Product Description:

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:Do fiberglass or ceramic fiber paper have insulation effect?
Glass fiber cotton bar, there are more air inside, the effect may be better
Q:Ceramic fiber insulation moisture-proof, but also play a cooling effect?
Fiber cotton can be further processed into fiber blanket, board, paper, cloth, rope and other products.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:Ceramic fiber spray and thrown silk floss, which is better?
1, fiber diameter: rejection fiber more coarse, rejection filament fiber is generally 3.0-5.0 mu m, spinneret fiber is generally 2.0-3.0 mu m;2, the length of fiber yarn: rejection fiber longer, the rejection of silk fiber is generally 150-250mm, spinneret fiber is generally 100-200mm;3, the coefficient of thermal conductivity: spray cotton fiber is lower than that of the thrown silk;4, the tensile and flexural strength: thrown silk because fiber thicker than that of spraying cotton;
Q:What are the materials for making ceramic fibers?
The main raw material for the production of ceramic fiber cotton is mainly three two aluminum oxide, and silicon dioxide production process through the silk process, Wuhan, Kyrgyzstan rnd-digital ceramic fiber and ceramic foam with instructions on
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:Why is there no direct relationship between thermal conductivity and conductivity of ceramics?
The concept of electrical conductivity in physics, in which the product of the quantity and the electric field intensity is equal to the conduction current density. For isotropic media, conductivity is scalar; for anisotropic media, conductivity is tensor. In ecology, conductivity is the ability to conduct current by means of a numerically expressed solution. The unit is expressed in SIEMENS per meter (S/m). The conductivity is simply the product of the measured conductivity (G) and the conductance cell constant (L/A). Here the L is the length of the liquid column between two plates and the A is the area of the plate. P l=l/ = sigma (1) definition or explanation for the reciprocal of resistivity conductivity. Sigma Rho =1/ (2): units in the international system of units, the conductivity of the unit is SIEMENS / m. (3) the physical meaning of conductivity is to indicate the conductivity of a substance.
Q:Which insulation effect is better compared with ceramic fiber for STP insulation board?
But the use of different temperature, nano microporous insulation materials used in 1000 DEG, 1600 DEG C high temperature resistant ceramic fiber.
Q:Carbon fiber and aluminum alloy material in the end what is the difference?
The advantages of carbon fiber are light, excellent corrosion resistance, good elasticity and outstanding vibration absorption effect. The disadvantage is that the shock resistance is poor and the high temperature resistance is poor. It is used in a lot of planes, boats, sporting goods, such as bicycles, tennis rackets and so on. But the price is much more expensive than aluminum alloy.
Q:Why doesn't the insulation effect of ceramic fiber compound reflect the insulation board well?
And although the ceramic fiber high temperature resistance, but in 1400 degrees when the use of life will be greatly reduced, and the thermal conductivity of the beginning as compound reflection insulation board, high temperature is higher than the compound reflection insulation board greatly.
Q:Expert answer. What is the difference between ceramic fiber paper and ceramic fiber cloth?
Ceramic fiber paper is made from high purity ceramic fiber and a small amount of binding agents which are scientifically selected and tightly controlled. The wet vacuum forming process makes the fiber distribution very uniform, and the thickness and volume density of the aluminosilicate fiber paper can be strictly controlled. The binder will be completely ablated during use.
