insulation paper
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:Gas stove gas, but can not beat ~ urgent
- Should be embedded stove bar, the battery installed it?If so, should be the battery power is not enough, so the solenoid valve can not open, gas can not enter the burner. A good pair of batteries will solve the problem.
- Q:When you find the home gas leak, you will immediately take the approach is ()A. open exhaust fanB. close the gas valve, open the doors and windowsC. immediately hit 119 alarmD. water the house so that the gas is absorbed by water
- C, when the discovery of the gas leak at home, we must first take measures to help themselves, when they can not help themselves to call 119, so wrongD, the main component of the gas is carbon monoxide, carbon monoxide is difficult to dissolve in water, to the house watering everywhere, it is difficult to make the gas absorbed by the water, can not prevent gas poisoning, so wrongSo choose B.
- Q:I would like to ask the electric water heater is good or good gas
- Purchase water heater to consider the price, safety. Convenience, life, cost, after-sales service and other factors. In recent years, some manufacturers in the product when consumers want to buy a pompous, satisfactory products, we need to know more about, more and more analysis.In general, the advantages of gas water heater is low price, fast heating, water, temperature stability, the disadvantage is that the room must be installed, it is not easy to adjust the temperature, the need for regular scaling, easy to produce harmful gases in use. Currently on the market 5 liters of the following products have been basically eliminated, more than 6 liters of products gradually become mainstream, some products even reached a total of 9 liters, up to 10 liters. According to experts, due to the residents of the home water pressure is different and the pipeline is basically the main reason for the 4 charge, the purchase of 6 liters / minute of water is the most suitable product. Because even bought 8 liters per minute or more products, due to pipe diameter and pressure limit, water can only reach 6 liters / minute level in most of the family, not to mention in most families, the actual use of the water inlet pipe and water outlet pipe can not guarantee all reach a diameter of 4 in charge of the inner wall the level of 6 liters per minute, so even the water is not up to (this is the electric water heater is also applicable). Again, the purchase of gas water heater according to their own use of the environment, there is a difference between the choice of flue type or strong platoon products
- Q:After their detection, leading to the gas tank and gas stove pipes are normal, I have to pull down the gas stove pipe open gas tank valve is out of gas, but a plug there are popping fire sound not out, hit when the nose smell gas, the battery should have electricity. That, when there is a sound and spark ignition. Unless the next three or four days can be the name, the name of a hit after the fight! Another three or four days and so on! I don't know why! Online master answer
- The other is the electromagnetic valve is broken, because Vatti uses a single solenoid valve, so after the failure of the solenoid valve on both sides of the electric power can not be normal ignition, looking for aftermarket replacement solenoid valve can be
- Q:Civil gas tank fire, the best way to fight fire?
- The gas tank on fire is not to shut the valve! Can be used when dots. Put out to shut the valve. Otherwise easily lead to explosion!!! On the application of water cooling, the fire quickly extinguished, and then close the valve. This is my safety class to fire the instructor said, have seen the pipeline leakage fire rescue, really, was very puzzled, why not put the valve off first, after that you pay attention to ah!!!
- Q:Ditto, or the history of the development of China's gas; thank you
- June, Qinhuangdao to Beijing oil pipeline was completed in December 27, 1974, Daqing to Qinhuangdao oil pipeline has been completed and began to oil, so far, Daqing oilfield crude oil directly to Beijing. In July, the oil wells of the 4 well in the Gulf of Bohai were ejected from the ancient volcanic rocks in the carbonate rocks. 17 months, Changchun coal gas plant completed and put into production. July 3rd, Hebei, Renqiu hit a high-yield wells, found in Renqiu oilfield.
- Q:My family is several times a month, ah, I only two people.
- Your home is not a general, our four large and small, electricity is 300 yuan for two months or so, the air conditioning is not the peak, if the summer is 600 dollars for two months, two months of 100 water, gas pipeline is also used, cooking and bathing, a month is probably around 80, in addition my home soup is electric home appliances are not many, two Taiwan two, two Taiwan computer, washing machine, refrigerator air conditioning on each one, we opened the room more
- Q:What is the difference between the cooker and the gas cooker
- The biggest difference is that the induction cooker is the use of high-frequency magnetic field generated by the eddy current in the magnetic field on the bottom of the pot to produce heat, so the cooker must be made of magnetic metal. The gas pot is directly heated by fire, so it does not need to be guided.
- Q:How do I open the valve, or no gas ah?
- Each gas stove is not the same, when it has been open until the fire will not be extinguished, when the counter clockwise rotation can not be pressed to open the switch to press
- Q:Why is the gas plant often mixed with a small amount of gas in the household gas (mainly carbon monoxide)? What happens if there is a gas leak? How to prevent gas poisoning?
- The gas is flammable, contact fire or electric spark may explode if the gas leak should turn off the gas valve immediately, open the doors and windows for ventilation can reduce the indoor temperature, and dilution gas, to prevent explosion.
