Inorganic Insulation Board Foamed Cement Board

Inorganic insulation board foamed cement board, also known as cement foamed insulation board or foamed concrete insulation board, is a type of insulation material manufactured using foamed cement technology. It is primarily made from materials such as ordinary Portland cement, fly ash, foaming agents, and additives through processes including compounding, mixing, foaming, and cutting. It features lightweight, bubble-like thermal insulation properties.

Features

Green and Eco-friendly: The production and construction processes emit no harmful gases or waste, and there is no pollution from repeated insulation removal and disposal.

Fire Resistance and High-Temperature Tolerance: With a fire resistance temperature of up to 1000 degrees Celsius and a combustion performance rating of A1, it offers superior fire safety.

High Thermal Insulation: With a closed-cell rate of over 97% and a thermal conductivity as low as 0.045 W/(m·K), it meets the thermal insulation requirements for buildings.

Low Water Absorption: It does not mold in humid environments, ensuring product safety and durability.

Lightweight and High Strength: With a density of 180 kg per cubic meter and a compressive strength of over 0.2 MPa, it meets the strength requirements for transportation and engineering applications.

Long Lifespan and Aging Resistance: It has a lifespan of over 50 years, synchronizing with the building's lifespan, meaning only one insulation installation is needed throughout the building's life.

Good Freeze-Thaw Resistance: After 25 consecutive freeze-thaw cycles, the mass loss rate is less than 5%, and the strength loss rate is less than 20%.

Excellent Sound Insulation: Its internal structure contains numerous independent bubbles, providing sound absorption 5-7 times that of ordinary concrete, with sound insulation effectiveness reaching up to 60 dB.

Good Workability: It is homogeneous with mortar and wall surfaces, has excellent interface properties, and can be directly adhered after simple cleaning, with strong adhesion.

Low Cost: Overall, it can reduce building insulation costs by 3-5 times.

Application Areas

Building Envelope Wall Insulation Engineering: Used for fire isolation belts in external wall insulation.

Roof Insulation Board: Used for thermal insulation of roofs.

Fire Door Core Board: Used as internal filling material for fire doors.

Production Process

Feeding and Mixing: Quantitative amounts of cement, foaming agent, and foam stabilizer enhancer are added to the mixer via the feeding system and dry mixed for 30 seconds.

Mixing: A定量 amount of warm water is added to the mixer for wet mixing for 2 minutes; then a定量 amount of foaming agent is added and mixed for 8-15 seconds.

Molding and Foaming: The slurry is poured into molds for foaming, which takes about 3-5 minutes.

Initial Curing: After molding, it is left to stand for several hours for initial curing.

Demolding: Demolding can be done once the foamed cement insulation board has achieved initial setting and possesses initial strength.

Cutting: The demolded foamed cement insulation board blank, having attained certain strength, is then cut.

Final Curing: The curing period for the foamed cement insulation board should be no less than 7 days.
