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: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, also known as aluminum silicate or refractory fiber, including ceramic fiber blanket, ceramic fiber, ceramic fiber fireproof plate (plate).
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 are the differences between nano ceramic plate and ceramic fiber board?
Nano ceramic plate for ceramic fiber with insulating board (felt), it is a functional material with excellent properties of aerogel insulation material and has a heat shielding function, adaptation to adhesive and a variety of inorganic elements in high temperature ceramic fiber as reinforcing material, through a special process preparation.
Q:What are the uses of ceramic fiber boards?
The ceramic fiber board, also called aluminum silicate fiber board or refractory fiber board, is divided into five grades according to the temperature grade:Fire dragon type ceramic fiber board HLGX-164Fire dragon standard ceramic fiber board HLGX-264Fire dragon high purity ceramic fiber board HLGX-364The dragon of high alumina ceramic fiber board HLGX-464Fire dragon contains zirconium type ceramic fiber board HLGX-564
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:How much pressure can the ceramic fiber board withstand?
Ceramic fiber board divided by density, can be divided into ceramic fiber, ceramic fiber board density 250-260Kg/m fand; density, fand 300-350Kg/m;
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.
