- 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 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: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 differences between nano ceramic plate and ceramic fiber board?
- The biggest difference between the two is that:1, the coefficient of thermal conductivity is different, the nano ceramic plate is about three times of the ordinary ceramic fiber board2, temperature class is not the same, nano ceramic board maximum temperature of 1050 degrees, ceramic fiber board should be 1400 degrees temperature.3, the range of applications is different. Nano ceramic plate is mainly used in high, fine and sharp technical fields, and has strict requirements on thermal conductivity. Ceramic fiber boards are widely used and can be used wherever there is flame or temperature.
- Q:What are the specifications of the ceramic fiber board?
- Ceramic fiber board density in conventional 300-350Kg/m over 350Kg/m to fand, fand fireproof plate series.
- Q:Refractory insulation board, pressure plate, nano heat transfer plate, calcium silicate board and ceramic fiber board, which is good?
- Sheng Yang series of ceramic fiber board is based on the traditional process of comprehensive upgrading of the excellent vacuum forming insulation materials, slag ball content of less than 3%, fiber distribution uniformity, internal and external strength consistent, size controllable.Ceramic fiber board is made by spraying superfine ceramic fiber through water washing, slag removal, fiber freezing and vacuum forming. The product has superior high temperature resistance, excellent rigidity and toughness.
- Q:Is there any difference between ceramic silicon fiber board and ceramic fiber board?
- 1, high compressive strength, long service life; 2, low heat capacity, low thermal conductivity;3, non brittle material, good toughness;4, accurate size, good flatness;5 、 easy to cut and install, easy to construct;6, excellent wind erosion resistance;7 、 continuous production, uniform distribution of fiber, stable performance.
- Q:What method should be used to measure the thermal conductivity of fiberboard?
- It is concluded that the test error of this method and device is about 2%. This filament ultra light aluminum silicate fiber product: the filament ultra light aluminum silicate product is by Shandong Zibo high quality burnt precious stone as raw material, passes through the smelting furnace, the rejection silk, blows the cotton, the auxiliary mold and so on to deliver the work procedure. Therefore, the thermal conductivity of fiberboard is chosen by heat flow meter method.
- 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 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.
