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:Do you have natural gas
When used for the sake of safety in the family, in the natural gas added a smell agent, so that when the gas leak will smell the smell, be aware of.If the home is not sensitive to the smell of the elderly or children, it is recommended to install a household gas alarm, as far as possible to choose a qualification, a certificate, a professional insurance gas alarm.
Q:Is steel filled with gas or natural gas?
Liquefied petroleum gasLiquefied petroleum gas (LPG) is a kind of important domestic fuel, which is a by-product of oil refinery catalytic cracking and thermal cracking. Compared with the city gas, liquefied petroleum gas high calorific value, the same volume of liquefied petroleum gas and gas combustion, liquefied petroleum gas calorific value is 20 times the gas.
Q:Gas stove has been broken fire is how
2, check the fire is OK, with the hand will rotate in the burner fire cover on the base to see, some fire a small lump on the cover, the bumps on the base hole alignment press, determine the installation in place,
Q:How did the fire of the gas cooker turn yellow? How to adjust?
This is not how to adjust the problem, gas stove flame is yellow in the liquefied gas adulteration.Method for distinguishing liquefied gas from adulteration"One of the most intuitive way: watch the flame color. In the normal combustion process, the normal liquefied petroleum gas flame was bright blue, combustion is very strong, and after the addition of two methyl ether, due to insufficient combustion, the flame was yellow, blue, very little.
Q:What are the natural gas charges paid by the unit,
If it is the office of enterprises included in the "management fees - Office fees" subjects, canteens included in the "management fees - benefits" subjects, the production workshop is included in the "manufacturing costs", etc.
Q:Will gas be poisoned like gas?
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 6The main components of pyrolysis gas are as follows (%): 12, 5 ~ 7 hydrogen methane and ethane 5 ~ 7, 16 ~ 18, 0.5 ethylene propylene, propane, butane, 7 ~ 8, 4 ~ 0.2 - 5, with 5 or more carbon atoms from 2 to 3 of these hydrocarbons are easily liquefied hydrocarbons, will 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 light light blue flame, combustion process produces a large amount of heat (calorific value is about 92100 kJ/ m3 ~ 121400 kJ/m3)).The calorific value of the three gases: liquefied natural gas is the highest, followed by natural gas, city gas is low. The use of these three gases, such as the stove is not the same, can not be used directly
Q:How to safely use the gas tank, should pay attention to what matters
3, the use of liquefied petroleum gas cylinders must be far away from the heat source, placed in easy to move, not flammable around, more ventilated place, stove, bottle distance of 80 cm or more, shall not be in any form of heating cylinders.4, the use of liquefied gas can not be away from the people, especially the boiling water and do not Rice porridge unattended, so rice soup or water overflow to extinguish the flame, and liquefied petroleum gas appliances continue to emerge, resulting in waste, smoked or fire.
Q:Why should the city's natural gas?
Natural gas has the characteristics of colorless, tasteless and inflammable and explosive
Q:Car burning natural gas has no effect on the car,,
OneOne of the main problems in the use of natural gas vehicles is that the power of the engine is significantly lower than that of gasoline. According to reports, the car in the use of natural gas as fuel, power generally declinedThe main reason for the decline of the power of natural gas vehicles is the characteristics of the fuel and the structure of the engine.
Q:This morning, the new gas tank, after the change will not catch fire
You do not want to open the valve, the gas out too much, the air can not enter, press down gently to the left to turn a little on the line
