I. Introduction KH foam insulation board, also known as A-level concrete: Concrete foam board, fireproof insulation board, foam cement board, fireproof insulation board, composite foam cement board, wall fire insulation panels. The product is to be national "civil external wall insulation systems and fire Interim Provisions" and the introduction, the basic principle is the use of cement and concrete in a large number of non-combustible closed pores to fire, light, thermal insulation effect. Prepared with foam foam and cement mixing castable, after curing light made of a porous inorganic cement-based Class A insulation board has good insulation properties, A-level non-combustible and other characteristics, in line with the "civil outer facade insulation systems and fire Interim Provisions "requirements. For wall insulation and fire buffer zone, to meet the exterior insulation market exigencies. Technology has matured, with the building fire intensified efforts to promote the product will be gradually applied, and become one of the leading products for building insulation. Second, the performance indicators in Table 1 foam concrete fireproof insulation board Performance Indicators Project type Ⅰ Ⅱ type dry bulk density, kg/m3 125-180 200-250 Compressive strength, MPa 0.10-0.25 0.30-0.80 thermal conductivity (dry), W / (m · K) 0.045-0.049 0.05-0.059 Water Absorption,% ≤ 20.0% ≤ 12.5% ??combustion performance of Class A non-combustible Class A noncombustible three main features: 1, A-class fire, high durability, energy saving of up to 65%. 2, cost-effective, affordable. 3, lightweight insulation. Product dry density 120? -250 Kg / m3, thermal conductivity 0.045-0.060 W / (m? K). 4, high strength. Using ordinary portland cement foam, the technical performance of the same industry-leading level. 5, strong bonding. Concrete foam insulation board for the cement-based materials, and construction of the main wall material compatibility, good affinity bonding firm, not falling, 6, convenient construction, concrete foam insulation board can be pasted or hanging construction, can be used for external wall insulation , exterior insulation, roof insulation can also be used across the seven, green, non-toxic, pollution-free, pollution-free, and can make use of industrial waste, energy-saving benefits of waste, to achieve national "building energy-saving rate of 65%," the eight, durable is good, there is no problem of aging, and buildings with life. 9, to create a variety of insulation systems, can be pasted, can hanging, applicable to all climate zones. 10, the product thickness and size can be customized according to customer requirements. 11, the earliest design and manufacture of special cutting Moulder companies. 12, new construction technology to create foam board, series construction technology to fill the domestic blank. 13, in line with the public through the word [2009] No. 46, and public consumption [2011] No. 65 document requirements, build new energy-saving fire protection system to meet the market need. Four, fire insulation board performance and current market categories insulation board detailed comparison: Category Eps Xps extruded polystyrene board insulation board perlite board panels polyurethane wool board BW-A-class fire insulation board Thermal conductivity W / mk 0.045 0.034 0.026 0.065 0.054 0.058 Compressive strength Mpa 0.2 0.44 0.34 0.40 dry density kg/m3 18-22 24-25 60 240 130 180 combustion performance level B2 Class B2 Class B2 Class B2 Class A Class A1 Water absorption V / V% Low Low Low High very low resistance to melt refining very good very good very good very good limited radioactive Pass Pass Pass Pass Pass Pass weather resistance aging Yi Yi Yi aging aging aging is not easy to aging better than complicated construction situation is more complicated than the fan is relatively complex compared to English simple and useful life 15 years 20 years 25 years 30 years 50 years comprehensive appraisal insulation effect is good, but off the aging flammable insulation effect is good, but flammable, off the aging insulation works best, but easy to burn the insulation effect is poor, and easily weathered shed insulation effect is good, easy to absorb water, damp difficult construction project cost high moisturizing effect, non-flammable, non-aging, overall economic efficiency is best, easiest 15136665900 0377-60653331 construction
