Aluminum Foil Composite Cryogenic Adiabatic 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:Is the gas in the house toxic?
Gas poisoning is carbon monoxide poisoning, is due to the high concentration of carbon monoxide gas inhalation of the human body and lead to poisoning, hypoxia caused by severe damage to the nervous system. Carbon monoxide inhalation of gas, combined with hemoglobin in the blood, the formation of carbon monoxide hemoglobin, so that the blood loss of oxygen carrying capacity, and can increase tissue hypoxia.
Q:How does natural gas exist underground?
In the total amount of resources, the Cenozoic accounted for 37.3%, Mesozoic group of the upper Paleozoic, the upper Paleozoic of the world, the lower Paleozoic of the year 25.5%, 26.1%. The genetic type of natural gas resources, high maturity of the pyrolysis gas and coalbed methane dominated respectively of the total amount of resources 28.3% and 20.6%, oil gas in coalbed gas accounted for 18.8%, accounted for 27.6%, accounting for 4.7% of biogenic gas. Chinese natural gas reserves are concentrated in 10 large basins, followed by: Bohai, Sichuan, Junggar, Songliao, Yinggehai and Qiongdongnan, Qaidam Basin, Turpan, Tarim, Bohai, Ordos. The gas fields in China are mainly small and medium, and the geological structures of most gas fields are complex. 1991-1995, China's natural gas production increased from 16 billion 73 million M3 to 17 billion 947 million m3, with an average annual growth rate of 2.33%.
Q:What is the amount of heat contained in a natural gas
That is, the calorific value per cubic meter is equivalent to 9.3 to 9.88 degrees,3.83<1.07*9.3 OR 9.88
Q:Natural gas can not be renewable
2, the development and utilization of renewable energy is an important measure to protect the environment and respond to climate change. At present, the problems of environmental pollution in China is prominent, the fragile ecosystem, a large number of mining and use of fossil energy great impact on the environment, especially the high proportion of coal in China's energy consumption structure, carbon dioxide emissions increased rapidly, has great influence on climate change. Renewable energy clean environmental protection, development and utilization process does not increase greenhouse gas emissions. The development and utilization of renewable energy plays an important role in optimizing the energy structure, protecting the environment, reducing greenhouse gas emissions, and dealing with climate change.
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:What is the difference between a gas producer and a cold gas?
According to the fuel station and the purification method of different gas producer, customarily divided into two types: namely, the hot and cold gas station gas station. While coal and anthracite and bituminous coal (including coke) two categories. So strictly speaking should be divided into four cases:
Q:How to convert natural gas from cubic to tons?
Natural gas per ton:1000/0.7192 = 1390 cubic metersThe above algorithm is more accurate, but too cumbersomeI can introduce a simple estimation method for any gas, but not very accurateIt is known that the molecular weight of water molecules is 18 and the density is about 1 kg / LUsually converted to liquid or solid gas and gas that is at 20 degrees and a standard atmospheric pressure, the volume of about more than 1000 times, and specific to the water is about 1200 times. It is in 20 degrees, a standard pressure water vapor volume of 1.2 cubic meters.This 1.2 cubic meters of water vapor is from a liter of water (a kilogram) to change, so the water vapor density: 0.8333 kg / cubic meterThe density of natural gas:Molecular water vapor density * gas molecular weight, the amount of water=0.8333 * 16 18=0.7407 / kg / m3
Q:This morning, the new gas tank, after the change will not catch fire
Can reduce the pressure relief valve or a bottle of gas to try.
Q:What is the difference between acetylene and gas?
Mainly for industrial use, especially the welding metal. Acetylene is a colorless at room temperature
