Application of Abrasion-Resistant Ceramic Pipes for Lithium-Ion Batteries

The lithium battery raw material conveying pipeline is severely worn by wind and powder erosion, especially at the bends, where the airflow changes direction, leading to significant wear on the outer side of the bends. In response to this condition, our company recommends using a wear-resistant ceramic-lined pipe. This pipeline is composed of three layers: steel, adhesive, and ceramic. The steel component is made of 304 stainless steel pipe, while the ceramic is bonded to the inner wall of the steel using high-strength adhesive. After being heated and cured, it forms a sturdy wear-resistant layer. This product is suitable for pneumatic conveying of powders and can operate stably without aging or shedding at temperatures below 150℃ for an extended period. Its lifespan is more than 4-5 times that of ordinary pipelines.

Selection Advantages

1. High Abrasion Resistance: Up to 4-5 times more wear-resistant than conventional pipelines under the same conditions.

2. Corrosion-Resistant: The inner ceramic lining can withstand acidic and alkaline corrosion.

3. Withstanding Moderate Temperatures: Capable of long-term operation under high temperatures; suitable for general operating conditions.

4. The interior and exterior surfaces are smooth with unobstructed airflow; the even surface allows materials to pass freely without any occurrence of material adhesion or blockage.

5. Easy Installation: 1/3 lighter than standard piping, it's easy to transport, saving labor, and installation is quicker and more efficient; allowing for pipes to be elevated higher with ease.

6. Reduce the load of suspended support equipment and save on material costs.

7. Reduced Maintenance: Excellent wear resistance significantly lowers the frequency of maintenance, saving costs and labor expenses.

Product Features

Our wear-resistant ceramic is a 95% Alumina ceramic, produced using 95% alumina powder, which is then formed through hot pressing casting and烧结 at 1700 degrees Celsius, resulting in a very dense sintered material that significantly enhances the wear resistance of the alumina ceramic.

It boasts the following features:

High hardness

The Rockwell hardness rating is HRA 82-85, ranking only second to diamond in hardness.

2. Excellent wear resistance

According to权威机构 tests, ceramic materials exhibit several times the wear resistance of common steel under erosion conditions.

3. Excellent shock resistance performance

Ceramics can be formulated to form strong crystal bonds, significantly enhancing the impact resistance of alumina ceramics.

4. Lightweight

Its density is 3.6g/cm³, less than half that of steel. Replacing other bulky wear-resistant materials with wear-resistant ceramics can significantly reduce the load on the equipment.
