Welche Auswirkung hat die Größe einer Kugel mit hohem Aluminiumoxidgehalt auf die Leistung??

Eine Kugel mit hohem Aluminiumoxidgehalt ist eine Hohlkugelstruktur aus Aluminiumoxidmaterial, das viele hervorragende Eigenschaften und Merkmale aufweist. The size of high alumina balls has a significant impact on their performance. The influence of the size of alumina hollow spheres on their performance will be analyzed from several aspects below.

The size of high alumina balls has a significant impact on their mechanical properties

Smaller alumina hollow balls have higher strength and hardness. This is because the mass of the hollow sphere is determined by its wall thickness and diameter. A smaller diameter means a relatively larger wall thickness, which can provide sufficient strength support. Deshalb, smaller alumina hollow balls have better mechanical properties in terms of compression resistance, bending resistance, und Schlagfestigkeit.

The size of the alumina milling ball has a certain impact on its thermal conductivity

Smaller alumina hollow balls have better thermal conductivity. This is because the smaller hollow sphere has a thinner wall, a shorter heat conduction path, and a faster heat conduction speed. Deshalb, in some application fields that require efficient thermal conductivity, choosing smaller alumina hollow spheres can improve the overall thermal conductivity performance.

The size of alumina hollow spheres has a significant impact on their specific surface area and porosity

Larger alumina milling balls are relatively smooth and have a smaller specific surface area. The smaller alumina hollow spheres have a relatively larger surface area and more pore structure. This makes the smaller alumina hollow spheres have better performance in adsorption, catalysis, and ion exchange. Zum Beispiel, smaller alumina hollow spheres can serve as efficient catalyst carriers, providing more active sites and a larger active surface area, thereby enhancing the catalytic effect.

The size of high alumina ball will also affect their density and buoyancy

According to Archimedes’ principle, the buoyancy of a hollow alumina sphere is related to its volume, and the volume is closely related to its size. Deshalb, larger alumina hollow spheres have relatively greater buoyancy and can be suspended in the liquid, while smaller alumina hollow spheres may settle at the bottom of the liquid.
