High Purity Alumina Papers Ceramic Fibers

The ceramic fiber are manufactured from high purity raw material alumina powder ,silica sand for the high temperature grades and zircon sand is also used. The ceramic mixture is heated in an high temperature electric furnace and the stream of molten material is drawn into fibers by either spinning or blowing .It is produced by advanced “blown” and “spun” processes .Ceramic fiber bulk shows a high temperature stability ,low weight and heat capacity and an outstanding sound absorption is complemented by their resistance to oxidation and reduction

Excellent thermal and chemical stability

Low thermal conductivity and heat storage

Excellent thermal shock resistance and sound –absorption capability

No bonding agent and corrosive substance

Asbestos free

Q:What fiber glass made of ceramic fiber paper?: Ceramic fiber paper production process is:Beat out - pulp - pulp - long mesh forming - vacuum dehydration - drying - cutting - winding - packaging

Q:Are ceramic fiber paper permeable?: Ceramic fiber paper is said to be paper, in fact, is relatively large density, but still cotton like, it is permeableCeramic fiber composite board is able to play a certain waterproof effect

Q:The difference between the ceramic fiber blanket and rock cotton blanket?: Refractory ceramic fiber material is a lightweight and efficient thermal insulation material. It has the following advantages over traditional heat insulation materials:Ceramic fiber as lining, low volume density: ceramic fiber lining than light heat insulation brick lining light more than 75%, lighter than light castable lining light 90% to 95%. If using fiber lining, it can greatly reduce the steel structure load and prolong the service life of the furnace.

Q:Is the slag ball of the ceramic fiber useful?: Slag balls are basically useless, just like raw ore.

Q:What can I do to get the clothes off the ceramic fiber?: Clean white, white socksWhite clothes on the stubborn stains are difficult to eradicate, this time to take a lemon slice, boil water, put the white clothes soaked in water, about 15 minutes after the wash can be.

Q:Which is the best insulation effect of ceramic fiber paper and XPE insulation film?: The insulation effect depends on the temperature. The same material, the temperature is different, thermal conductivity is not the same. At low temperatures, I suggest you use XPE. Ceramic fiber paper is generally used for hundreds of degrees or even thousands of degrees of high temperature.

Q: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)

Q:Expert answer. What is the difference between ceramic fiber paper and ceramic fiber cloth?: Ceramic fiber cloth is made of heat-resistant gold wire or non alkali glass yarn reinforced spun wire ceramic fiber yarn. The ceramic fiber cloth has high strength, good flexibility and processability. It not only has high temperature insulation property, but also has the flexibility of ordinary textile. Fire retardant clothing, fire blankets, insulation and other industrial and civilian fire insulation products.

Q:Can ceramic fibers be spun into fibers, please?: The utility model can also achieve higher strength by increasing metal wire reinforcement, and finally can be made into products such as yarn, cloth, belt, rope, packing, etc., and the utility model has wide application.

Q:What's the difference between ceramic fiber paper gasket and ceramic fiber gasket?: Density: ceramic fiber paper gasket HLGX-200DP and ceramic fiber cloth pad HLGX-500DP, the difference is different: the density of the ceramic fiber paper gasket density of 200Kg/m ceramic fiber cloth pad fand, density 500Kg/m fand around.
