Cryogenic Thermal Insulation Paper

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: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.
Q:Explain the cause of the expansion of the volume of natural gas after decompression
There is an interval between molecules. When the pressure increases, the space between the molecules becomes smaller and the volume becomes smaller. When the pressure decreases, the gap between the molecules becomes larger and the volume becomes larger
Q:How much is a gas tank empty?
50 or so to see you do not steal itTheir own can sell 60--70 oh
Q:How does natural gas exist underground?
The sedimentary rocks in China are widely distributed in the continental basins, forming a variety of favorable geological conditions for natural gas storage. According to the forecast of natural gas resources in China in 1993, China's total natural gas resources amount to 38 trillion m3, the onshore natural gas is mainly distributed in the central and western regions, accounting for about 43.2% of the land resources and the total amount of natural gas resources, respectively, and the total amount of natural gas resources in China is 39%. The distribution of the natural gas resources in China is dominated by the Cenozoic third and Paleozoic strata
Q:The gas stove is burning my black bottom to do
But because of the combustion of acetylene acetylene carbon atom itself caused by the excess carbon atoms overflow, more carbon atoms will be attached to the objects gradually formed around carbon black, this is no matter how dark will cause burning pot.
Q:What is the difference between the cooker and the gas cooker
The cooker can be burned on a gas cooker!If the pan is used on the gas stove, it can be used to guide the magnetic field, and the bottom of the pot is larger than 10 cm!Rest assured that the use of bar!
Q:Pipeline natural gas will not cause gas poisoning?
Liquefied petroleum gas (LPG) is a by-product of refinery catalytic cracking and thermal cracking.The main components of the catalytic cracking gas are as follows: (5) hydrogen, methane, ethane, ethylene, ethylene oxide, ethylene oxide, ethylene oxide, ethylene oxide, 10 ~ 6, ethylene, ethane, ethylene, propylene, ethylene glycol, ethylene glycol, ethylene oxide, ethylene oxide, ethylene, gas and water, the main components of the gas are as follows: (42) to hydrogen, methane, ethane, ethylene, ethylene oxide, ethylene oxide, ethylene, ethylene oxide, ethylene and propylene, the methane is from 5 to 5, ethane to ethylene, ethylene, ethylene oxide, ethylene and propylene, which is from 3 to 3, propane to propylene by ~ ~ ~ (s), propylene from 16 to 20, propylene from 6 to 11, butane from ~ (c) to ~ 46, butene from ~ (5) to about 6.The main components of the thermal cracking gas are as follows: (7): hydrogen, methane, 5 ~ ~ (s), ethane ~ ~ ~ ~ 7, ethylene, ethylene glycol, ethylene oxide, propylene glycol, propylene oxide, propylene glycol, propylene glycol, ethylene glycol, 5 to 18, propane, propylene, propylene glycol, propylene glycol, propylene glycol, 7 to 8, butane, butene, 4 to 5, containing more than 5 carbon atoms of hydrocarbons from 2 to ~ 0.2 ~ (3) ~ ~ ~ ~ ~ ~ ~ ~ (12). These hydrocarbons are easily liquefied, they are compressed to only the original volume of 1/250 ~ l/33, stored in the high pressure resistant steel tank, the valve open gas tank when used in flammable hydrocarbons gas goes through a pipe into the burner. After the formation of a light blue flame, combustion process produces a lot of heat (calorific value is about 92100 kJ/m3 ~ 121400 kJ/m3).The calorific value of the three gases: liquefied gas is the highest, followed by natural gas, city gas is lower. The use of these three kinds of gas stove is not the same, can not be directly used interchangeably.
Q:How can I get the gas cooker?
The first to open the gas tank, the right hand is the direction of their own twist, and then turn on the gas stove can be it, very simple
Q:How many cubic gas is a gas tank?
1 cubic meters of liquefied natural gas equivalent to about 2.5 cubic meters of natural gas combustion effect of a tank equal to the equivalent of 5.6 cubic meters of liquefied petroleum gas is equivalent to one cubic meter of natural gas
Q:A lot of stoves and water heaters that use artificial gas can be converted to natural gas
The stove and water heater manufacturers can be door-to-door service, usually for natural gas nozzle. Natural gas company at the beginning of the artificial coal gas into natural gas, but also provide services, Sacon and other brands must by the manufacturer.
