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: What pipe used in indoor natural gas pipeline
- As long as 4843km of the west east gas pipeline line using 1219mm diameter of X80 steel pipeline steel, the gas pressure increased to 12Mpa. Generally speaking, X80 steel is ferrite and bainite dual phase structure, X100 pipeline steel is bainite structure, X120 pipeline steel for ultra low carbon bainite and martensite. For the pipeline of natural gas pipeline, strength, toughness and weldability are three basic quality control indexes
- Q: Does the electronic ignition gas stove need the battery?If the battery needs to be replaced?If you do not need a battery, that is what the principle of ignition, has been able to use it?
- With the kind of flameout protection with two batteries (fire cover with two needles), battery power consumption is larger, not durable, the general battery in March to about 6 monthsOn the fire cover with one ignition needle without flameout protection, with a battery, will be relatively more durable for 6 months to 1 years, when the ignition needle can make fire can not continuously "Da Da" ignition, electric strength is obviously insufficient, then it is difficult to ignite the fire source to replace the battery.
- Q: Gas stove has been broken fire is how
- There are many reasons, 1, the throttle did not adjust well, you can adjust the throttle to the flame burning ideal can be,
- Q: How much is a gas tank empty?
- I bought an offer last year is 55, then the counter-offer is only a quick money ah, only 45
- Q: How does the conversion of natural gas from cubic to ton? Do you need the same data as density or pressure?
- Natural gas per ton:1000/0.7192 = 1390 cubic metersThe above algorithm is more accurate, but too cumbersomeI can introduce a simple estimation method for any gas, but not very accurateIt is known that the molecular weight of water molecules is 18 and the density is about 1 kg / LUsually converted to liquid or solid gas and gas that is at 20 degrees and a standard atmospheric pressure, the volume of about more than 1000 times, and specific to the water is about 1200 times. It is in 20 degrees, a standard pressure water vapor volume of 1.2 cubic meters.This 1.2 cubic meters of water vapor is from a liter of water (a kilogram) to change, so the water vapor density: 0.8333 kg / cubic meterThe density of natural gas:Molecular water vapor density * gas molecular weight, the amount of water=0.8333 * 16 18=0.7407 / kg / m3
- Q: Liquefied petroleum gas cylinder in the home after the valve has been a big fire, gas stove by adjusting the basic do not work, so I want to adjust the pressure relief valve, but I have a half twist counterclockwise, little effect. Do not dare to twist, special to help the general number of twists and turns to see how the effect?
- You're in the wrong direction! Pressure valve is generally the factory debugging good, do not deliberately tune it. If there is a need to adjust the words, different valves have different adjustment method, and some with a screwdriver, and some direct adjustment by hand, mostly the same principle. When the pin is decompression, counter clockwise is booster. That is, when the pressure is small, when the pressure is relaxed. If you are not sure, you first clockwise twist a circle, look at the results, and then back to a circle to the original twist. At this time, counterclockwise turn a circle and then look at the effect of this contrast, you can get results! Wish you well!
- 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: Gas stove gas, but can not beat ~ urgent
- Three ring, 555, deer, elephant, leopard, train, Nanfu, Changhong, Wang Zhenglong, Mustang battery is good, you can use the time.A lot of customers mistakenly believe that spark is the battery power, in fact, this is a different thing.
- Q: How can we prevent the gas tank from exploding? What is the power of a household gas tank?
- X0d when the gas tank leak, should keep calm, immediately shut off the gas valve, is strictly prohibited in the indoor open all kinds of electrical equipment, such as lights, telephones, etc.
- Q: Natural gas pipeline is how to connect the seal? How to do not leak
- The utility model is connected through a flange and is fixed by bolts, and the middle part is provided with a cushion, a graphite winding or a metal winding
