Zirconia containing ceramic fiber paper gasket is a high-temperature special gasket made from zirconium containing ceramic fiber cotton as the core material, wet formed into cardboard, and then processed by punching or cutting. Due to the addition of zirconia component, it has better high-temperature resistance and stability compared to ordinary ceramic fiber gaskets, and plays a key role in sealing, insulation, and other high-temperature industrial scenarios.
Core performance of zirconium containing ceramic fiber paper gasket
Ultra high temperature tolerance: This is its core advantage, with a classification temperature of up to 1430 ℃, which can work stably in a high-temperature environment of 1350 ℃ for a long time. It can also directly contact flames for hot surfaces, far exceeding the temperature resistance level of ordinary aluminum silicate ceramic fiber gaskets, and is suitable for the working conditions of various high-temperature thermal equipment.
Comprehensive mechanical and thermal properties: tough and elastic texture, strong wind erosion resistance, outstanding machinability, can be stamped into different shapes according to equipment requirements; At the same time, it has low thermal conductivity and minimal heat storage, which can significantly reduce equipment heat loss. It also has excellent thermal shock resistance and is not easy to crack or detach in the face of severe temperature fluctuations during equipment start-up and shutdown.
Safety and chemical stability: Belongs to asbestos free products, will not release toxic gases at high temperatures, and meets environmental protection requirements; Its total content of Al ₂ O ∝+SiO ₂+ZrO ₂ can reach 99%, with strong chemical stability, able to resist the erosion of most corrosive flue gases and molten materials at high temperatures, and not easily powdering or deteriorating.
The volume density of zirconium containing ceramic fiber paper gasket is usually 260-320kg/m ³, which can be flexibly adjusted according to the usage scenario; The thickness can be customized according to needs, and the thickness commonly used for gaskets is in the range of a few millimeters; The compressive strength reaches 0.5 MPa or above (when the thickness direction shrinks by 10%), and the permanent linear shrinkage rate is low. After insulation at 1350 ℃ for 24 hours, the shrinkage rate is only 3%, which can maintain dimensional stability for a long time and ensure sealing and insulation effects.
