Alumina Ceramic Rod

Alumina ceramic round rod is a kind of ceramic rod, is also a kind of alumina ceramic products.

Alumina ceramic round rod

Features of the alumina ceramic round rod:

A. Strength is higher than the clay ceramics, the hardness is very high, have a very good wear resistance;

B. High temperature resistance, can be used in 1600 high temperature degrees;

C. Strong corrosion resistance;

D. Good electrical insulation performance, in the high temperature electrical insulation performance is particularly outstanding, per millimeter thickness can withstand a voltage of more than 8000V.

Anything has good must have bad, then do you know what is the disadvantage of alumina ceramic round rod?

The disadvantages of alumina ceramic round rod are:

Low toughness, poor heat and shock resistance, can not withstand the sharp changes in temperature.

Corrosion resistance

It has excellent chemical properties and resistance to metal erosion

Strong wear and corrosion resistance

High temperature resistance, good insulation performance

99 Alumina ceramics can withstand high temperature up to 1700 degrees
It is a typical alkaline refractory
Excellent insulation at high voltages, various frequencies and high temperatures

Alumina ceramic round rod

Manufacturing process of alumina ceramic round rod:

Raw material batching grinding processing pulp, mud molding drying powder hot pressure sintering inspection (cold processing) packaging storage factory.

The forming methods of alumina ceramic round rod are often used: dry pressure, grouting, extrusion, isostatic pressure (dry method, wet method), injection coagulation, flow extension, hot die casting, centrifugal grouting, etc. Different ceramic circle help, because of its requirements, size, complex shape and accuracy, need to adopt a reasonable forming method.

Preparation of powder of alumina ceramic rod:

First, the aluminum powder is prepared into powder materials according to different requirements and different forming processes.

The second is forming.

When using extrusion molding or injection molding, binder and plasticizer should be introduced into the powder. Generally, the thermoplastic plastic or resin organic adhesive with a weight ratio of 10-30% should be evenly mixed with the alumina powder at 150-200 temperature to facilitate the molding operation.
