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: What is the proportion of natural gas?: Cubic meters of natural gas combustion heat value of 8000 kcal to 8500 kcal. The calorific value per kilogram of liquefied petroleum gas is 11000 kcal. The specific gravity of liquefied petroleum gas is 0.55. Combustion heat value per cubic meter is 25200 kcal. Each bottle of liquefied petroleum gas weighs 14.5 kg, a total combustion calorific value of 159500 kcal, equivalent to the combustion heat value of 20 cubic meters of natural gas.

Q: Does the electronic ignition gas stove need the battery?If the battery needs to be replaced?If you do not need a battery, that is what the principle of ignition, has been able to use it?: Electronic ignition cooker for desktop, it is through the electronic ignition block ignition assembly embedded, ignition times can use tens of thousands of times, generally ten years no problem, said a lighter ignition principle is simple in principle as usually used.

Q: Natural gas, liquefied petroleum gas, gas, propane, what is the difference?: Coal gas: a combustible gas that is produced from coal as raw material. According to the nature and use of gas processing methods, divided into: coal gasification is the water gas and semi water gas, air and gas (or gas), the gas heating value is lower, so it is also called low calorific value gas; gas coking coal carbonization method called coke oven gas, blast furnace gas. The utility model relates to a medium calorific value gas, which can be used as a fuel for the city. Carbon monoxide and hydrogen gas are important chemical raw materials.

Q: How many cubes can a jar of gas cylinders: General household is 15kg, the standard condition of about 6 cubic meters less than (total residual liquid)The largest 50kg cylinder (for general industrial use) is less than 20 cubic meters

Q: Sunday and her husband with a big clean-upThere is a lot of oil pollution in the gas stove, so scrub it with waterThe results can not be washed after the fireThe gas is out of breathHow to solve? Please advice!: 3, to see whether it is the thermal needle, if there is alcohol home, can also use chopsticks dipped a little alcohol first, and then hit the gas stove, the flames into the small mouth very fire, if the fire stove, first off valve burning after a while, repeated several times just fine.

Q: How many cubic meters of natural gas is equivalent to a tank of liquefied petroleum gas?: I know what you want to know, and I'll introduce you to the value of the heat. In theory, the calorific value of liquefied petroleum gas is 104.6540MJ/m3, the calorific value of natural gas is 40 MJ/m3, but because of different origin, the process is different, so in fact they are different in the market value of the heat. A reporter has done an investigation on this issue, and now I introduce it to you, I hope to help you understand the situation in this regard.

Q: Is piped gas natural gas: But people used to call all the domestic gas gas, including natural gas and liquefied petroleum gas.

Q: What are the similarities and differences between liquefied petroleum gas stove and gas stove?: Because the gas source is different, the calorific value of the gas, the gas pressure is also different. There are marked on the normal stove for natural gas or liquefied petroleum gas, two kinds of stoves can not be mixed, there will be dangerousDifference: nozzle a larger outlet, a small outlet

Q: Gas tank valve must not be closed every timeGas stove after each run out, is only the stove switch off, gas tank valve is not closed: Because the stove and the gas tank is connected with a hose, far away, the interface is more flexible hose is also relatively easy to issue

Q: Natural gas is how to find?: Huojing deep springs high fluorescent to sink, smoke fly in the day hanging fan." This is the people of Sichuan Huojing poetic description, much earlier than this, Yang Xiong in the Western Han Dynasty in "Shu Fu", has been listed as one of the important sites in Sichuan well, visible Huojing long-standing. As for cooking salt using natural gas, people in practice, to realize the natural gas to spontaneous combustion and combustion performance of the Han Dynasty, has overcome the difficulties of Huojing explosion and dress with bamboo, natural gas, similar to today's natural gas storage tank, the creation method of natural gas utilization, on the use of Huojing boiled salt from more detailed, is found in the "Heavenly Creations", the book also painted Huojing boiled salt figure.
