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:Is steel filled with gas or natural gas?
The gas from different sources, different names: the dry distillation of coal and gas called coke oven gas; coal (or coke) in the case of incomplete combustion can be gas; if the carbon and water vapor in high temperature, can get water gas; gas discharged from blast furnace is also quite combustible components the name of blast furnace gas.
Q:Why does the gas smell
It is usually said that the main component of gas is carbon monoxide. Burning coal stove in the winter, because the doors and windows are closed, the room is not ventilated, carbon monoxide can not be generated to spread to the outside, people will be poisoned more. Carbon monoxide has no color, no smell, and is inhaled into the bloodstream through the alveoli, leading to the combination of the oxygen that transports oxygen. The combination of carbon monoxide and hemoglobin is two hundred or three hundred times more powerful than oxygen. It holds the hemoglobin tightly, so that it loses the ability to bind oxygen. People will cut off the supply of oxygen, dizziness, palpitation, remain unconscious, and even death. The amount of carbon monoxide in the air reaches tens of thousands of times, people will be poisoned. However, people tend to have an illusion that the gas has a choking nose smell, no smell no smell of gas.
Q:Gas stove is the cause of ventilation?
The other is the electromagnetic valve is broken, because Vatti uses a single solenoid valve, so after the failure of the solenoid valve on both sides of the electric power can not be normal ignition, looking for aftermarket replacement solenoid valve can be
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:How many cubic meters of gas does a ton of steam boiler produce a ton of steam
First of all we need to know about 1 tons of water into steam to absorb heat, and the heat value of natural gas combustion to release heat, the boiler equipment, passed to the changes of water absorption of heat medium water, physical properties, low temperature and high temperature water into water into steam gasification, it completes the process need to absorb the heat of about 600 thousand kcal natural gas quality.
Q:The working principle of the gas refrigerator?
The working principle of the gas refrigerator is to use the gas to heat the concentrated ammonia water to boil, and the ammonia vapor evaporatedThe water vapor is condensed and liquefied, and ammonia is condensed into liquid ammoniaBecause of the different pressure of the ammonia, the ammonia is diffused into the hydrogen from the ammonia liquid, and the evaporator temperature is reducedFunction.
Q:Role of gas tank pressure relief valve
Because the carbon component of four combustion than carbon three components of combustion need more air, so this may appear yellow flame, the air regulating plate adjustment, so that more air into the combustion gas and help; there will be a small amount of molecular thermal decomposition of carbon particles and carbon particles in the high temperature combustion emission the fire was yellow, at this time up into the air, sometimes the flame is still yellow.As for the selection of Ze valve, of course, to choose a quality assurance.
Q:How many kinds of natural gasWhat are their uses
See you from which angleAccording to the state can be divided into NG (general gaseous natural gas), LNG (liquefied natural gas), CNG (compressed natural gas). NG is generally used to burn, or some enterprises are also used as raw materials for processing, LNG is compressed to liquefied natural gas, mainly used for non pipeline transportation, CNG most of the cases are used for natural gas vehiclesAccording to sulfur content can be divided into high sulfur, low sulfurWater can be divided into dry gas and moisture
Q:The fire of the gas cooker turns red, the smoke is very big, and the bottom of the cooker is black
The gas is impurePure fire is a blue flameMay be mixed with water
Q:How to open the automatic valve of natural gas alarm
Twist it in parallel to the pipe. The valve is normally closed off. If the alarm is not automatically cut off the gas after the alarm, but also to continue to use, please call the gas company to replace the alarm components, if the alarm valve automatically shut down after the alarm,
