Alumina Ceramic Tube

  • Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.

  • Isostatic pressing: During the isostatic pressing procedure, binders are blended with the ceramic powder. As a result of this process, the powder transforms into freely flowing granules that can effortlessly fill the molds.

  • Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.

How to clean alumina ceramic tube

1. Begin by vacuuming the outside of the tube to remove any debris or dust. 

2. Use a mild detergent and scrub the tube with a soft cloth or brush.

3. Use a mild abrasive or a toothbrush to scrub the inside of the tube.

4. Rinse the inside and outside of the tube with warm water and a soft cloth. 

5. Use a clean, lint-free cloth to dry it.
