Hebei foamed cement supplier
Foamed cement insulation board production process:(Chemistry) method with physical foaming agent were prepared in aqueous solution into foam, the foam added to the cement based materials, aggregate, admixture, additive and water into slurry, through mixing, pouring, curing and thermal insulation boardPerformance indexClass-A fireproof cement foam insulation performance of plateItemTechnical performanceDry apparent density, kg/mCompressive strength, MPa0.100.250.400.500.80Thermal conductivity (dry), W/ (m · K)0.0450.0490.0530.0550.060Volume water absorption rate,%8%Drying shrinkage value, mm/m0.80Carbonation coefficient0.80The softening coefficient0.80Combustion performanceA-class non-combustibleThe best use of temperature1100 ℃Main features:1, a fire, high durability, building energy efficiency can reach more than 65%.2, light thermal insulation. Dry density of 120 ¬ - 199kg/m3, heat conduction coefficient in 0.045-0.060 W/ (m • K).3, early strength, high strength. Using ordinary portland cement foam, dry density of 176kg/m3 products, 1 days strength of 0.2 MPa, 28 days strength 0.4MPa, technical performance in the same industry leading level.The formation of numerous independent bubble 4, noise cause porous, so the sound absorption effect than common concrete was about 5 times higher than 45dB, sound insulation coefficient.5, convenient construction, high work efficiency, convenient construction, short construction period, construction without sand, cement and other materials, material stacking is simple, efficient, small size, less occupied space equipment and other resources, no building rubbish, after the completion of construction without plastering. The traditional masonry construction need 12 people 60 minutes, with foam cement board only 3 people can be done in 60 minutes, saving labor costs.6, the compressive strength, strong adhesive force.Main uses:1 fireproof isolation beltFoamed cement insulating board high durability, a fire, building energy efficiency can reach more than 65%, in accordance with the Ministry of public security, Ministry of construction "external wall insulation system and the civil decorative fireproof Interim Provisions" (the public and pass the word) (2009) 46, and the elimination of the [2011]65 document, which can be used for fireproof isolation belt of exterior wall external insulation.Fire protection design of isolation belt requirements"Civil building exterior insulation and exterior wall decorative fireproof Interim Provisions" (the public and pass the word [20009] No. 46)Non curtain wallResidential buildingHeight, MClassification for burning behavior of insulating materialETICSOther civil construction24No less than B2When using B2, each layer isolation belt24 ≤ h < 60No less than B2When using B2, every 2 layers set fire barrier60 ≤ h < 100No less than B2When using B2, each layer isolation belt100AWithout fireproof isolation belt24 ≤ h < 50A, B1When using B1, every 2 layers set fire barrier50AWithout fireproof isolation beltA, B1When using B1, each layer of isolation
