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:Natural gas and air density which is higher than that that is when the gas leak upward or floating
The average relative molecular mass of air is 29. At the same temperature and pressure, the density of natural gas is less than that of air
Q:Do you have anything to do with gas?
At present, we use the gas, in fact, basically liquefied petroleum gas.While the liquefied petroleum gas is alkane gas produced in the oil refining process, its complex composition, in addition, in order to let the gas combustion is good, burning fully, as well as the waste water after use remaining in the tank as little as possible
Q:What are the symptoms of inhaling gas
(1) light: poisoning time is short, carbon and oxygen hemoglobin in blood is from 10% to 20%. As the early symptoms of poisoning, dizziness, headache, palpitation, nausea, vomiting, weakness, and even a brief swoon, the general was still awake, inhaling the fresh air from the toxic environment after the symptoms disappear quickly, generally no sequelae.
Q:What is the net content of a can of gas?
According to the relevant provisions of the state,The standard bottle weight is 16.5 kg / A, the weight of the gas is 14.5 kg / bottle (up and down allowed error of 0.5 kg), coupled with the weight of the gas gun, a bottle of gas should be greater than the weight of 32 kg.
Q:Natural gas stove is the first off the valve or off the stove button
Turn off the valve, then close the stove. If you get the order, 1 stove valve is likely to withstand the pressure, the gas between the stove and the valve between the 2 stove was suppressed! Stove valve is easy to leak, although the amount is small, but also pay attention to

Q:Which is more important, natural gas and air?
Natural gas companies are in accordance with the provisions of the government to add odor agent (four thiophene), in order to sniff the user identification.The average molecular weight is 29 and the density is 1.29kg/m3
Q:Why is the gas smelly?
The town gas shall have a detectable odor, and the minimum amount of the odorant in the gas shall comply with the following requirements:(1) non toxic gas leakage into the air to reach the lower limit of the explosion should be aware of 20%;
Q:How to adjust the gas stoveMy home is a liquefied gas stove fire is yellow no sound
If there is no air, the flame is yellow, it is not strong, and there is no pressure in the wood. If the air is too much, the flame is blue and blue, the sound is loud, and it is easy to kill
