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:Stainless steel pots and bowls can be placed on the gas burning? Will explode?
Black marks are hard to remove. So, as far as possible without the pot of stainless steel bowl directly on the fire to cook hot meals. Or use the pot with normal hot dishes better.
Q:What's the difference between propane and gas?
Propane: three alkane, the chemical formula is C3H8, usually gaseous, but generally compressed into liquid transport. Crude oil or natural gas can be obtained from the finished product. Propane is commonly used as fuel for engines, barbecue food and domestic heating systems. In sales, propane is commonly referred to as liquefied petroleum gas (LPG). In order to avoid accidental leakage, commercial liquefied petroleum gas is generally added to the stench of mercaptan.
Q:How natural gas is formed
The oil and natural gas generation process have both similarities and differences: the oil is mainly formed in the catagenetic stage, caused by catalytic cracking, and the formation of natural gas passes through the diagenesis, plutonic metamorphism, after until the beginning
Q:What are the symptoms of inhaling gas
The family of gas poisoning mainly refers to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas, natural gas poisoning, the former is more common in winter heating coal stove, doors and windows closed, smoke is poor, which is common to liquefied gas pipeline leak leak or stove. Gas poisoning patients initially feel headache, dizziness, nausea, vomiting, weak and feeble, when he realized the poisoning, often struggle out of bed to open the door, open the window, but only a few people can open the door, most of the patients rapidly pumping spasm, coma, cheeks, chest skin and lips of cherry red colour, if the treatment is not timely. But soon died of respiratory depression. According to the concentration of carbon monoxide in the air and the time of poisoning, gas poisoning is usually divided into three types:
Q:Liquefied petroleum gas, artificial gas, the calorific value of natural gas
The gas from coal or coke and other solid material, through carbonization or vaporization was prepared, its main components are carbon monoxide, methane and hydrogen. Therefore, toxic gas, air to form explosive mixtures, use should be paid attention.Natural gas general refers to buried in the earth's natural gas formation. But usually called natural gas only refers to a flammable gas rich in hydrocarbon storage in deeper strata, and natural gas and oil symbiosis is often called the oil gas. Natural gas from organic substances into the hundreds of millions of years ago. Here, the main component is methane, formed according to different geological conditions in addition, still containing different amounts of ethane, propane, butane, pentane, hexane and other low carbon alkane and carbon dioxide, nitrogen, hydrogen sulfide and other non hydrocarbons; some gas also contains helium. Natural gas is an important energy source, widely used city gas and industrial fuel; in 70s the world energy consumption, natural gas accounted for about 18% ~ 19%. of natural gas is an important chemical raw material.The calorific value of gas per cubic meter is 8000 kcal to 8500 kcal
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:There is a gas range, not connected to natural gas
You should be built, is a portable stove for filling butane gas as the main fuel.
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:What is the weight of a normal bottle of gas?
If users find bottled gas Duanjinqueliang, can reflect the complaints to the quality inspection department. In addition, taking into account the safety issues such as air pressure, inflation can not be exceeded, with a maximum of 14.9 kg.
Q:Why don't you turn on the lights and call the gas leak
But these spark temperature is not low, once ignited in air gas, is caused by the explosion (do you have a light bulb will burst through, then not only spark may even produce arc, if such a thing happened, in a room filled with gas consequences as can be imagined)
