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: How to do out of yellow fire in natural gas stove: 3, nozzle diameter is too large. The nozzle aperture size is different according to the application source differences, the size is too large, often make the gas stove gas causes of emergence and method for removing the yellow fire flow across the rated flow, and the occurrence of yellow fire, when the oxygen shortage, black smoke will happen.Solution: in this case, simply replace the nozzle of the gas source can be.

Q: How to judge the use of gas or gas at home: Artificial gas is the main component of carbon monoxide.The main components of the gas are CO, hydrogen and alkanes, olefins, aromatics, etc.. The gas is toxic because of the CO, and the body of the aromatics to hemoglobin, causing hypoxia, make people remain unconscious or even death, can also make people dizzy, nausea and collapse at low concentrations.Natural gas (natural gas) also known as oil gas, liquefied petroleum gas, petroleum gas. The main component is methane, but also contains a small amount of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc.. Oil and gas only called natural gas; oil and oil gas, the petroleum gas called oil gas or petroleum gas. The chemical composition of natural gas and its physical and chemical properties vary from place to place, no hydrogen sulfide is colorless, odorless, flammable and explosive gases, density of 0.6 ~ 0.8g/cm3, lighter than air. Usually referred to as dry gas containing more than 90% of methane, containing less than 90% of methane is called moisture.

Q: The nature of blast furnace gas: The concept of gas poisoningThe human body in a short period of time to contact a large number of gas, CO and hemoglobin in the blood with the formation of carboxyhemoglobin, causing tissue hypoxia, especially the brain tissue hypoxia, a few seconds will lost activity, this is acute poisoning. The dissociation rate of affinity force of carbon monoxide and hemoglobin and hemoglobin oxygen affinity than 240 times higher.HbCO the ratio of oxygen and hemoglobin is 3600 times slower.

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

Q: How much is the gas in the gas tank?: Gas tank is a movable steel pressure vessel, with the risk of explosion, its wall thickness of only about 2.5 mm (new cylinder factory calibration wall thickness), very book, it always bear the pressure from the internal medium

Q: Where does natural gas come from?: Sources of oil and gasThe sources of oil and natural gas (hereinafter referred to as oil and gas), scientists have two main points: one is considered to be transformed into biological death, and organic production theory. The other is the theory of inorganic generation, which considers the synthesis of petroleum and natural gas. Organic generation theory point of view is based on: almost all fields are found in sedimentary rocks, and sedimentary rocks can see rich biological heritage (such as fossils); through the experiment, organisms in the three major components of protein, carbohydrate and fat can be formed under the condition of similar petroleum hydrocarbons material; heme and chlorophyll and other organic substances found in petroleum, the former is from the animal's blood, the latter from the plant chlorophyll. The oil is put forward after the death of bio transformed opinion is so much more and more fully, so that the organic production theory get the majority of people, now the research methods and contents of oil and gas generation are based on the view of the.

Q: How to use the gas to burn the pot is very black how to solve it: The reason why the gas stove burns the torch pot is black:1, the stove stove head with carbon steel brush clean, need to find.2, is due to the long time no use, there are holes in the spider web block, you can take the stove under the pin, with small things through the spray hole, take out foreign body. The stove is installed after the name of a screwdriver, tapping the stove, is carbon fly, blue flame can be.

Q: What is the difference between the cooker and the gas cooker: I add that the induction cooker uses electricity as an energy source, while the gas stove uses coal as fuel. In contrast, the electromagnetic oven is more environmentally friendly.

Q: What is the standard unit of natural gas?N cubic meters; S cubic meters; and what is the difference between cubic meters?There is no one answer to the.Nm3, is the standard atmosphere, zero perturbation when the volume of gas, which is the international standard; M3 is the standard of China, sometimes written as [M3 (CHN}=], is the standard atmosphere, the gas volume of 20 perturbation);: N is the standard cubic meters of natural gas 1 cubic case, Nm fand's 20 degrees Celsius, 1 cubic meters a under atmospheric pressure.Often said when do cubic meters metering and settlement is generally refers to the N m fand.

Q: What are the uses of natural gas?: Natural gas is stored in underground porous rock, the main component of methane, the proportion of 0.65, lighter than air, with colorless, tasteless, non-toxic characteristics. Natural gas companies are in accordance with the provisions of the government to add odor agent (four thiophene), in order to sniff the user identification.If the concentration of natural gas in the air in the range of 5% to 15%, in case of open flame can occur, the concentration range is the explosion limit of natural gas. The explosion in a short time to produce high pressure, high temperature, its destructive power and risk are great. 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.
