FAQ

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.
Do ceramic fiber paper smell at high temperature?
Ceramic fiber paper is made from high purity ceramic fibers, with a small amount of scientifically selected and tightly controlled binders, and binders will evaporate during use. If the ceramic fiber paper in a high temperature environment, the bond will gradually volatile, volatile initial will have a certain odor, and so volatile, there will be no flavor. The binder is a series of organic rubber, and the smell remains as little as possible.
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.
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
What can I do to get the clothes off the ceramic fiber?
Remove pen marks from clothes easilyFirst of all, the alcohol evenly sprinkled on the pen printed on the pen, alcohol should be used at a concentration of not less than 75% of the alcohol used in medicine. Remember to put on this side of the garment that has been poured down. Do not touch other surfaces of the garment. Otherwise, the color of the pen may be stained with other parts of the garment.Prepare most of the water, and then pour two full bottle of bleach water in the water, stirring, and a little washing powder, so that the laundry powder can be fully dissolved in water. Soak your clothes completely in water for twenty minutes. Washing clothes, there is no mark!Clothes stained with pens, ball pen marks, there is another way to solve: that is, do not rush to the clothes into the water, but first wash with gasoline, washed parts of the re wash.
Do fiberglass or ceramic fiber paper have insulation effect?
Second, in the case of temperature can be met, glass fiber cotton insulation better. The main advantage of ceramic fiber is to make gaskets and the like.
What is ceramic fiber paper? What is ceramic fiber paper for?
The manufacture of ceramic fiber paper was originally made of minerals! The production process is as follows: the ore is melted at high temperature, then the ceramic fiber is made by throwing the yarn, and finally, a lightweight insulating refractory material is made by wet forming process.
How to paste the ceramic fiber paper on the iron plate?
Not used in high temperature industry, then with double-sided adhesive can be.
