flame-retardant cryogenic insulation paper

Flame-retardant cryogenic insulation paper(compatibility with oxygen) :

The flame-retardant cryogenic insulation paper is made of super-thin glass wool, which is produced in all -electrical kiln with blaze technology, by a peculiar manufactory process. The insulation paper is often composited with aluminum foil as a thermal insulation material for using in the vacuum jackets of storage and transportation vessels for cryogenic liquids(Liquid Hydrogen liquid oxygen, LNG, liquid Helium, liquid Nitrogen and liquid Argon).Its advantage are flame-retardant at open fire and with the best thermal insulation characteristic(lower thermal conductivity, higher contact thermal resistance),low outgassing rate, light weight, high uniformity and wide range of the application temperature:-269°C-800°C

Q: What is the density of natural gas: Under normal temperature and atmospheric pressure, the density of methane is 0.7174kg/m3, the relative density is 0.5548.The density of natural gas is generally 0.75 kg/m3 ~ 0.8kg/m3, the relative density is generally from 0.58 to 0.62.The density of natural gas is related to the temperature, pressure and the composition of natural gas. Under normal circumstances, the density of the natural gas varies from 0.55 to 0.90kg / m3.The relative density of natural gas is the ratio of the density of natural gas to the density of air under the standard state (0, 101.325kPa)

Q: Why should the city's natural gas?: For easy to be discovered, and then eliminate the leakage, the need for no smell of natural gas smell.

Q: What is the difference between the cooker and the gas cooker: The biggest difference is that the induction cooker is the use of high-frequency magnetic field generated by the eddy current in the magnetic field on the bottom of the pot to produce heat, so the cooker must be made of magnetic metal. The gas pot is directly heated by fire, so it does not need to be guided.

Q: Pipeline natural gas will not cause gas poisoning?: Liquefied petroleum gas (LPG) is a by-product of refinery catalytic cracking and thermal cracking.The main components of the catalytic cracking gas are as follows: (5) hydrogen, methane, ethane, ethylene, ethylene oxide, ethylene oxide, ethylene oxide, ethylene oxide, 10 ~ 6, ethylene, ethane, ethylene, propylene, ethylene glycol, ethylene glycol, ethylene oxide, ethylene oxide, ethylene, gas and water, the main components of the gas are as follows: (42) to hydrogen, methane, ethane, ethylene, ethylene oxide, ethylene oxide, ethylene, ethylene oxide, ethylene and propylene, the methane is from 5 to 5, ethane to ethylene, ethylene, ethylene oxide, ethylene and propylene, which is from 3 to 3, propane to propylene by ~ ~ ~ (s), propylene from 16 to 20, propylene from 6 to 11, butane from ~ (c) to ~ 46, butene from ~ (5) to about 6.The main components of the thermal cracking gas are as follows: (7): hydrogen, methane, 5 ~ ~ (s), ethane ~ ~ ~ ~ 7, ethylene, ethylene glycol, ethylene oxide, propylene glycol, propylene oxide, propylene glycol, propylene glycol, ethylene glycol, 5 to 18, propane, propylene, propylene glycol, propylene glycol, propylene glycol, 7 to 8, butane, butene, 4 to 5, containing more than 5 carbon atoms of hydrocarbons from 2 to ~ 0.2 ~ (3) ~ ~ ~ ~ ~ ~ ~ ~ (12). These hydrocarbons are easily liquefied, they are compressed to only the original volume of 1/250 ~ l/33, stored in the high pressure resistant steel tank, the valve open gas tank when used in flammable hydrocarbons gas goes through a pipe into the burner. After the formation of a light blue flame, combustion process produces a lot of heat (calorific value is about 92100 kJ/m3 ~ 121400 kJ/m3).The calorific value of the three gases: liquefied gas is the highest, followed by natural gas, city gas is lower. The use of these three kinds of gas stove is not the same, can not be directly used interchangeably.

Q: Bought a few gas, a person with only less than 2 months on the end of the bath, do not cook to eat, I feel very strange, I would like to ask a bottle full of gas is the weight of how much?: If users find bottled gas Duanjinqueliang, can reflect the complaints to the quality inspection department. In addition, taking into account the safety issues such as air pressure, inflation can not be exceeded, with a maximum of 14.9 kg.

Q: The working principle of the gas refrigerator?: The ammonia is absorbed by dilute ammonia water and becomes a concentrated ammonia solution. So coalThe utility model is characterized in that the air refrigerator is heated by gas combustion, and the three substances of ammonia, water and hydrogen can be recycled in the pipelineMinimum temperature of minus 40 degrees C.

Q: Car burning natural gas has no effect on the car,,: Three point oneThe decrease of inflation coefficient is an important reason for the decline of the power of natural gas vehicle. However, the decline in the coefficient of gas is determined by the nature of the gas itself, from the fuel is clearly unable to solve this problem, the only solution is to take the intake boost measures. However, the increase in air intake will undoubtedly increase the size and quality of the engine, there are some difficulties in the implementation.

Q: How many cubic meters of gas does a ton of steam boiler produce a ton of steam: First of all we need to know about 1 tons of water into steam to absorb heat, and the heat value of natural gas combustion to release heat, the boiler equipment, passed to the changes of water absorption of heat medium water, physical properties, low temperature and high temperature water into water into steam gasification, it completes the process need to absorb the heat of about 600 thousand kcal natural gas quality.

Q: Liquefied gas and coal gas _?: Both of them are gas fuels, but they are not the same thing.Coal gas is made from coal. The main components of gas are carbon monoxide, hydrogen and methane. After the gas was born in the gas plant, it was stored in a large gas tank, and then ran down the gas pipe to your home. Therefore, only in the place where there is a gas plant, the laying of the gas pipeline in place, it is possible to use gas.

Q: How much gas is equal to 1: 1 kg liquefied petroleum gas is approximately equal to 460L, that is, the 0.46 party; about 1 kg of natural gas is equal to 740L (according to the density of 12T), that is, the 0.74 party; therefore, the equivalent of about 1 kg liquefied natural gas.
