Glass micro fiber cryogenic

Cryogenic insulation paper/radiation shield compositions:

Cryogenic insulation paper(P paper/Z paper)/aluminum foil(or aluminized polyester film) compositions are laminated of Cryogenic insulation paper and aluminum foil(or aluminized polyester film).These products can be wrapped to the cryogenic inner tank directly and no need to composite by user. Therefore ,it can effectively reduce the waste of material and hugely increases efficiency. The width varies from 40mm to 1800mm.

Q: How does natural gas exist underground?: In the total amount of resources, the Cenozoic accounted for 37.3%, Mesozoic group of the upper Paleozoic, the upper Paleozoic of the world, the lower Paleozoic of the year 25.5%, 26.1%. The genetic type of natural gas resources, high maturity of the pyrolysis gas and coalbed methane dominated respectively of the total amount of resources 28.3% and 20.6%, oil gas in coalbed gas accounted for 18.8%, accounted for 27.6%, accounting for 4.7% of biogenic gas. Chinese natural gas reserves are concentrated in 10 large basins, followed by: Bohai, Sichuan, Junggar, Songliao, Yinggehai and Qiongdongnan, Qaidam Basin, Turpan, Tarim, Bohai, Ordos. The gas fields in China are mainly small and medium, and the geological structures of most gas fields are complex. 1991-1995, China's natural gas production increased from 16 billion 73 million M3 to 17 billion 947 million m3, with an average annual growth rate of 2.33%.

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: What are the hazards of adding two methyl ether to gas?: Two (DME) is a colorless gas with a slight ether flavor, the vapor pressure at room temperature is about MPa, which is similar to the physical properties of liquefied petroleum gas (LPG) (). Two dimethyl ether with inert, non corrosive, non carcinogenic, almost non-toxic. Unlike two ethyl ether, the long term exposure of methyl ether to air in the presence of two. Two ether saturated vapor pressure is lower than the liquefied gas storage and transportation, safer than liquefied petroleum gas, and combustion performance, high thermal efficiency, combustion process without residue, no black smoke, CO, NO emissions low, two DME has also mixed with liquefied petroleum gas, coal gas or natural gas combustion and can improve heat two, more than 95% ether can be directly used as fuel instead of liquefied petroleum gas. Therefore, it may be an ideal clean fuel to replace lpg. In addition, the two can also be used as chemical raw materials, mainly used in the manufacture of spray paint, pesticides, air fresheners, hair gel, anti rust agents and lubricants, etc..

Q: 1 inch water gas pipe diameter: Inside diameter 25.4mm, outside diameter to see is standard, thin wall or thick wall, standard 32mm.

Q: When the family's natural gas cooking, do not open the opportunity to produce fumes fumes?: I am learning natural gas in this regard, it can be said that the probability is too low, the gas poisoning we previously estimated that often heard

Q: How to do natural gas leakage: If you find a gas leak, to keep calm, take the right solution to avoid the explosion. First of all, the gas valve should be closed immediately, blocking the gas source; and quickly open the doors and windows ventilation, action should be kept in mind, so as not to cause the explosion caused by heavy metal impact. Can not be anxious panic, if accidentally hit the metal objects indoors, may also produce sparks and explosion

Q: What are the classification of natural gas: According to the classification of natural gas can be divided into: free gas, dissolved gas, adsorption gas and solid gas;Classification of natural gas by economic value can be divided into: conventional natural gas and unconventional natural gas

Q: The gas stove was able to hit the fire, but once it was released, it began to bounce again: Ignition principle: open the gas stove -- white "ignition needle" issued red arc (Charlie para ring Mars) and heat - "thermometer" temperature - pulse ignition.

Q: The working principle of the gas refrigerator?: The ammonia is absorbed by dilute ammonia water and becomes a concentrated ammonia solution. So coalThe utility model is characterized in that the air refrigerator is heated by gas combustion, and the three substances of ammonia, water and hydrogen can be recycled in the pipelineMinimum temperature of minus 40 degrees C.

Q: Do you have natural gas: When used for the sake of safety in the family, in the natural gas added a smell agent, so that when the gas leak will smell the smell, be aware of.If the home is not sensitive to the smell of the elderly or children, it is recommended to install a household gas alarm, as far as possible to choose a qualification, a certificate, a professional insurance gas alarm.
