Q:Refractory insulation board, pressure plate, nano heat transfer plate, calcium silicate board and ceramic fiber board?
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: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:Ceramic fiber plate and aluminium silicate plate are chosen as lining materials
Ceramic fiber board is of high quality ceramic fiber cotton with low slag ball content as raw material, using specific pulp and mixing equipment, ensure the cutting length and the concentration uniformity of cotton fiber, using international advanced vacuum molding technology and international advanced processing technology, the product not only has excellent mechanical strength and precise geometry the size, and maintains the excellent properties of fibrous insulation materials, can be substituted for calcium silicate board also requires tough, self-supporting and refractory insulation field.
Q:What are the specifications of the ceramic fiber board?
Ceramic fiber board common specifications are: 600*400, 900*600, 1000*600 and 1000*1200mm, thickness 10/20/25/30/40/50mm, thinnest can do 6mm.Depending on the temperature range, it can be divided into:Common ceramic fiber board HLGX-164Standard ceramic fiber board HLGX-264High purity ceramic fiber board HLGX-364High alumina ceramic fiber board HLGX-464Ceramic fiber board containing zirconium HLGX-564
Q:What are the sound-absorbing fiber boards?
Sound-absorbing material:1, itself has sound-absorbing properties, porous fiber material.2, does not have sound-absorbing material, but processed into sound absorption structure.Common sound-absorbing materials are: polyester fiber sound-absorbing board, trough wood sound absorption board, hole wood sound-absorbing board, recycled wood sound-absorbing board, the latest is Dr. sound, high temperature ceramic sound-absorbing board, a fire prevention, water quality, hard environmental protection
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: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: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 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.
