Aluminum Foil Laminated Cryogenic 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:What is a cryogenic fast line
Cryogenic metal industry technology refers to the black metals, nonferrous metals, polymers, carbide and so on at cryogenic temperature heat preservation material, make it happen at room temperature and never happened in the process of heat treatment of the internal structure change, lead to the change of macro performance. For example: die steel, high speed steel, cemented carbide strength and toughness were improved after cryogenic treatment, and break through the traditional hardness and toughness of contradictory phenomenon, show the comprehensive performance improved. Domestic contribution to cryogenic technology research institute of Chinese academy of sciences, is the biggest should from the several aspects, such as equipment, mechanism, process research and extension of cryogenic technology, cryogenic in cutting tools, moulds, valves, and other industries extensively with the Chinese academy of sciences of physics and chemistry ? all the inseparable relations
Q:Cryogenic treatment to improve what performance?
Cryogenic treatment (cryogenic treatment) refers to the materials needed at -190 DEG C to -230 DEG C under treatment. Suitable for all metal or nonmetal material, such as alloy, carbide, plastic (nylon and Tie Fulong), aluminum, ceramics etc..
Q:How many changes in the properties of the cryogenic metal?
The name of the processing content specification / processing content of the original service life (sub / piece) after the service life (times / pieces)1 milling cutter milling keyway 7.5-2NT 40034352 step drilling hole Phi: 1.2, 23, 1331004163 milling cutter milling air hole Phi 11.5, 32-2NT
Q:I would like to ask how the process of cryogenic treatment
Biology: fast cooling, can prevent the crystallization of cells in the water, does not destroy the cell organization. In the preservation of sperm, organ preservation, food preservation, preservation of certain life and so onMedical treatment: cryotherapy, treatment of certain skin diseasesSpace: the space environment simulation, satellite ground test station, using liquid helium, create -200 degrees of low temperature.Noise: high sensitivity radar telescope, using liquid helium cooling, receiving device, noise reductionVacuum: the use of cold well technology can get high vacuum
Q:What is the meaning of vacuum cooling in heat treatment
In order to eliminate residual austenite after heat treatment, after quenching or tempering
Q:What is the meaning of deep frozen
So people use frozen ways to preserve food. Generally in a very short period of time, such as half an hour, so that the need to freeze the food quickly reach the specified ultra-low temperature, such as -30 ~-40 C.
Q:Can the cryogenic phase control the cooling rate?
2, the compressor refrigeration principle: the use of the suction pipe of refrigerant gas inhalation of low temperature and low pressure, through the operation of the motor drives the piston to compress it after high temperature and high pressure refrigerant gas discharge pipe to the exhaust, to provide power for the refrigeration cycle, so as to realize the compression, condensation, expansion and evaporation (endothermic) refrigeration cycle. The refrigerant of the compressor can be repeatedly used for a plurality of times, the consumption is relatively small, the power consumption in the refrigeration process is more, the cooling rate is relatively small, and the refrigeration temperature range is 0-80 DEG C. The above mentioned two kinds of refrigeration in the process of industrial production of cryogenic box, the use of liquid nitrogen refrigeration will be more. Liquid nitrogen refrigeration can be used in the temperature range from 0 DEG C to -196 DEG C. []
Q:What is the meaning of cryogenic technology in the mechanical process, what is the specific practice?
Treatment of -130 DEG C is said to be a new and strong treatment process of cryogenic treatment to improve the wear resistance and toughness of materials and to improve the overall service life
Q:Ultra low pressure casting mold useful, how to arrange the process? Thank you
While casting field production high temperature is about 660 degrees, some die casting production Aluminum Alloy temperature of 740 degrees, copper alloy die-casting production temperature even up to about one thousand degrees, the temperature and the ambient temperature, the temperature fluctuation is bigger, hot and cold alternating stress caused by the greater! That is, the stress produced in the production process is very large, even if the cryogenic treatment, the stability of the role of the size of the casting mold and plastic mold is not obvious! As for how you choose, you might as well try!
