aluminosilicate refractory fiber paper for lng cryogenic storage

The ordinary cryogenic insulation paper(incompatibility with oxygen):

Ordinary cryogenic insulation paper is made of a special process with high quality chemical fiber, usually compositely used with aluminum foil or single (double)aluminized polyester film. It is used in the storage container of cryogenic liquid(liquid helium, liquid nitrogen and liquid argon) and also used in dry ice storage vessels. Its advantage are lightweight, good uniformity, low thermal conductivity, large thermal contact resistance, low outgassing rate in vacuum. This product can be applied in a wide temperature range:-269°C-190°C.

Q: How many cubic metres of gas is a ton of coal: Calorific value of coal by 5100 kcal /kg, natural gas of 8500 kcal / cubic,A ton of coal is approximately equal to 5100*1000/8500=600 cubic meters of natural gas

Q: Is natural gas solid?If so, under what conditions will become solid?: When it comes to energy, people think of coal, oil, or natural gas, and seldom think of the crystal clear ice". However, since 1960s, people have been in the tundra and the depths of the ocean to find a burning ice". This "combustible ice" in geology is called natural gas hydrate (Natural Gas Hydrate Gas, referred to as Hydrate), also known as the "clathrate" (Clathrate), molecular formula: CH4 - nH2O, it has been confirmed that the molecular structure of CH4 - 8H2O.

Q: Does the electronic ignition gas stove need the battery?If the battery needs to be replaced?If you do not need a battery, that is what the principle of ignition, has been able to use it?: With the kind of flameout protection with two batteries (fire cover with two needles), battery power consumption is larger, not durable, the general battery in March to about 6 monthsOn the fire cover with one ignition needle without flameout protection, with a battery, will be relatively more durable for 6 months to 1 years, when the ignition needle can make fire can not continuously "Da Da" ignition, electric strength is obviously insufficient, then it is difficult to ignite the fire source to replace the battery.

Q: Is the gas escaping from the pipe floating up or down?: Because the main component of natural gas is methane (CH4), the relative atomic mass of C is 12, and the relative atomic mass of H is about 1

Q: Now there are a lot of users in the home are used artificial gas stoves and water heaters, and now to be replaced by natural gas, how should change, what components are needed, what tools are needed: Artificial gas water heaters, stoves to change the natural gas need to change the main nozzle.Because artificial gas and natural gas pressure is not the same, artificial gas into the home pressure is not greater than 0.02MPa, natural gas into the home pressure is not greater than 0.0035MPa.

Q: What gas is natural gas?: Basic introduction: from the broad definition of natural gas, natural gas refers to all exist in nature, including all kinds of natural gas of the atmosphere, hydrosphere, biosphere and lithosphere formation. The definition of "natural gas", which has been used for a long time, is a narrow definition from the point of view of energy. The natural gas mainly exists in the oil field gas, the gas field gas, the coal bed gas, the mud volcanic gas and the biological gas. Natural gas can be divided into two kinds of non associated gas and associated gas.

Q: What is the density of natural gas: 4 calorific valueCalorific value refers to the standard 1 cubic meters of a certain amount of gas completely burned out of the heat, belonging to the characteristics of the material, the symbol is Q, the unit is the joule per cubic meter, the symbol is J/m3. Calorific value of high calorific value and low calorific value two.High calorific value refers to a standard cubic meters of gas after the complete combustion of the flue gas is cooled to the original temperature, and the water vapor in the condensed water discharged from the state of heat.Low calorific value refers to a standard cubic meters of gas after the complete combustion of the flue gas is cooled to the original temperature, but the water vapor in the flue gas is still the state of the heat released. The high calorific value of gas is larger than its low calorific value, and the difference is the latent heat of vaporization. Because natural gas is a mixture of gases, different components and different proportions of the components will have different calorific value,

Q: Natural gas is not gas: Gas containing combustible components prepared from coal as raw material. According to the nature and use of gas processing methods, divided into: coal gasification is the water gas and semi water gas, air and gas (or gas), the gas heating value is lower, so it is also called low calorific value gas; gas coking coal carbonization method called coke oven gas, blast furnace gas. The utility model relates to a medium calorific value gas, which can be used as a fuel for the city. Carbon monoxide and hydrogen gas are important chemical raw materials

Q: Which side of the gas cylinder is screwed over there?: Gas cylinder clockwise, counterclockwise open. There will be an arrow on the switch handle.Turn the direction of the more tight, the more open the direction of the more loose.

Q: Is gas natural gas?: No, gas is the gas that occurs when the coal is not completely burned, the main component is carbon monoxide, colorless, odorless, toxic, and was absorbed by the human and animals in the blood after the combination of hemoglobin can cause poisoning. Also called coal poisoning. Natural gas is a multicomponent gas mixture, in which methane is the main component of alkanes, the majority, and a small amount of ethane, propane and butane, in addition also contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, and the amount of inert gas, such as helium and argon. Under standard conditions, methane to butane exists in a gaseous state and pentane is a liquid.
