Construction Technology of Fire Resistant Fibre Products
Fire retardant fiber products are the most important material for fire safety engineering. It relies on its high temperature resistant fiber and fiber treatment to form composite materials with excellent flame retardant, heat insulation, sound insulation, and moisture insulation properties, and has become a very popular building material. It is widely used in home building materials, office buildings, railway subway, public places, ships and automotive interiors, etc. However, in order to achieve the excellent performance of this type of fire-resistant fiber product, correct construction technology is essential.
The first point of construction is to choose the appropriate fire-resistant fiber products according to its different materials and different application scenarios. Generally speaking, flame retardant fibers made of aluminum-magnesium alloy or carbon composite material, which have high temperature resistance, will be the best choice. For the general building these materials can meet the need.
Second, the fire-resistant fiber product is generally composed of several components, including the base layer, the intermediate layer and the surface layer. The base layer is the most important part. It will directly affect the performance and service life of the fire-resistant fiber products. Therefore, correct methods must be adopted for the construction of the base layer. For example, the base layer should be heated and softened in the early stage, so that the fiberglass and resin can be fully absorbed by the substrate, and the contact between the fiberglass surface layer and the substrate can be improved. In addition, the geotechnical measures related to the base layer should also be considered. For example, the surface treatment of the base layer should be adopted to reduce the dihedral angle and make the surface smooth. At the same time, expansion joints should be considered to prevent the fire-resistant fiber product from cracking due to thermal expansion and contraction.
The third construction point is that the intermediate layer and the surface layer of the fire-resistant fiber product must be installed correctly and combined firmly together. For example, it is necessary to pay attention to the selection of the appropriate primer for the surface of the fire-resistant fiber product. In addition, it is also necessary to pay attention to the installation of the surface material, such as the selection of the appropriate tools, the small tolerance and the even construction thickness. This is to ensure that the fire-resistant fiber product will obtain good flatness, verticality and uniform adhesion, and it can also reduce the labor cost and construction time.
The fourth construction point is to pay attention to the maintenance of the fire-resistant fiber product during the construction process. For example, pay attention to the protection of the surface of the fire-resistant fiber product during construction. If necessary, the necessary protection measures should be taken. At the same time, it is also necessary to pay attention to the laboratory test, especially within the safety requirements, to ensure that the fire-resistant fiber products can meet the national standard requirements and obtain the certification of national safety products.
In summary, in the construction of fire-resistant fiber products, the selection of materials, the construction method of the base layer, the combination of the intermediate layer and the surface layer, the maintenance of the construction and the laboratory test procedures are all important. Therefore, the parties should pay attention to the fire-resistant fiber products must select the best materials and adopt the correct construction technology in order to obtain excellent performance and safety performance.
