Fire Retardants
The importance of using fire retardant coatings for commercial, office and residential towers, banks and multi-storey car parks is one of the characteristics of modern civilization, to protect citizens from the dangers of fire and fire. Experience has shown that the costs of fire are 30-100 times the cost of fireproofing a project. Therefore, the use of these coatings is especially important in metropolitan cities. Tehran, Mashhad, etc. are increasing. Need to use fireproof coating: In the event of a fire in towers and parking lots, within 10-15 minutes the temperature will reach the yield point of the structure and the structure will not be able to bear the load and will eventually collapse. According to the ASTME-119 standard, the critical temperature of columns is 538°C and for beams is 598°C. If fireproof coating is used, the metal structure will have a fire resistance of 1-3 hours, depending on the thickness of the applied coating. justify;"> Mineral-based fireproof coating (Cement mortar) : These coatings are based on gypsum or cement. The ingredients of this type of coating are cement plasters, including Portland, which are lightened using minerals such as vermiculite and perlite. Applications of mineral-based fireproof coating: Protection time of the structure: Depends on the type and shape of the structure, sheet thickness, number of floors of the structure, type of use (office - commercial - residential), flammable materials, type of possible fire and distance from the fire station
