flame-retardant cryogenic insulation paper

Flame-retardant cryogenic insulation paper(compatibility with oxygen) :

The flame-retardant cryogenic insulation paper is made of super-thin glass wool, which is produced in all -electrical kiln with blaze technology, by a peculiar manufactory process. The insulation paper is often composited with aluminum foil as a thermal insulation material for using in the vacuum jackets of storage and transportation vessels for cryogenic liquids(Liquid Hydrogen liquid oxygen, LNG, liquid Helium, liquid Nitrogen and liquid Argon).Its advantage are flame-retardant  at open fire and with the best thermal insulation characteristic(lower thermal conductivity, higher contact thermal resistance),low outgassing rate, light weight, high uniformity and wide range of the application temperature:-269°C-800°C

Q:How to distinguish the use of natural gas and gas
It seems to be natural gas. Instead of gas
Q:The valve and the stove domestic natural gas tube to connect with what
Look at the label and the nameplate, there are available gas typesPipe with plastic material on the gas pipe on the line
Q:Which position is the gas cooker in
In the camp,. Your home headed woman, man is a bit poor, handle the east gate, arranged a 120 pound big stone at the door, with a red pen to write on the "Taishan this" can relieve
Q:Role of gas tank pressure relief valve
Gas tank pressure relief valve is generally not adjusted.Gas tank pressure reducing valve is the role of liquefied gases in the tank to reduce pressure into gas, through the pipeline, leading to gas stoves burning.
Q:How to open the automatic valve of natural gas alarm
Open the valve manually after normal use, please check whether there is a preliminary home gas leak, method of ear whether there is air sound, smell smell, apply soapy water after to see whether there is a bubble, avoid fire leak testing, if found to have leaked into the household immediately closed the valve, the ventilation window, contact the Gas Co to help.
Q:What are the uses of natural gas?
The remains of the natural gas system, which have been deposited underground for a long time, are converted into gas hydrocarbons by the gradual transformation and pyrolysis.
Q:What is the amount of heat contained in a natural gas
So the calorific value per cubic meter is 33494.4 - 35587.8KJ.And 1 degrees =1kW*h=3.6*10^6J=3.6*10^3KJ.
Q:The nature of blast furnace gas
Two, physical and chemical properties and hazardous characteristics of converter gas:The physicochemical properties of 1, converter gas mainly depends on the gas composition, gas properties of different components of different, inflammable and explosive, easy poisoning is one of the three major characteristics of gas poisoning, fire and explosion. Often referred to as the three gas accidents.2, converter gas is a flammable and explosive gas, carbon monoxide explosion limit is 12.5 74.2%. mixed with air can form explosive mixtures, in case of fire, electric spark, high temperature above 650 degrees and glowing metal objects will cause combustion and explosion.3, converter gas is a highly toxic gas, the human body in a short period of time in contact with a large number of gas, will cause tissue hypoxia, so a long time in the gas area, carbon monoxide concentration should not exceed 30mg/m3 (24ppm)
Q:Home gas smell, but check the gas altar and no problem, how
With a bowl of water diluted detergent you advice, and then open the interface of gas cutting and brush cleaner wash detergent water from the gas bottle and gas pipe down the trachea has been swept to the gas stove at the interface (note that the bottom of the pipe should stick to detergent water) and then carefully observe the look of that place small bubbles continue to emerge, there is a leak. Note that when you check the air circulation, the room was found to have a gas smell, do not use the open and close appliances, should try to let the natural gas dispersed dilute
Q:How much gas will you die?
But the gas in anti HIV usually occurs in sleep, ventilation in the kitchen, will not cause poisoning.How to do gas poisoningHow do the family of gas poisoning gas poisoning mainly refers to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas, natural gas poisoning, the former is more common in winter heating coal stove, doors and windows closed, smoke is poor, which is common to liquefied gas pipeline leak leak or stove. Gas poisoning patients initially feel headache, dizziness, nausea, vomiting, weak and feeble, when he realized the poisoning, often struggle out of bed to open the door, open the window, but only a few people can open the door, most of the patients rapidly pumping spasm, coma, cheeks, chest skin and lips of cherry red colour, if the treatment is not timely. But soon died of respiratory depression. According to the concentration of carbon monoxide in the air and the time of poisoning, gas poisoning is usually divided into three types:
