I. Mea Koʻikoʻi a me ka hoʻonohonoho ʻana i nā lole lewa
1. Hoʻohui: PTFE-Coated Fiberglass Fabric
Ma ke kahua aerospace, keia ʻO ka lole wela wela ʻo Teflon i kapa ʻia he lole Beta. Hoʻohana ia i ka lole fiberglass ikaika kiʻekiʻe e like me ka substrate, i hoʻopili ʻia a i uhi ʻia ma ka papa waho me ka polytetrafluoroethylene (PTFE, ʻo ia hoʻi, Teflon). Hoʻohui kēia i ka maʻalahi o ka lole me ka inertness extreme-environment o PTFE.
2. Ke kuleana: ʻO ka mea kaua o waho o ka Thermal Micrometeoroid Garment
Wahi a nā mea hana lole lole wela kiʻekiʻe ʻo Teflon: I loko o ka ʻōnaehana insulation multi-layer o extravehicular mobility units (EMUs), lawelawe ʻo ia ma ke ʻano o ka papa waho loa o ka Thermal Micrometeoroid Garment (TMG), e kū pono ana i ka vacuum, nā ʻokoʻa wela wela, a me nā micrometeoroids. Hana ʻo ia ma ke ʻano o ka pale kino a me ka wela no ka ʻumi a i ʻole nā papa o loko o nā kiʻi aluminized.
II. Kaiapuni wela loa a me ka pale kino
1. Ke kū ʻana i nā ʻokoʻa ʻokoʻa wela a me ka hoʻoheheʻe wela
Hiki i ka lole wela kiʻekiʻe ʻo Teflon ke kū lōʻihi i nā mahana mai -200 ° C a + 260 ° C, e uhi ana i nā loli koʻikoʻi ma luna o 120 ° C ma ka ʻaoʻao e kū pono ana i ka lā a i lalo i -160 ° C ma ka ʻaoʻao malu. Hōʻike maikaʻi kona ʻili keʻokeʻo maʻamau i ka hoʻoheheʻe ʻana o ka lā, e hōʻemi nui ana i ka lawe ʻana i ka wela a mālama i ka paʻa o ka wela o loko.
2. Ka pale ʻana i ka 'Thermal Core' palupalu.
Hana ia e like me ka ʻili paʻakikī a maʻemaʻe, e hāʻawi ana i ka pale ʻana, ka pale ʻana i ka waimaka, a me ka pale ʻana i ka pale no nā kiʻiʻoniʻoni polyimide aluminized maʻalahi loa. Mālama kēia i ka pono o ka multi-layer vacuum insulation a pale i ka hāʻule ʻana o ka wela ma muli o ka pōʻino o waho.
III. Kokua Nei a me na Mea Hana Palekana
1. Nā Pono Kū'ē Haʻahaʻa a me nā Pono Kū'ē
ʻO ke koena haʻahaʻa haʻahaʻa o ka friction o ka ʻili PTFE e hāʻawi i ka lole o waho me nā ʻano lāʻau ʻole, nā hiʻohiʻona. I ka wā e kulou ai nā astronauts i ko lākou mau lima a i ʻole nā ʻāpana ʻūhā, ʻaʻole keakea nā papa i ka neʻe ʻana a i ʻole ka hana ʻana i nā kuʻekuʻe ma muli o ke kiʻekiʻe o ka friction, e hōʻoiaʻiʻo ana i ka maʻalahi i ka wā o nā hana extravehicular, e like me ka mea i hōʻike ʻia e nā mea hana lole wela wela ʻo Teflon.
2. Hoʻopaneʻe ʻia ke ahi a me ka ʻole o ke kino
ʻAʻole hiki ke puhi ʻia ke kumu fiberglass, a ʻo ka uhi PTFE he ahi-retardant a paʻa kemika, hiki ke pale aku i ka erosion mai nā mea oxidizing ikaika e like me ka oxygen atomic i ka lewa. I loko o nā kaiapuni o ka oxygen maʻemaʻe i hoʻohana mua ʻia, he mea koʻikoʻi kēia hōʻemi ʻana o ka lapalapa a me ka pale ʻana i ka corrosion i ka palekana astronaut.
IV. Nā noi Milestone a me ka Evolution Hou
1. ʻO ka lole Beta i ka wā ʻo Apollo - Hōʻike ʻia i ka hana
ʻO ka Apollo A7L lunar spacesuits i hoʻohana nui ʻia i ka lole Beta no ka ʻaoʻao o waho, e kū pono ana i ka ʻili o ka mahina ma luna o 100°C wela, ka lepo o ka mahina make (e kūʻē ka ʻili PTFE i ka lepo a maʻalahi e hoʻomaʻemaʻe), a me nā hopena micrometeoroid. Ua hōʻoia kēia i kona hilinaʻi ma nā ʻāina āpau a me nā wela wela.
2. Evolution i ka Ortho-Fabric i nā EMU hou
Ma nā lole ākea i hoʻohana ʻia no ka Space Shuttle a me ka International Space Station, ua ulu ka papa o waho i kahi hui Ortho-fabric. Ua ulana ʻia mai nā fibers PTFE (Gore-Tex) i hoʻonui ʻia, Nomex, a me Kevlar. Ma kona kumu, ke hilinaʻi mau nei ia i ka weatherability e pili ana iā Teflon, ka pale ʻana i ka lepo, a me ka hoʻomanawanui kiʻekiʻe, ʻoiai e hoʻopili ana i nā fibers e hoʻonui ai i ka ikaika a me ka retardancy ahi. Ua lilo ia i mea pale kaua hope loa e hoʻohui i ka pale wela, ka pale mechanical, a me ke kōkua neʻe.
Ke kākoʻo mau nei mākou i kahi ʻatikala lawelawe ʻoihana a me ka pololei, a ua hoʻolaʻa ʻia i ka hāʻawi ʻana iā ʻoe i nā hopena hoʻokahi a me ka lawelawe hoʻolohe!
