White cylindrical porous alumina ceramic tube

Le white cylindrical porous alumina ceramic tube is an advanced industrial ceramic component made mainly from high-purity alumina (Al ₂ O3) through precision molding and high-temperature sintering. Its core feature is the presence of a large number of uniform and controllable micrometer sized through pores inside, forming a high specific surface area and excellent permeability.
Porous alumina ceramic tubes not only inherit the excellent characteristics of structural ceramics such as high strength, high hardness, wear resistance, corrosion resistance, and high temperature resistance, but also possess special functions such as separation, filtration, gas distribution, permeation, and catalytic support due to their unique porous structure. Its appearance is a standard cylindrical tube with a white and smooth surface, high dimensional accuracy, and can be flexibly customized according to actual application scenarios. It is an ideal choice for solving technical problems under various harsh working conditions.

Resolve the following core issues:
The filtration challenge in high temperature environments: Traditional metal or polymer filter materials cannot work stably for a long time in high temperature and corrosive environments. This product can withstand temperatures up to 1600 ℃ and resist acid and alkali corrosion, achieving efficient purification of high-temperature gases and molten metals.
Precision gas distribution and diffusion requirements: When it is necessary to evenly and finely disperse gas into a liquid or another phase (such as aeration, air flotation), ordinary pipe fittings will produce large bubbles, which is inefficient. Porous ceramic tubes can generate uniform and small bubbles, greatly increasing the gas-liquid contact area and improving reaction or treatment efficiency.
Performance bottleneck of catalyst carrier: Many catalytic reactions require carriers with high specific surface area, good heat resistance, and mechanical strength. This product provides a stable and efficient attachment platform for catalysts, preventing the sintering and loss of active ingredients, and improving catalytic efficiency and catalyst life.
The lifespan and reliability issues of traditional materials: In complex environments where wear and corrosion coexist, metal components are prone to damage and plastic components are prone to aging. The excellent wear and corrosion resistance of alumina ceramics can significantly extend the service life of equipment, reduce downtime and maintenance costs.

Principaux domaines d'application
White cylindrical porous alumina ceramic tubes are widely used in the following industrial and technological fields due to their multifunctionality:

1. High temperature gas filtration and dust removal
   High temperature smoke and dust treatment systems applied in industries such as metallurgy, carbon black, chemical engineering, and waste incineration. As a filter element, it can effectively capture small dust particles in high-temperature flue gas, achieve ultra-low emissions, and recover valuable heat energy and raw materials.
2. Metal melt filtration
   It is a key material for improving the quality of castings in industries such as aluminum, copper, and cast iron. Used for filtering molten metal, it can effectively remove non-metallic inclusions, oxides and other impurities in the melt, significantly improve the microstructure of metal materials, and enhance the density, mechanical properties and yield of castings.
3. Gas distribution and diffusion device
   Wastewater treatment: used as an aerator (aeration tube) to provide uniform and efficient oxygen delivery in aerobic biochemical treatment tanks, promote microbial metabolism, and save energy and reduce consumption.
   Chemical reaction: As a gas distribution element in the reactor, it evenly disperses gas reactants in the liquid, enhances mass transfer process, and improves reaction rate and yield.
   Air flotation technology: used to generate fine bubbles that adhere to suspended solids in water, causing them to float and separate. It is widely used in wastewater treatment in industries such as papermaking, food, and printing and dyeing.
4. Catalyst carrier
   Catalytic reaction devices applied in fields such as automobile exhaust purification, petrochemicals, and coal chemicals. Its high specific surface area and thermal stability make it an ideal carrier for various catalysts, widely used in reactions such as dehydrogenation, hydrogenation, SCR (selective catalytic reduction), etc.
5. Sensors and insulation materials
   A protective sleeve that can be used for certain high-temperature sensors, allowing medium penetration and providing mechanical protection.
   Its porous structure gives it a low thermal conductivity and can also be used as an insulation material in high-temperature environments.
