Refractory Fiber Products Short And Simple
Refractory fiber castable according to the construction method can be divided into different coating materials, casting materials, spray paint. Mainly by the fiber needle blanket as raw material by adding inorganic binder, expansion agent, inorganic curing agent and a variety of additives made. Refractory Fiber Products Its main performance is a low thermal conductivity, strong thermal stability, a certain pressure strength, a certain anti-air erosion ability, a certain resistance to mechanical vibration, integrity, construction is simple and rapid clean, Maintenance and repair is simple, oven time is short and simple, long service life.
Refractory fiber is now widely used in all walks of life, according to the different requirements, the product of the physical and chemical properties and installation methods are also very different. Its products are classified as follows: According to the material can be divided into standard (1260 type), Refractory Fiber Products zirconium type (1425 type), chromium type (1425 type), and polycrystalline alumina type (1600 type). According to the shape can be divided into fiber cotton, fiber blanket, fiberboard, Refractory Fiber Products fiber mat, fiber folding block, components and fiber paper, rope, cloth and so on.
At present, the resistance method of injection fiber, dry needle punching blanket and resistance method rejection silk fiber, dry needle punching blanket is still the international fire-resistant fiber production of two typical process technology. As the application of refractory fiber is expanding, Refractory Fiber Products and with the development of high-tech, fire-resistant fiber products to the functional direction of development to meet the specific areas of the required functional products, such as the product has excellent high temperature Performance, Refractory Fiber Products mechanical and mechanical properties, flexibility and spinnability.
In the manufacturing method, the melting method and the chemical method (colloid method) coexist and simultaneously develop to meet the needs of different varieties of use.
(1) melting method, commonly used in the production of amorphous (glassy) fiber (small cross-sectional area, short fiber production), its low technical content, low production costs, Refractory Fiber Products a wide range of products widely used, mainly for industrial kilns Furnace, heating device refractory, insulation applications in the field of basic materials.
(2) chemical method for the production of polycrystalline fiber, the method of high technological content, high production costs, high added value, Refractory Fiber Products but the product is still less. Mainly used for high temperature industrial furnace above 1300 ℃ fire insulation and aerospace, aviation, Refractory Fiber Products nuclear energy and other cutting-edge technology to enhance the body material.
