- Q: What are the standards for ceramic fiber boards?
- Ceramic fiber board is made of continuous production, water production line and advanced technology, ceramic fiber board produced with smooth surface, accurate size, good toughness, can be arbitrarily cut, good insulation effect and other performance characteristics.
- 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: Refractory insulation board, pressure plate, nano heat transfer plate, calcium silicate board and ceramic fiber board, which is good?
- 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: What are the sound-absorbing fiber boards?
- Ordinary materials have sound-absorbing effect, just how much difference. And when it comes to sound-absorbing board, we are only sound-absorbing coefficient of more than 0.3 of the material known as sound-absorbing material.
- Q: What is the difference between ceramic fiber board and nano ceramic fiber board?
- The traditional ceramic fiber board has good heat insulation, high temperature resistance to certain characteristics, widely used in kiln products, but this tradition also has some shortages, low intensity, high temperature and high pressure, there are restrictions on the application of kiln stress.
- 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: 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 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: 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: 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.
