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:Natural gas from the standard into the quality of how to calculate?
One cubic meter of natural gas quality: 0.7192 kgPer ton of natural gas volume: 1390 cubic metersNatural gas transportation or trading is generally calculated in cubic metersConversion methods are as follows:Standard cubic meters of natural gas refers to 1 atmospheric pressure, when the 1 cubic meters of 20 degrees CelsiusUnder this condition, any 22.4 liter of gas contains one mole (6.02 x 10^23) moleculesOne cubic meter is 1000 litres
Q:What is the difference between liquid gas and natural gas
Liquid gas is a kind of combustible gas which is produced by refining oil and liquefied at high pressure and low temperature
Q:Is the gas in the house toxic?
Mild poisoning, headache, dizziness, tinnitus, nausea, vomiting, palpitations, weakness, etc.. Out of the toxic environment, inhalation of fresh air, a few hours after recovery. In addition to the above symptoms of moderate poisoning, and flushing, cherry red lips, rapid pulse, sweating, irritability, lethargy, gait instability and even coma. General treatment 1 ~ 2 days can be restored, no obvious sequelae. Severe poisoning can quickly coma, lasting several hours to several days. Deep poisoning often complicated by pneumonia, pulmonary edema, myocardial damage, toxic neuropsychiatric disorders.
Q:Natural gas is how to find?
In order to develop oil and gas, the working people of China have gradually invented a set of drilling technology. In the Warring States period more than 2200 years ago, the ancestors of the Chinese people have dug deeper wells, since the Han Dynasty, the working people to promote and improve the drilling machine. To the Song Dynasty deep drilling machine has formed a quite complex mechanical combination. Generally, the big hole was cut off, and the well was dug into a well. To the Ming Dynasty, drilling machinery and equipment and technology has been further developed.By contrast, it was not until 1659 that the natural gas was discovered in England, and that it was not widely used. By 1790, gas had become the main fuel for street lighting in europe. In North America, the first commercial application of petroleum products is the application of natural gas in New York in 1821, Floyd, they through a small bore catheter for delivering gas to the user, for lighting and cooking. The development and utilization of natural gas in the world, the United States in 1925 laying the first gas pipeline as a symbol of modern industrial use.
Q:Could you tell me the difference between liquefied petroleum gas and natural gas
Liquefied petroleum gas and natural gas composition is different, the amount of oxygen needed when they burn, under normal circumstances, the combustion of natural gas required for the amount of oxygen required for complete combustion of liquefied petroleum gas is less than the amount of oxygen. So, can not use exactly the same range. The original stove after the burning of natural gas, to reduce or increase the air intake vents. So you only need the air valve nozzle and the original stoves replaced for burning gas can, not too expensive. If you can change it by now spend little money for the stove nozzle and the valve plate you can use natural gas.
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.
Q:8L of natural gas water heater, 10L,
JSQ20-10P3, in fact, these letters and numbers has his specific meaning! JS is the product code (gas water heater), Q is the way (D flue type Q strongplatoon type, G said the mandatory balanced W outdoor)
Q:How can I get the gas cooker?
The first to open the gas tank, the right hand is the direction of their own twist, and then turn on the gas stove can be it, very simple
Q:The gas stove must press on, or it will turn off
See if there is a burning flame thermocouple, if not, indicating that the solenoid valve is not open, the gas source did not flow to the fire hole, so a loose hand solenoid valve is also closed, the flame went out
Q:How to convert natural gas from cubic to tons?
One cubic meter of natural gas quality: 0.7192 kgPer ton of natural gas volume: 1390 cubic metersNatural gas transportation or trading is generally calculated in cubic meters
