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: My family is several times a month, ah, I only two people.: Your home is not a general, our four large and small, electricity is 300 yuan for two months or so, the air conditioning is not the peak, if the summer is 600 dollars for two months, two months of 100 water, gas pipeline is also used, cooking and bathing, a month is probably around 80, in addition my home soup is electric home appliances are not many, two Taiwan two, two Taiwan computer, washing machine, refrigerator air conditioning on each one, we opened the room more

Q: Why are you always out of breath? Is there enough air pressure? But I heard a liquid inside?: 2 I said the 25 day in the summer, every day need to use3 if it is spring and autumn days at home with a gas bottle bath, it should be around 20 days

Q: Where is the source of natural gas in China: The remains of the natural gas system, which have been deposited underground for a long time, are converted into gas hydrocarbons by the gradual transformation and pyrolysis.The natural gas reserves in underground porous about 3000 - 4000 meters of rock, mainly methane, the proportion of 0.65, lighter than air, colorless, tasteless, non-toxic and has the characteristics of natural gas companies comply with government regulations add deodorant, for users of olfactometry.

Q: What are the by-products of natural gas: Usually referred to as dry gas containing more than 90% of methane, containing less than 90% of methane is called moisture. The remains of the natural gas system, which have been deposited underground for a long time, are converted into gas hydrocarbons by the gradual transformation and pyrolysis.

Q: What are the advantages of natural gas as a source of energy compared with coal: Natural gas as automotive fuel, has high calorific value, low pollution exhaust and reliable supply, low price advantage, has become the world's car with the development direction of clean fuel, and natural gas vehicles has become the fastest growing, most use of new energy vehicles.However, for the greenhouse effect, natural gas and coal, oil will produce carbon dioxide. Therefore, natural gas can not be used as a new energy. Its advantages are:

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: How to use the gas to burn the pot is very black how to solve it: The reason why the gas stove burns the torch pot is black:1, the stove stove head with carbon steel brush clean, need to find.2, is due to the long time no use, there are holes in the spider web block, you can take the stove under the pin, with small things through the spray hole, take out foreign body. The stove is installed after the name of a screwdriver, tapping the stove, is carbon fly, blue flame can be.

Q: Is gas natural gas?: No, gas is the gas that occurs when the coal is not completely burned, the main component is carbon monoxide, colorless, odorless, toxic, and was absorbed by the human and animals in the blood after the combination of hemoglobin can cause poisoning. Also called coal poisoning. Natural gas is a multicomponent gas mixture, in which methane is the main component of alkanes, the majority, and a small amount of ethane, propane and butane, in addition also contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, and the amount of inert gas, such as helium and argon. Under standard conditions, methane to butane exists in a gaseous state and pentane is a liquid.

Q: Is there a place where there is gas?: The question you ask is not clear. If there's no oil in your house.In general, underground oil and gas reservoirs are oil and gas coexistence, of course, oily gas less known as oil, gas called gas oil associated gas; much less is known as gas field, such as the Longgang gas field, Puguang gas field in Sichuan, where the oil is generally called condensate oil, the quality is generally good; the domestic oil field more than less, the main reason is the exploitation of application in our country and ignore the early emphasis on oil and gas fields, since 2000 began to develop natural gas as a clean energy.

Q: Who knows: oil and gas metal pipeline flange need to do cross connection? Action? According to what: Electrostatic grounding is not to decide the number of the flange bolts, is based on the measured resistance value to decide, so the requirements of electrostatic grounding: TSG D0001-2009 "pressure pipe safety technology supervision regulation for industrial pipeline" eightieth pipe electrostatic grounding requirements, the resistance value should be measured joint resistance and pipeline system. When the resistance value is more than 20801 or GB/T provisions of the design documents at,
