Nā noi ʻo PTFE i uhi ʻia

Aegis, Aflas, Butyl, Fluorosilicone, Hypalon a i ʻole kekahi mea hoʻohui i koi ʻia i kāu noi kikoʻī.ʻO Coated a me Encapsulated O-Rings kekahi koho ʻē aʻe:

Hoʻopili ʻia a hoʻopaʻa ʻia paha - Hoʻopili ʻia nā O-Rings i uhi ʻia, me ka uhi ʻana e pili ana i ka O-Ring (maʻamau ʻo Silicone a i ʻole Viton a i ʻole NBR).ʻO nā O-Ring i hoʻopaʻa ʻia he O-Ring (maʻamau ʻo Silicone a i ʻole Viton) i uhi ʻia me kahi paipu PTFE.ʻO ka uhi ʻana o PTFE o O-Rings kahi ʻāpana haʻahaʻa haʻahaʻa maikaʻi loa kahi e noʻonoʻo nui ai ka maʻalahi o ka hana.ʻO ka encapsulated O-Ring e like me ka wai viscous kiʻekiʻe, hoʻouna ʻia kekahi kaomi ma ka sila ma nā ʻaoʻao āpau.Loaʻa nā O-Rings i uhi ʻia i nā kala ākea.
Nā hui kūikawā o nā mea - Inā loaʻa iāʻoe kahi koi no kahi hui kūikawāʻaʻole i ka maʻamau o kaʻoihana maʻamau, hiki iā mākou ke hana pū me nā mea hana e hana i kēlā hui kūikawā e kūpono i kāu mau pono.
ʻO Mil-Spec, Mil-Std a i ʻole Milspecs kahi maʻamau pale ʻAmelika Hui Pū ʻIa i hoʻohana ʻia no ka hoʻokō ʻana i nā pahuhopu standardization e ka US Department of Defense.Hiki i nā Rockets Seals ke hoʻopuka i nā Mil-Spec ma o kā mākou pūnaewele nui o nā mea hoʻolako kaulana.
ʻO nā mea ʻai meaʻai FDA, nā inoa haole, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) a me Mil-Spec - Loaʻa iā Rocket ka ʻike me ka hoʻokō ʻana i kāu mau pono ma nā kūlana ʻoihana āpau.

Hiki iā ʻoe ke koho i ke kala a i ʻole nā kala ʻē aʻe.

ʻOi aku ka maikaʻi ma ka inoa inoa ʻo Teflon, polytetrafluoroethylene (PTFE) hāʻawi i kahi ʻili nonstick no ka mea kuke, ka nail polish, nā mea hana lauoho, ka mālama lole/kāpena, a me nā lau wiper windshield.Eia nō naʻe, ke ʻike nei nā mea hana i ka hoʻonui ʻana i nā pōmaikaʻi mai ka hoʻohana ʻana i ka PTFE ma ke ʻano he ala e hana ai i nā O-rings maikaʻi.Na apo-okūkulu ʻia me ka hoʻohana ʻana i ka PTFE e hāʻawi i ka insulation thermal a me kemika, a hiki iā lākou ke pale i ka friction a me ka wai pū kekahi.

PTFE VERSUS TEFLON

ʻOiai ʻokoʻa lākou i ka branding, ʻokoʻa ka PTFE a me Teflon i kahi kumu maʻamau a me nā waiwai.

PTFE

ʻO ka PTFE he polymer synthetic i loaʻa mai i ka hoʻopaʻa ʻana i nā kemika ma waena o ke kalapona a me ka fluorine, e hoʻohana ana i ka makemake o nā radical manuahi e polymerize me ka tetrafluoroethylene.Ua ʻike ʻia kēia mea i ka makahiki 1938, i ka wā i hoʻāʻo ai ʻo DuPont chemist Roy J. Plunkett e hana i kahi ʻano hou o ka refrigerant, a hui pū i kēia mau mea me ka ʻike ʻole i ka hopena e hiki mai ai.

TEFLON

ʻO Kinetic Chemicals, he hui hui ma waena o DuPont a me General Motors, i hoʻopaʻa inoa ʻia ʻo PTFE ma lalo o ka inoa inoa Teflon i ka makahiki 1945. ʻO ke kumu, ʻo Teflon ka PTFE.Eia nō naʻe, loaʻa ka PTFE ma lalo o nā inoa inoa inoa ʻē aʻe, e like me:

Daikin-Polyflon
Fluon
ʻO Dyneon

NA WAIWAI

Hoʻokaʻawale kekahi mau waiwai i ka PTFE mai nā mea ʻē aʻe, me:

ʻO ka helu haʻahaʻa haʻahaʻa: ʻO ka PTFE ke kolu o ka helu haʻahaʻa haʻahaʻa haʻahaʻa loa o kekahi mea i ʻike ʻia e ke kanaka, ʻo ia hoʻi ʻo ia maoli.
Hana ʻia ma ka wela wela: Ua helu ʻia ma 600 K, hoʻoheheʻe ʻia ka PTFE ma 327ºC a i ʻole 620ºF, a hana maikaʻi nō hoʻi ia ma nā wela haʻahaʻa e like me −268ºC a i ʻole −450ºF.
Kū'ē i ka wai: Piʻi ka wai ma luna o ka ʻili o PTFE, ʻo ia hoʻi, ʻo nā ʻili i mālama ʻia me kēia mea e pale aku i ka hoʻohemo ʻana.
Nonreactive: ʻAʻole pane ʻo PTFE me ka hapa nui o nā mea corrosive, no laila kūpono ia no ka hoʻohana ʻana i nā paipu, nā pahu, nā sila, a me nā apo-O.

KA MAHELE KIEKIE O PTFE

ʻO ka pae wela (-1,000F a +4,000F), nonreactivity, kūʻē wai, a me nā waiwai friction haʻahaʻa o PTFE e lilo ia i mea kūpono no ke kūkulu ʻana i nā apo-O no ka hoʻohana ʻana i nā ʻano noi like ʻole.ʻO kēia mau waiwai e hoʻolilo iā PTFE O-rings i koho maikaʻi loa no nā noi kū i ka wā a me nā noi e pili ana i ka uila a me ka insulation thermal.

Ma muli o ko lākou nui,Nā apo-O PTFEʻaʻole "hoʻoheheʻe ʻia" - akā, ua hoʻopili ʻia a hoʻopaʻa ʻia e hāʻawi i ke ʻano kūpono.
