High-temperature resistant foamed cement board

High-Temperature Resistant Foamed Cement Board

High-temperature resistant foamed cement board is a high-performance inorganic insulation material with excellent fire resistance and high-temperature performance, as well as a wide range of applications. The following is a detailed introduction to high-temperature resistant foamed cement board:

Definition and Characteristics

High-temperature resistant foamed cement board is a lightweight, bubble-like thermal insulation material made from ordinary Portland cement, fly ash, foaming agents, admixtures, and other materials through processes such as compounding, mixing, foaming, and cutting. Its main characteristics include:

Green and Eco-Friendly: No harmful gases or waste emissions during production and construction, and no release of irritating odors or harmful gases.

Fire and High-Temperature Resistance: Withstands temperatures up to 1000°C, rated A1 for combustion performance, and offers superior fire safety.

High Thermal Insulation: Closed-cell rate exceeding 97%, thermal conductivity as low as 0.045 W/(m·K), meeting building insulation requirements.

Lightweight and High Strength: Density of 180 kg/m³, compressive strength above 0.2 MPa, suitable for transportation and engineering applications.

Long Lifespan and Aging Resistance: Lifespan exceeding 50 years, synchronized with building lifespan, eliminating the need for repeated insulation construction.

Good Frost Resistance: After 25 freeze-thaw cycles, mass loss rate less than 5%, strength loss rate less than 20%.

Excellent Sound Insulation: Sound absorption capacity 5-7 times that of ordinary concrete, sound insulation effect up to 60 dB (140 mm).

Good Workability: Homogeneous with mortar and wall surfaces, excellent interface, and strong adhesion.

Low Cost: Overall cost is low, reducing building insulation costs by 3-5 times.

Application Areas

High-temperature resistant foamed cement board is widely used in the following fields:

Building Envelope Wall Insulation Projects: Used as fire insulation belts for external wall insulation.

Roof Insulation Panels: Used for thermal insulation of roofs.

Fire Door Core Panels: Used in the manufacturing of fire doors.

Production Process and Market Prospects

The production process of high-temperature resistant foamed cement board includes feeding, mixing, stirring, foaming, cutting, and other steps. Its market prospects are broad, especially in construction projects with high fire safety requirements, such as data centers and cold chain logistics. With the promotion of green building standards and increasing demand for high-temperature resistant materials, the market outlook for high-temperature resistant foamed cement board is very optimistic.
