Product Description:

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:Natural gas toxic how should pay attention to
So, natural gas and liquefied petroleum gas is absolutely safe? Otherwise, carbon monoxide poisoning can occur if it is not used properly, because the gas is oxidized during combustion. When in a closed room, excessive consumption of oxygen, the gas will not burn completely, resulting in carbon monoxide poisoning. Therefore, the use of any gas should pay attention to ventilation, to prevent poisoning.
Q:How many cubic meters of gas does a ton of steam boiler produce a ton of steam
Per cubic meter of natural gas calorific value of 9000 kcal;Boiler thermal efficiency 0.91;It can be concluded that the boiler heat transfer index is 0.91x9000=8190,By 600000/8190=73.000,In other words, in theory, every ton of water vapor, need to consume about 70-75 square gas
Q:This morning, the new gas tank, after the change will not catch fire
Can reduce the pressure relief valve or a bottle of gas to try.
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:How much water can a cubic gas burn? emergency
The amount of heat required to boil a litre of water is 80 kcal, and the amount of the water is about 107.5 by dividing the number by a factor of 8600, which is about one cubic meter of natural gas, which is about to boil up to 107.5 liters of water.
Q:How much gas is equal to 1
1 cubic at any time equal to 1000 liters, as long as the temperature and pressure constant.
Q:How do you see the gas stove with gas or gas?
Look at the label, the cooker model format is usually:JZ * XXXXWhere JZ is a unified home appliance crown, when the back of the R is said to be artificial gas stoves, when Y is said to be liquefied petroleum gas stove, said T when the gas stove. XXXX behind the bar is the manufacturer's model, can not be ignored in the resolution of the gas source.
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!
Q:How to use the gas to burn the pot is very black how to solve it
The reason why the gas stove burns the torch pot is black:1, the stove stove head with carbon steel brush clean, need to find.2, is due to the long time no use, there are holes in the spider web block, you can take the stove under the pin, with small things through the spray hole, take out foreign body. The stove is installed after the name of a screwdriver, tapping the stove, is carbon fly, blue flame can be.
Q:How much gas to burn 1 tons of steam
Through the boiler equipment, passed to the changes of water absorption of heat medium water, physical properties, low temperature and high temperature water into water into steam gasification, it completes the process need to absorb the heat of about 600 thousand kcal of natural gas quality.
