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:How high is the temperature resistance of the ceramic fiber gasket?
- Generally divided into standard type and high profile, the standard temperature of 1260 degrees to 1000 degrees of long-term use of high alumina long-term use of 1200 degrees.
- Q:How to paste the ceramic fiber paper on the iron plate?
- Not used in high temperature industry, then with double-sided adhesive can be.
- Q:Why is there no direct relationship between thermal conductivity and conductivity of ceramics?
- The advanced production technology enables the fiber to distribute very evenly, and the paper thickness and bulk density can also be strictly controlled. Ceramic fibers have very low thermal conductivity. The thermal conductivity of ceramic fiber paper was measured by thermal flow method.
- Q:The difference between the ceramic fiber blanket and rock cotton blanket?
- The heat capacity (heat storage capacity) of ceramic fiber lining is low: the heat capacity of ceramic fiber is only about l/10 of light heat resistant lining and light castable lining, and the heat capacity of lining material is proportional to the weight of lining. Low heat capacity means the furnace in the reciprocating operation absorb less heat and heating speed, greatly reducing the operational control of the temperature in energy consumption, especially for heating furnace and furnace, furnace shutdown has obvious energy saving effect.
- Q:The difference between ceramic fiber cloth and ceramic fiber paper?
- 1. appearance. The ceramic fiber cloth has an obvious grid like appearance, and the ceramic fiber paper is very few or even mesh like.2. density. The density of ceramic fiber paper is greater than that of ceramic fiber cloth.3. thickness. Ceramic fiber paper, the thinnest can do 0.5mm, ceramic fiber paper can not do so thin, generally thin, there are also 2mm.4. stand erect. Ceramic fiber paper can be like in our life that can be placed on the A4 paper, mold, stand up. Ceramic fiber cloth is like the fabric used in our 5. lives. It's soft and doesn't stand upright.6. tear resistance. The toughness of the ceramic fiber paper is not as good as that of the ceramic fiber cloth.
- Q:Is everybody ceramic fiber cotton poisonous?
- Depends on the production process is the above kind, the province may not, but the production process may have some problems.
- Q:Where is the best packing area for ceramic fibers?
- 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.
- Q:What's the fire resistance of the ceramic fiber?
- Because of the low heat conductivity, small density and light weight of the fiber, the light steel support structure is adopted in the design and construction of the kiln, which makes the development of the ceramic kiln into the lightweight era of the kiln. The fiber has small heat storage and is suitable for quick heating and cooling firing. Flexible fibers can be processed into products with grooves or openings, and has good resistance to mechanical shock and impact ability, chemical stability is good, these advantages for the development of new kiln, and spread to the development of ceramic industry, have an important role in promoting. The ceramic fiber products are: carpet, blanket, block, a variety of products like fiber, dispersion of fiber paper and vacuum forming, the work is generally in the range of 8711427 DEG C, under special circumstances can be short-term use in the high temperature limit temperature above the.
- Q:The condition of ceramic glass fiber at high temperature
- Generally, glass fibers can be pulled long and cut short when required. However, ceramics are difficult to control and difficult to grow because of technological conditions;
- Q:Can ceramic fibers be spun into fibers, please?
- TolerableToday's ceramic fiber fabrics are rope, cloth, tape, yarn, clothing, etc.
