aluminosilicate refractory fiber paper for lng cryogenic storage

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: How to judge the use of gas or gas at home: The main content of gas is carbon monoxide, hydrogen, etc.. The main content of natural gas is methane. When the two gases are detected, the parameters are different. Carbon monoxide poisoning. So they are treated as toxicity. Natural gas is flammable and explosive.

Q: For the development trend of natural gas? And cognitive level: why do people have a great deal of knowledge about natural gas?: Natural gas, coal and oil are the three pillars of the world's primary energy. Natural gas reserves and exploitation are large, its basic component is methane. It is not only a cheap chemical raw materials, mainly used as fuel, it is not only as a resident's living fuel, but also be used as vehicles, ships, aircraft and other means of transport fuel.

Q: Is natural gas solid?If so, under what conditions will become solid?: When it comes to energy, people think of coal, oil, or natural gas, and seldom think of the crystal clear ice". However, since 1960s, people have been in the tundra and the depths of the ocean to find a burning ice". This "combustible ice" in geology is called natural gas hydrate (Natural Gas Hydrate Gas, referred to as Hydrate), also known as the "clathrate" (Clathrate), molecular formula: CH4 - nH2O, it has been confirmed that the molecular structure of CH4 - 8H2O.

Q: Is the gas escaping from the pipe floating up or down?: Methane (CH4) molecular weight was 16, and the air is a mixture of methane relative quality was 29, the relative quality of air quality is relatively less than doing so!!!!!!!

Q: Ditto, or the history of the development of China's gas; thank you: June, Qinhuangdao to Beijing oil pipeline was completed in December 27, 1974, Daqing to Qinhuangdao oil pipeline has been completed and began to oil, so far, Daqing oilfield crude oil directly to Beijing. In July, the oil wells of the 4 well in the Gulf of Bohai were ejected from the ancient volcanic rocks in the carbonate rocks. 17 months, Changchun coal gas plant completed and put into production. July 3rd, Hebei, Renqiu hit a high-yield wells, found in Renqiu oilfield.

Q: What are the symptoms of inhaling gas: In case of gas poisoning in the family, the main:(1) open the doors and windows immediately and move the patient in a well ventilated place with fresh air. Find the cause of the gas leakage, eliminate hidden dangers.(2) release button, keeping respiratory tract unobstructed, clear respiratory secretions, such as respiratory arrest, should immediately do mouth to mouth resuscitation, and make cardiac massage in vitro.(3) immediate acupuncture treatment, acupuncture, lack of people, taking less, ten Xuan, Hegu, Zusanli springs, sun, etc.. Light, moderate poisoning, acupuncture can be gradually regained consciousness.

Q: What is the difference between natural gas and coal gas: A: gas and natural gas is a common feature of easy to use, clean and dust-free, and are all through the gas pipeline into the home, therefore, very...

Q: Is it okay to turn off the gas stove after using the gas?: 3, the use of natural gas should first ignition, after the gas. Once not lit, to quickly close the gas stove switch, should not be deflated, after ignition. When using the automatic ignition stove, push the switch knob in the direction of the arrow, ignition and adjust the flame size.4, the use of natural gas stove, please do not stay away and pay attention to observe, in order to prevent the flame was boiling water overflow or blown out by the wind. And pay attention to the kitchen ventilation, keep indoor air fresh.5, use, pay attention to close the gas stove or water heater switch, at the same time the table before the valve is closed, to ensure safety.6, in the course of the use of gas in case of sudden interruption of gas supply, the gas switch should be closed in time to prevent air mixed into the pipeline. In the recovery of gas supply pipe should be used in the air emissions.7, do not install the gas pipeline and gas facilities in the indoor storage of flammable and explosive goods.

Q: Car burning natural gas has no effect on the car,,: When the vehicle is made of natural gas, it is found that the combustion chamber is obviously corroded, and even the crankshaft is corroded. The valve, piston ring and cylinder are seriously wornThis is another problem faced by natural gas vehicles. The reason for the corrosion and early wear of natural gas vehicles is that there are trace sulfur compounds in natural 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.
