Nano scale disperser for indium tin oxide optoelectronic applications

ITO conductive slurry nano homogenizer, also known as ITO nano homogenizer, is a suspension (solid/liquid) formed by the combined effects of strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, impact tearing, and turbulence in the narrow gap between the stator and rotor

ITO is an N-type oxide semiconductor - indium tin oxide. ITO thin film, also known as indium tin oxide semiconductor transparent conductive film, usually has two performance indicators: resistivity and transmittance. As a nano indium tin metal oxide, it has good conductivity and transparency, and can cut off harmful electronic radiation, ultraviolet radiation, and far-infrared radiation to the human body. Therefore, indium tin oxide is usually sprayed on glass, plastic, and electronic display screens as a transparent conductive film, while reducing harmful electronic radiation and ultraviolet and infrared radiation to the human body.

In oxide conductive films, In2O3 (ITO) films doped with Sn have the highest transmittance and conductivity, and are prone to etching fine patterns in acid solutions, with a transmittance of over 90%. The transmittance and resistance of ITO are controlled by the ratio of In2O3 to SnO2, typically SnO2: In2O3=1:9。Because when the thickness of tin oxide exceeds 200-, the transparency is usually not good enough - although the conductivity is good

The first requirement for conductive paste is dispersion uniformity. If the paste is unevenly dispersed and has serious agglomeration, the electrochemical performance of the battery will be affected. If the conductive agent is unevenly distributed, different electrochemical reactions may occur due to different conductivities of the electrode during charging and discharging, and a complex SEI film may form at the negative electrode. The reversible capacity may decrease, and there may be local overcharging and overdischarging phenomena or lithium metal precipitation, which may pose a safety hazard; The distribution of binders is uneven, and the bonding force between particles and between particles and the current collector can be too large or too small. The electrode resistance in areas that are too small can be high, and even material may fall off, ultimately affecting the overall capacity of the battery. Secondly, the slurry needs to have good settling stability and rheological properties, meet the requirements of the electrode coating process, and obtain a coating with uniform thickness. It is required that the thickness of the center of the battery electrode should be as consistent as possible with the thickness at the edge, which is the difficulty of the conductive slurry coating process.

Grinding and dispersing machine is a high-tech product composed of colloid grinding and dispersing machines.

The first level consists of three-level sawtooth protrusions and grooves with increasing precision. The stator can be infinitely adjusted to the desired distance between the rotors. Under enhanced fluid turbulence. The groove can change direction at each level.
The second stage is composed of a stator. The design of the dispersing head also effectively meets the needs of substances with different viscosities and particle sizes. The difference in the design of the stator and rotor (emulsifying head) between online and batch machines is mainly due to the requirements for conveying performance. It is particularly important to note that the difference between coarse precision, medium precision, fine precision, and other types of working heads is not only the arrangement of specified rotor teeth, but also an important difference in the geometric characteristics of different working heads. The width of the slot and other geometric features can alter the different functions of the stator and rotor working heads.
