New fire insulation materials advantages
2018-12-12 15:59:32

Among the organic thermal insulation materials, polystyrene foam and polyurethane foam are the most representative, and the most common in building insulation engineering applications. Foam concrete block bricks are a new type of inorganic fireproof insulation material, which has obvious advantages compared with these organic insulation materials. These advantages determine the necessity of replacing the organic insulation with foam concrete blocks.


  The foam concrete block is made of cement as the main material. It is a safety material. The refractory grade is more than 2 hours and can reach the Class A fireproof standard, which can fully meet the fireproof conditions of any building. Building insulation with foam concrete will not cause fire at all. The greater advantage is that the block brick insulation wall material developed by Guangzhou Oufu Building Materials can completely cover the steel structure in the block and defend the steel structure. Even if a fire breaks out, the steel structure is not easy to deform and collapse. Managed the fire protection problem of steel structure and played the role of double fire prevention.


  The foam concrete block has a durability of more than 50 years, and can be used for the same life as the building. The one-time insulation construction can keep the building insulated for life and avoid the shortage of multiple insulation construction. The foam concrete roof insulation layer in Heilongjiang and other places in China is a project that was guided by the experts of the former Soviet Union in the early 1950s. It has been intact for nearly 60 years and is still in use. This has fully proved the durability of foam concrete. Under the premise of standard construction, the service life of high-quality foam concrete can be up to 100 years, and it is also used for key construction projects.


  In addition, due to the poor combination of the external thermal insulation material and the wall of the organic external wall, engineering accidents such as cracking and falling off are often caused, which not only makes the durability of the project unguaranteed, but also the falling of the falling object poses a serious threat to people. Foamed concrete can be used as a wall material, and it has good self-insulation properties, and there is no problem of the outer insulation layer falling off. A small part of the external wall insulation is used, mostly anchored or dry hanging, not easy to fall off, and very few use paste. Since the foam concrete and the wall are made of the same material, the bonding is very firm and not easy to fall off.


  Foamed concrete becomes an excellent sound insulation material when the closed cell ratio is greater than 90. Guangzhou Oufu has completely mastered the technology of producing partition wall panels with foam concrete, and the partition wall panel has a significant effect on the sound separation of indoor walls.


  Under the general direction of the country's advocacy of green building materials, after the comprehensive implementation of the restrictions on the use of clay products in the urban areas of the 12th Five-Year Plan and the prohibition of the use of solid clay bricks in the county, the new wall material industry has attracted new development opportunities to promote the application of energy-saving waste. New technologies and new products for new wall materials are conducive to promoting energy saving and consumption reduction in the construction industry.
