Alumina Ceramic Insulator Tube

Alumina Ceramic Insulator

Advantages of Alumina Ceramic Insulator Tube

Alumina ceramics themselves have a very high melting point, which endows alumina ceramic insulator tube with excellent high-temperature resistance.
The good insulation performance of alumina ceramic insulator tube can effectively block current conduction.
When the temperature changes, the thermal expansion of alumina ceramic insulator tube is relatively small.
The stable chemical properties ensure that the alumina ceramic insulator tube will not interfere with temperature measurement due to its own chemical reactions, ensuring the authenticity and accuracy of measurement data.

Factory Equipment

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.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
