Alumina ceramic tube—a sturdy guard for industrial transportation

Alumina ceramic tubes occupy an important position in material conveying links in many industrial fields due to their excellent performance. In the lithium battery production industry, Suzhou Yijia New Material Technology Co., Ltd.'s wear-resistant alumina ceramic composite pipe has become the focus of the industry. The pipeline adopts the composite technology of alumina ceramic lining with 95% Al ˇ O content and steel parts, the Mohs hardness reaches Grade 9, the wear resistance is more than 10 times higher than that of ordinary pipelines, and the pipeline can withstand the high temperature environment of 300℃ for a long time, effectively solving the pipeline wear problems in the links of pneumatic conveying system and powder raw material treatment in lithium battery production.

From the perspective of manufacturing process, alumina ceramic tubes have strict requirements on raw materials. The purity of alumina powder usually needs to reach more than 99%, and the particle size ranges from a few microns to tens of microns, so as to ensure the formation of alumina ceramic tubes during subsequent molding and sintering processes. Uniform and dense ceramic structure. In molding technology, isostatic pressing molding, extrusion molding and other advanced technologies are often used. Isostatic pressing can make ceramic powder subject to uniform pressure in all directions, and obtain ceramic green bodies with uniform density and complex shape, which can meet the production of pipe parts with special specifications and shape requirements.

Looking forward to the future, with the technological innovation of lithium batteries and other industries, the requirements for high temperature resistance and thermal shock resistance of alumina ceramic tubes will become more refined and diverse. New ceramic materials, such as silicon carbide ceramics, with higher thermal conductivity and strength, are expected to be more widely used in the field of future material transportation pipelines, further improving pipeline performance and reliability.
