Activated aluminium oxide powderBased on the multi-pore structure and high-scale surface area, performance is prominent in the area of adsorption and catalyticization; normal aluminium oxide powder is mechanically long. Selecting a pair of types allows value to be served - adsorbing to cleanse the activity and resistant to grinding and filling。
I. Distinction between structural and physical performance
1. Different holes
Aluminium oxide powder is a multi-pore material with a rich micro- and meso-pore structure with a large surface area and excellent adsorption properties. This structure enables effective adsorption of moisture, impurities and multiple pollutants。
For normal aluminium oxide powder, which is usually a condensed structure with a lower pore rate and a relatively small surface area, it is less adsorptive and more inclined to structural material or functional filling applications。
2. Visible differences in surface area
Aluminium oxide powder is usually higher than the surface area and can provide more active bits, thus increasing adsorption efficiency and catalytic reaction。
Aluminium oxide powder is usually lower than the surface area, with greater emphasis on physical properties such as hardness, millability and stability。
3. Different adsorption capabilities
Aluminium activated oxide powder has good humidity and adsorption, with clear advantages in areas such as gas drying, water treatment and catalyst carriers。
Aluminium oxide powder is largely non-existent, with its main functions concentrated on mechanical performance and high temperature resistance。
Differences in production processes
Aluminium oxide powder, which is usually based on aluminium hydroxide or thin blubber, is prepared through special calibration and activation processes to form a stable multi-pore structure and thus achieve good adsorption and catalytic performance。
Normal aluminium oxide powder is produced mainly through high temperature burning, increasing crystal stability and mechanical strength and requiring lower control of holes。
Iii. Differences in performance stability
Aluminium oxide powder has good thermal stability and regenerative properties and can be reused by heating after saturation, with high economic value。
Aluminium oxide powder, although highly resistant to high temperatures, generally does not have the capacity to adsorb regenerate。
Iv. How to select suitable aluminium oxide powder
In practical applications, an enterprise should choose on the basis of the need for use:
For adsorption, drying or catalytic use, the choice of active aluminium oxide powder is recommended。
Normal aluminium oxide powder is more advantageous when applied in the field of grinding, filling or ceramic materials。
Priority should be given to activated aluminium oxide powder when comparing surface area, perforation and adsorption efficiency requirements are higher。
