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:Gas or gas is a general term for gaseous fuels
2, natural gas (T)The main component is CH4, there are a small amount of unsaturated hydrocarbons and CO2, N2, O2 and so onDivided into five categories: 4T, 6T, 10T, 12T, 13T.10T, 12T, 13T rated pressure of 2000Pa, 4T, 6T rated pressure of 1000Pa;Vanward's products are mainly 12T, 13T. currently has basically not 13T production, the so-called natural gas is currently mainly refers to 12T products
Q:I would like to ask the working principle of gas stove timer
(1) in the working state of the cooker, the timer timing function can be activated by pressing the upper adjusting key or the adjusting key of the timer. (2) press the button to adjust or adjust the key to set the timing, timing range is 1 minutes -9 hours and 59 minutes. (3) each press button to adjust or adjust the keys at the same time, digital increase or decrease the value of 1; (for example: the need to set the timer for 10 minutes, to press the button to adjust the 9 times) when the pressing adjustment button or down button to adjust the time more than 1 seconds to let go when the numbers are continuous with 1 units of rapidly increasing or decreasing. )
Q:How to do natural gas leakage
Do not put flammable and explosive articles around the gas stove, do not put heavy pressure on the gas pipeline. It can be used to check whether the leakage of the stove, the pipe and the connecting hose. Put the soap water on the outlet hole of the stove, or the connecting port of the pipe, the hose and the cooker.Should pay attention to, don't hang dishcloth, natural gas pipeline in the wet towel wet goods. For a long time to put these wet clothes, the pipeline is easy to rust, but also broken. A wet rag with salt or acid can also corrode iron pipes and shorten the life of pipes.
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
Q:What is the difference between natural gas and coal gas
What is the difference between the two gases, why is the gas better than the gas
Q:Natural gas toxic how should pay attention to
So, natural gas and liquefied petroleum gas is absolutely safe? Otherwise, carbon monoxide poisoning can occur if it is not used properly, because the gas is oxidized during combustion. When in a closed room, excessive consumption of oxygen, the gas will not burn completely, resulting in carbon monoxide poisoning. Therefore, the use of any gas should pay attention to ventilation, to prevent poisoning.
Q:How to do out of yellow fire in natural gas stove
Several causes of yellow fire and corresponding solutions are as follows:1, a lack of air supply, leading to bad combustion.Solution: the user can adjust the throttle plate, add air inlet area to solve, generally can make the flame from yellow to blue.
Q:What's the difference between propane and gas?
Coal gas: a combustible gas that is produced from coal as raw material. According to the nature and use of gas processing methods, divided into: coal gasification is the water gas and semi water gas, air and gas (or gas), the gas heating value is lower, so it is also called low calorific value gas; gas coking coal carbonization method called coke oven gas, blast furnace gas. The utility model relates to a medium calorific value gas, which can be used as a fuel for the city. Carbon monoxide and hydrogen gas are important chemical raw materials.
Q:How much is the gas in the gas tank?
General air compressor, is usually used in the general 8-13 atmospheric pressure. However, there are hundreds or even thousands of atmospheric pressure air compressor. You use air compressor gas, to be optimistic about the air compressor instructions, and then have pressure display table. Do not exceed the rated pressure range of the gas tank
Q:Where is the source of natural gas in China
According to the state of natural gas reserves, it can be divided into three types: structural natural gas, water soluble natural gas and coal gas. The structure of natural gas can be divided into crude oil produced by the wet natural gas, and does not contain liquid components of dry natural gas.
