cryogenic thermo-insulation material
1.light weight
2.good uniformity
3.low thermal conductivity

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:Natural gas contains carbon monoxideTV is always said that gas poisoning is how
The carbon dioxide produced is only about 40% of the coal, the sulfur dioxide generated is also very small. After the combustion of natural gas, no waste residue, waste water, compared to coal, oil and other energy sources have the advantages of safe use, high calorific value, clean and so onCO is incomplete combustion produces.OVER.
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:Is the gas in the house toxic?
Mild poisoning, headache, dizziness, tinnitus, nausea, vomiting, palpitations, weakness, etc.. Out of the toxic environment, inhalation of fresh air, a few hours after recovery. In addition to the above symptoms of moderate poisoning, and flushing, cherry red lips, rapid pulse, sweating, irritability, lethargy, gait instability and even coma. General treatment 1 ~ 2 days can be restored, no obvious sequelae. Severe poisoning can quickly coma, lasting several hours to several days. Deep poisoning often complicated by pneumonia, pulmonary edema, myocardial damage, toxic neuropsychiatric disorders.
Q:How to distinguish the use of natural gas and gas
Natural gas is generally composed of methane gas, mainly the production of specialized gas fields, such as coal, gas and oil is a brother, gas is their immediate boss
Q:How to distinguish artificial gas, natural gas, liquefied petroleum gas
2 natural gas pressure 2.0KPa, gas pipeline for most of the country's natural gas is 12T, in some areas there are other gases such as 10T, through the packing box and the nameplate on the type of the gas source and application area can be determined.3 for gas pressure coal 1.0KPa, gas supply is generally gas pipeline, the symbols are 5R, 6R, 7R, R, general in different regions cannot be mixed, the packing box and the nameplate on the type of the gas source and application area can be determined.
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:Oil and natural gas pipeline flange need to do cross wiring?
Electrostatic grounding is not to decide the number of the flange bolts, is based on the measured resistance value to decide, so the requirements of electrostatic grounding: TSG D0001-2009 "pressure pipe safety technology supervision regulation for industrial pipeline" eightieth pipe electrostatic grounding requirements, the resistance value should be measured joint resistance and pipeline system. When the resistance value is more than 20801 or GB/T provisions of the design documents at,
Q:Formation of natural gasConcise, easy to understand,
Natural gas is mainly composed of C elements, is the remains of plants and animals in the earth's crust through complex changes
Q:How did the fire of the gas cooker turn yellow? How to adjust?
Three, the easiest way: record the gas use time. Usually based on the number of members of the family and the frequency of use to determine the average use time of a bottle of normal liquefied petroleum gas as the standard, the time of combustion of liquefied petroleum gas mixed with two dimethyl ether was significantly shortened.
Q:Why is the gas plant often mixed with a small amount of gas in the home gas (mainly carbon monoxide)
City homes can be installed gas alarm to prevent gas poisoningSo the answer is: it is convenient for people to find the gas leakage, close the gas valve, open the doors and windows, and install the gas alarm
