1. Mapangidwe: PTFE-Yokutidwa ndi Fiberglass Fabric
Mu gawo lazamlengalenga, izi Nsalu ya Teflon yotentha kwambiri imatchedwa nsalu ya Beta. Amagwiritsa ntchito nsalu ya fiberglass yamphamvu kwambiri ngati gawo lapansi, lomwe limayikidwa kapena yokutidwa pakunja kwa polytetrafluoroethylene (PTFE, mwachitsanzo, Teflon). Izi zikuphatikiza kusinthasintha kwa nsalu ndi kusakhazikika kwachilengedwe kwa PTFE.
2. Udindo: Zida Zakunja Zakunja za Chovala cha Thermal Micrometeoroid
Malinga ndi opanga nsalu za Teflon zotentha kwambiri: Mu makina opangira ma multilayer insulation system a extravehicular mobility units (EMUs), amakhala ngati wosanjikiza wakunja wa Thermal Micrometeoroid Garment (TMG), moyang'anizana ndi vacuum, kusiyana kwakukulu kwa kutentha, ndi micrometeoroids. Imakhala ngati chotchinga choyamba chakuthupi komanso chotenthetsera pamagulu khumi ndi awiri kapena angapo amkati amafilimu opangidwa ndi aluminiyamu.
II. Malo Otentha Kwambiri ndi Chitetezo Chachipangidwe
1. Kupirira Kutentha Kwambiri Kusiyanasiyana ndi Kutentha kwa Matenthedwe
Nsalu ya Teflon yotentha kwambiri imatha kupirira kutentha kwa nthawi yayitali kuyambira -200 ° C mpaka +260 ° C, kuphimba kusinthasintha koopsa kwa 120 ° C kumbali yoyang'ana dzuwa ndi kutsika mpaka -160 ° C kumbali yamthunzi. Kuyera kwake komwe kumakhala koyera kumawonetsa kuwala kwa dzuwa, kumachepetsa kwambiri kuyamwa kwa kutentha ndikusunga kutentha kwamkati.
2. Kuteteza 'Thermal Core' yofooka
Imakhala ngati khungu lolimba, losalala, lomwe limapereka kukana kukanda, kukana kung'ambika, komanso chitetezo chovala pamakanema owonda kwambiri komanso owonongeka mosavuta a aluminium polyimide. Izi zimatsimikizira kukhulupirika kwa ma multi-layer vacuum insulation ndikuletsa kulephera kwamafuta komwe kumachitika chifukwa cha kuwonongeka kwakunja.
III. Thandizo la Motion ndi Chemical Safety Features
1. Katundu Wotsika Kwambiri ndi Anti-Tangling Properties
The kwambiri otsika coefficient wa mikangano padziko PTFE endows nsalu akunja ndi sanali ndodo, yosalala makhalidwe. Akatswiri a zakuthambo akamapindika manja awo kapena ziwalo za torso, zigawozo sizilepheretsa kuyenda kapena kupanga zomangira chifukwa cha kukangana kwakukulu, kuonetsetsa kuti kusinthasintha pazochitika za extravehicular, monga taonera ndi opanga nsalu za Teflon zotentha kwambiri.
2. Flame Retardancy ndi Chemical Inertness
Nsalu za fiberglass ndizosayaka, ndipo zokutira za PTFE sizimawotcha komanso zimakhazikika pamankhwala, zomwe zimatha kukana kukokoloka kwa zinthu zamphamvu zotulutsa okosijeni monga mpweya wa atomiki mumlengalenga. M'malo omwe kale ankagwiritsidwa ntchito m'kanyumba kanyumba kokhala ndi okosijeni, kuchedwa kwa lawi komanso kukana dzimbiri kunali kofunika kwambiri pachitetezo cha astronaut.
IV. Milestone Applications ndi Modern Evolution
1. Beta Nsalu mu Nthawi ya Apollo - Yatsimikiziridwa mu Ntchito
Zovala zam'mlengalenga za Apollo A7L zomwe zimagwiritsidwa ntchito kwambiri ndi nsalu za Beta zakunja, kupirira bwino kutentha kwa mwezi kupitirira 100 ° C, kuipitsidwa ndi fumbi la mwezi (malo osalala a PTFE amakana kumatira kwa fumbi ndipo ndikosavuta kuyeretsa), komanso kukhudzidwa kwa micrometeoroid. Izi zinatsimikizira kudalirika kwake kumadera onse ndi kutentha kwambiri.
2. Evolution to Ortho-Fabric in Modern EMUs
Pazovala zakuthambo zomwe zimagwiritsidwa ntchito pa Space Shuttle ndi International Space Station, wosanjikiza wakunja wasintha kukhala wosakanizika wa nsalu za Ortho. Amapangidwa kuchokera ku ulusi wowonjezera wa PTFE (Gore-Tex), Nomex, ndi Kevlar. Pachimake chake, imadalirabe Teflon-based weatherability, fumbi kukana, ndi kulekerera kutentha kwakukulu, ndikuphatikizanso ulusi wina kuti uwonjezere mphamvu ndi kuchedwa kwamoto. Chakhala chida champhamvu kwambiri chakunja chomwe chimaphatikiza chitetezo chamafuta, chitetezo chamakina, ndi chithandizo choyenda.
