Why is the fire blanket called an escape blanket?
Fire blankets or escape blankets are fabrics made of glass fiber and other materials that have been specially treated and woven to isolate heat sources and flames. They can be used to extinguish oil pot fires or drown on the body to escape. Cover fire and block air to achieve fire extinguishing purposes.
Main use place
Fire blankets are mainly used for simple initial fire extinguishing tools in enterprises, shopping malls, ships, automobiles, civil buildings and other occasions. Especially suitable for home and hotel kitchens, hotels, entertainment venues, gas stations and other places easy to catch fire. Prevent the spread of fire and protect against escape.
Fire blanket material
The fire blanket is made of fibrous fire-retardant refractory material. Refractory fiber has the characteristics of general fiber, such as soft, elastic, has a certain tensile strength, it can be further processed into a variety of paper, thread, rope, belt, blankets and felt and other products; also has the general fiber does not have High temperature, corrosion resistance. As a fire-resistant insulation material, it has been widely used in metallurgical, chemical, mechanical, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
Fire blanket material classification
Fire-resistant fibers are classified into two major categories: amorphous (glassy) and polycrystalline (crystalline). Amorphous refractory fibers include aluminum silicate, high purity aluminosilicates, chromic aluminosilicates and high alumina refractory fibers. Polycrystalline refractory fibers include mullite fibers, alumina fibers, and zirconia fibers. (Table 1) is also classified according to the maximum allowable operating temperature of the refractory fiber.
Fire blanket material classification properties
Refractory fiber is also a good infrared radiation material, with good thermal capability and infrared heating effect. The use of refractory fiber products can effectively save energy and is an ideal energy-saving and energy-efficiency material. The production practice has proved that the application of fire-resisting fibers in continuous heating industrial furnaces can save energy by more than 15%, and can be used in batch-type industrial furnaces to save energy by more than 30%. At the same time, it can increase productivity and improve product quality, and achieve lighter and larger furnace structures. , comprehensive performance is good. Flame-retardant fiber is soft and elastic, and it is also an ideal sealing material. Due to its insulation, noise reduction, oxidation resistance, oil resistance and water resistance, it is convenient for construction. Therefore, it is widely used in metallurgy, building materials, petroleum, chemical industry, shipbuilding, power, aerospace and other fields.
Polycrystalline fire-resistant fiber is a new type of high-temperature insulation material developed after the amorphous refractory fiber in the early 1970s. It is mainly used in high-temperature furnaces with operating temperatures higher than 1400°C, which can save energy by 25% to 40%. Polycrystalline refractory fiber can also be used as composite reinforcement and catalyst carrier, with good application effect. Polycrystalline refractory fibers can also be applied in the field of aerospace and atomic energy. At present, the polycrystalline refractory fibers that have been industrially produced and applied in the world mainly include polycrystalline alumina fibers (Al2O380% to 90%, SiO221% to 20%) and polycrystalline mullite fibers (Al2O372% to 79%, SiO221%. ～28%) and polycrystalline zirconia fibers (ZrO292%, Y2O38%).
