Fumed Alumina for Modified Electrolyte The use of functional silane-modified alumina coating film can improve the adhesion between the coating and the diaphragm. At the same time, the functional groups can participate in the free radical polymerization of the electrolyte to form a colloidal electrolyte, thereby giving the battery good cycle stability and safety. The gas-phase alumina coating can promote the formation of colloidal electrolytes, and after functional modification, it can further promote the formation of colloidal electrolytes, thereby reducing electrolyte leakage.

Fumed alumina can generally be made into a dispersion product for use in the field of battery separators. This dispersion is water-based, has a high solid content and low viscosity, and the D50 particle size is approximately between 80-120 nanometers. Depending on the matching binder system, the pH value of the dispersion is either slightly acidic, slightly alkaline, or even neutral, and the Zeta potential is either positive or negative. When in use, the dispersion and the binder system are combined, and after adding a wetting agent, the final coating slurry is made. This slurry is coated on the surface of a PE separator to obtain a coating layer of approximately 1-4 microns, and after drying, a gas-phase nano-alumina coated modified separator is obtained.

Fumed nano-alumina is widely used in key materials of lithium batteries 1. Fumed alumina is mechanically mixed with positive electrode materials. Because the alumina particles are small, they can be coated on the surface of the positive electrode material to form a uniform and dense Al2O3 coating layer. 2. It can improve the capacity retention rate and battery life of the battery. 3. Generally, Fumed alumina products with a specific surface area of about 100m2/g are selected.

Fumed Nano-Alumina - powder coating Fumed nano-alumina (fumed aluminum oxide, Al₂O₃) is a nanostructured form of alumina produced through a flame hydrolysis process. Due to its unique properties, fumed nano-alumina can be used as an additive in powder coatings to enhance various performance characteristics. (1) It plays an isolating role to prevent powder from agglomerating; (2) It is adsorbed on the surface of the powder to play a "ball effect" and improve the fluidity of the powder; (3) It uses the unique surface electrical properties to eliminate static electricity and utilize the electrostatic repulsion effect to prevent agglomeration and improve fluidity.

By comprehensively utilizing silicon tetrachloride and hydrogen, byproducts of the polysilicon industrial process, as raw materials, fumed silica is produced. After the preheated material undergoes a high-temperature hydrolysis reaction, a gas-solid mixture containing a large amount of silica is obtained.

The application of silicon carbide classifying wheels in air flow mills provides efficient and accurate powder classification solutions through its high hardness, wear resistance, high temperature stability and chemical inertness. Whether in the pharmaceutical, food, fine chemical, electronic materials, ceramics and metal powder metallurgy industries, silicon carbide classifying wheels can significantly improve product quality and production efficiency, reduce maintenance costs and equipment wear. With the continuous advancement of industrial technology, the application prospects of silicon carbide classifying wheels in air flow mills will be broader.

Compared to traditional foods, micro-nano foods have higher added value and effectiveness, showing broader application prospects and economic value. Through precise classification, food particles can be processed into micro-nano foods with unique thermal properties, high surface atom activity, and size effects, significantly enhancing product solubility, adsorption, dispersibility, and bioavailability. For example, nano-scale rice starch, with its increased specific surface area, improves moisture absorption and contact with the gastrointestinal tract, enhancing absorption by the body. This not only boosts the nutritional value of the food but also improves its taste, aroma, and color. However, after ultrafine grinding, food particles often have large particle sizes and wide size distributions, affecting the quality of micro-nano foods. Therefore, precise classification of ultrafine ground food is necessary to obtain products with small and narrow size distributions. Air classifiers, effective dry classification equipment, are widely used in various industries, including mineral processing, chemical industry, pharmaceutical synthesis, semiconductor materials, and micro-nano foods. Current classifier wheels usually use straight blades for particle classification, but due to the smaller specific gravity, higher viscosity, and tendency to agglomerate of micro-nano food particles, traditional straight blade classifier wheels cannot meet their classification requirements. Therefore, it is necessary to optimize the structure of the classifier wheel blades to improve airflow speed and distribution within the classification chamber, enhancing classification efficiency and reducing particle size and distribution range. Using variable cross-section blades can reduce the radial speed between blades and the axial speed on the wheel's inner side, facilitating the smooth passage and quick collection of fine particles, thus improving classification efficiency. Additionally, these blades increase the tangential speed on the wheel's outer side, enhancing the centrifugal force on particles, allowing finer particles to be separated and collected, resulting in more precise classification. Simulation tests have shown that variable cross-section blades effectively lower the product's cut size, achieving smaller and narrower size distribution micro-nano food particles. This optimized design significantly enhances the performance of air classifiers in micro-nano food processing.

The classifying wheel is the core component of the airflow mill and classifier products, which is specially used for powder particle size sorting. Under the action of the fan suction, the material moves with the rising airflow to the classification area for coarse and fine material separation. The fine particles that meet the particle size requirements pass through the classifying wheel and enter the next component to be collected, and the coarse particles fall to the crushing area for further crushing. Features of SiC classifying wheel: High hardness and wear resistance High temperature stability Chemical inertness High-precision classification capability
