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:What is water gas?What is the principle?
The overall chemical equation is: H2+CO+O2= ignites =H2O+CO2 (hydrogen and carbon monoxide and oxygen react to produce water and carbon dioxide in the presence of light)Combined with chemical formula: H2O+C= =H2+CO= =H2O+CO2 (high temperature light steam and hot coke first reaction at high temperature under the conditions of hydrogen and carbon monoxide, hydrogen and carbon monoxide in the light conditions to produce water and carbon dioxide).Short chemical equation is: H2O+C+O2= high temperature / ignite =H2O+CO2 (water vapor and hot coke and oxygen to generate water and carbon dioxide at high temperature, ignited conditions)
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:When you find the home gas leak, you will immediately take the solution is
C, when the discovery of the gas leak at home, we must first take measures to help themselves, when they can not help themselves to call 119, so wrongD, the main component of the gas is carbon monoxide, carbon monoxide is difficult to dissolve in water, to the house watering everywhere, it is difficult to make the gas absorbed by the water, can not prevent gas poisoning, so wrongSo choose B.
Q:Why does the gas smell?
Generally, the main components are carbon monoxide gas burning stove in winter. When the doors and windows closed, the room is not ventilated, produced carbon monoxide can not spread to go outside, people suck more will carbon monoxide poisoning. There is no color, no smell, be inhaled, through the alveoli into the blood, and is responsible for transporting the first oxygen binding to hemoglobin in red blood cells
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:Do you have natural gas
Gas online to answer you:Gas online for users: once in 273 Zong dying brother, answered a similar problem, in which I put my answer to you move:
Q:How can we prevent the gas tank from exploding? What is the power of a household gas tank?
The use of gas, there must be sitting in front of the stove, or go out every day before going to check the gas valve is closed. The qualified product gas tank should choose the regular manufacturers of products, and the professional team to regulate the installation. Please use the gas tank, to maintain good indoor ventilation, to prevent gas poisoning
Q:When the family's natural gas cooking, do not open the opportunity to produce fumes fumes?
That is because urban residents use piped gas, carbon monoxide concentration in the pipeline of 25% to 30%, if the pipeline leaks
Q:How does natural gas exist underground?
Natural gas is a kind of mixed gas which is the main body in the underground rock reservoir. Including oil field gas, gas field gas, coal bed gas, mud volcanic gas and biological gas. The main component is methane, usually 85-95%; followed by ethane, propane, butane, etc.. It is a good fuel and chemical raw materials. The gas is usually volatile fraction of crude oil, the gas exists in the form of reservoir, where there are oil formation, oil and gas are different proportion. Even in the same field of oil and gas sources are not necessarily the same. They are collected from different pathways and different processes in the same reservoir. If you are a non associated gas and liquid concentration independent, may be produced in plant material. The world's natural gas production is mainly gas and gas. The exploitation of coalbed methane has been paid more and more attention.
Q:Why can't a gas stove use natural gas?
Natural gas and artificial gas are two kinds of gas with different properties, and their calorific value, flame propagation speed, gas pressure and composition are all different. Natural gas is generally dry gas, the main component of methane, basically no impurities, high calorific value, slow flame propagation speed, high delivery pressure. The artificial production of coal gas is a mixture of gases, containing water, oil and dust, ammonia naphthalene, hydrogen sulfide and other impurities, lower delivery pressure.
