Insulation layer of foam cement board security advantages of floor heating and roof insulation, there are still certain applications, but it is decreasing, With foam cement insulation board this fast completely fireproof, low cost, speed of construction products, has been largely foam cement insulation board replaced. Now used in all developed countries to warm insulation layer foam cement insulation board, has reached more than 30% of the application rate of foam cement insulation board to warm insulation layer. According to the momentum of development, it will 100% replace polystyrene foam. And Styrofoam, foam concrete has the following advantages and competitiveness: a high heat. The braking command vulnerability of the polystyrene foam is the low temperature heat, and began to break down, when the temperature continues to rise, it will thermofusible shrinking at 74 ℃. Hot water pipes to warm the temperature is not constant, and sometimes more than 74 ℃, which will cause the polystyrene foam thermal decomposition of the insulation failure. Foam cement insulation board, cement inorganic materials, heat-resistant up to 500 ℃, there is no thermal decomposition, and thus last longer and will not cause insulation failure. 2, green, non-toxic and harmless. The foam cement insulation board does not contain any toxic ingredients, foaming agent and various additives are not volatile and harmful substances, is conducive to the indoor environment. Styrofoam thermal decomposition release styrene toxic gases. Therefore the use of foam cement insulation board more environmentally friendly than the use of polystyrene foam. 3, the intensity ratio of polystyrene foam. Compressive strength of polystyrene foam, only 0.02 to 0.03MPa, and 200 to 300 kg / m3 foam cement compressive strength of insulation board for of 0.6 ~~ ??0.8 MPa, and better resistance to stress. 4, the use of lower cost. The current price of self-extinguishing polystyrene foam is about 150 to 170 yuan / m3, the total cost of 200 to 300 kg / m3 foam cement insulation board was only 100 yuan, the cost is lower than the polystyrene foam 30 % to 40%, with a clear economic advantage. 5, the construction speed. The foam concrete pouring smoothing both, do not need a picture of laying, construction speed faster than polystyrene foam board 1/3. 6, no seams, and reduce the heat loss caused by the seams. Polystyrene foam board is a picture of laying, there are a lot of seams, easy to form a the cold bridge or thermal bridges. The main raw material: 1, ordinary portland cement 42.5 or 32.5. If you want to fast-setting, rapid hardening Portland cement or sulfur aluminate cement; 2, one or two of fly ash, slag powder and other active admixture; 3, the blowing agent. When using rapid hardening Portland cement or sulfur aluminate cement, various foaming agents may be used; 4, ordinary portland cement procoagulant agent. Improve ordinary portland cement setting speed to reduce the bubble burst; 5, anti-water absorbing agent, moisture resistance capability enhanced products, water-resistant, reduce water absorption.
