Q:Who knows well about which is better in thermal insulation between aluminum silicate ceramic fiber cotton and asbestos?
Both of them are thermal insulation material. You need to decide on one of them according to the environment you use. If it is to be used for equipment thermal insulation, aluminum silicate fiber cotton is recommended and it’s more convenient in installation. For the two products, the thermal insulation effect varies from the environment in which they are used.
Q:What is nano ceramic fiber board?
Nano ceramic fiber board belongs to nanoscale raw material and uses ceramic fiber as raw materials, and with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., they are used in the environment of high temperature, high pressure and easy abrasion.
Q:What is the standard of ceramic fiber?
The standard of ceramic fiber: Temperature classification: ordinary aluminum silicate fiber board 1100℃, standard aluminum silicate fiber board 1260℃, high purity aluminum silicate fiber board 1260℃, high alumina aluminum silicate fiber board 1360℃ and zirconium containing aluminum silicate fiber board 1430℃.
Q:What's the function of high temperature ceramic fiber blanket?
Ceramic fiber blanket is made from aluminum silicate fiber filament through special double needling technique. Fiber’s intertexture degree, delamination resistance, strength of extension and the surface roughness are greatly improved after the special double needling technique. Ceramic fiber blanket doesn’t contain any organic binder so as to ensure that ceramic fiber blanket has great plasticity and stability in high and low temperature conditions. Typical application: the high-temperature heat insulation of aerospace, steel and petrochemical; fire protection and heat insulation of military equipment; heat insulation of industrial furnace, wall lining and backing lining of heating devices; heat insulation of high temperature devices; heat insulation of high temperature pipes; thermal insulation and fireproofing of electronic components; high-temperature gasket and raw materials of module and folded pieces.
Q:What is the performance of ceramic fiber tube furnace?
The performance of ceramic fiber tube furnace is fairly good and its raw material is ceramic fiber. Ceramic fiber is a fibrous and light fireproof material with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., thus being widely used in such industries as machinery, metallurgy, chemical industry, petroleum, ship, electronics and light industry. And it becomes increasingly widely used in top science and technology departments, like aviation and atomic energy, and full of development prospect.
Q:What are the specifications of ceramic fiber blanket?
Specifications of ceramic fiber blanket: 15,000x610/1220x10mm, 14,400x610/1220x12.5mm, 7200x610/1220x20mm, 7200x610/1220x25mm, 5000x610/1220x30mm, 4000x610/1220x40mm, 3000x610/1220x50mm.
Q:What’s the price of refractory ceramic fiber blanket?
Ceramic fiber refractory thread throwing blanket is 4000 yuan per ton. Ceramic fiber refractory insulation module is 4700 yuan per ton. Ceramic fiber board refractory insulation board is 7000 yuan per ton. These are good.
Q:How to keep ceramic fiber board?
Ceramic fiber laminated board belongs to high temperature resistant fiber board technology, and especially involves ceramic fiber board technology. It is made by using ceramic fiber as material. Its feature lies in that ceramic fiber is first made into ceramic fiber paper. 1. Multilayer ceramic fiber papers are stacked, pressurized and made into board. Binder layer is set every two layers of ceramic fiber paper one. 2. The thickness of the ceramic fiber paper one is 0.2-1.0mm. The thickness of binder layer is 2 0.5-3.0mm. The fiber diameter of ceramic fiber raw material is 1-5μm and the fiber length is 10-100mm. Ceramic fiber laminated board made by using the practical new program, has high density, strong tensile and impact resistant capability, good friction resistance performance, and certain flexibility, which is especially suitable for the sealing of the high temperature parts, the repair of furnace gaps, the backing lining of refractory materials, etc.
Q:What is the use of ceramic fiber rope?
Ceramic fiber rope is interweaved with quality ceramic fiber. It is widely used in chemical industry, electricity, paper-making, food, pharmacy, etc., as well as sealing of furnace door, high temperature &pressure engine, pump and valve. And it is applicable to various medium, such as clean fluid or slurry, saline water, emulsion, oil, hydrocarbon, solvent, paper pulp, etc.
Q:What is the material of ceramic fiber?
1、Ceramic fiber, ceramic fiber felt for short, is a fireproof material (such as flint clay) owing to resistance to high temperature. The fibrous substance, formed from being melt by electric arc and then blew up by compressed air, is called as ceramic fiber cotton. 2、Ceramic fiber cotton can be made into a variety of ceramic fiber products. The ceramic fiber cotton content of domestic ceramic fiber felt AI2O3 is 62% and 45%. The former one can be used in the temperature of 1150-2000℃ while the latter is in 1000℃.
