Design Features
Alumina ceramic stirring wheel is a stirring component made of high-purity alumina (Al2O3) ceramic material, which is widely used in industrial stirring scenes with high wear resistance, corrosion resistance and high temperature resistance. The following is a detailed description:
1. Material properties
Composition: Alumina content is usually 92%~99.9% (divided into different grades according to purity, such as 95 porcelain, 99 porcelain).
High hardness: Mohs hardness reaches 9 (second only to diamond), and wear resistance is excellent.
Corrosion resistance: Resistant to strong acids (such as hydrochloric acid, sulfuric acid), strong alkalis (such as sodium hydroxide) and organic solvents.
High temperature resistance: Long-term use temperature can reach 1600°C (depending on purity), and good stability at high temperature.
Insulation: Non-conductive, suitable for electronic or special chemical environments.
2. Structural design
Shape: Common impeller type, turbine type, paddle type, etc., can be customized according to stirring requirements.
Surface treatment: can be polished to mirror-grade finish to reduce material adhesion.
Connection method: usually fixed to the stirring rod through a metal sleeve or ceramic thread.
Áreas de Aplicação
3. Application fields
Chemical industry: stirring corrosive liquids (such as electroplating solutions, acid and alkali solutions).
Medicine/food: mixing processes with high cleanliness requirements (avoiding metal contamination).
Mining/metallurgy: grinding mineral slurry or high-temperature molten metal.
Electronics industry: uniform dispersion of semiconductor materials and lithium battery slurry.
