Foamed cement insulation board is made of ordinary Portland cement, fly ash, foaming agent, admixture, etc., and is made of composite, stirring, foaming, cutting and other light foaming insulation materials. The foam hole with a diameter of 1-3 mm is formed inside the concrete to make the concrete lighter and have thermal insulation properties. 1. Fireproof and heat insulation: Foamed cement insulation board is A1 grade non-combustible inorganic material, the fire endurance is more than 3 hours, and no toxic gas will be produced under high temperature or fire. Because of its closed cell ratio of >95%, it has good thermal insulation properties. 2. Good thermal insulation performance: light volume, dry density of 180-250kg / m3; low thermal conductivity, less than 0.06w / mk; low water absorption, less than 8%; is an ideal insulation and insulation material. 3. High compressive strength and strong adhesion: foamed cement insulation board has high compressive strength, greater than 0.5Mpa; system material has good compatibility, and the bond strength with the wall is high; the plate dry shrinkage value is low, no Empty drum cracking; strong wind pressure resistance. 4. Sound insulation performance: Foam cement is a multi-closed hole material, so it is also a good sound insulation material, which can play a good sound insulation effect, reduce the influence of noise and improve the living environment. 5. Life with the building: the system has good stability, high resistance to carbonization, aging and frost resistance, excellent weather resistance, and the same life as the building. At present, the design life of buildings is 50-100 years, and the service life of organic materials is mostly 20-25 years. The secondary construction cost is large, the environmental pollution is large, and it brings inconvenience to people's production and life. 6. Simple construction and short cycle: special mortar is directly bonded, easy to operate, synchronous construction, and greatly shorten the construction period. 7. Energy-saving, environmental protection, and waste: Cement and fly ash are the main raw materials. It will not burn and produce toxic gases under high temperature. It is non-radioactive and belongs to safety and environmental protection products. No harmful gas emissions, no minerals in production, construction and use. The damage caused by flying dust of cotton materials; after the building is scrapped and dismantled, the material can be refilled and utilized after being crushed, which will not pollute the environment and achieve sustainable production. At the same time, as a waste product, it is in line with the national energy conservation and emission reduction industrial policy.
