cryogenic thermo-insulation material

Cryogenic insulation paper/radiation shield compositions:

Cryogenic insulation paper(P paper/Z paper)/aluminum foil(or aluminized polyester film) compositions are laminated of Cryogenic insulation paper and aluminum foil(or aluminized polyester film).These products can be wrapped to the cryogenic inner tank directly and no need to composite by user. Therefore ,it can effectively reduce the waste of material and hugely increases efficiency. The width varies from 40mm to 1800mm.

Q: There are two gas cylinders at home, a long time no use, and one of them have been put down for more than a year... The bottom of the gas tank is out of paint.. Very worried! I don't know if it will be a problem I'd like to know a little bit about the knowledge! Thank you！: The gas tank is transportable pressure vessel steel, with explosion danger, it is only about 2.5 mm wall thickness (cylinder wall thickness calibration), very thin, it all the time under pressure from internal media generated during normal use of internal pressure (pressure) from 0.5 to 1 trillion and 200 billion Pascal ($from 5 to 12 kg / cm2), the cross section will be 1000 kilograms of tension.

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: How much is the gas in the gas tank?: Gas tank is a movable steel pressure vessel, with the risk of explosion, its wall thickness of only about 2.5 mm (new cylinder factory calibration wall thickness), very book, it always bear the pressure from the internal medium

Q: When the family's natural gas cooking, do not open the opportunity to produce fumes fumes?: That is because urban residents use piped gas, carbon monoxide concentration in the pipeline of 25% to 30%, if the pipeline leaks

Q: What is the net content of a can of gas?: So you know how heavy the gas tank is and the weight of the gasGas tank is generally 33 pounds plus gas full pipe must be less than a total of less than a total of less than 30 pounds of 63 pounds

Q: Before the fire is blue now the fire is yellow and the bottom of the pot to burn black is the gas is not pure or stove need to adjust?: This is not how to adjust the problem, gas stove flame is yellow in the liquefied gas adulteration.Method for distinguishing liquefied gas from adulteration"One of the most intuitive way: watch the flame color. In the normal combustion process, the normal liquefied petroleum gas flame was bright blue, combustion is very strong, and after the addition of two methyl ether, due to insufficient combustion, the flame was yellow, blue, very little.

Q: Which side of the gas cylinder is screwed over there?: Gas cylinder clockwise, counterclockwise open. There will be an arrow on the switch handle.Turn the direction of the more tight, the more open the direction of the more loose.

Q: What are the classification of natural gas: According to the classification of natural gas can be divided into: free gas, dissolved gas, adsorption gas and solid gas;Classification of natural gas by economic value can be divided into: conventional natural gas and unconventional natural gas

Q: What is the standard unit of natural gas?N cubic meters; S cubic meters; and what is the difference between cubic meters?There is no one answer to the.Nm3, is the standard atmosphere, zero perturbation when the volume of gas, which is the international standard; M3 is the standard of China, sometimes written as [M3 (CHN}=], is the standard atmosphere, the gas volume of 20 perturbation);: 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: I would like to ask the electric water heater is good or good gas: At present, there are two kinds of water heater suitable for household use in the market. The utility model is characterized in that the fuel gas water heater is divided into liquefied petroleum gas, artificial gas and natural gas, and the electric heating type water heater also comprises a water storage type and a hot type type.
