cryogenic thermo-insulation material

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:What is the composition of natural gas ah? How to do it?
Natural gas refers to natural gas all exist in nature, including all kinds of natural gas of atmosphere, hydrosphere, lithosphere and formation (including oil gas, gas, mud volcano gas and coalbed gas and bio gas generation etc.). The definition of "natural gas", which has been used for a long time, is a narrow definition from the point of view of energy. In petroleum geology, commonly referred to as oil and gas fields. It is composed mainly of hydrocarbons and contains non hydrocarbon gases.
Q:The development trend of 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:Which side of the gas cylinder is screwed over there?
Gas cylinder clockwise, counterclockwise open. There will be an arrow on the switch handle.Turn the direction of the more tight, the more open the direction of the more loose.
Q:Is piped gas natural gas
Do not say, are possible.Pipeline is just a means of transport, the true meaning of the gas is carbon monoxide and hydrogen,
Q:Gas pipe can be buried in the wall
First of all, the gas pipe should be a metal pipe to prevent static electricity, and then not concealed. Together with the sewer pipe should be checked regularly check.
Q:Civil gas tank fire, the best way to fight fire?
The gas tank on fire is not to shut the valve! Can be used when dots. Put out to shut the valve. Otherwise easily lead to explosion!!! On the application of water cooling, the fire quickly extinguished, and then close the valve. This is my safety class to fire the instructor said, have seen the pipeline leakage fire rescue, really, was very puzzled, why not put the valve off first, after that you pay attention to ah!!!
Q:Why is there a component in the gas?In order to prevent
A common cause of gas poisoning(1) using a coal stove in a closed room for heating and cooking, due to poor ventilation, inadequate oxygen supply, can produce a large number of carbon monoxide in the roomThe doors and windows closed, and no ventilation, is not installed or not a correct installation.Negligence, thought paralysis, resulting in a large number of gas overflowThe installation of the chimney is unreasonable, the cylinder mouth is facing the air outlet, so that the gas is turned backWeather conditions are not good, such as wind, snow, cloudy, low pressure, gas flow is difficult to discharge
Q:How much is a cubic gas? Thanks for
At 0 C and 101 325kPa (1 ATM) gas under the condition of the density of 0.7174Kg/m3, is a 0.717kg cubic meters of natural gas, and liquefied natural gas density increased by about 600 times, 0.7174*600=430.44, which is a cubic meters of liquefied natural gas 430kg
Q:How do you see the gas stove with gas or gas?
Look at the label, the cooker model format is usually:JZ * XXXXWhere JZ is a unified home appliance crown, when the back of the R is said to be artificial gas stoves, when Y is said to be liquefied petroleum gas stove, said T when the gas stove. XXXX behind the bar is the manufacturer's model, can not be ignored in the resolution of the gas source.
Q:Natural gas is not gas
Not a thing.The gas is refined by the day after tomorrow.
