The applications of high strength aluminium silicate boards

图片
Here are some key characteristics and applications of high strength aluminium silicate boards : Composition - Made of highly compressed aluminium silicate fibers held together with a mineral binder. Density - Boards have a high density of 800-1000 kg/m3, contributing to their durability. Strength - Compressive strength exceeds 50-70N/mm2, making them suitable for load bearing applications. Rigidity - Modules of elasticity above 15,000 N/mm2 results in rigid, dimensionally stable boards. Temperature Resistance - Withstands temperatures up to 1250°C without damage, decomposition or pulverization. Low Thermal Conductivity - Achieves k-values as low as 0.12 W/mK, retaining heat efficiently. Applications - Used as furnace lining boards, kiln shelves, ladles, tundishes, back-up insulation, plugging & patching. Advantages - High strength to weight ratio reduces structural costs, dimensional stability withstands thermal shocks/vibration. Sizes - Available in standard sizes like 1000...

The key point of customized ceramic fiber vacuum

图片
 Here are some key points about customized ceramic fiber vacuum insulation : Vacuum Insulation - Removing air from between porous ceramic fibers reduces thermal conductivity, providing R-values over R30 per inch. Core Material - Alumina-silica or aluminosilicate fibers less than 5 microns in diameter allow evacuating the core without collapse. Core Shapes - Can be manufactured in sheets, panels, cylinders or custom fabricated geometries to fit unique equipment requirements. Envelope Material - A gastight metal or polymer envelope containing core maintains vacuum and seals out air/moisture long-term. Thermal Performance - Conductivity as low as 0.002 W/mK at mean temperatures, outperforming even aerogel insulation. High Temperature - Many types rated for temperatures up to 1000°C or more in non-combustible ceramic form. Pressure Vessels - Suitable for high vacuum jacketed vessels, pipes requiring minimal heat loss over lifetime. Customization - Core thickness, shapes, sealing ...

The characteristics of 1430°C refractory industry insulation ceramic fiber blocks

图片
 Here are some key characteristics and uses of 1430°C refractory industry insulation ceramic fiber blocks : Temperature Resistance - Capable of continuous use up to 1430°C without degradation, damage or loss of insulating properties. Low Thermal Conductivity - Achieves excellent heat retention with a thermal conductivity of only 0.13-0.15 W/mK, inhibiting heat transfer. Lightweight - At just 128 kg/m3, the blocks are easy to handle and install compared to denser materials like firebricks. Moldable - Can be easily cut, drilled or molded on-site to fit complex commercial or industrial furnace geometries. Durability - Maintains strength and impermeability even after years of high temperature cyclic use in corrosive environments. Non-combustible - Made from alkaline-earth silicate fibers that will not fuel combustion or emit toxic fumes in a fire. Applications - Ideal for lining kilns, furnaces, boilers operating up to 1430°C in steel, glass, petrochemical plants and other proces...
