Q:Who knows the density of ceramic fiber board?
The density of ceramic fiber board is 280-320 kg/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:How is the quality of ceramic fiber vermiculite cloth?
The quality of ceramic fiber vermiculite cloth is good, and its advantages are as follows: high temperature resistance, low thermal conductivity, thermal shock resistance, low thermal capacity; excellent heat insulation performance, long service life; resistant to erosion of nonferrous metals such as aluminum and zinc, etc.; good low and high temperature strength; non-toxic, harmless, and no adverse effect on environment.
Q:What are the specifications of ceramic fiber thermal insulation pipe?
ф22mm ф27mm ф34mm ф42mm ф48mm ф60mm ф76mm ф89mm ф114mm ф140mm ф168mm ф219mm ф273mm ф325mm ф377mm ф426mm ф480mm ф530mm ф630m All of these specifications belongs to the international standard pipe diameter. Thermal insulation pipe is used for the transportation of liquid, gas and other medium. And it is often used in the pipe thermal insulation projects in petroleum, chemical industry, military, central heating, central air-conditioner, and municipal administration, etc.
Q:What is ceramic fiber blanket?
Ceramic fiber blanket is made from aluminum silicate fiber filament through special double needling technique. Fiber’s intertexture degree, delamination resistance, strength of extension and the surface roughness are greatly improved after the special double needling technique.
Q:What’s the density of ceramic fiber board?
The density of ceramic fiber board is 280-320kg/m3. Made by adopting wet process and vacuum forming techniques, the ceramic fiber board is higher in strength than the fiber blanket and vacuum forming felt, and it applies to high temperature fields with requirement on rigidity and strength of products. The ceramic fiber board has high compression strength and long service life, low thermal capacity and heat conductivity, non-brittle material quality and good toughness, accurate dimension and good flatness, easy cutting and installation, and good anti-wind erosion properties. With continuous production and uniform distribution of fibers, it has stable performance and fine sound absorption and noise reduction properties.
Q:Ceramic fiber insulation after moisture can still play a cold roles?
Ceramic fiber is an efficient insulation material, with light weight, high strength, low oxidation resistance, low thermal conductivity, good flexibility, corrosion resistance, low heat capacity and sound insulation and so on.
Q:Who knows well about the production process of the ceramic fiber?
Ceramic fiber, a type of fibrous lightweight refractory, possesses so many advantages as light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical shock resistance. 1. Diameter of cellosilk: thread throwing fiber is thicker and its diameter is usually within the range of 3.0-5.0μm, while the injection silk fiber is usually 2.0-3.0μm; 2. Length of cellosilk: thread throwing fiber is longer and its length is usually within the range of 150-250mm, while the injection silk fiber is usually 100-200mm; 3. Thermal conductivity: the injection silk blanket is better than the thread throwing blanket for the former has finer fiber; 4. In terms of tensile strength and fracture resistance, the thread throwing blanket is superior to the injection silk blanket for the former has thicker fiber.
Q:How many kinds of materials are there in ceramics?
According to the performance of the heating furnace and the ceramic fiber felt the temperature of the furnace wall heat surface layer can be made of hard ceramic fiber felt products size 00 x 00 x 0 (10) follows the basic properties of MM ceramic fiber blanket: (L) the use of high temperature to l000 degrees. (Tao Xianzhan) the density is below 00Kgm (usually 10kgm), only light, heat resistant lining L - 1. () the heat capacity is only 1 of the light heat resisting lining and the light fireclay brick. (ceramic fiber) at high temperature, volume stability, residual shrinkage is very small, without leaving contraction or expansion joints, construction convenience. () small thermal conductivity. On the hot surface temperature of 00 degrees Celsius (average temperature) guide coefficient of 0.0W (M. K); 00 (the average temperature is 1 DEG C) to O.0W (m.k); 1100 C (average temperature c) to 0.1W (m.k), about lightweight clay brick, 1 light at the 110 heat resistant lining. () sound insulation effect is good. The ceramic fiber coating can reduce the high-frequency noise of frequency less than 1000Hz, and can also absorb some low-frequency noise (()) with a certain tensile strength. () good chemical stability. () elasticity is good (at room temperature, elasticity%), easy to transport and install. (10) it has better resistance to airflow erosion, and can withstand 0 - 0ms airflow erosion.
Q:Ceramic fiber blanket afraid of water?
The conventional ceramic fiber blanket is afraid of the water, because the ceramic fiber blanket has very strong water absorption, water absorption ratio of 1:10, when the ceramic fiber blanket after the water will become a conductor, the heat transfer effect and water, ceramic fiber blanket thermal insulation function lose all.
Q:Aluminium silicate fiber blanket for insulated pipes or aluminium silicate ceramic fiber paper?
The heat preservation of the pipe is usually made of aluminium silicate fiber blanket. The heat preservation of the base is made of aluminium silicate ceramic fiber paper. The insulation of the pipe is very little.
