aluminosilicate refractory fiber paper for lng cryogenic storage

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:What are the natural gas charges paid by the unit,
Units to pay the cost of natural gas, if it is an administrative unit with office included in the expenditure"
Q:1 inch water gas pipe diameter
Water gas pipe? Galvanized pipe or pipe. 1 inches is the British law, such as the outer diameter of a variety of 4. The British 1 inch is divided into 8 points, so the is 1/2 inches, 6 minutes is 3/4 inches, the 8 point is the size of 1 inches4 in charge of 12 - diameter 12.5mm often say DN156 in charge of 34 --- --- diameter 19mm DN201 inch tube 1 "--- diameter 25.4mm DN25
Q:How many kinds of natural gasWhat are their uses
The distribution of natural gas in petroleum geology, usually referred to as oil and gas fields. It is composed mainly of hydrocarbons and contains non hydrocarbon gases. The broad sense of natural gas refers to all the natural gas generated in the earth's crust, including oil field gas, gas field gas, mud volcanic gas, coal support and bio gas generation. According to the phase state of natural gas in the underground, it can be divided into free, dissolved, adsorbed and solid state. Only the free form of natural gas can be formed by accumulation of natural gas.
Q:What about the gas tank on fire?
If the angle valve is damaged, can not cut off the gas source, then do not blindly extinguish the fire, you can quickly move the cylinder to an outdoor safe place, let it burn, and constantly cool down the water to prevent the heating cylinder explosion. At this point, must not be able to fire the gas tank on the ground. Because the cylinder on the ground combustion, regardless of whether or not the installation of pressure relief valve, generally does not explode. While lying in the cylinder through the gas bottle outflow, the rapid expansion of 250 to 300 times, to produce high temperature combustion, resulting in cylinder explosion. Accidentally knocked down the cylinder, it should be erected in time.
Q:How to safely use the gas tank, should pay attention to what matters
5, ignition method. The correct ignition method is "fire and gas", that is, first unscrew the valve and the valve on the switch, and then open the switch on the stove ignition.6, the pressure reducing valve to check the sealing rubber ring, do not change, defect, install the valve hand wheel to the valve port, to counter clockwise rotation.Connecting parts 7, rubber tube, stove switches, pressure relief valve and the valve hand wheel to the bottle is easy to leak site, please check the leak brushing with soapy water to check the site, do not use fire leak.
Q:How many cubic meters of natural gas is equivalent to a tank of liquefied petroleum gas?
The reporter then news in Guildford road building 22 floor, Mr. Du home were tested, Mr. Du home use liquefied petroleum gas, or the same pot and 1000CC from ignition to boiling water, consumption of 0.010 cubic meters of liquefied petroleum gas. Roughly compared to 1000CC of water to be completely burned, the consumption of natural gas and liquefied petroleum gas volume is nearly 2.8 times.Little time differenceReporters also found in the experiment, when the old lady's house to boil a pot of water needs 4 minutes and 48 seconds, while Mr. Geng old home spent a total of 4 minutes and 55 seconds, Mr. Du home after 4 minutes to boil the water. The time required from the three different families with burning a pot of water, the difference is not great.
Q:What are the symptoms of inhaling gas
(2) medium: poisoning time is slightly longer, the blood of carbon oxygen hemoglobin accounts for 30% ~ 40%, in the light of symptoms, can appear collapse or coma. The skin and mucous membranes are characteristic of a cherry red. Such as rescue in a timely manner, can quickly awake, within a few days to fully recover, generally no symptoms.(3): heavy found too late, too much gas inhalation, or inhalation of high concentrations of carbon monoxide in a short period of time, the concentration of blood carboxyhemoglobin often in more than 50% patients showed deep coma, various reflex, incontinence, cold limbs, blood pressure drops, shortness of breath, will soon die. In general, the longer the coma, the more serious the prognosis, often left dementia, memory and comprehension, limb paralysis and other sequelae.
Q:The gas in the gas tank is used up. What's wrong with the water?
Gas Co in the filling, impurity bottle and bottle wall and with the oxide is cleared up, and the weight of material is relatively heavy, but no weight, from a certain extent against you as a consumer of power.
Q:Natural gas can not be renewable
Renewable energy refers to renewable energy, including biomass energy, solar energy, light energy, biogas, etc.. Biomass energy is mainly refers to the sweet sorghum, etc., refers to a variety of inexhaustible energy, strictly speaking, is not consumed during the human history of energy. Renewable energy does not contain current limited energy sources, such as fossil fuels and nuclear energy.
Q:How to do mild coal
How to do a little gas poisoning(1) open the doors and windows immediately and move the patient in a well ventilated place with fresh air. Find the cause of the gas leakage, eliminate hidden dangers.(2) release button, keeping respiratory tract unobstructed, clear respiratory secretions, such as respiratory arrest, should immediately do mouth to mouth resuscitation, and make cardiac massage in vitro.(3) immediate acupuncture treatment, acupuncture, lack of people, taking less, ten Xuan, Hegu, Zusanli springs, sun, etc.. Light, moderate poisoning, acupuncture can be gradually regained consciousness.(4) immediately to the oxygen, the conditions should be immediately transferred to the hospital hyperbaric oxygen chamber for hyperbaric oxygen therapy, especially suitable for medium and heavy gas poisoning patients, not only can make the patient awake, still can make to reduce sequelae.
