Application
Alumina ceramic tube is mainly applied to wear, serious scour of material handling occasions, such as coal-fired power generation, metallurgy, coal, mining, industry, and other geological materials pipeline, as well as the use of electronic appliances such as insulation pipe; alumina ceramic rods is widely used in the industry of resistance to temperature and thermostat, as a resistance ceramic matrix and two-metal thermostat used in ceramic-top column.
Notice
1. Alumina products are fragile. Please handle them carefully and avoid collision during unpacking, transportation, handling and cleaning
2. Check whether any micro-cracks exist before using alumina products. Products with micro-cracks should not be used.
3. Alumina products should be completely dry before usage. If they get wet, let the crucible or tube dry naturally before using them. If dry crucibles by placing in a dryer or oven, make sure that the dry process goes slowly.
4. Do not load too many materials in Alumina Tubes, which can increase the possibility of uneven heating.
