Konstrukční prvky

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.

Oblasti aplikací

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.
