Q:What is the essential difference between the standard of ceramic fiber and ordinary aluminium silicate?
However, insulating bricks and refractory fibers can not be abused at will. So far as the basic oxygen furnace, cement rotary kiln lining, due to the high temperature chemical erosion, temporarily cannot be used for lining fiber. Ceramic fiber products (aluminum silicate fiber products) for continuous heating equipment such as ceramic tunnel kiln, has already achieved by ceramic fiber products (aluminum silicate fiber products) for continuous heating equipment lining, according to relevant reports, quickly push board kiln and tunnel kiln in the energy saving effect of fire resistant ceramic fibers are very significant. In particular, ultra high temperature heating, such as burning temperature in 1538 to 1649 degrees of furnace, the use of refractory fiber energy saving effect is best. Ceramic fiber products (aluminum silicate fiber products) at present, Europe and the United States and Japan all ceramic kiln equipment using ceramic fiber products (aluminum silicate fiber products) lining. Not long ago, Japan will be decomposed into compartments such as gas tunnel kiln structure, and then to the segmented manufacturing factory construction site assembly, all of this is due to the use of ceramic fiber material, greatly saves the cost of more convenient because of the kiln. The research on energy saving effect of ceramic fiber products is also being carried out from the aspects of material modification. Ceramic fiber products (aluminium silicate fiber products)
Q:Do fiberglass or ceramic fiber paper have insulation effect?
Glass fiber has low temperature resistance, preferably not higher than 550 degrees, and ceramic fiber has good temperature resistance.
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:What's the function of refractory ceramic fiber band?
Ceramic fiber belt main uses: industrial heat insulation, pipe and cable insulation coating, exhaust pipe insulation coating, flange connection, heat radiation shielding, high temperature furnace door curtain, etc..
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: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 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.
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?
1, appearance. Ceramic fiber cloth (HLGX-208A1/HLGX-208A1) ceramic fiber yarn textile woven by warp and woof formed with grid, the grid was bigger; the ceramic fiber paper (HLGX-236) vacuum suction molding, there is no grid.2 density. Ceramic fiber paper density 200Kg/m ceramic fiber cloth density fand, 500Kg/m fand, ceramic fiber paper than ceramic fiber cloth density.3, thickness. Ceramic fiber paper, the thinnest can do 0.5mm, the thickest 10mm, ceramic fiber cloth thickness is limited, in general the thinnest also have 2mm, the thickest 5mm.
