foil back insulation paper  for lng cryogenic storage

The ordinary cryogenic insulation paper(incompatibility with oxygen):

Ordinary cryogenic insulation paper is made of a special process with high quality chemical fiber, usually compositely used with aluminum foil or single (double)aluminized polyester film. It is used in the storage container of cryogenic liquid(liquid helium, liquid nitrogen and liquid argon) and also used in dry ice storage vessels. Its advantage are lightweight, good uniformity, low thermal conductivity, large thermal contact resistance, low outgassing rate in vacuum. This product can be applied in a wide temperature range:-269°C-190°C.

Q:Liquefied natural gas water heater
Safety performanceAs long as the master technology principle, the correct procedure in accordance with the operating personnel with a serious and responsible attitude, after the completion of the transformation of the safety performance inspection of gas water heater, of course you don't have to worry about security issues, a qualified after the transformation performance does not occur naturally change, you can rest assured that use. But why there are still online netizens have said "my water heater transformation winter after the water is not hot enough, a small fire cannot catch fire, and water heater repair", we analyze the three reason is that the water is not hot enough mainly because of the transformation parameters did not have a good nozzle parameters are incorrect. A small fire when the water heater cannot catch fire mainly affect the parameters of gas valve core hole, a lot of reform personnel did not notice the valve hole parameters also need to be rebuilt, or know to change because of the influence is not big but deliberately do not change the trouble, in summer, they found a small fire to beat the fire off a small fire at lower temperature. Therefore, it is very important for the transformation to be transferred to the minimum firing position to meet the requirements of ignition performance. In addition, the summer temperature can not drop down can also be tested through the smallest firepower, timely solution! Finally, it is clear that the liquefied natural gas water heater can be changed into natural gas, the natural gas water heater is also feasible to transform into liquefied petroleum gas! Shenzhen in the use of natural gas water heater 70% is the transformation of the new purchase of the 30% (to buy the use of natural gas).
Q:Why does the gas smell
Some people put a basin of water in the room or a pot of water on the stove, that can absorb carbon monoxide, this is wrong. Because carbon monoxide is insoluble in water. To prevent gas poisoning, it is necessary to put a chimney on the stove, so that the gas through the chimney to the outside. The other is the best in the window above a scoop, maintains the indoor air circulation.
Q:What is the density of liquefied petroleum gas
The main component of alkane gas, including methane, majority, and small amounts of ethane, propane and butane, in addition there are hydrogen sulfide, carbon dioxide and nitrogen and water vapor and a small amount of carbon monoxide and trace rare gases, such as helium and argon.
Q:Three advantages of using gas
Three advantages of gas: 1 flammability2 foot Fire 3 cleaning
Q:Which is more important, natural gas and air?
Natural gas is stored in underground porous rock, the main component of methane, the proportion of 0.65, lighter than air, with colorless, tasteless, non-toxic characteristics
Q:When you find the home gas leak, you will immediately take the solution is
B, a gas leak, the ventilation window, make indoor air convection, the concentration can reduce the temperature of the gas and reducing the combustible gas, the mixed gas is not up to the fire and explosion limit, so right.
Q:Is it okay to turn off the gas stove after using the gas?
2, regular replacement hose. According to the relevant provisions of the gas safety management and technical specifications, should be replaced every two years hose. Due to the quality of various brands of rubber hose, in order to the user's own safety, it is recommended to replace the hose once a year, the user should be aware of this point. The following points should be paid attention to when replacing the hose:(1) when the hose is connected, a special air nozzle joint shall be used, and then the throat code is used to fasten the hose.(2) hose length should be less than 2 meters. Hose shall not produce bending, stretching, foot and other phenomena. Cracked, aging hose shall not be used.(3) hoses shall not be installed in the following locations: where there is a flame and radiant heat. Hose, not across the windows, put off the wall using the house.
Q:How to adjust the gas stoveMy home is a liquefied gas stove fire is yellow no sound
How much air conditioning, in the stove under the two iron, toggle regulation. One is to control the inner ring of fire, an outer ring of fireLet the flame as far as possible blue, do not appear the sound of whirring
Q:How many cubic metres of gas is a ton of coal
Calorific value of coal by 5100 kcal /kg, natural gas of 8500 kcal / cubic,A ton of coal is approximately equal to 5100*1000/8500=600 cubic meters of natural gas
Q:How to buy range hood and gas stove
The hood with its beautiful appearance, good smoke exhaust effect, can be matched with different styles of kitchen furniture decoration, moderate price and other characteristics, as the family will share the kitchen appliances. However, consumers buy hood, if you do not grasp the more basic methods, to point, it is easy Cairu optional errors here, on the five aspects of the analysis, I hope to help you get the heart, the right products to a certain extent
