waterproof and fireproof insulation for lng cryogenic storage

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:Is it okay to turn off the gas stove after using the gas?: (4) hose not close to stove. On the desktop stove, the hose is not below or across the disc, should pull around, if the hose from the height of next, don't let the flames of the fire to. For embedded cooker, hose not close to the stove. Hose should be in the kitchen surface natural droop, to maintain the distance of 10 cm or more, the length should not be more than 2 meters, so as not to burn off the fire.(5) after the hose is installed, it can be used to detect the leakage of soap and water. Open the gas switch to see if there is a continuous bubble, if so, it shows that leakage, unsafe.

Q:What is the density of natural gas: 1 density and relative densityUnder normal temperature and atmospheric pressure, the density of methane is 0.7174kg/m3, the relative density is 0.5548.The density of natural gas is generally 0.75 kg/m3 ~ 0.8kg/m3, the relative density is generally from 0.58 to 0.62.2 ignition temperatureThe ignition temperature of methane is 540.3 combustion temperatureThe theoretical combustion temperature of methane is 1970.The theoretical combustion temperature of natural gas can reach 2030.

Q:Is the gas rising or falling when the gas is leaking?: The main component of natural gas is methane, its density is about 0.72 kilograms per cubic meter

Q:In addition to the wind, but also what conditions?When you wake up, inhaling gas will be uncomfortable?: 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:

Q:How to buy range hood and gas stove: The quality of x0d motor hood of the most important part is the motor drives the wind wheel, the design requirements of the quality of domestic motor can completely reach the hood, at the time of purchase, do not blindly imported motor, resulting in higher purchase price. The bearing is an important component of the motor, when buying the choose motor double ball bearing, long service life. It's low noise. In addition to select metal spray wind wheel configuration, it is durable, stable performance, conducive to the separation of soot. The time of purchase, to repeatedly pressing the motor start switch, compare the motor start and shut down the operation of sound, noise as possible.x0d

Q:What is water gas?What is the principle?: Simplification of chemical formula: C+O2= =CO2 (lit on both sides because the reactants and products are water, at the same time. But to also want to follow the principle of objectivity, the temperature of the reaction conditions the removal of carbon and oxygen to form carbon dioxide).In fact, water gas is so simple...... But this is not about me to follow the principle of objectivity, the standard is in turn.

Q:Natural gas pipeline to what kind of joints to connect the wall boiler and gas stove?: 1, one end of the self closing valve for the connection of stainless steel bellows, and to connect the gas stove (bellows dedicated).Generally use the size of 16mm (1/2) pipeline, joints, valves.

Q:Compressed natural gas in the end of this cargo is a few categories: Physical and chemical properties: colorless odorless liquidMelting point (-182): slightly soluble in water; soluble in ethanol, ethyl etherBoiling point (c): -160~-164 relative density (water =1): 0.42 (-164 C)Saturated vapor pressure (Kpa): 53.32 (-168.8 DEG C) relative density (air =1): 0.45Critical temperature (c): -82 combustion value (KJ.mol-1): 889.5Critical pressure (Mpa): 4.59 minimum ignition energy (fro): 0.28

Q:0.3T gas steam boiler about one hour to burn a lot of natural gas: 1 tons of boiler =60 kcal. 0.3T boiler =18 kcal,The calorific value of natural gas is about 8600 kcal, 0.3T gas steam boiler theory about an hour by 21 party gas, taking into account the actual utilization efficiency of boilers and boiler, steam boiler 0.3T gas per hour the actual gas should stand in 15-25.

Q:How do I open the valve, or no gas ah?: The first to open the gas tank, the right hand is the direction of their own twist, and then turn on the gas stove can be it, very simple
