Fire blanket

Fire blankets, also known as fire blankets, fire extinguishing blankets, fireproof blankets, fire blankets, flame-retardant blankets, and escape blankets, are fabrics made from materials such as glass fibers through special treatment and weaving. They can isolate heat sources and flames and can be used to put out oil pan fires or worn over the body for escape.

Fire extinguishing principle:

Cover the fire source and block the air to achieve the purpose of extinguishing the fire.

Fire blanket material:

Material Classification

Refractory fibers are classified into two major categories: amorphous (glassy) and polycrystalline (crystalline). Amorphous refractory fibers, including aluminosilicate, high-purity aluminosilicate, chromium-containing aluminosilicate and high-alumina refractory fibers. Polycrystalline refractory fibers, including mullite fibers, alumina fibers and zirconia fibers. (Table 1) There are also classifications based on the maximum allowable service temperature of refractory fibers.

Material classification characteristics

Refractory fibers are also excellent infrared radiation materials, featuring good thermal capacity and infrared heating effects. The use of refractory fiber products can effectively save energy and is an ideal energy-saving and efficiency improvement material. Production practice has proved that the application of refractory fiber in continuous heating industrial furnaces can save energy by more than 15%, and in intermittent industrial heating furnaces, it can save energy by more than 30%. At the same time, it can increase productivity and improve product quality, achieve lightweight and large-scale furnace structure, and have good comprehensive performance. Refractory fibers are soft, elastic and ideal sealing materials. Due to their insulation, noise reduction, oxidation resistance, oil resistance and water resistance, as well as their convenient construction, they are widely used in metallurgy, building materials, petroleum, chemical industry, shipping, power, aerospace and other fields.

Polycrystalline refractory fiber is a new type of high-temperature heat insulation material developed in the early 1970s after amorphous refractory fiber. It is mainly used in high-temperature kilns with working temperatures above 1400℃ and can save energy by 25% to 40%. Polycrystalline fire-resistant fibers can also be used as composite reinforcing materials and catalyst carriers, with good application effects. Polycrystalline refractory fibers can also be applied in the fields of aerospace missiles and atomic energy. At present, The polycrystalline refractory fibers that have been industrially produced and applied internationally mainly include polycrystalline alumina fibers (al2o3 80% - 90%, sio2 21% - 20%) and polycrystalline mullite fibers (al2o3 72% - 79%, sio2 21% - 28%). And polycrystalline zirconia fibers (ZrO292%,Y2038%), etc.
