High-performance airgel insulation cover material saving features and applications
High performance airgel insulation shield material saving gas gelling material is in the range of temperatures to satisfy the flexible or rigid -200 ℃ ~ 800 ℃ high performance thermal insulation material. The pore size of the material in the nanometer scale , which can effectively suppress air convection heat and thermal conductivity of solid phase , is a class of high-performance thermal insulation materials.
Aerogel materials Description:
Nanoporous airgel ( referred aerogels ) a dispersing medium for the material gas is a gel material that is accumulated by the polymer molecule to the colloidal particles or nano- porous solid material having a network structure composed of the the pore size of the material in the nanometer level . 80 to 99.8 % of its high void ratio , the pore size is typically 1-100 nm, and the density can be as low as 3 kg/m3, a low coefficient of thermal conductivity at room temperature 0.012 W / (m • K). It is because of these characteristics make airgel material has a very broad application potential in the aerospace , shipbuilding, construction , new energy , petrochemicals , clothing , catalysts , electrochemical and other aspects .
Aerogel Aerogel is divided according to ingredients can be divided silica airgel , airgel zirconia , alumina airgel and carbon airgel and so on. Which silica airgel temperature up to 600 ℃, zirconium oxide airgel temperature up to 1300 ℃, carbon aerogels temperatures up to 2000 ℃.
Aerogel insulation cover material applications:
( A ) airgel insulation cover in the chemical aspects of petroleum
It is reported that one of the key operating personnel needs in the subsea oil and gas field exploration , transmission capacity is unprocessed carbon hydrogen compounds , they are often in a state of high temperature and pressure , and the transmission distance along the sea floor is also getting longer . Without adequate insulation, the cooling occurs Hydrocarbons hydrate or wax and eventually plug the flow line , the operator generates a huge cost , superior insulation performance airgel can be a good solution to this problem .
(B ) airgel insulation cover in the ship above
With the development of ocean transportation, offshore oil field , with supporting offshore drilling platforms, oil tankers, liquefied natural gas (LNG) vessels , liquefied petroleum gas (LPG) vessels developing rapidly. These special vessels for thermal insulation and fire separation put forward higher requirements, has become the new platform application airgel material .
(C ) airgel insulation cover applications in the construction of
Aerogel excellent insulation properties so that he can have a very strong potential in terms of building insulation , aerogels relative to polystyrene foam insulation currently used not only better , but also non-flammable , can effectively prevent the occurrence of fire . Anti-aging properties of aerogels is also very good thermal insulation body can guarantee 30 years without aging. Aerogel is currently relatively high cost , such as the optimization process more future cost reductions , will a large number of applications in terms of building insulation . The same time as translucent airgel , it can be used to make the transparent roof.
(D ) airgel insulation kits in aerospace aviation applications
Currently, the airgel has been widely used in the aerospace needs insulation in place . Which one is used in aerospace applications heat the battery , as the use of airgel insulation layer material perfect solution for aerospace thermal battery performance requirements , insulation gas condensate below shows some hot battery plastic materials.
(E ) sets airgel applications in other areas
Aerogel insulation kits excellent thermal insulation properties makes him in electrochemistry , clothing, new energy, catalysts , also has a very strong application potential. Since aerogels are nanoscale pores , large specific surface area which makes him a large adsorption capacity , can be used to make the supported catalyst ; due to adsorption , while low density , it can also be used hydrogen storage ; him good insulation can be used to make clothing , only a thin layer of insulation can achieve good results.
As a thermal insulation material that can be used for thermal protection supersonic aircraft , armored vehicles, ships and other high-power engine insulation, industrial insulation and efficient heat batteries, green intelligent buildings and other high-temperature furnace insulation ; as fire separation materials available on large ships , high-rise building fire doors, fire bulkhead manufacturing ; available for special clothing ( winter clothes, fire service, bulletproof vests ) manufacturing, insulation materials, catalyst carrier.
