Advantages of class a fireproofing material insulation board
1. High fire resistance; NLC inorganic thermal insulation board is inorganic material, which belongs to grade A fire protection material. Then it has excellent fire resistance, and the fire resistance reaches over 1000 C, which completely satisfies the fire resistance requirements of external wall thermal insulation board.
2. High heat preservation and insulation; NLC inorganic insulation board has a closed porosity of more than 95%. High closed porosity makes the heat transfer of air flow low, which is a prerequisite for high heat insulation. Therefore, the thermal conductivity of the exterior wall thermal insulation board is 0.045-0.068W/m.k, which is slightly lower than that of the polyphenyl board, but its application effect in practical projects is basically appropriate, which can satisfy the needs of building thermal insulation.
3. The strength is relatively good, not easy to break; the NLC inorganic insulation board produced by our company has high compressive and flexural strength, reaching a relatively uniform of low density and high strength. It is not easy to break in operation and transportation, and conforms to fire-resistant integrity.
4. quality light adhesive strength is high, light quality is another advantage of our products. The density is between 150 and 300kg/m3, which can meet the requirements of the external insulation board and reduce the cost. The compatibility of the data is good, and the cohesive force is strong with the wall.
5. Non-toxic, harmless, environmentally friendly and energy-saving; NLC inorganic thermal insulation board is based on cement and fly ash as the primary raw materials. It does not burn at high temperature and does not release toxic gases. It is attributed to safety and environmental protection inion, and it is supported by the national industrial policy as a waste product.
6., the number of years of life is long; the current design and construction life of our country is generally 50 to 100 years. The design life of organic insulation data is mostly 20 to 25 years. That is to say, the insulation layer and construction life can not be kept in sync. This means that the ageing resistance of organic thermal insulation materials makes it necessary for a building to carry out at least 2-4 times of thermal insulation construction during its service. This kind of repeated construction operation has resulted in direct damage to the construction itself. The construction period has been shortened, and the construction of repeated insulation has also brought serious inconvenience to people's lives. The life span of NLC inorganic insulation board is more than 50 years, and it can be the same as the building.
In view of the shortcomings of the existing building thermal insulation materials, especially the rigid porous inorganic thermal insulation materials, our company provides a kind of practical data with renewed structure, better comprehensive performance (bulk density, thermal conductivity, strength, sound absorption and insulation effect, bonding strength, etc.) NLC inorganic thermal insulation board (foamed cement board), which is more suitable for repair. The application of building wall insulation in traffic noise reduction has really satisfied the urgent need for new building insulation materials for energy conservation in China. It also has the characteristics of fireproofing, heat insulation, life saving with buildings, environmental protection and so on.
