Product characteristics

1. Servo motor drive, with the original imported ball screw vertical lifting device and program control system to ensure the running accuracy and stability; Servo motor running high precision, smoothness, no jitter and other characteristics are incomparable to the stepper motor. The original imported vertical lifting device has the characteristics of high precision, no transmission gap, smooth operation, corrosion resistance, maintenance free, long service life and so on.

2. Multi-parameter automatic program control. There are six parameter Settings: descent speed, impregnation time, lifting speed, coating size, coating times, coating interval time, each parameter is continuously adjustable and precise control. After the coating program is set, the entire coating process from drop to dip to lift coating is fully automatic.

3. Smooth operation at both high and low speeds, no vibration on the liquid surface during coating, so that the film layer is more uniform and no stripes.

4. 4.3-inch LCD touch screen makes the control more convenient. When running, the parameters are displayed in real time, and the coating process is more intuitive.

5. The upper and lower ends are installed with limited position sensors. When lifting or dropping, it will automatically stop at the limit to avoid the over-limit operation of lifting or dropping.

6. Using a unique design of flat mouth fixture, both sides of the sample evenly clamp, will not clamp bad sample.
