Glass micro fiber cryogenic

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: Why can't a gas stove use natural gas?: Natural gas and artificial gas are two kinds of gas with different properties, and their calorific value, flame propagation speed, gas pressure and composition are all different. Natural gas is generally dry gas, the main component of methane, basically no impurities, high calorific value, slow flame propagation speed, high delivery pressure. The artificial production of coal gas is a mixture of gases, containing water, oil and dust, ammonia naphthalene, hydrogen sulfide and other impurities, lower delivery pressure.

Q: There are two gas cylinders at home, a long time no use, and one of them have been put down for more than a year... The bottom of the gas tank is out of paint.. Very worried! I don't know if it will be a problem I'd like to know a little bit about the knowledge! Thank you！: The gas tank is transportable pressure vessel steel, with explosion danger, it is only about 2.5 mm wall thickness (cylinder wall thickness calibration), very thin, it all the time under pressure from internal media generated during normal use of internal pressure (pressure) from 0.5 to 1 trillion and 200 billion Pascal ($from 5 to 12 kg / cm2), the cross section will be 1000 kilograms of tension.

Q: Liquefied petroleum gas, artificial gas, the calorific value of natural gas: People's lives in the combustion gas sources can be roughly divided into liquefied petroleum gas (Y), artificial gas (R), natural gas (T) three categoriesLiquefied petroleum gas (referred to as LPG) is a kind of oil gas remaining oil in refining gasoline, kerosene, diesel oil, heavy oil and other oil products in the process, through certain procedures, the oil exhaust gas recycle, take measures to make it into a pressurized, liquid, installed in the pressure vessel, the name of the resulting liquefied gas. Its main components are ethylene, ethane, propylene, propane and butane, a liquid in the cylinder, the combustible gas once the outflow will vaporize into about two hundred and fifty times than the original volume, and easy to spread, encountered the fire will burn or explode. Therefore, the use of liquefied gas also pay special attention to.

Q: Natural gas and air density which is higher than that that is when the gas leak upward or floating: The average relative molecular mass of air is 29. At the same temperature and pressure, the density of natural gas is less than that of air

Q: Why is the gas burning black? Is it a gas or a gas cooker?: First, due to insufficient intake, simply the stove door can be adjusted.Two, because the stove used for a long time, the large amount of blockage, will remove the stove clean can.

Q: Compare the advantages and disadvantages of the two kinds of fuel, honeycomb briquette and coal gas according to the experience of life, and give out the advantages of using the three kinds of gas: The utility model has the advantages that: (1) the utility model has the advantages of easy ignition, rapid combustion, high thermal efficiency, convenient adjustment of the flame size and convenient use;

Q: Civil gas tank fire, the best way to fight fire?: How to do the gas tank fire in the face of a gas tank at home, should call the police as soon as possible, and timely evacuation of the crowd. If the gas tank heating time is short, the gas tank valve should be closed immediately, and promptly cut off the power supply, if the heating time is longer, do not immediately close the valve or the use of cold water poured out, lest cause explosion. To wait for firefighters arrived in a safe place, after the first uniform cooling of the gas tank, and then fire. The fire gas tank can not be poured to the ground, because the cylinder is burning on the ground, no matter whether the outlet is equipped with a pressure reducing valve, the explosion does not occur. While lying in the cylinder through the gas bottle out of a 250 expansion 300 times, produce high temperature combustion, resulting in cylinder explosion. Accidentally knocked down the cylinder, it should be erected in time.

Q: What are the classification of natural gas: According to the classification of natural gas can be divided into: free gas, dissolved gas, adsorption gas and solid gas;Classification of natural gas by economic value can be divided into: conventional natural gas and unconventional natural gas

Q: What is the use of natural gas: 4, natural gas has the characteristics of safety, the density of natural gas is the air of 1/2, very volatile, not easy deflagration, and non-toxic. Combustion does not produce carbon monoxide and other toxic gases, will not endanger human health, the density is lighter than the air, even if leaked, but also into the air, not easy to form an explosive source. 5, the use of natural gas pipeline transportation facilities: Everfount, change can not breathe, trouble, do not need to store or add on the scene. For industrial and commercial households, natural gas equipment is easier to operate than coal or other fossil fuels

Q: Just for the gas, would like to ask you, how to distinguish between gas cooker and gas stove? There is a connection with the burner tube is what material the safety?: There are two kinds of hard and soft pipes, the hard tube is used to fix the stove. Multipurpose hose for household stove.
