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:How to open the automatic valve of natural gas alarm
Open the valve manually after normal use, please check whether there is a preliminary home gas leak, method of ear whether there is air sound, smell smell, apply soapy water after to see whether there is a bubble, avoid fire leak testing, if found to have leaked into the household immediately closed the valve, the ventilation window, contact the Gas Co to help.
Q:The development trend of natural gas
Natural gas, coal and oil are the three pillars of the world's primary energy. Natural gas reserves and exploitation are large, its basic component is methane. It is not only a cheap chemical raw materials, mainly used as fuel, it is not only as a resident's living fuel, but also be used as vehicles, ships, aircraft and other means of transport fuel.
Q:Natural gas is not new energy? Why?
A long time ago, natural gas, there is no new energy. The new energy should be solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy, etc..
Q:The valve and the stove domestic natural gas tube to connect with what
There are two kinds of hard and soft pipes, the hard tube is used to fix the stove. Multipurpose hose for household stove.
Q:Renovation of the new premises of the gas is not open, can be installed gas stove
Small gas general until most of the tenants after completion of renovation and acceptance of property companies, Gas Co have acceptance gas equipment will be changed. Wait until after the full acceptance of the Gas Co will conduct ignition test.
Q:How to judge the use of gas or gas at home
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.Natural gas (natural gas) also known as oil gas, liquefied petroleum gas, petroleum gas. The main component is methane, but also contains a small amount of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc.. Oil and gas only called natural gas; oil and oil gas, the petroleum gas called oil gas or petroleum gas. The chemical composition of natural gas and its physical and chemical properties vary from place to place, no hydrogen sulfide is colorless, odorless, flammable and explosive gases, density of 0.6 ~ 0.8g/cm3, lighter than air. Usually referred to as dry gas containing more than 90% of methane, containing less than 90% of methane is called moisture.
Q:What is the standard unit of natural gas?
For example, a prized car water volume of 18 cubic meters, the actual gas to 3000-4000 gas. Here the gas is compressed to 18 cubic meters of small, but the pressure to 200 kg, after the release to 3000-4000N cubic meters.
Q:How to do mild coal
Different degrees and symptoms of gas poisoning1, mild poisoning: a large amount of carbon monoxide in environment, dizziness, headache, vertigo, tinnitus, nausea, vomiting, fatigue, palpitation. At this time, if you can be aware of carbon monoxide poisoning should be timely window ventilation, inhalation of fresh air, symptoms quickly reduced, disappeared.
Q:Is there a place where there is gas?
Where there is gas, there may not be oil.Natural gas and geological conditions are not the same, the formation of natural gas environment might not form oil; but where petroleum can form symbiosis of natural gas, so that the natural gas does not have oil, oil and natural gas have a certain place.
Q:Natural gas stove is the first off the valve or off the stove button
Natural gas is very safe, you can rest assured that the use of;3, the combustion value of natural gas is relatively low (small molecular weight, low carbon content), the need to use a dedicated stove to make it fully burning; buy stoves must be specific to the type of gas.4, if the use of liquefied petroleum gas liquefied petroleum gas stove, then the flame red, smoke (combustion is not sufficient) under normal circumstances should be a blue flame.
