I. Introduction
Due to the dry climate, abundant vegetation and frequent wildfires in Los Angeles, the need for fireproof materials is extremely urgent. As a new type of fireproof material, synthetic woven straw mat has been widely used in various places in Los Angeles, which effectively improves the fire safety of the region, so it is of great practical significance to carry out in-depth research on it.
Second, the material composition of fireproof synthetic woven straw mat
(1) Basic fiber materials
Fire resistant synthetic woven straw mat mainly uses special synthetic fibers, such as aramid fiber. Aramid fiber has high strength, high modulus, high temperature resistance, chemical corrosion resistance and other excellent properties. It will not melt and drip at high temperature, but form a carbonized layer, continue to play a role in heat insulation protection, and provide the basic fire protection for the straw mat.
(2) fireproof additives
In the process of making the straw mat, a variety of fireproof additives are added, such as aluminum hydroxide, zinc borate and so on. When the aluminum hydroxide is heated, it will decompose and absorb heat, release crystal water, and play the role of cooling and extinguishing; Zinc borate can form a glassy isolation layer on the surface of the material to prevent the transfer of oxygen and heat, and further enhance the fire resistance of the straw mat.
Three, fire performance characteristics
(1) High temperature resistance
After experimental tests, the fire resistant synthetic woven straw mat can withstand high temperature environment up to 800℃, under the continuous high temperature action, the structure of the straw mat can still remain relatively stable, will not burn or disintegrate quickly, for the fire to fight for more evacuation and fire time.
(2) Flame retardant performance
The straw mat has excellent flame retardant properties, according to the relevant standards for vertical combustion test, its burning speed is extremely slow, and after the fire source is removed, it can quickly self-extinguish, and will not spread burning. This makes it effective in preventing the spread of fire in practical use.
(3) Heat insulation performance
Good thermal insulation is another major feature of the straw mat. At the fire scene, it can effectively block the transfer of heat, reduce the temperature rise rate of the surrounding environment, and protect the surrounding objects and personnel from high temperature damage.
4. R&d background
The Los Angeles area is frequently hit by wildfires, and traditional fireproofing materials have certain limitations when dealing with complex fire conditions. For example, ordinary straw MATS are flammable and cannot play an effective protective role in the initial stage of a fire; Although some fireproof materials have certain fireproof performance, they are not good in terms of high temperature resistance and durability. In order to meet the growing demand for fire protection, the research and development of a new type of fire resistant synthetic woven straw mat has become a top priority. Relevant scientific research institutions and enterprises invested a lot of resources, after continuous testing and improvement, and finally successfully developed a fire-resistant synthetic woven straw mat suitable for the Los Angeles area.
5. Practical application
(1) Outdoor public areas
In the outdoor public areas such as parks and squares in Los Angeles, fire-resistant synthetic woven grass MATS are laid on the green isolation belt and the perimeter of walking paths. When a wildfire occurs, these MATS can form a fire barrier to prevent the fire from spreading to surrounding buildings and crowded areas, ensuring the safety of public areas.
(2) The perimeter of the building
Fire-resistant synthetic woven MATS are also placed around the perimeter of many buildings, especially those located in mountainous areas or areas at high risk of fire. Straw MATS can not only prevent wildfires from directly igniting buildings, but also protect the basic structure of buildings from high temperature damage to a certain extent, providing important support for fire protection of buildings.
(3) temporary places of refuge
In temporary shelters, fire-resistant synthetic woven straw MATS are used as floor laying materials. It can not only provide a relatively safe rest environment for refuge personnel, but also play a role in fire insulation in the event of a fire to ensure the safety of refuge places.
Vi. Conclusion
Los Angeles fire-resistant synthetic woven straw mat with its unique material composition and excellent fire performance, has played an important role in the local fire safety field. From the perspective of research and development, it is an innovation in response to the special fire environment in the Los Angeles area. In practical applications, it is widely used in outdoor public areas, surrounding buildings and temporary shelters and other scenes, effectively improving the fire prevention ability of the region. With the continuous progress of technology, it is believed that the fire-resistant synthetic woven straw mat will be further optimized and expanded in the material properties and application range, providing a strong guarantee for the fire safety of more areas. Future research can focus on further improving the environmental performance of straw MATS and reducing production costs to achieve better economic and social benefits.
