Talking about the inert alumina filler ball of alumina ball
There are many types of alumina balls, and different alumina balls are used in different scenarios. For example, activated alumina balls can be used as desiccants, and inert alumina balls can be used as bottom filling materials for hydrocracking refining equipment and catalytic reforming equipment. The media department of Moku.com will talk about the alumina filler balls of alumina balls.
Alumina filler balls, also called inert alumina ceramic balls, "inert" means that its chemical reaction is weak and will not play a catalytic role. The texture of alumina filler is very dense, so the water absorption rate is very low, and it cannot be as drying as activated alumina balls. We often see inert alumina packing balls in petroleum, chemical, fertilizer, natural gas and environmental protection industries. In these industries, they are used as covering support materials and tower packings for catalysts in reactors.
Do you know how alumina filler balls are processed?
The superfine-grain calcined alumina micropowder is the raw material of alumina filler balls. After being stirred and mixed by automatic mixing equipment, it is formed by a ball forming machine, and then calcined at a high temperature tunnel kiln at 1600°C to finally form. Alumina packing balls can withstand high temperature and high pressure, and can also resist the corrosion of acids, alkalis and other solvents. They not only have stable chemical functions, but also have good thermal stability. Its role is to add gas or liquid distribution points, which can support and protect active catalysts with low strength.
Taking 99% φ20mm alumina packing balls as an example, its compressive strength is about 13KN/piece, its water absorption rate is less than 5%, its bulk density is ≥1900kg/m³, and its resistance to sudden temperature changes is greater than 850°C. It has acid and alkali corrosion resistance. Advantages, it can be used as a material for filling the bottom, and is very popular among users.
Technical indicators of alumina packing balls
The content of alumina determines the data of various indicators of alumina filler balls. Generally, the higher the content of alumina, the better the performance and the higher the price. Users can choose according to their needs.
