cryogenic thermo-insulation material

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: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 do you see the gas stove with gas or gas?
How do you see the gas stove with gas or gas?Zhn0908 | browse 2486Recommended 2016-12-01 20:19:18 best answerNow there are three kinds of household gas, respectively, artificial gas, liquefied petroleum gas and natural gas, in the national standard, their code names are R, Y, T. There is a very common situation in many parts of the liquefied petroleum gas or natural gas or gas, this was an opportunity to change the concept of small businesses.
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:Home improvement gas pipe material
3, aluminum tubeThe inner layer and the outer layer plastic tube is a kind of special polyethylene material, non-toxic environmental protection and quality of light, the nature "is very suitable for application can take temporary setbacks" in the home decoration. But as aluminum pipe of indoor gas pipe, can withstand the pressure of work, but also because the pipeline can be extended for a long distance, need the joint is less, so the gas permeability is almost close to zero. Using aluminum pipe owners as household gas transportation route is safe and reliable, but be careful to avoid buy inferior aluminum-plastic, because the market inferior aluminum pipe by the collision, easy bending, deformation, or even rupture, threatening the safety of life and property owners.
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 are the hazards of adding two methyl ether to gas?
In fact, two is a clean energy, it can be used as fuel
Q:How to do gas pipe leakage
1 easy to leak place: hose, interface, gas meter, plug valve, ball valve.2 when the suspect a gas leak, the leak using the following method: one of the optional soap, washing powder, detergent three, and water to form a liquid soap onto the hose, gas appliances, gas meter, plug valves, ball valves, especially at the interface, the bubble bulging part is the leakage point. The eyes, ears, hands touch, smell with the leak. (Note: do not use open flame leak.)
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:How many cubic meters of natural gas is equivalent to a tank of liquefied petroleum gas?
One survey:Natural gas consumptionHave the same calorific value consumption difference for a more clear understanding of natural gas and liquefied petroleum gas, the reporter first came to have completed the conversion of natural gas B4, 3B Lee Chui sea garden, the old lady's house, the use of natural gas heating effect test. The amount of the elderly cup installed 1000CC (cubic centimeters) of water, poured into a stainless steel pot, the reporter recorded the gas meter reading is 134.731 cubic meters. Then the old lady lit the fire and the fire to the maximum, heating time synchronization also started. When the whole pot of water to boil, gas meter reading 134.759 cubic meters. In other words, the use of natural gas cooking stove 1000CC water, gas consumption is 0.028 cubic meters. Subsequently, the reporter went to be Chui sea garden A4 block Geng old gentleman of the trial. The same pot, the same volume of tap water, gas consumption 0.031 cubic meters.
Q:How much do you spend on gas and water in a month?
Here we are saying about adult more also do not have to pay utilities, then pay system isolation neighbors once a year, just a heartache
