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:Liquefied petroleum gas and gas
Coal gas is made of solid raw materials, such as coal or coke, which is prepared by distillation or vaporization. Therefore, the toxic gas, easy to form explosive mixture of air, should be used when a high degree of attention.The term "natural gas" refers to the natural gas formed in the 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 field. Natural gas from organic substances into the hundreds of millions of years ago. 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 also contain helium gas. Natural gas is an important energy, widely used as city gas and industrial fuel.
Q:Why does the gas smell
So where does the gas come from? When coal is burning in the stove, air enters the furnace from the lower part of the furnace. As a result, the following carbon can get sufficient oxygen, burn completely, produce carbon dioxide, and produce a lot of heat. It is easy to produce gas when the combustion is incomplete. For example, just lit the stove, or the fire was extinguished, or when the door is closed due to fire, the temperature is relatively low or insufficient supply of oxygen, the combustion is not fully, will produce gas.
Q:Liquefied gas and coal gas _?
Propane and butane are very easy to burn. However, if the propane, butane gas installed in the cylinder, can not be installed in a few minutes to use up. The utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that. When in use, as long as the valve is turned off, the pressure is reduced, liquefied petroleum gas is continuously turned into a gas, and can be used as a gas.
Q:Is natural gas solid?If so, under what conditions will become solid?
Natural gas hydrate is a kind of white solid substance, which is like ice and has strong burning power. It is mainly composed of water molecules and hydrocarbon gases (mainly methane), so it is also called methane hydrate. Natural gas hydrate is in certain conditions (the appropriate temperature and pressure, gas saturation, water salinity, pH etc.), solid white crystalline substance formed by the interaction of gas or volatile liquid and water in the. Once the temperature rises or the pressure decreases, the methane gas escapes and the solid hydrates tend to disintegrate. (1 cubic meters of combustible ice under normal temperature and pressure can release 164 cubic meters of natural gas and 0.8 cubic meters of fresh water) so permafrost gas hydrate solid are distributed in the water depth of more than 300 meters above the seafloor sediments or in the cold. Natural gas hydrate on the thick layer of pressure to maintain its solid state, its distribution from the seabed to 1000 meters under the seabed within the range, deeper temperature due to its solid state is destroyed and difficult to exist.
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 to distinguish artificial gas, natural gas, liquefied petroleum gas
1 liquefied petroleum gas pressure 2.8KPa, gas supply is generally very individual cylinders, for gas pipeline, a symbol of 20Y, liquefied petroleum gas outside the box and the nameplate for all parts of the country have the type of the gas source and application delivery area, should pay attention to check, to avoid the wrong goods.
Q:The industry's natural gas consumption benchmark is 10GJ/ tons, GJ what is it?
Tg=terrogram=10^12g or million tons, often used to describe the amount of gasGL is a gallonGJ means G joules, energy units, 1000 times the focal MJ
Q:How long can you boil water on a gas stove with a kettle?
Your question is not very detailed, so no one gives you a very precise statement
Q:The nature of blast furnace gas
Two, physical and chemical properties and hazardous characteristics of converter gas:The physicochemical properties of 1, converter gas mainly depends on the gas composition, gas properties of different components of different, inflammable and explosive, easy poisoning is one of the three major characteristics of gas poisoning, fire and explosion. Often referred to as the three gas accidents.2, converter gas is a flammable and explosive gas, carbon monoxide explosion limit is 12.5 74.2%. mixed with air can form explosive mixtures, in case of fire, electric spark, high temperature above 650 degrees and glowing metal objects will cause combustion and explosion.3, converter gas is a highly toxic gas, the human body in a short period of time in contact with a large number of gas, will cause tissue hypoxia, so a long time in the gas area, carbon monoxide concentration should not exceed 30mg/m3 (24ppm)
Q:The gas in the gas tank is used up. What's wrong with the water?
Normal phenomenon, but the water can be burned, so when dealing with the water to pay special attention to the gas bottle water is usually due to the two cases
