insulation paper

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:Liquefied natural gas water heater
Technical principleAs long as the master of the gas composition and principle of gas water heater principle, any gas water heater can be changed to the use of any gas source, gas water heater can be converted into liquefied gas, liquefied gas water heater into natural gas also is feasible, but some special gas transformation technology needs to consider whether the gas water heater is the gas channel required to meet the requirements of gas flow, such as a liquefied gas water heater modification of adult gas, one thing that is particularly difficult and renovation costs are particularly high, because of the low calorific value gas, nozzle aperture, so the traffic is particularly large, can not be achieved using flow the requirements of liquefied gas water heater general transformation, so the transformation of the way in reality is not exist. In reality, the existence of natural gas is the main water heater to liquefied gas (bottled gas) or liquefied petroleum gas to natural gas more, and these two kinds of gas to the heater gas flow requirements are not too high, so after the transformation in use can meet the required performance requirements.
Q:Use of natural gas will cause air pollution?
Natural gas will produce carbon dioxide and water, in this regard, natural gas than coal, such as coal derived from the Carboniferous fuel is much less. So it is not that it will not cause pollution, but relatively few, relatively clean, resulting in a relatively short greenhouse effect.
Q:What is the difference between liquid gas and natural gas
Liquefied natural gas (LNG) is a kind of form of energy utilization after liquefaction of natural gasNatural gas condensate is a kind of light hydrocarbon mixture, which is mainly composed of ethane, propane and butane
Q:What are the symptoms of inhaling gas
(1) light: poisoning time is short, carbon and oxygen hemoglobin in blood is from 10% to 20%. As the early symptoms of poisoning, dizziness, headache, palpitation, nausea, vomiting, weakness, and even a brief swoon, the general was still awake, inhaling the fresh air from the toxic environment after the symptoms disappear quickly, generally no sequelae.
Q:What is the amount of heat contained in a natural gas
So the calorific value per cubic meter is 33494.4 - 35587.8KJ.And 1 degrees =1kW*h=3.6*10^6J=3.6*10^3KJ.
Q:Natural gas stove is the first off the valve or off the stove button
1, tempering in the outside pressure is greater than the pressure of natural gas pipeline, the outside world gas into the gas pipeline and be lit will backfire. The harm of tempering is the explosion of natural gas pipeline (especially the explosion of indoor non metallic hose, whose strength is lower than that of steel pipe) and the possibility of fire. However, this problem will not occur in natural gas, so the user does not require the installation of tempering stopper.
Q:What is the stripping gas in natural gas desulfurization process?
The content of carbon dioxide is too high, which puts forward higher requirements for the desulfurization process, desulfurization agent and desulfurization equipment. The desulfurization Changchun Dongshi Science & Trade Industrial Co. Ltd. east lion desulfurization technology collaboration network technology as a platform for domestic wet oxidation desulfurization in recent years focused on biogas industry, from desulfurization to professional desulfurization desulfurization equipment research and improvement has done a lot of work.
Q:The nature of blast furnace gas
3, blast furnace gas is a highly toxic gas, the human body in a short period of time to contact a large number of gas, CO and hemoglobin in the blood with the formation of carboxyhemoglobin, causing tissue hypoxia, causes acute poisoning. So long time working in the area of gas, carbon monoxide concentration not more than 30mg/m3 (24ppm).
Q:Why don't you turn on the lights and call the gas leak
But these spark temperature is not low, once ignited in air gas, is caused by the explosion (do you have a light bulb will burst through, then not only spark may even produce arc, if such a thing happened, in a room filled with gas consequences as can be imagined)
Q:Found in the indoor gas leak should be how to do?
1) cut off the gas source. (2) put an end to the fire. It is strictly prohibited to open all kinds of electrical equipment in the room, such as turning on the lights, making phone calls, etc.. (3) ventilation. Should open the doors and windows in time, should not open the exhaust fan, so as not to ignite indoor mixed gas, causing explosion. (4) can not quickly remove the chemical fiber clothing, so as not to cause the explosion caused by static electricity sparks. (5) if the neighbor has a gas leak, not allowed to ring the doorbell, should inform the door. (6) to the outside call the local gas repair alarm call or 119.
