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:Why doesn't the insulation effect of ceramic fiber compound reflect the insulation board well?

Tianjin solid composite reflective insulation board, he has one of the biggest advantages of long-term high temperature, the use of chemical stability, and can be used for a long time.

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:Is the slag ball of the ceramic fiber useful?

There's not much use value, the only effect is recycled to reduce waste, prevent pollution two.

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: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.

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: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:What is ceramic fiber paper? What is ceramic fiber paper for?

In order to understand what ceramic fiber paper can do, it is necessary to know what product characteristics it has. Only by knowing these advantages can we make accurate judgments about what we can do.The ceramic fiber paper is made of ceramic fiber, so the ceramic fiber paper itself contains no asbestos and can replace the carcinogenic asbestos products on the market.The raw material of the ceramic fiber paper is longer, low density, high strength, and has a certain elasticity, so it is easy to carry out stamping, cutting, winding and other construction operations. It is because of the ceramic fiber paper after high temperature firing process, so it has high temperature resistance, chemical corrosion, thermal shock, low thermal conductivity, good dielectric strength and high elastic modulus and high performance.

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.
