Q:How much pressure can the ceramic fiber board withstand?
Ceramic fiber fireproof plate, the density of 350-400Kg/m ceramic fiber board, fand; density above fand 400Kg/m.
Q:What are the standards for ceramic fiber boards?
The existing ceramic fiber board has broken through the age of fear of water, and the newly developed hydrophobic ceramic fiber board has the characteristics of normal working under the water environment.
Q:What are the uses of ceramic fiber boards?
Ceramic fiber board is the main use of heat insulation, fire protection, insulation to use, but also with sound absorption, noise reduction, thermal shock resistance and so on. Ceramic fiber board is mainly used in all kinds of furnace lining insulation, kiln wall lining insulation, metallurgical industry furnace fire, aluminum reduction tank, refractory brick backing.
Q:What are the differences between nano ceramic plate and ceramic fiber board?
Ceramic fiber board is a kind of ceramic fiber cotton produced by injection technology. It is made by continuous production and advanced technological production line.
Q:What method should be used to measure the thermal conductivity of fiberboard?
Fiber board thermal conductivity of ceramic fiber board thermal conductivity information is mainly: ceramic fiber board thermal conductivity, thermal conductivity of ceramic fiber board price, thermal conductivity of ceramic fiber board wholesale, thermal conductivity of ceramic fiber board factory, discusses the protection method of hot plate test principle and method of MDF thermal conductivity and its relation with temperature; and analyzed the test error.
Q:What is the difference between ceramic fiber board and nano ceramic fiber board?
The nano ceramic fiber board through the introduction of nanotechnology, the special production process, product performance has been greatly improved, high strength, low thermal conductivity, good heat insulation performance, energy saving effect is obvious, which improves the safety of the furnace, and in high temperature and high pressure conditions, can also play a good performance the product.
Q:Refractory insulation board, pressure plate, nano heat transfer plate, calcium silicate board and ceramic fiber board?
Ceramic fiber boardCeramic fiber board product categories:1260 standard ceramic fiber board sygx-264 1260 high purity ceramic fiber board sygx-3641400 zirconium ceramic fiber board sygx-564 1400 high alumina ceramic fiber fire plate sygx-464D1400 zirconium ceramic fiber fire baffle sygx-564D
Q:Ceramic fiber plate and aluminium silicate plate are chosen as lining materials
Volume density is low: the density of the ceramic fiber lining is about 25% of the lining of the light heat insulation brick, about 10% of the lining of the light pouring material; adopting the fiber lining can greatly reduce the steel structure load of the furnace and prolong the service life of the furnace lining.
Q:What are the sound-absorbing fiber boards?
The theory on the absorption coefficient is the best sound-absorbing board sound-absorbing effect 1 (all suck, no reflections), but in reality, this material does not exist (black holes in the universe are the sound absorption coefficient is 1, which is completely absorbed)
Q:What are the specifications of the ceramic fiber board?
Ceramic fiber board, also known as aluminum silicate or refractory fiber, including ceramic fiber blanket, ceramic fiber, ceramic fiber fireproof plate (plate).
