Cellular lightweight foam cement machine in Russia
Cellular lightweight foam cement produced by cellular lightweight foam cement machine is a new type of fireproof insulation material, also known as fire barrier. It is often used in wall insulation engineering. The wall insulation project is the most superficial layer of the building. It directly bears the adverse effects of wind, fire, rain and snow, winter and summer heat, external force impact, man-made damage and so on. Therefore, the wall insulation engineering technology must have comprehensive performances such as wind resistance, impermeability, fire resistance, frost resistance and heat stress relief. The building wall insulation project is composed of thermal insulation materials and supporting products to form complex engineering structures such as bonding layer, insulation layer, protective layer and decorative layer, and is completed by fine construction of multiple processes. Therefore, the building wall insulation project should be a complete technical system.
The basic principle of the cellular lightweight foam cement produced by the cellular lightweight foam cement machine is to use incombustible cement and a large number of closed pores in the concrete to achieve the effects of fireproofing, lightness and heat preservation. This is a new type of lightweight porous fireproof insulation board made of cement made of foam and foaming agent. After mixed casting, its fireproof performance reaches A1 grade, which is an excellent product of fire barrier.
Performance characteristics of cellular lightweight foam cement produced by cellular lightweight foam cement machine as fire barrier:
1. High-strength multi-inorganic foam material, belonging to Class A1 refractory material, with good fire resistance and refractoriness exceeding 1000 °C. It fully meets the requirements of the fire barrier and the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development [2009] No. 46.
2. High insulation Since the closed cell ratio of the multi-component inorganic foam is > 95%, the high closed cell ratio reduces the convective heat transfer, which is a prerequisite for achieving high thermal insulation. The thermal conductivity of the honeycomb lightweight foam cement fireproof insulation board is the same as that of the polystyrene board, which can meet the needs of building insulation.
3. The strength is better and it is not easy to break. The product has high pressure resistance, flexural strength and strength indicators, and achieves a relatively uniform low density and high strength. It is not easily broken during use and transportation and is fire resistant.
4. Foamed concrete fire barriers are another advantage of this product. When the density is 100-300kg / m3, the fire protection requirements can be fully satisfied, and the cost can be greatly reduced.
5, non-toxic and harmless external wall insulation multi-inorganic cellular lightweight foam cement fire barrier material will not burn at high temperature, will not release toxic gases.
