Product Description:


cryogenic thermo-insulation material
1.light weight
2.good uniformity
3.low thermal conductivity

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:How natural gas is formed
Compared with the generation of oil, whether it is raw material or production environment, natural gas in Chengdu is more widespread, more quickly and more easily, various types of organic matter can form natural gas -- sapropel type organic matter both source and angry, rot Zhixing organic matter mainly produce gaseous hydrocarbon
Q:About forgetting to turn off the gas
Carelessness is not desirable, a slight negligence of danger! Go out to close the water electricity, the daily use of careful points! Window ventilation is the most important, the valve should be closed quickly. Habits form law, peace and happiness around!
Q:Do you have anything to do with gas?
Liquefied petroleum gas production enterprises, the general will add some chemical additives during filling. In addition, more importantly, originally the liquefied petroleum gas is colorless and odorless gas, but in order to allow people to timely find whether the improper use of liquefied petroleum gas in the liquefied gas leak, the oil inside added toxic gases a rotten egg smell of hydrogen sulfide.
Q:Liquefied petroleum gas and natural gas stove
Different places:1, nozzle: liquefied petroleum gas to burn natural gas, just increase the nozzle diameter can be a little.2, fire cover: liquefied petroleum gas to burn natural gas, the fire cover does not need to be replaced; if it is to burn artificial gas, the fire cover to be replaced by a fire hole or a small fire trough. Can achieve the ideal combustion effect.
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
Q:The calorific value of one cubic meter of natural gas is equal to how much the calorific value of kwh electricity is generated?
The calorific value of gas per cubic meter is 8000 kcal to 8500 kcal, 1 thousand kcal /1 kcal /1000 (kcal) =4.1868 kJ (kJ)
Q:What are the by-products of natural gas
Oil and gas, petroleum gas, petroleum gas. Oil and gas only called natural gas; oil and oil gas, the petroleum gas called oil gas or petroleum gas
Q:Why don't you turn on the lights and call the gas leak
In addition in the gas leak. Firefighters rescue, even the doors are not kick, can not use metal utensils or knock hit, to prevent sparks or detonate gas. So, is not to say that as long as the lights or call in gas leakage room will explode, but cannot do this purpose is just in case.
Q:What is the density of natural gas
1 density and relative densityUnder normal temperature and atmospheric pressure, the density of methane is 0.7174kg/m3, the relative density is 0.5548.The density of natural gas is generally 0.75 kg/m3 ~ 0.8kg/m3, the relative density is generally from 0.58 to 0.62.2 ignition temperatureThe ignition temperature of methane is 540.3 combustion temperatureThe theoretical combustion temperature of methane is 1970.The theoretical combustion temperature of natural gas can reach 2030.
Q:Which is more important, natural gas and air?
On the ceiling.Because the main component of natural gas is methane, the molecular weight is 16, and oxygen is mainly nitrogen and oxygen, molecular weight is about 29.Therefore, the density of natural gas is smaller than air,So natural gas is heavier than air!
