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:Gas stove gas, but can not beat ~ urgent
Three ring, 555, deer, elephant, leopard, train, Nanfu, Changhong, Wang Zhenglong, Mustang battery is good, you can use the time.A lot of customers mistakenly believe that spark is the battery power, in fact, this is a different thing.
Q:Natural gas pipeline is how to connect the seal? How to do not leak
Steel pipe connections are divided into threaded connections and welding. Threaded connection can be sealed with raw tape. Some direct welding welding, and some use flange connection, the use of flange gasket seal (according to different pressure to have different gaskets). In general, the use of low pressure screw connection, so the raw tape is not suitable for high pressure gas seal. In addition, there is a disadvantage of raw tape is removed, so the need to dismantle the site or do not use the tape.
Q:Gas or gas is a general term for gaseous fuels
2, natural gas (T)The main component is CH4, there are a small amount of unsaturated hydrocarbons and CO2, N2, O2 and so onDivided into five categories: 4T, 6T, 10T, 12T, 13T.10T, 12T, 13T rated pressure of 2000Pa, 4T, 6T rated pressure of 1000Pa;Vanward's products are mainly 12T, 13T. currently has basically not 13T production, the so-called natural gas is currently mainly refers to 12T products
Q:Gas stove has been broken fire is how
There are many reasons, 1, the throttle did not adjust well, you can adjust the throttle to the flame burning ideal can be,
Q:1 liquefied petroleum gas and gas?2 what kind of fuel is used in cooking and cooking?3 where can we find the price of all kinds of fuel?
Coal gas is made of solid raw materials, such as coal or coke, which is prepared by distillation or vaporization. Therefore, the toxic gas, easy to form explosive mixture of air, should be used when a high degree of attention.The term "natural gas" refers to the natural gas formed in the formation. But usually called natural gas only refers to a flammable gas rich in hydrocarbon storage in deeper strata, and natural gas and oil symbiosis is often called the oil field. Natural gas from organic substances into the hundreds of millions of years ago. The main component is methane, formed according to different geological conditions in addition, still containing different amounts of ethane, propane, butane, pentane, hexane and other low carbon alkane and carbon dioxide, nitrogen, hydrogen sulfide and other non hydrocarbons; some also contain helium gas. Natural gas is an important energy, widely used as city gas and industrial fuel.
Q:What are the similarities and differences between liquefied petroleum gas stove and gas stove?
Regular manufacturers of natural gas stove marked with T label; liquefied gas stove with Y said, artificial gas stove with R saidFrom the air outlet of the stove can also see, liquefied gas (the highest calorific value of 12000 kcal / m3) so it is the outlet of the fine, ca. 0.1 mm, the middle gas calorific value (8000 kcal / m3) outlet it is 2 mm; artificial gas calorific value (GB: minimum of not less than 3400 kcal / m3) so, it's the largest outlet is about 2.3 mm.
Q:What gas is natural gas?
Natural gas is a kind of multi component mixed gaseous fossil fuel, which is mainly composed of alkanes. It mainly exists in oil fields and natural gas fields. There is no waste residue and waste water after the combustion of natural gas. Compared with coal, oil and other energy sources, it has the advantages of safe use, high calorific value, clean and so on. Natural gas can be divided into two kinds of non associated gas and associated gas
Q:Why is the gas burning black? Is it a gas or a gas cooker?
Oh, my family's gas is still so, wash the pot all those who died. Looking for people to see, basically do a good job, the following list a few questions, you refer to the next.
Q:Natural gas is not new energy? Why?
new energyNew energy (New Energy): also known as unconventional energy. Refers to the various forms of energy outside the traditional energy. Refers to the development or utilization of active research, to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy, etc.. Compared with conventional energy, new energy production scale is small, the scope of application is narrow.
Q:Gas tank valve must not be closed every timeGas stove after each run out, is only the stove switch off, gas tank valve is not closed
Because the stove and the gas tank is connected with a hose, far away, the interface is more flexible hose is also relatively easy to issue
