Advantages and Disadvantages of Foaming Cement Thermal Insulation Board
1, the physical foam: the blowing agent through the mechanical equipment prepared into a bubble, and then added to the foam by the cement-based cementitious materials, aggregates, admixtures, admixtures and water from the slurry, the mixing , Pouring molding, curing from the insulation board.
2, the chemical foam: the foam agent added by the cement-based cementitious materials, aggregates, admixtures, admixtures and water from the slurry, the mixing and mixing, pouring it in the mold through the chemical reaction Leaving the inside of the slurry to produce closed pores, the conservation, cutting insulation board.
Foam cement insulation board is the wall insulation and wall insulation fire isolation zone with the best insulation material, its advantages are: low thermal conductivity, good insulation effect, not burning, waterproof, strong adhesion with the wall, high strength , Non-toxic radiation substances, environmental protection. With the building life of the same period, and the construction is simple and fast. Technical performance is better than foam glass, foam ceramic, phenolic foam board, polystyrene particles, polystyrene board, extruded board and other wall insulation materials. Its shortcomings are: low strength (brittle), high water absorption, can not be with foam glass, foam ceramic, phenolic foam board, polystyrene particles, polystyrene board, extruded board and other wall insulation materials compared.
According to the different production methods can be divided into physical foam insulation board and chemical foam insulation board.
