flame-retardant cryogenic insulation paper

Flame-retardant cryogenic insulation paper(compatibility with oxygen) :

The flame-retardant cryogenic insulation paper is made of super-thin glass wool, which is produced in all -electrical kiln with blaze technology, by a peculiar manufactory process. The insulation paper is often composited with aluminum foil as a thermal insulation material for using in the vacuum jackets of storage and transportation vessels for cryogenic liquids(Liquid Hydrogen liquid oxygen, LNG, liquid Helium, liquid Nitrogen and liquid Argon).Its advantage are flame-retardant at open fire and with the best thermal insulation characteristic(lower thermal conductivity, higher contact thermal resistance),low outgassing rate, light weight, high uniformity and wide range of the application temperature:-269°C-800°C

Q:What are the symptoms of inhaling gas: The family of gas poisoning mainly refers to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas, natural gas poisoning, the former is more common in winter heating coal stove, doors and windows closed, smoke is poor, which is common to liquefied gas pipeline leak leak or stove. Gas poisoning patients initially feel headache, dizziness, nausea, vomiting, weak and feeble, when he realized the poisoning, often struggle out of bed to open the door, open the window, but only a few people can open the door, most of the patients rapidly pumping spasm, coma, cheeks, chest skin and lips of cherry red colour, if the treatment is not timely. But soon died of respiratory depression. According to the concentration of carbon monoxide in the air and the time of poisoning, gas poisoning is usually divided into three types:

Q:Car burning natural gas has no effect on the car,,: In terms of fuel properties, gasoline is a liquid fuel, while natural gas is a gas fuel. The use of gasoline, and the volume of the air intake volume of liquid gasoline compared to almost negligible, but the use of natural gas as fuel, fuel volume occupies a large proportion in the whole intake, resulting in the amount of air entering the cylinder is reduced, air coefficient decreased, resulting in reduction of engine power.In the engine structure, the main factor to determine engine power is the compression ratio of the engine, the greater the compression ratio, the higher the thermal efficiency, the greater the effective power. At the same time, the greater the compression ratio, the greater the tendency of engine detonation. Therefore, the engine compression ratio must also be consistent with the fuel antiknock. Gasoline antiknock determines the compression ratio of gasoline engine can not be too large, but the natural gas antiknock good, can be used to compress the larger engine, thereby enhancing its power. The application of natural gas vehicles is still in its infancy, the supply of natural gas is not as popular as gasoline, in this case, it is difficult to promote the design of natural gas engine cars. At present, most of the natural gas vehicles put into operation are dual purpose fuel vehicles. In order to take into account the use of gasoline, the dual fuel vehicle has a smaller or no increase in compression ratio. As a result, the characteristics of high anti explosion of natural gas have not been fully utilized, which results in the decrease of engine power.

Q:Could you tell me the difference between liquefied petroleum gas and natural gas: Are oil and "similar"; the main difference is: 1, the proportion of different liquefied petroleum gas is heavier than air, natural gas is lighter than air; 2, mixing it with air to gas deflagration of the mixing ratio is different; 3, the calorific value of produced when they are burned with different calorific value of liquefied gas quality the calorific value of natural gas is 22000 kcal, 8500 kcal is. 4, their composition is different, liquefied petroleum gas is mainly composed of propane or butane, natural gas is methane. It is possible to use the same stove.

Q:Why does the gas smell?: Not carbon monoxide taste. Some sulfur coal has more sulfur dioxide emissions produced by burning. Smell the nose is it there. Therefore, there is no carbon monoxide by smell Weilai judgment is not scientific. To prevent gas poisoning, must be installed to the stove chimney, the gas chimney is communicated to the outside through the best. A scoop in the window above, maintain indoor air circulation.

Q:Where does natural gas come from?: Although the organic theory is an absolute advantage, but in the organic layer of oil under the premise of the existence of marine organisms to produce oil, or land rivers, lakes in the bio oil debate. In reality, in the Middle East, Saudi Arabia, Kuwait and other countries of the large oil fields are marine formation oil, and most of the country's oil field is the formation of terrestrial oil.

Q:How to buy range hood and gas stove: The hood with its beautiful appearance, good smoke exhaust effect, can be matched with different styles of kitchen furniture decoration, moderate price and other characteristics, as the family will share the kitchen appliances. However, consumers buy hood, if you do not grasp the more basic methods, to point, it is easy Cairu optional errors here, on the five aspects of the analysis, I hope to help you get the heart, the right products to a certain extent

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:How natural gas is formed: Therefore, the genesis of natural gas is various. It is concluded that the origin of natural gas can be divided into biogenic gas, oil type gas and coal type gas. In recent years, inorganic gas especially non hydrocarbon is highly valued, here be briefly introduced, finally understand the various causes of discrimination method of gas

Q:For the development trend of natural gas? And cognitive level: why do people have a great deal of knowledge about natural gas?: And the domestic gas pipeline laying slow and limited, so far, there are three ways to use: pipeline gas, liquefied natural gas, compressed natural gas. So there is a great deal of difference between people and natural gas.

Q:Compare the advantages and disadvantages of the two kinds of fuel, honeycomb briquette and coal gas according to the experience of life, and give out the advantages of using the three kinds of gas: (2) to reduce pollution, protect the environment, reduce labor intensity, reduce housework; (3) economic benefits; (4) is conducive to the development of diversified products. Lighter gas. Compared with the air, coke oven gas is lighter, if there is a leak of gas in the room, the upper part of the gas content of space than the lower part of the content is high, therefore, once the gas leak, should immediately open the doors and windows of the wind blowing.
