"400 adiabatic board made of xonotlite, a high-temperature resistant composite board with high density", "Xonotlite" typically refers to high-density, high-strength calcium silicate insulation products, with xonotlite as its main crystalline phase. High-density xonotlite itself is characterized by high density, which brings better compressive strength and dimensional stability, but with a slightly higher thermal conductivity. Its density is usually between 200–300 kg/m³ or even higher (compared to about 150–220 kg/m³ for ordinary calcium silicate boards).
Characteristics of different types of xonotlite products
Excellent thermal insulation performance: low thermal conductivity and microporous structure effectively prevent heat transfer
Ultra-high temperature resistance: The maximum operating temperature can reach 1000~1050°C, far exceeding that of ordinary calcium silicate
Excellent mechanical properties: bulk density of 300 ± 10% kg/m³, compressive strength ≥ 2.4 MPa, flexural strength ≥ 1.0 MPa, and resistance to fragmentation
Long-term durability: no pulverization, no shrinkage, no deformation at high temperatures, good chemical stability, and long service life
Safety and environmental protection features: 100% asbestos-free, free of harmful substances such as formaldehyde, non-combustible (Class A1), non-absorbent, non-nutritious to organisms, mold-resistant and antibacterial
Convenient construction: It can be sawed, cut, and drilled, with flexible installation, suitable for various complex working conditions
Application fields of xonotlite
Metallurgical industry: insulation for aluminum electrolytic cells, lining for metallurgical heating furnaces, and equipment for molten metal processing
Building materials industry: insulation for cement kilns, backing insulation for glass kilns, and thermal insulation layers for ceramic kilns
Power and Chemical Industry: steam pipelines, thermal pipelines, petrochemical equipment, boiler flues, and insulation for reaction vessels
Industrial kilns: Various high-temperature kiln backing materials cannot be used as working layers to directly contact the flame
In the field of architecture: fireproof partitions, thermal insulation for buildings in high-temperature environments, and fireproof cladding for steel structures
