perform
1, environmental protection
No irritating and harmful gas release; Harm of mineral-free cotton floating objects to human skin and respiratory tract; The toxicity of tobacco production is safe (AQ 1). There is no harmful gas and waste emission during production, construction and installation, and the carbon emission is small. There is no environmental pollution caused by repeated heat preservation and waste removal.
2, fire and high temperature resistance
The fire-resistant temperature of cement foamed insulation board can reach 1000℃ or above, and its combustion performance is A 1. It is a kind of incombustible material, which has excellent fire resistance.
3, high thermal insulation
The closed-cell ratio of cement foamed insulation board is greater than 97%, which significantly reduces air convection heat transfer. The lowest thermal conductivity of cement foamed insulation board can reach 0.045W/m*k, which is basically equivalent to polystyrene board and can meet the needs of building insulation.
4. Light weight and high strength
Cement foam insulation board solves the technical problem of contradiction between low density and high strength of materials, and achieves relative unity. The density is 180kg/m3, and the compressive strength is above 0.2MPa, which meets the requirements of transportation and engineering application for strength.
