I. Ubuncwane beMaterial kunye nokuMiswa kwii-Spacesuits
1. Ukuqulunqwa: I-PTFE-Coated Fiberglass Fabric
Kwibala le-aerospace, oku Ilaphu leTeflon elinobushushu obuphezulu libizwa ngokuba lilaphu leBeta. Isebenzisa i-high-high-high-high-high-high-high fiberglass fabric njenge-substrate, efakwe okanye ifakwe kwi-layer yangaphandle kunye ne-polytetrafluoroethylene (PTFE, oko kukuthi, i-Teflon). Oku kudibanisa ukuguquguquka kwelaphu kunye ne-inertness egqithisileyo-bume be-PTFE.
2. Indima: ISikrweqe saNgaphandle seMpatho ye-Thermal Micrometeoroid
Ngokutsho kweTeflon abavelisi belaphu lobushushu obuphezulu: Kwi-multi-layer insulation system ye-extravehicular mobility units (EMUs), isebenza njengomaleko ongaphandle we-Thermal Micrometeoroid Garment (TMG), ejongene ngqo ne-vacuum, ukuhluka kobushushu obugqithisileyo, kunye ne-micrometeoroids. Isebenza njengesithintelo sokuqala somzimba kunye nesobushushu kwishumi elinambini okanye langaphakathi leefilim ezilunyunyisiweyo.
II. Imekobume yobushushu obugqithisileyo kunye nokuKhuselwa koLwakhiwo
1. Ukumelana noMahluko oBubushushu obugqithisileyo kunye neMitha yeThermal
Ilaphu leTeflon elinobushushu obuphezulu linokumelana namaqondo obushushu ukusuka ku-200 ° C ukuya +260 ° C, ligqume ukuguquguquka okuqatha okungaphezulu kwe-120 ° C kwicala elijonge ilanga lendawo kunye nezantsi ukuya kuthi ga kwi -160 ° C kwicala elinomthunzi. Indawo yayo emhlophe ngokuqhelekileyo ibonisa ngokufanelekileyo ukusasazeka kwemitha yelanga, ukunciphisa kakhulu ukufunxa ubushushu kunye nokugcina uzinzo lwangaphakathi lobushushu.
2. Ukukhusela i-'Thermal Core' ebuthathaka
Isebenza njengolusu oluqinileyo, olugudileyo, olunikezela ukuxhathisa, ukuxhathisa ukukrazuka, kunye nokhuseleko lokunxiba kwisiseko esincinci kakhulu kwaye sonakaliswe lula iifilimu ze-aluminum ze polyimide. Oku kuqinisekisa ukunyaniseka kwe-multi-layer vacuum insulation kunye nokuthintela ukungaphumeleli kwe-thermal okubangelwa ngumonakalo wangaphandle.
III. Uncedo lweMotion kunye neMicimbi yoKhuseleko lweMichiza
1. IiPropati eziNgxaki eziPhantsi kunye neePropati ezichasayo ukuHlanganisa
I-coefficient ephantsi kakhulu yokukhuhlana komphezulu we-PTFE inika ilaphu langaphandle elineempawu ezingezizo intonga, ezigudileyo. Xa oosomajukujuku begoba iingalo zabo okanye amalungu e-torso, iileya azithinteli ukunyakaza okanye ukudala i-tangles ngenxa yokukhuhlana okuphezulu, ukuqinisekisa ukuguquguquka ngexesha lemisebenzi ye-extravehicular, njengoko kuphawulwe ngabavelisi be-Teflon bobushushu obuphezulu.
2. Ukungakhathali kweFlame kunye nokuNganyanzeli kweMichiza
Ilaphu lesiseko se-fiberglass ngokwendalo alitshi, kwaye i-PTFE yokwambathisa ayinamlilo kwaye izinzile ngokwekhemikhali, ekwaziyo ukuxhathisa ukhukuliseko oluvela kwi-oxidizing agents ezinamandla njengeoksijini yeathom esithubeni. Kwiindawo ezisetyenziswa ngokwembali zekhabhinethi ye-oksijini ecocekileyo, oku kubambezeleka kwedangatye kunye nokumelana nokubola kwakubalulekile kukhuseleko lukasomajukujuku.
IV. IMilestone Applications kunye ne-Modern Evolution
1. Ilaphu le-Beta kwiXesha le-Apollo - liProven in Action
I-Apollo A7L i-spacesuits yenyanga esetyenziswa kakhulu kwilaphu yeBeta yomaleko ongaphandle, imelana ngempumelelo nomphezulu wenyanga ngaphezulu kwe-100 ° C ubushushu, ukungcoliseka kothuli olubulalayo lwenyanga (umphezulu we-PTFE ogudileyo umelana nokuncamathelisa uthuli kwaye kulula ukuyicoca), kunye neempembelelo ze-micrometeoroid. Oku kuqinisekise ukuthembeka kwayo kuzo zonke iindawo kunye nobushushu obugqithisileyo.
2. I-Evolution ukuya kwi-Ortho-Fabric kwii-EMUs zanamhlanje
Kwiisuti zasemajukujukwini ezisetyenziselwa iSpace Shuttle kunye neSikhululo saMajukujuku saMazwe ngaMazwe, umaleko wangaphandle uguqukele ekubeni yi-Ortho-fabric blend. Ilukwe kwiifiber ezandisiweyo ze-PTFE (Gore-Tex), iNomex, kunye neKevlar. Embindini wayo, isathembela kwiTeflon-based weatherability, ukumelana nothuli, kunye nokunyamezelana kobushushu obuphezulu, ngelixa idibanisa ezinye iifibers zokwandisa amandla kunye nokubuyiswa komlilo. Iye yaba sesona sikrweqe sangaphandle esidibanisa ukukhuselwa kobushushu, ukukhuselwa komatshini, kunye noncedo lwentshukumo.
