Insulating Fired Brick with 65% Al2O3 min High Alumina

 

Insulating Fired Brick with 65% Al2O3 min High Alumina is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

This series of High Alumina Insulating Fire Brick are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature.

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: What are the standards for ceramic fiber boards?
Ceramic fiber board currently only GB, and many production enterprises are also in accordance with GB to perform.
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: 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?
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 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?
Distinguishing.Ceramic silicon fiber board by long fiber silica, clay, talc, glaze etc. after 1150 degrees high temperature sintering, twenty-first Century revolutionary high-tech building materials. Characteristics: flexibility, high toughness, high strength, anti wind pressure; with homogeneous magnetized light ceramic surface, disposable, pores, anti pollution, is not easy to dust, mildew, antibacterial, deodorant, anti slip, no static, not fear of chemical erosion, such as acid, alkali, or even sulfate; fire, smoke, high temperature resistance, easy processing, cutting a hole.
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.
