Where is the best packing area for ceramic fibers?
As the temperature continues to rise, the products will gradually become white, organic fiber has been completely carbonized products completely for the high temperature inorganic ceramic fiber resistant ceramic fiber (standard type) white maximum temperature ceramic fiber cloth content index color 1260 C fiber diameter 1-4 m thermal shrinkage (1232 C, 24h) 3.5% transmission rate (at 538 8pcf) three 0.130w/m.k two aluminum oxide content 45-48% 0.7-1.2% ferric oxide content of calcium oxide and sodium oxide content of 0.43% slag ball content <8.5% breakdown voltage 5 kv/mm resistance of 5 * 1010 ohm 3w.xxceramic content index white color thickness 1.5mm--6.0mm single 0.5 3kg/ square meters of organic fiber content <20% content <2% strengthening materials alkali glass fiber nichrome wire (1Cr18Ni9Ti)
Compared with asbestos textiles, ceramic fiber textiles have the following advantages:1) the continuous use temperature can reach 1000 DEG C, and the service temperature can reach 1260 DEG C for a short time.2) has good acid and alkali corrosion resistance and aluminum, zinc and other molten metal melting ability.3) good high temperature strength and heat insulation performance (refer to physical and chemical indexes).4) ceramic fiber cloth, band, packing and other products with non alkali glass fiber yarn as strengthening material have higher insulation and high temperature electrical insulation than glass fiber.5) non-toxic, harmless and odorless.
