First, the introduction of A grade foam concrete inorganic insulation board:
Class A fireproof foam concrete insulation board is a new type of fireproof energy-saving material developed by Jixing Industrial Co., Ltd. of Jinan High-tech Development Zone. It has the characteristics of light heat preservation, good durability, combustion performance up to grade A, low carbon environmental protection, energy saving and waste. Comply with the Ministry of Public Security, the Ministry of Housing and Urban-Rural Development, "Interim Provisions on Fire Protection of Exterior Wall Insulation Systems and Exterior Walls for Civil Buildings" (Jongtongzi) [2009] No. 46 and the Ministry of Public Security, "Notice on Clarifying the Relevant Requirements for Fire Supervision and Management of Civil Building Exterior Insulation Materials The requirements of the publication No. 65 of Gongxiao [2011] apply to the external wall insulation and its fire isolation belt, which meets the urgent need for fire safety in the external insulation market. After years of research and development, the technology has gradually matured. With the increase of building fire prevention, this product will gradually be promoted and applied, and become one of the leading products of building insulation in the future.
Second, the performance index of A grade foam concrete inorganic insulation board:
Dry apparent density, kg/m3 200-250
Compressive strength, MPa 0.30-0.80
Thermal conductivity (dry state), W/(mK) 0.050-0.059
Volume water absorption, % ≤ 15%
Combustion performance class A
Note: Before the implementation of the corresponding national standards or industry standards, temporarily test according to JC/T1062-2007 foam concrete block standard.
Third, the main features of A grade foam concrete inorganic insulation board:
(1) The light insulation product has a dry density of 200-250kg/m3 and a thermal conductivity of 0.050-0.059 W/(mK), which has good thermal insulation effect.
(2) Fire safety The main material of this material is inorganic materials such as cement. After testing, the combustion performance reaches Grade A.
(3) Strong bonding force Because the material is a cement-based porous material, it is a homogenous material with mortar and wall surface, good interface affinity, high bonding strength, strong adaptability and high construction efficiency.
(4) Energy-saving and environmental protection, low-carbon and waste, non-toxic and harmless, and can use industrial waste to promote sustainable development.
(5) Durable cement-based closed-cell foaming material has a longer service life than organic insulating materials, and has good resistance to high and low temperature, corrosion resistance, ultraviolet radiation resistance, weather resistance and durability.
Fourth, the main purpose of A grade foam concrete inorganic insulation board:
Fire barrier
The material is mainly used for wall insulation and fireproof isolation belts according to the requirements of “Interim Provisions on Fire Protection of Civil Building Exterior Insulation System and Exterior Wall Decorationâ€.
2. External wall insulation
This material can also be used as an external wall insulation instead of organic materials such as benzene board. Class A fireproof foam concrete insulation board Thin plastering exterior wall insulation system consists of interface mortar, Class A fireproof foam concrete insulation board insulation layer, thin plaster layer and veneer coating, and Class A fireproof foam concrete insulation board is bonded The mortar is fixed on the base layer by a full-stick method, and the thin-faced layer is filled with a glass fiber mesh.
3. Other uses
This product can also be combined with steel structure to form a composite wall panel and ceiling system for the envelope structure of large workshops; it can also be used for sound insulation engineering.
