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: Explain the cause of the expansion of the volume of natural gas after decompression
- The volume of a gas is related to the number of particles in the gas molecule
- Q: 0.3T gas steam boiler about one hour to burn a lot of natural gas
- 1 tons of boiler =60 kcal. 0.3T boiler =18 kcal,The calorific value of natural gas is about 8600 kcal, 0.3T gas steam boiler theory about an hour by 21 party gas, taking into account the actual utilization efficiency of boilers and boiler, steam boiler 0.3T gas per hour the actual gas should stand in 15-25.
- Q: How many cubic metres of gas is a ton of coal
- A ton of coal = one thousand kg of standard coal per kg of complete combustion of the release of the heat of kcal / ton of coal heat =1000 by 7000 kcal =700 kcal
- Q: The status quo of the world and China's natural gas
- Preliminary estimates, the world's recoverable reserves of natural gas is about 137 tons of oil equivalent, and basic oil equivalent. With the development of exploration, development and storage and transportation technology, proven reserves grew by an average of 4.9% annually over the past 20 years, with an average annual growth of about 3.15%. Experts predict that the next 10 years, the world average annual growth rate of natural gas consumption will keep 3.9% growth rate than oil, coal and other any kind of energy, especially in developing Asia's growth rate will be faster.The world's natural gas reserve production ratio is very high (70 to 1), and the oil and coal consumption in the field of more than 70% can be replaced by natural gas. In the global scope, natural gas to replace oil to speed up the pace, especially in Northeast Asia, South Asia, Southeast Asia and South America, with its natural gas pipeline network construction, in the early twenty-first Century will have a faster development.Natural gas will be the fastest growing energy consumption in twenty-first Century, accounting for the proportion of disposable energy consumption will be growing. It is expected that in 2010, the share of natural gas in the global energy structure will be more than coal, around 2020, will be more than oil, becoming the first in the composition of energy.
- Q: How to do gas pipe leakage
- 1 easy to leak place: hose, interface, gas meter, plug valve, ball valve.2 when the suspect a gas leak, the leak using the following method: one of the optional soap, washing powder, detergent three, and water to form a liquid soap onto the hose, gas appliances, gas meter, plug valves, ball valves, especially at the interface, the bubble bulging part is the leakage point. The eyes, ears, hands touch, smell with the leak. (Note: do not use open flame leak.)
- Q: How to use the gas to burn the pot is very black how to solve it
- 3, the mixed gas is not adjusted, the specific adjustment method: you can put the stove up, can see two holes and at the head of two iron in the following, a fire is a fire outside the door, can take two tablets are opened to the maximum position of the wind, the fire will be suspended or missing phenomenon too half a little off, can see the fire in the back, adjust.
- Q: The book is written in natural gas is colorless and odorless non-toxic gasHow do I smell the gas?And smell the dizziness is not toxic?Why write the book?
- Incomplete combustion, carbon monoxide. Smell the stench is added to the gas station, is non-toxic. The oxygen used in the combustion of gas is obtained directly from the air, and the oxygen in the air accounts for 21%. The original space in the kitchen is very small, in the use of natural gas, the oxygen used and the resulting exhaust gas on the oxygen shortage caused by excessive emissions of oxygen and space! Can lead to dizziness, vertigo, serious will affect the long-term brain hypoxia caused by nerve injury and suffocation! It is recommended that the use of natural gas to pay attention to the following points, 1 the use of natural gas must be ventilated at home.
- 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: What are the components of natural gas?
- Natural gas is a kind of multi component mixed gas, the main component is alkane, the majority of methane, and a small amount of ethane
- Q: Liquefied gas and coal gas _?
- Both of them are gas fuels, but they are not the same thing.Coal gas is made from coal. The main components of gas are carbon monoxide, hydrogen and methane. After the gas was born in the gas plant, it was stored in a large gas tank, and then ran down the gas pipe to your home. Therefore, only in the place where there is a gas plant, the laying of the gas pipeline in place, it is possible to use gas.
