- 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 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.
- 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: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: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 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 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: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: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.
