Q:What is the feature of ceramic fiber washer?
Here follows the product features: 1) Continuous use temperature can reach 1000℃ while short time using temperature is up to 1260℃. 2) It is highly resistant to acid-base corrosion and erosion of molten metal (eg. aluminum and zinc). 3).It is good in high temperature strength and thermal insulation properties (please refer to physical and chemical indicators.) 4) It is better in electricity insulation than glass fiber. 5) It is non-toxic, harmless and odourless.
Q:What is the thickness of ceramic fiber paper?
The thinnest is 0.5mm while the thickest is 3mm. Fiber paper is a kind of solid insulated material in electrical engineering, including plant fiber paper and synthetic fiber paper, which are made by being soaked in insulation liquid or varnish or glue. Using ceramic fiber as the principle raw material, ceramic fiber paper is made by wet forming process. With even thickness, smooth surface and good flexibility, the ceramic fiber paper can be processed into products of various sizes via being sheared or punched.
Q:What is the price of ceramic fiber fire-resistant cloth?
The common specification and model of ceramic fiber cloth: 1.5-6mm, general thickness: 1m, including nickel chromium alloy wire reinforced, stainless steel wire reinforced, glass fiber reinforced, ceramic fiber coating cloth, ceramic fiber slag cloth, ceramic fiber sintering cloth, ceramic fiber fumigation cloth. The price of ceramic fiber fireproof cloth is 5 yuan/m2.
Q:What is the difference of ceramic fiber asbestos cloth?
Ceramic fiber cloth is resistant to high temperature and heat shock, low in heat conductivity coefficient and heat capacity; excellent high temperature insulation performance and long service life; able to resist the erosion of non-ferrous metal like aluminum and zinc; excellent low and high temperature strength. It is made from asbestos cotton. Owing to its noninflammability, once on fire, it can erase dirt on the cloth.
Q:What is the difference between nanometer ceramic board and ceramic fiber board?
Ceramic silicon fiber board, made by burning long fiber silicon dioxide, clay, talcum powder and colored glaze under 1150 degree, is a revolutionary high-tech building material in the 21st century. Ceramic fiber board, also called aluminum silicate fiber board, is a kind of refractory material. It still keeps good mechanical strength even after heating. Compared with fiber blanket and fiber felt, it is rigid and a fiber thermal insulation product with supporting strength.
Q:What’s the price of refractory ceramic fiber blanket?
The price of ceramic fiber blanket varies from place to place. It is advised to have a look at local market.
Q:What are the specifications and models of the ceramic fiber board?
It’s refractory material and can keep good mechanical strength even after heating. Compared with fiber blankets and felts, it is thermal insulation product with rigidity and supporting strength. Its making principle adopts injection fiber (which is short, fine, and easy to smash).
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:What’s the maximum bearing temperature of the refractory and high temperature resistant ceramic fiber cotton?
It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
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. Ceramic fiber blanket doesn’t contain any organic binder so as to ensure that ceramic fiber blanket has great plasticity and stability in high and low temperature conditions.
