Cryogenic Thermal Insulation Paper

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 safely use the gas?: First, the use of gas should pay attention to what?The use of gas must pay attention to whether there is a smell, to ensure no leakage and then use the fire, and pay attention to ventilation should be good.

Q: What are the characteristics of artificial gas?: Artificial gas is produced in industrial production, mainly with steam and hot carbon reaction, the formation of hydrogen and carbon monoxide, and then extract the hydrogen for other purposes

Q: How much is a natural gas in 2014?: Is the answer as long as the answer to a word, if it is, it can only use 'expensive' to describe the word.

Q: What is the stripping gas in natural gas desulfurization process?: The content of carbon dioxide is too high, which puts forward higher requirements for the desulfurization process, desulfurization agent and desulfurization equipment. The desulfurization Changchun Dongshi Science & Trade Industrial Co. Ltd. east lion desulfurization technology collaboration network technology as a platform for domestic wet oxidation desulfurization in recent years focused on biogas industry, from desulfurization to professional desulfurization desulfurization equipment research and improvement has done a lot of work.

Q: Can you put the gas tank outside in the summer?: Only the gas leaking into the air exploded in space. The above is about the chemical explosion, there is a physical explosion, chemical explosion, physical explosion occurred in the gas tank, gas tank fire, when under high temperature conditions, the gas inside the tank can be increased due to intermolecular repulsion, is also increasing, there is a need to expand the space demand, but by the tank the sealing function can not meet the demand of the expanded volume

Q: Could you tell me the difference between liquefied petroleum gas and natural gas: Are oil and "similar"; the main difference is: 1, the proportion of different liquefied petroleum gas is heavier than air, natural gas is lighter than air; 2, mixing it with air to gas deflagration of the mixing ratio is different; 3, the calorific value of produced when they are burned with different calorific value of liquefied gas quality the calorific value of natural gas is 22000 kcal, 8500 kcal is. 4, their composition is different, liquefied petroleum gas is mainly composed of propane or butane, natural gas is methane. It is possible to use the same stove.

Q: When you find the home gas leak, you will immediately take the approach is ()A. open exhaust fanB. close the gas valve, open the doors and windowsC. immediately hit 119 alarmD. water the house so that the gas is absorbed by water: B, a gas leak, the ventilation window, make indoor air convection, the concentration can reduce the temperature of the gas and reducing the combustible gas, the mixed gas is not up to the fire and explosion limit, so right.

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 are the uses of natural gas?: Natural gas is mainly used for the following purposes:1, natural gas power generation, can alleviate the energy shortage, reduce the proportion of coal-fired power generation, the effective way to reduce environmental pollution, and from the economic perspective, natural gas power generation unit installed capacity required less investment, shorter construction period, lower electricity price, with strong competitiveness.2, natural gas chemical industry, natural gas is the best raw material for the production of nitrogen fertilizer, with less investment, low cost, less pollution, etc.. Natural gas accounts for the proportion of raw materials for nitrogen fertilizer production, with an average of around 80% in the world.3, the city gas industry, especially the living fuel. With the improvement of people's living standard and the enhancement of environmental protection consciousness, the demand for natural gas in most cities has increased obviously. The economic benefits of natural gas as civil fuel are also greater than that of industrial fuel.4, compressed natural gas vehicles, natural gas instead of oil, with low price, less pollution, safety and other advantages.At present, people's environmental awareness, the world demand for clean energy is running high, governments have to convey this trend through legislative process, natural gas has been regarded as one of the most clean energy, coupled with the 1990 Middle East of the Persian Gulf crisis, the United States and major oil consuming countries to deepen the development of alternative energy determination, therefore, in haven't found the real alternative energy, natural gas demand will naturally increase.

Q: Liquefied gas and coal gas _?: Both of them are gas fuels, but they are not the same thing.Coal gas is made from coal. The main components of gas are carbon monoxide, hydrogen and methane. After the gas was born in the gas plant, it was stored in a large gas tank, and then ran down the gas pipe to your home. Therefore, only in the place where there is a gas plant, the laying of the gas pipeline in place, it is possible to use gas.
