foil back insulation 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 much is a liquefied natural gas?
The volume expansion ratio of liquefied petroleum gas is about 260 times. 260*30=7800L. Liquefied petroleum gas calorific value of about 25000 kcal per cubic meter, the calorific value of natural gas is about 8500 kcal per cubic meter. 7800* (25000/8500) =22941L. It's probably not the use of heat.
Q:Which is more important, natural gas and air?
Natural gas is stored in underground porous rock, the main component of methane, the proportion of 0.65, lighter than air, with colorless, tasteless, non-toxic characteristics
Q:As soon as the gas ran out, the gas tank was turned upside down
Do not need, as long as the above method can be
Q:Liquefied gas and coal gas _?

Gas Co in the filling, impurity bottle and bottle wall and with the oxide is cleared up, and the weight of material is relatively heavy, but no weight, from a certain extent against you as a consumer of power.
Q:Why does the gas smell?
The ability of carbon monoxide and hemoglobin binding two hundred or three hundred times stronger than oxygen, it caught will cling on hemoglobin, hemoglobin and lose the ability to bind oxygen. People cut off the supply of oxygen, will remain unconscious, dizziness, palpitation, and even death. The content of carbon monoxide in the air to reach the very few of the time, people will poisoning. However, people often have a misconception that the gas is acrid odor, no smell smell no gas.

Should be the reason for the larger range, clear focus is on the stove, adjustable air inlet valve. The gas is mixed with combustion air intake. After the inappropriate will cause a fire red smoke, a good tune is blue. The more complete combustion temperature will become more high.
Q:How to use the gas to burn the pot is very black how to solve it
The reason why the gas stove burns the torch pot is black:1, the stove stove head with carbon steel brush clean, need to find.2, is due to the long time no use, there are holes in the spider web block, you can take the stove under the pin, with small things through the spray hole, take out foreign body. The stove is installed after the name of a screwdriver, tapping the stove, is carbon fly, blue flame can be.
Q:Why is the gas smelly?
In order to be able to detect the gas leak, people in the colorless and tasteless gas to add a small amount of sulfur ether, odd smell incomparable
Q:The gas stove bottom outside going black bag
The bottom of the burning black gas stove, gas stove is not used when the flame is yellow instead of light blue translucent state, if it is, it is the small amount of air mixed gas gas stove burning caused by incomplete combustion of smoke from the bottom of the pot blackened.
