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: I bought two new batteries. And bought a new low pressure valve. After a few minutes on the beat. And then you can't beat it. Where is the problem? Open the relief valve and press the ignition switch. The ignition point pops rang. Also hear the sound of gas, why not?: The air duct, the pipe connected to the hot water gas end pull open, and then unscrew the gas tank valve 5 seconds or so, then the pipe back, which under the 0K

Q: Natural gas stove is the first off the valve or off the stove button: Turn off the valve, then close the stove. If you get the order, 1 stove valve is likely to withstand the pressure, the gas between the stove and the valve between the 2 stove was suppressed! Stove valve is easy to leak, although the amount is small, but also pay attention to

Q: Is there a pressure relief valve can not switch off the gas pipeline: Gas tank pressure relief valve is generally not adjusted.Gas tank pressure reducing valve is the role of liquefied gases in the tank to reduce pressure into gas, through the pipeline, leading to gas stoves burning.

Q: How to do mild coal: 2, moderate poisoning: in addition to the above symptoms can appear, sweating, irritability, ataxia, pale skin, blurred consciousness, always feel sleepy, sleepy fatigue. If can be identified in time to take effective measures, the basic can be cured, rarely leave sequelae.3, severe poisoning: an unexpected situation, especially the poisoning caused by sleep at night, was found at the The sun is three poles high., has been unconscious, trismus, body spasm, incontinence, face, lips was cherry red, breathing fast pulse, body temperature may rise. Critically ill person. Persistent coma, weak pulse, irregular breathing, blood pressure drops, also can appear in a temperature of 40 DEG C. At this time have the honor not to die, will also leave serious sequelae, such as dementia, paralysis, loss of work, living ability.

Q: Liquefied petroleum gas cylinder in the home after the valve has been a big fire, gas stove by adjusting the basic do not work, so I want to adjust the pressure relief valve, but I have a half twist counterclockwise, little effect. Do not dare to twist, special to help the general number of twists and turns to see how the effect?: Liquefied gas cylinder pressure in general in the 3-5 kg / cm2, decompression need to burn in the stove, the role of the regulator is to play the role of decompression, the liquefied gas pressure is reduced to about 0.035 kg / cm2. Ordinary civil voltage regulator is not adjustable.

Q: In addition to the wind, but also what conditions?When you wake up, inhaling gas will be uncomfortable?: The composition of the gas in the air and the influence of the human bodyAnd it will happen if it is not ventilated5~10 minute coma10~15 minute shock15~30 minutes of heart failure, brain death

Q: The calorific value of one cubic meter of natural gas is equal to how much the calorific value of kwh electricity is generated?: The calorific value of gas per cubic meter is 8000 kcal to 8500 kcal, 1 thousand kcal /1 kcal /1000 (kcal) =4.1868 kJ (kJ)

Q: Is gas natural gas?: Artificial gas is the main component of carbon monoxide.The main components of the gas are CO, hydrogen and alkanes, olefins, aromatics, etc.. The gas is toxic because of the CO, and the body of the aromatics to hemoglobin, causing hypoxia, make people remain unconscious or even death, can also make people dizzy, nausea and collapse at low concentrations.

Q: Just for the gas, would like to ask you, how to distinguish between gas cooker and gas stove? There is a connection with the burner tube is what material the safety?: Look at the label and the nameplate, there are available gas typesPipe with plastic material on the gas pipe on the line

Q: What are the components of household gas and gas tanks now?: The gas tank is the main component of liquefied petroleum gas, propane, propylene, butane, as butene, anesthetic effect all have strong hydrocarbon composition of liquefied petroleum gas. But due to their solubility in the blood is very small, under the atmospheric conditions, without affecting the physiological functions of the body, if the liquefied petroleum gas concentration in the air is very high, so that the oxygen content in the air is reduced
