  • Ceramic Seal Rings High hardness and Heat Resistance Alumina Zirconia Seal Wafer Ring


    Ceramic sealing ring adopts advanced hot vulcanization technology to make special alumina corundum wear-resisting ceramics according to certain layout.This structure not only gives play to alumina ceramics resistance to high temperature wear and corrosion resistance, but also gives play to the characteristics of high strength, high toughness and good sealing of rubber materials, integrated design, easy to replace and install.

    Feature of ceramic sealing ring 

    1)  High hardness.

    2)  High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is

    widely used in areas where resistance to high temperatures is essential.

    3) Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.

    4) High electrical resistivity : Alumina is an electrically insulating material.

    5)High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and

    alkaline solutions.

    6) Good chemical stability of alumina leads to high corrosion resistance.
     

    Advantages of the ceramic seal rings
    1. The sealing ring in the working pressure and a certain temperature range, should have good sealing performance, and with the increase of pressure can automatically improve the sealing performance.
    2. The friction between the sealing ring device and the moving parts should be small and the friction coefficient should be stable.
    3. The sealing ring has strong corrosion resistance, not easy to aging, long working life, good wear resistance, and can be automatically compensated to a certain extent after wear.
    4. Simple structure, easy to use and maintain, so that the sealing ring has a longer life.
