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:How to safely use the gas?
- First, the use of gas should pay attention to what?The use of gas must pay attention to whether there is a smell, to ensure no leakage and then use the fire, and pay attention to ventilation should be good.
- Q:Sunday and her husband with a big clean-upThere is a lot of oil pollution in the gas stove, so scrub it with waterThe results can not be washed after the fireThe gas is out of breathHow to solve? Please advice!
- The following analysis does not fire the solution:When the stove eyes water, then come down to the water to dry, or dry with hair dryer, hanging on for half a day, and confirm the water, trying to strike, if still play, can also use fire to try to open, if not then it is to see if the following problems.
- Q:How much is a natural gas in 2014?
- Civil gas city gas prices are not the same, the specific price is mainly based on their own costs
- Q:What is the density of natural gas
- 4 calorific valueCalorific value refers to the standard 1 cubic meters of a certain amount of gas completely burned out of the heat, belonging to the characteristics of the material, the symbol is Q, the unit is the joule per cubic meter, the symbol is J/m3. Calorific value of high calorific value and low calorific value two.High calorific value refers to a standard cubic meters of gas after the complete combustion of the flue gas is cooled to the original temperature, and the water vapor in the condensed water discharged from the state of heat.Low calorific value refers to a standard cubic meters of gas after the complete combustion of the flue gas is cooled to the original temperature, but the water vapor in the flue gas is still the state of the heat released. The high calorific value of gas is larger than its low calorific value, and the difference is the latent heat of vaporization. Because natural gas is a mixture of gases, different components and different proportions of the components will have different calorific value,
- Q:Gas or gas is a general term for gaseous fuels
- 3, artificial gas (R)There are two main methods:One is the raw material of coal or coke into the industrial furnace in the combustion, and pass into the air and water vapor to generate combustible gas;Or isolated air heating, so that the occurrence of physical and chemical changes in coal, heating can be made after the purification of the gas can be obtained tar, ammonia, crude benzene and other chemical productsMain ingredients: H2; CO; CH4; C2; N2; CO2.Divided into three categories: 5R, 6R, 7R, rated pressure of 1000Pa.
- Q:For the development trend of natural gas? And cognitive level: why do people have a great deal of knowledge about natural gas?
- Natural gas is a fossil fuel, but the exploitation and utilization of natural gas is still a lot of time
- Q:Why is the gas burning black? Is it a gas or a gas cooker?
- Oh, my family's gas is still so, wash the pot all those who died. Looking for people to see, basically do a good job, the following list a few questions, you refer to the next.
- Q:How to do gas pipe leakage
- Telephone alarm. Where there is no gas leak, call the police.Found that the pressure regulator, pressure regulator cabinets, underground gas pipelines, such as leakage of gas, gas appliances should be closed immediately, plug valves, ball valves, cut off the gas source, put out the fire. Where there is no gas leak, call the gas company.Power off. Remember to breathe that fire off. Should immediately close the plug valve, ball valve. If the plug valve, ball near the flame, the use of wet towels, wet clothes wrapped hand, try to close the valve. Try to extinguish the fire. Use of fire extinguishers, wet quilt beat the flame. Evacuation personnel. (4) telephone alarm.
- Q:Is the gas escaping from the pipe floating up or down?
- Because natural gas is lighter than air! So go up! ~
- Q:Want to install a detection alarm, but do not know whether it is installed on the ground floor or ceiling?
- On the ceiling.Because the main component of natural gas is methane, the molecular weight is 16, and oxygen is mainly nitrogen and oxygen, molecular weight is about 29.Therefore, the density of natural gas is smaller than air,So natural gas is heavier than air!
