Lesela la Teflon le nang le mocheso o phahameng oa mocheso le sebelisoa joang likarolong tsa mocheso oa mocheso oa li-spacesuits?

I. Material Essence le Positioning in Spacesuits

1. Sebopeho: PTFE-Coated Fiberglass Fabric

Lebaleng la sefofane, sena Teflon lesela la mocheso o phahameng le bitsoa lesela la Beta. E sebelisa lesela la fiberglass e matla haholo e le substrate, e kentsoeng kapa e koahetsoeng ka ntle ho lesela le polytetrafluoroethylene (PTFE, ke hore, Teflon). Sena se kopanya ho feto-fetoha ha lesela ka ho feteletseng-tikoloho inertness ea PTFE.

2. Karolo: Lihlomo tse ka Ho Fetisisa tsa Seaparo sa Thermal Micrometeoroid

Ho ea ka Teflon bahlahisi ba lesela la mocheso o phahameng oa mocheso: Ka har'a tsamaiso ea li-multi-layer insulation system of extravehicular mobility units (EMUs), e sebetsa e le karolo e ka ntle ea Thermal Micrometeoroid Garment (TMG), e shebaneng ka ho toba le vacuum, phapang e feteletseng ea mocheso, le micrometeoroids. E sebetsa e le tšitiso ea pele ea 'mele le ea mocheso bakeng sa likarolo tse ka hare tsa lifilimi tse aluminium.

II. Tikoloho e Feteletseng ea Mocheso le Tšireletso ea Sebopeho

1. Ho mamella Phapang e Feteletseng ea Mocheso le Mahlaseli a Thermal

Lesela la Teflon le nang le mocheso o phahameng oa mocheso le ka mamella mocheso oa nako e telele ho tloha ho -200 ° C ho ea + 260 ° C, le koahela ho fetoha ho matla ho feta 120 ° C ka lehlakoreng le shebaneng le letsatsi le ho theohela ho -160 ° C ka lehlakoreng le nang le moriti. Sebaka sa eona se tšoeu ka tloaelo se bonahatsa mahlaseli a letsatsi, haholo ho fokotsa ho monya mocheso le ho boloka botsitso ba mocheso ka hare.

2. Ho Sireletsa 'Thermal Core' e Fokolang

E sebetsa joalo ka letlalo le thata, le boreleli, le fana ka khanyetso ea mongoako, ho thibela meokho, le ts'ireletso bakeng sa lifilimi tsa polyimide tse tšesaane haholo tse senyehang habonolo. Sena se tiisa botšepehi ba 'multi-layer vacuum insulation' le ho thibela ho hlōleha ha mocheso ho bakoang ke tšenyo e ka ntle ea lera.

III. Thuso ea Motion le Likarolo tsa Tšireletso ea Lik'hemik'hale

1. Thepa e tlase ea Khohlano le Anti-Tangling

Coefficient e tlase haholo ea khohlano ea bokaholimo ba PTFE e fana ka lesela la kantle le nang le litšobotsi tse sa tsitsang, tse boreleli. Ha linohe tsa linaleli li koba matsoho a tsona kapa manonyeletso a 'mele, likarolo ha li sitise ho sisinyeha kapa ho etsa hore ho be le likhohlano ka lebaka la khohlano e phahameng, e netefatsang ho feto-fetoha ha maemo nakong ea ts'ebetso ea extravehicular, joalo ka ha ho boletsoe ke baetsi ba masela a mocheso o phahameng oa Teflon.

2. Lelakabe Retardancy le ho Inertness lik'hemik'hale

Lesela la fiberglass base ka tlhaho le sa che, 'me PTFE ea ho roala ha e chese lelakabe ebile e tsitsitse haholo ka lik'hemik'hale, e khona ho hanela khoholeho e tsoang ho li-oxidizing tse matla tse kang oksijene ea athomo sebakeng. Libakeng tsa khale tse neng li sebelisoa liphaposi tsa oksijene tse hloekileng, ho lieha hona ha lelakabe le ho hanyeha ha kutu li ne li le bohlokoa bakeng sa polokeho ea bo-rasaense.

IV. Likopo tsa Milestone le Phetoho ea Sejoale-joale

1. Lesela la Beta Mehleng ea Apollo - E netefalitsoe ka Ts'ebetso

The Apollo A7L lunar spacesuits e sebelisitsoe haholo lesela la Beta bakeng sa lesela le ka ntle, le mamella ka katleho mocheso oa khoeli ho feta 100 ° C, tšilafalo e bolaeang ea lerōle la khoeli (sebaka se boreleli sa PTFE se hanela ho khomarela lerōle 'me ho bonolo ho se hloekisa), le litlamorao tsa micrometeoroid. Sena se netefalitse ho tšepahala ha eona libakeng tsohle le mocheso o feteletseng.

2. Evolution to Ortho-Fabric in Modern EMUs

Lisutung tsa sepakapaka tse sebelisoang bakeng sa Space Shuttle le International Space Station, bokantle bo fetohile motsoako oa Ortho-lesela. E entsoe ka likhoele tse atolositsoeng tsa PTFE (Gore-Tex), Nomex, le Kevlar. Motheong oa eona, e ntse e itšetlehile ka boemo ba leholimo bo thehiloeng ho Teflon, ho hanyetsa lerole, le mamello e phahameng ea mocheso, ha e ntse e kenyelletsa likhoele tse ling ho matlafatsa matla le ho lieha ha lelakabe. E fetohile lihlomo tsa ho qetela tse ka ntle tse kopanyang tšireletso ea mocheso, tšireletso ea mechine, le thuso ea ho tsamaea.

Haeba u ka rata ho ithuta haholoanyane ka lintlha tse qaqileng, maemo a ts'ebeliso, le likhetho tsa ho itlhophisa bakeng sa lihlahisoa tsa rona tse felletseng - ho kenyeletsoa masela a mocheso o phahameng oa Teflon, tepi ea mocheso o phahameng oa Teflon, mabanta a mocheso o phahameng oa Teflon, mabanta a seamless a sekhomaretsi, lesela le nang le lehlakore le le leng la PTFE, lesela la mocheso o phahameng oa mocheso le fiberglass. masela — ka kopo ikutloe u lokolohile ho ikopanya le rona ka:
