Q:Who can introduce how to use ceramic fiber binder?
Method: 1、Stir 1) Pour drinking water into mixing barrel, and then pour cementing agent orderly according to amount, and the mixing ratio is: water: dry powder 1:4. Then stir it evenly with a motor stirrer (750W) and the speed is 150r/min. 2、After watering it (placing it still) for 15 minutes, stir it again for 1-3 minutes.
Q:What is the thickness of ceramic fiber paper?
The density of ceramic fiber board is 280-320kg/m3. Ceramic fiber board is made by wet vacuum forming process, whose strength is higher than that of fiber blanket and vacuum forming felt. And it can be applied in such high temperature field that requires products with rigid strength. Here follows its features: high compressive strength and long service life; low thermal capacity and conductivity; non-brittle material and good flexibility; accurate size and good flatness; easy to cut, install and work; high resistance to weather; continuous production, uniform distribution of fiber, and stable performance; excellent sound-absorption and noise reduction.
Q:What are the ceramic fiber products?
Ceramic fiber is produced by double needling technique and is widely used in high and low temperature environment. According to the different manufacturing technique used in market, ceramic fiber blanket is usually divided into two kinds. One is thread throwing blanket, and the other is injection fiber. 1. The diameter of the fiber filaments: Thread throwing fiber is much coarser. Thread throwing fiber is generally 3.0-5.0;micro;m; Injection fiber is generally 2.0-3.0;micro;ml. 2. Fiber length: Thread throwing fiber is much longer. Thread throwing fiber is generally 150-250mm. Injection fiber is generally 100-200mm. 3. Coefficient of thermal conductivity: Injection blanket is superior to thread throwing blanket because of its thin fiber. 4. Tensile and flexural strength: Thread throwing blanket is superior to injection blanket because of its coarse fiber. 5. Application of making ceramic fiber block: It is superior to injection blanket because the fiber of thread throwing blanket is much coarser and longer. Injection fiber blanket is easy to be broken and torn during the process of block production folding, while thread throwing fiber blanket can be tightly folded and cannot be easy to damage. The quality of the block will directly affect the quality of the lining. 6. The vertical layer spread application of large pieces of blankets such as heat recovery boiler: Thread throwing blanket has better tensile resistance and is more durable due to its coarse and long fiber filament, so thread throwing blanket is superior to injection blanket.
Q:What is the difference between ceramic fiber insulated cotton and aluminum silicate cotton?
They are thermal insulated materials. You should decide to use which one according to the using environment. Aluminum silicate fiber cotton is suggested to be used in equipment insulation. In different using environment, their thermal insulation effect will be different. Ceramic fiber blanket is also called as aluminum silicate fiber blanket and aluminum silicate acupuncture blanket, and the main material is aluminum silicate fiber cotton. Considering the pure thermal insulation effect, ceramic fiber blanket is better than aluminum silicate insulation cotton. The reason is that ceramic fiber blanket is formed by double needle process from aluminum silicate cotton, which greatly increases its intertexture degree, resistance to lamination as well as tensile strength and flatness. Fiber blanket contains no organic binder/binding agent to assure its plasticity and stability in the environment of high and low temperature.
Q:What is the difference between nanometer ceramic board and ceramic fiber board?
The difference between nanometer ceramic fiber board and ceramic fiber board is as follows: The traditional ceramic fiber board with good heat insulation and high temperature resistance is widely applied in some furnaces, but some deficiencies, such as low strength, still exist in this kind of traditional products, which restricts its application in furnaces with high temperature, high pressure and stress. However, product performance is greatly improved with the introduction of nanotechnology and the use of special manufacturing technique. It has high strength, low thermal conductivity, good thermal insulation performance, obvious energy saving effect, which can improve the safety of furnace and develop performance of the product under the condition of high temperature and high pressure.
Q:Is high density ceramic fiber board environmentally friendly?
Density board is also called fiberboard. It is artificial plate made from raw material of wood fibers or other plant fibers adding urea formaldehyde resin or other applicable binders. According to the difference of density, it can be classified into three types: high density board, medium density board and low density board. Soft, impact resistant and easy to reprocess, density board is a kind of good material for furniture producing at abroad.
Q:What’s the density of ceramic fiber board?
The density of fiberboard by wet molding process is 280-320kg/m3. The smaller one is called ceramic fiber felt in national standard, and its maximum density can be up to around 700 kg/m3.
Q:What is the material of ceramic fiber?
Ceramic fiber is a fibrous and light fireproof material with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., thus being widely used in such industry as machinery, metallurgy, chemical industry, petroleum, ceramic, glass, electronics, etc.
Q:What are the specifications of ceramic fiber thermal insulation pipe?
Technical performance unit: Kg/m technical capacity: 345-60 heat conductivity coefficient: W/m.k0.016-0.024 using temperature: -90-+120℃
Q:What’s the difference between the ceramic fiber and glass fiber?
Glass fiber is a kind of inorganic nonmetallic material with great varieties. It has the advantages of good insulation, strong heat resistance, excellent corrosion resistance and high mechanical strength. But brittleness and poor abrasion resistance are its defects. As a category of the glass fiber, glass wool is a kind of manmade inorganic fiber. As a result of fibrosis of the molten glass, cotton shaped material, glass wool, whose chemical composition is glass, is formed. As inorganic fiber, it’s characterized with good shape, small volume density, low thermal conductivity, thermal insulation, sound absorption, corrosion resistance and stable chemical properties. Ceramic fiber blanket is also called alumina silicate fiber blanket. One of its main components is alumina, and alumina is the major component of porcelain, so it’s called ceramic fiber.
