Around 6:50 p.m. Paris time on April 15, 2019, a serious fire broke out in Notre Dame de Paris, a famous French building. The fire was so fierce that the spire collapsed and almost all the wooden frames of Notre Dame de Paris burned down. Notre Dame in Paris is once again a wake-up call to us. Can fires be avoided through effective measures? The main structure of Notre Dame in Paris is "saved" and the main structure is intact. The main structure of the lower part of Notre Dame in Paris is composed of stone walls, which are generally not easy to catch fire. The Church of Notre Dame in Paris has thousands of ancient timber roofs, half of which can be traced back to 1147, which is also the main reason for the collapse of the spire and the difficulty of controlling the fire.
For modern high-rise buildings, fire protection infrastructure is an important means to prevent fire, not only that, we also need to recognize the importance of the application of A1 class fire prevention and insulation materials. In addition to the building materials used, such as cement, steel, glass, etc., which have flame retardant effect, there are also flame retardants added to the materials, which are coated on the surface of various materials that need fire protection. It can ensure that they are not burned when igniting, and will not make the burning range intensified or expanded.
Fire retardant material is a kind of protective material. It can prevent combustion but it is not easy to burn.
Nowadays, the application of flame retardant technology and flame retardant materials is not limited to the construction industry, but widely used in all walks of life. Flame retardant materials are used in autos, electronic appliances, wires and cables, switch sockets, seat fabrics, etc. At present, the main flame retardant materials are organic and inorganic, halogen and non-halogen. Organic flame retardants are some of the flame retardants represented by bromine, nitrogen and their compounds. Inorganic flame retardants are mainly antimony trioxide, magnesium hydroxide, aluminium hydroxide, silicon and other flame retardant systems. Halogen-free flame retardant is a kind of flame retardant material with rapid development.
Okay, today the wonderful content brought by A1 class fire-proof and thermal insulation materials is introduced to you here. I hope that our explanation will be helpful to you all! Our official website is: ! Thank you for your support!
