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:Formation of natural gasConcise, easy to understand,
Natural gas is mainly composed of C elements, is the remains of plants and animals in the earth's crust through complex changes
Q:Which gas pipes are not allowed to be buried?
Producer gas, water gas, semi water gas, blast furnace gas
Q:Why should the city's natural gas?
Natural gas has the characteristics of colorless, tasteless and inflammable and explosive
Q:Natural gas is how to find?
Between 6000 B. C. and B. C., Iran first discovered natural gas seeping from the surface of the earth. Many early writers have described the Middle East as a source of crude oil seeping from the surface, especially in Azerbaijan, Baku. The natural gas that had just begun to be used as lighting, the ancient Persians who worshipped the fire, had "never extinguished the torch."". The ancient Chinese people have a long history of the use of natural gas, in particular, through the drilling of oil wells combined with the exploitation of oil and gas technology, the world is also the earliest. Natural gas is a common oil. It's found time in salt well drilled simultaneously or later. 2000 years before the Qin Dynasty began digging well boiled salt gas. In the Jin Dynasty Chang Qu wrote "Huayang", a description of the Qin and Han Dynasties application of natural gas a few words: "Linqiong county has Huojing, night time on Zhao ying. The people want their fire, the first to cast fire at home. It was as loud as thunder, and out of the fire, and out of glory. The bamboo Qihuo Tibet can Sheng, pull the line out is all day long...... From the well cooked, a water bucket of salt five. A cook, too little too." Learned that as early as 2000 years ago, people used bamboo filled with natural gas, when the torch through the night. And with natural gas boiled salt, fire than ordinary firepower, salt is much more.
Q:Burn natural gas cheap or burn cheap, how to charge natural gas
1 meters fand natural gas prices in the 2.9~3.2 yuan / m of natural gas in different regions of fand, different prices.Electricity prices in the 0.50~0.8 yuan / degree, the price of 11.09 degrees between 5.5~8.8 yuan.It is obviously cheaper to use natural gas, the use of natural gas costs about 45% of electricity.
Q:For the development trend of natural gas? And cognitive level: why do people have a great deal of knowledge about natural gas?
Natural gas is a fossil fuel, but the exploitation and utilization of natural gas is still a lot of time
Q:How many cubic gas is a gas tank?
The liquefied gas residual liquid, temperament also have some problems, but also easy to Duanjinqueliang, according to the user's actual reaction can be cheaper 2/3
Q:How to prevent gas explosion
6, forced air supply furnace, such as a sudden power failure blower, resulting in gas reflux, there will be an explosion.7, coke oven gas pipeline has been blowing plastic equipment, and inspection, if the residence time is long, the accumulation of material within the device heating volatile, especially naphthalene sublimation of mixed gas and air to reach the same fire explosion, explosion.8, the burner is not strict, gas leak furnace, before the ignition is not on the furnace ventilation treatment.
Q:How much is a liquefied natural gas?
The volume expansion ratio of liquefied petroleum gas is about 260 times. 260*30=7800L. Liquefied petroleum gas calorific value of about 25000 kcal per cubic meter, the calorific value of natural gas is about 8500 kcal per cubic meter. 7800* (25000/8500) =22941L. It's probably not the use of heat.
Q:What is the standard unit of natural gas?N cubic meters; S cubic meters; and what is the difference between cubic meters?There is no one answer to the.Nm3, is the standard atmosphere, zero perturbation when the volume of gas, which is the international standard; M3 is the standard of China, sometimes written as [M3 (CHN}=], is the standard atmosphere, the gas volume of 20 perturbation);
If the points carefully, cubic meters is the measurement of the operating conditions, such as the above example, the pressure to 200 kg or so, only about 18 cubic meters of natural gasThe conversion of working conditions and standard conditions is based on the PV= nRT gas equationS cubic meters, S generally refers to the second, is not Nm if it is fand /S? This is the flow of sweat!
