High-Quality Ceramic Fiber Inorganic Boards
Product Overview
Ceramic fiber inorganic boards are high-temperature refractory insulation materials mainly composed of high-quality ceramic fibers and solidified using inorganic binders. They combine lightweight properties, high strength, excellent heat resistance, superior thermal insulation, and good chemical stability, making them widely used for insulation in high-temperature industrial equipment and kilns.
With an inorganic binder formulation, these boards are non-combustible, non-toxic, environmentally friendly, and safe to use, meeting the demands of modern industries for high-performance, energy-efficient, and eco-friendly materials. Ceramic fiber inorganic boards can replace traditional refractory bricks while offering outstanding thermal and mechanical properties, making them an ideal insulation choice across various industries.
Product Composition and Structure
Ceramic fiber inorganic boards are primarily composed of the following elements:
(1) Ceramic Fiber Yarn or Blanket Material: Made from high-purity alumina-silicate ceramic fibers with high-temperature resistance and uniform fiber fineness.
(2) Inorganic Binder: Specially formulated high-temperature inorganic binders that maintain stable bonding strength at elevated temperatures, ensuring the structural integrity of the boards.
(3) Auxiliary Fillers: Lightweight aggregates, refractory fibers, and other additives are incorporated in specific proportions to adjust board density and mechanical properties based on performance requirements.
(4) Reinforcing Materials: Some products include high-temperature-resistant fiber meshes or filaments to enhance mechanical strength and impact resistance.
