I. Nkoka wa swilo na ku vekiwa eka swisuti swa le xibakabakeni
1. Xivumbeko: Lapi ra Fiberglass leri funengetiweke hi PTFE
Eka nsimu ya swa swihahampfhuka, leswi Lapi ra teflon leri hisaka swinene ri vuriwa lapi ra Beta. Yitirhisa lapi ra fiberglass ra matimba swinene tani hi substrate, leri cheriweke kumbe ku cheriwa eka leyara yale handle hi polytetrafluoroethylene (PTFE, ie, Teflon). Leswi swihlanganisa ku olova ka lapi na extreme-environment inertness ya PTFE.
2. Ntirho: Xisirhelelo xa le handle swinene xa Xiambalo xa Thermal Micrometeoroid
Hikuya hi vaendli va malapi ya mahiselo yale henhla ya Teflon: Eka sisiteme ya multi-layer insulation ya ti extravehicular mobility units (EMUs), yitirha tani hi leyara yale handle swinene ya Thermal Micrometeoroid Garment (TMG), yi langutane hiku kongoma na vacuum, ku hambana ka mahiselo yo tlula mpimo, na ti micrometeoroids. Yitirha tani hi xisirhelelo xosungula xa physical na thermal eka khume-mbirhi kumbe kutlula ti layers tale ndzeni ta ti films letinga aluminized.
II. Ntivo-mbango wa ku Hisisa lokukulu na Nsirhelelo wa Xivumbeko
1. Ku Tiyisela Ku Hambana Ka Mahiselo yo Tlula Mpimo na Radiation yo Hisisa
Teflon high-temperature fabric yinga tiyisela nkarhi woleha mahiselo kusuka eka -200°C kuya eka +260°C, yi funengeta ku cinca cinca lokukulu kutlula 120°C eka tlhelo leri langutaneke na dyambu ra ndzhawu naku ya ehansi kuya eka -160°C eka tlhelo leringana ndzhuti. Vuandlalo bya yona lebyi hi ntolovelo byi basa byi kombisa kahle miseve ya dyambu, leswi hungutaka swinene ku amukeriwa ka kuhisa xikan’we naku hlayisa kutshamiseka ka mahiselo yale ndzeni.
2. Ku Sirhelela 'Thermal Core' leyi nga Fragile.
Yitirha tani hi nhlonge yo tiya, yo olova, yinyika ku tiya ka ku khwaxa, ku tsandzeka ku handzuka, na nsirhelelo wo ambala eka ti films ta aluminized polyimide letinga ehansi leti olovaka swinene naswona ti onhakaka hiku olova. Leswi switiyisisa vutshembeki bya multi-layer vacuum insulation naswona swisivela ku tsandzeka ka mahiselo leswi vangiwaka hiku onhaka ka leyara yale handle.
III. Mpfuneto wa ku Famba-famba na Swihlawulekisi swa Vuhlayiseki bya Tikhemikhali
1. Swihlawulekisi swa Friction yale hansi na Anti-Tangling
Coefficient yale hansi swinene ya friction ya PTFE surface yinyika lapi rale handle swihlawulekisi leswinga namarheli, swo olova. Loko va-astronaut va gombonyokisa mavoko kumbe mahlangano ya torso, ti layers ati siveli ku famba kumbe ku endla ti tangles hikokwalaho ka friction yale henhla, leswi tiyisisaka ku olova hi nkarhi wa migingiriko yale handle ka movha, tani hileswi swinga kombisiwa hi vaendli va malapi ya mahiselo yale henhla ya Teflon.
2. Ku sivela malangavi na ku nga tirhi ka tikhemikhali
Lapi ra fiberglass base hi ntumbuluko ari hiseki, naswona PTFE coating ayi pfurhile malangavi naswona yitshamisekile swinene hi ti khemikhali, yikota ku lwisana na erosion kusuka eka switirhisiwa swo tiya swa oxidizing swofana na atomic oxygen eka xibakabaka. Eka tindzhawu leti tirhisiwaka hi matimu ta pure-oxygen cabin, ku sivela malangavi loku xikan’we naku lwisana na corrosion aswiri swa nkoka swinene eka vuhlayiseki bya va-astronaut.
IV. Matirhiselo ya Swilo swa nkoka na Nhluvukiso wa Manguva Lawa
1. Lapi ra Beta eka Nguva ya Apollo – Ri Kombisiwile hi Xiendlo
Ti Apollo A7L lunar spacesuits ti tirhise ngopfu lapi ra Beta eka leyara yale handle, ti tiyisela hiku humelela mahiselo ya vuandlalo bya n’weti kutlula 100°C, ku thyakisa ka ntshuri wa n’weti lowu dlayaka (vuandlalo byo olova bya PTFE byi lwisana na ku namarhela ka ntshuri naswona swa olova ku byi basisa), na ku khumbeka ka micrometeoroid. Leswi swi tiyisisile ku tshembheka ka yona eka tindzhawu hinkwato na mahiselo yo tlula mpimo.
2. Ku hundzuka ku ya eka Ortho-Fabric eka ti-EMU ta manguva lawa
Eka swisuti swa le xibakabakeni leswi tirhisiwaka eka Space Shuttle na International Space Station, leyara ya le handle yi hundzukile ku va ku hlanganisiwa ka Ortho-fabric. Yi lukiwile kusuka eka ti fibre leti andlariweke ta PTFE (Gore-Tex), Nomex, na Kevlar. Eka xisekelo xa yona, yaha titshege hi Teflon-based weatherability, dust resistance, xikan’we naku tiyisela mahiselo yale henhla, loko yikatsa ti fibre tin’wana kuva yi tlakusa matimba xikan’we naku sivela malangavi. Yi hundzuke xisirhelelo xo hetelela xa le handle lexi hlanganisaka nsirhelelo wa ku hisa, nsirhelelo wa michini ni ku pfuneta ku famba-famba.
Loko u lava ku dyondza swo tala hi vuxokoxoko bya swihlawulekisi, swiyimo swa xikombelo, na tindlela to endla hi ku landza swilaveko swa switirhisiwa swa hina hinkwaswo—ku katsa na malapi ya Teflon ya mahiselo ya le henhla, thepi ya mahiselo ya le henhla ya Teflon, mabandhi ya mesh ya mahiselo ya le henhla ya Teflon, mabandhi ya muchini wo namarhela lama nga riki na swirhabyani, malapi ya PTFE ya tlhelo rin’we, mabandhi yo fambisa ya mahiselo ya le henhla, na malapi ya fiberglass ya mahiselo ya le henhla—hi kombela u ntshunxeka ku hi tihlanganisa hi ku tirhisa:
Hi tshama hi ri karhi hi seketela filosofi ya vukorhokeri leyi fambiwaka hi xiphurofexinali na vutshembeki, naswona hi tinyiketerile ku ku nyika swintshuxo swa xiyimo xin’we na vukorhokeri lebyi nga na vuxiyaxiya!
