Ceramic Block For Band Heater


 

Introduction

Alumina ceramics is the most widely used fine ceramics material.   This material has  superb  material characteristics such as high electrical insulation, high mechanical  strength, high wear  and chemical resistance. Due to the important combination of    properties, we have thoroughly  researched the behaviour and characteristics of our  Alumina products to give you the best  possible component.

 Characteristics:

1). Excellent insulation ,security , long working life .
2). Precise grinding and polishing.
3). Excellent heat radiation, small size ,more environmental and energy-efficient .
4). good thermal conductivity 
5). large specific heat capacity 
6). low pressure drop        
7).  good heat-shock resisting ability
8). Working temperature: 600ºC-1200ºC

Parameters

Steatite

Steatite is lower in cost than Alumina but offers reduced mechanical properties.  However Steatite has very good electrical resistance properties, which are retained at  high  temperatures, along with moderate mechanical strength and temperature  resistance. It has been  used in electrical insulation for many years in both large-scale  electrical systems and electronic  and domestic appliances.

Characteristics:

Good to excellent electrical properties
High resistivity
Very low dielectric loss factor
Moderate strength
Low density

Application :

1). Gas cooker,Water heater,Gas oven, Gas boiler,Air-conditioning and so on.
2). As ceramic parts of flexible pad and channel heaters at operations of pre and postweld heat treatment; Welding process, stress-relieving, pre-heating & post heating, other resistance-heating environment
3). halogen lamps, high and low pressure uv lamps, mercury lamps, uv lamp holders and heating tubes.
4). high-power electrical applicance and all kinds of insulation device.
