The superfine glass fiber Cryogenic & Insulation paper is made of alkali-free glass fiber (diameter between 0.1-0.6μm) and fiber glass filament (diameter between 3-5 μm). According to a certain proportion, the paper is produced under the wet & vacuum forming process to make the paper have the space lattice structure.
All the glass fiber is inorganic material, so it has outstanding flame retardant properties.
Due to the space lattice structure of this paper, it makes both the thermal conductivity coefficient and specific heat flux of interlayer are extremely low when the paper is in a cryogenic environment.
The material properties determine the fiber surface is not easy to be adsorbed gas molecules, so the vacuum speed is fast in a rather short time, and it is good to maintain the required vacuum degree.
Specifically engineered for use at big temperature range (approaching -273℃—500℃) and also the paper is really stable in the low temperature condition.
So the super thermal insulation glass fiber paper is the best solution for the storage tank and transportation of LNG, liquid oxygen, liquid hydrogen and liquid nitrogen.

- Q: How to prevent gas explosion
- Cause of gas explosion:1, gas interruption, reduce pressure in the pipeline, resulting in air intake, so that the air and gas mixture to reach the range of explosion, fire explosion.2, gas equipment overhaul, the gas did not blow clean. And do not rush to fire caused by explosion tests.
- Q: How to distinguish the use of natural gas and gas
- It seems to be natural gas. Instead of gas
- Q: 1 inch water gas pipe diameter
- Water gas pipe? Galvanized pipe or pipe. 1 inches is the British law, such as the outer diameter of a variety of 4. The British 1 inch is divided into 8 points, so the is 1/2 inches, 6 minutes is 3/4 inches, the 8 point is the size of 1 inches4 in charge of 12 - diameter 12.5mm often say DN156 in charge of 34 --- --- diameter 19mm DN201 inch tube 1 "--- diameter 25.4mm DN25
- Q: Renovation of the new premises of the gas is not open, can be installed gas stove
- Small gas general until most of the tenants after completion of renovation and acceptance of property companies, Gas Co have acceptance gas equipment will be changed. Wait until after the full acceptance of the Gas Co will conduct ignition test.
- Q: My family is a new transformation, from the gas meter interface myself with a pipe should be connected to the Kai Tai Feng stove position pipe, but walk when there is a plane next to the flue ditch, and then buried brick in the wall do not know if there is no security risksIf you need to change, along the direction of the pipe to go down the pipe, with the water pipe package can be used?
- 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: How much is a cubic gas? Thanks for
- The quality of natural gas = natural gas volume x density, so the quality of a cubic meter of natural gas =1x0.7174=0.7174kg.Material weight = mass xg=0.7174x9.8=7.03052 cow
- Q: The gas stove bottom outside going black bag
- How to remove the bottom of the pot burning black how to do:You can go to the supermarket to buy some decontamination powder back, with a wet towel to wipe the pot clean. Or you can try to use plant ash, these are able to remove the bottom of this layer of black material. And now on the market some good work at the bottom of the pot, blackened by fire, as long as with a rag to wipe it clean, you can choose the pot.
- Q: What is the weight of a natural gas
- Natural gas has two kinds of state of compressed natural gas and liquefied natural gas, liquefied natural gas is 460-480kg cubic, compressed with pressure, the standard 20M is 0.71kg
- Q: At present, there is a gas cooker cooker does not want to buy a new cooker how to cook rice? Do not be too hard to do the Northeast
- The fire to boil a small fire, burning fifteen minutes (to the pot out Steamed Rice fragrance), stew for ten minutes (this is the key, not to open the lid, otherwise easy to Steamed Rice rawish).
- Q: What are the similarities and differences between liquefied petroleum gas stove and gas stove?
- The main components of natural gas is methane, combustion gas is less, so it needs more air, the air outlet of small and large air inlet, the main component of the liquefied gas is more hydrocarbons and olefinic carbon, and methane combustion is exactly the opposite, so the air outlet is larger.Calorific value of natural gas and liquefied petroleum gas, in particular, the gas stove nozzle, throttle, panel heat load and liquefied petroleum gas stove requirements are different, liquefied natural gas stove using natural gas, usually a small fireThe difference between liquefied gas stove and gas stove is the pressure, high pressure liquefied gas, natural gas pressure is low, reflected in the stove, the stove is liquefiers gas stove nozzle diameter smaller than the diameter of the nozzle, so two stoves can not be directly general.
