He Alakaʻi Piha i nā Uea Mahana Kiʻekiʻe Teflon

2. Nā ʻano koʻikoʻi a me nā pono

ʻO ke kumu i mahalo nui ʻia ai ka uea Teflon ma muli o ke ʻano molekala kūikawā o ka mea ponoʻī (nā pilina kalapona-fluorine ikaika loa). ʻO kona mau ʻano nui:

(1). Kū'ē Mahana Kiʻekiʻe Maikaʻi Loa:
ʻO ka laulā o ka mahana hana: hiki i nā huahana maʻamau ke hana mau mai -65°C a i +200°C (ʻoiai +260°C), a ʻo ke kū'ē pōkole hiki ke ʻoi aku ma mua o 300°C. ʻOi aku kēia ma mua o nā palena o ka PVC maʻamau (-15°C a i +105°C) a me ke kaula silicone (-60°C a i +200°C).

(2). Hana Uila Koʻikoʻi:
Ikaika dielectric kiʻekiʻe: hiki ke kū i ke ana uila kiʻekiʻe loa me ka ʻole o ka haki ʻana, hana insulation maikaʻi loa.
ʻO ke kūpaʻa dielectric haʻahaʻa a me ka pohō dielectric haʻahaʻa: ʻoiai ma lalo o ke alapine kiʻekiʻe, he liʻiliʻi ka pohō hoʻoili hōʻailona, ​​​​​​e kūpono ia no ka ʻikepili alapine kiʻekiʻe a me ka hoʻoili hōʻailona RF.

(3). Paʻa Kemika Ikaika:
ʻAneʻane ʻaʻole i hoʻopilikia ʻia e nā waikawa ikaika, nā alkalis ikaika, nā mea hoʻoheheʻe organik, a i ʻole nā ​​​​ʻaila, me ke kūpaʻa maikaʻi loa i ka pala. ʻAʻole ia e pala ʻoiai ke hoʻolapalapa ʻia i loko o ka aqua regia.

(4). Nā Waiwai Mekanika Maikaʻi Loa:
Ka helu haʻahaʻa haʻahaʻa: ʻili laumania, ʻaʻole e pipili, maʻalahi ke kaula, a ʻaʻole pili i ka lepo.
Ke kūpaʻa lapalapa maikaʻi: hoʻokō i ka helu pale lapalapa UL94 V-0, hoʻopau ponoʻī ke wehe ʻia mai ke ahi, palekana kiʻekiʻe.
Kū'ē i ka ʻelemakule a me ka pale UV: mālama i ka paʻa o ka hana lōʻihi i nā ʻano ʻino, ke ola lōʻihi o ka lawelawe.

(5). Nā Pōmaikaʻi ʻē aʻe:
Haʻahaʻa loa ka omo ʻana o ka wai, ʻaneʻane ʻaʻohe.
ʻAʻohe mea ʻawahia a ʻino ʻole hoʻi, kūlike me nā palapala hōʻoia lapaʻau a me ka pae meaʻai (e laʻa, USP Class VI, FDA), kūpono no nā lako lapaʻau a me ka meaʻai.

3. Nā ʻAno a me nā ʻAno Maʻamau

Hiki ke hoʻokaʻawale ʻia ke uea Teflon ma nā ʻano like ʻole e like me kona ʻano, mea, a me nā kūlana:

(1). Ma o ka mea hoʻokaʻawale:
PTFE (Polytetrafluoroethylene): ka mea maʻamau, me ka hana piha loa, akā paʻakikī ke hana (pono ka sintering).
PFA (Perfluoroalkoxy): hana like me PTFE, akā hiki ke hana ʻia e ka extrusion heheʻe, ʻoi aku ka kūpono no ka hana ʻana i ka insulation paia lahilahi.
FEP (Fluorinated Ethylene Propylene): ke kiʻekiʻe o ka moakāka, maikaʻi ke kaʻina hana hoʻoheheʻe.

(2). Ma ke ʻano hana:
Uea hoʻokahi-ʻiwi: alakaʻi (paʻa a wili paha) i uhi ʻia me ka insulation Teflon. Kūkulu paʻa, hoʻohana pinepine ʻia no nā uea paʻa.
Uea pale ʻia me nā ʻano he nui: nā ʻano ʻāpana he nui i hoʻopaʻa ʻia i wili pū ʻia, i wahī ʻia me ka pepa alumini a me ka pale ulana keleawe, me kahi ʻūpā waho. Kūʻē maikaʻi i ka EMI, hoʻohana ʻia no ka hoʻoili hōʻailona pololei.
Uaea coaxial: aia i loko o kahi alakaʻi waena, kahi mea hoʻomehana, kahi pale, a me kahi ʻūpā, i hoʻohana ʻia no ka hoʻoili RF alapine kiʻekiʻe.

4. Nā Kahua Noi Nui

Ma muli o kāna hui hana kūikawā, ua lilo ka uea Teflon i koho makemake ʻia no nā noi kiʻekiʻe a koi nui:

(1). Aerospace a me ka Koa: nā uwea kūloko o nā mokulele, nā rockets, nā satelite, nā ʻōnaehana hoʻomalu, nā ʻōnaehana radar, a me nā mea ʻē aʻe. Pono nā mea māmā, kūpaʻa i ka mahana kiʻekiʻe, a hilinaʻi nui ʻia.

(2). Nā Lako Lapaʻau: nā lako hana hōʻoia (CT, MRI), nā mea hana ʻoki kino, nā mea hana loiloi, nā lako hana sterilization, a pēlā aku. Pono ka mea ʻawahia ʻole, kū i nā disinfectants, a me ka hilinaʻi kiʻekiʻe.

(3). Hana Hana ʻOihana:
Nā wahi wela kiʻekiʻe: nā kaula mīkini wili, nā mea hoʻomehana, nā umu, nā paila, nā mīkini ea wela.
Nā hoʻohana alapine kiʻekiʻe: nā mīkini sila alapine kiʻekiʻe, nā hāmeʻa ultrasonic, nā mea hānai kikowaena kamaʻilio.

(4). Nā Uila a me nā Kamaʻilio: nā kaula ʻikepili alapine kiʻekiʻe, nā kaula coaxial RF, nā uea kūloko o nā mea hana pololei, nā lako hana semiconductor.

(5). ʻOihana Kaʻa: nā kāʻei uila kiʻekiʻe i loko o nā pā uila kaʻa ikehu hou, nā uea hoʻohui motika, nā kāʻei sensor. Pono ke kū'ē ʻana i ka mahana kiʻekiʻe a me ke uila kiʻekiʻe.

(6). Nā Mea Hana Hale: nā uea kūloko o nā ʻāpana hoʻomehana i loko o nā hao, nā umu microwave, nā mea hoʻomoʻa ea, nā umu, a pēlā aku.

5. Pehea e koho ai i ka uea Teflon?

I ke koho ʻana, e noʻonoʻo i nā kumu aʻe:

(1). Kaiapuni Hana:
Mahana: e hoʻoholo i ka mahana hana lōʻihi a me ka mahana kiʻekiʻe pōkole hiki.
Uila uila: e hoʻoholo i ke uila hana a kū i ka pae uila.
Kaiapuni kemika: ka ʻike ʻana i nā aila, nā mea hoʻoheheʻe, nā waikawa, nā kumu.
Kaiapuni mīkini: kūlou, ʻāʻī ʻana, nā koi tensile.

(2). Nā Palapala Hōʻoia a me nā Kūlana:
E koho i nā uea e kūlike me nā kūlana kūpono (UL, CSA, CE, RoHS) e like me nā mākeke hoʻokuʻu aku a me nā kahua noi. No nā lako lapaʻau a me ka meaʻai, he mea pono nā palapala hōʻoia kūpono.

(3). Ka maikaʻi o ke kaula uila:
Alakaʻi: ʻo ka maʻamau he keleawe tin a he keleawe ʻōlohelohe paha. Hoʻomaikaʻi ke keleawe tin i ke kūpaʻa ʻana i ka oxidation a me ka solderability. E nānā i ka ʻālohilohi a me ke kaula paʻa.
Palekana: pio ponoʻī ke uea Teflon maoli ma hope o ka wehe ʻana i ka lapalapa, hōʻike ka lapalapa ʻōmaʻomaʻo i ka fluorine, puhi i loko o nā puʻupuʻu me ka ʻole o ke kaha ʻana. Hoʻomau ka puhi ʻana o nā plastik maʻamau me ke kaula.
Paʻi ʻana: moakāka, kūpaʻa i ke komo ʻana, me nā kikoʻī, nā kūlana, nā palapala hōʻoia, ka mea hana.

(4). Nā Manaʻo Kumukūʻai:
ʻOi aku ke kumukūʻai o ka uea Teflon ma mua o nā uea maʻamau. E koho i ke ʻano kūpono e kaulike ai i ka hana a me ke kumukūʻai.

6. Hopena

Me kona kūpaʻa wela kiʻekiʻe, kūpaʻa i ka pala, ka insulation kiʻekiʻe, a me ke kūpaʻa, ua lilo ka uea Teflon i mea pono ʻole i nā ʻoihana ʻoihana a me nā ʻenehana kiʻekiʻe. ʻOiai ke kumukūʻai kiʻekiʻe, ʻo kona palekana, ka hilinaʻi, a me ke ola lawelawe lōʻihi e lawe mai i ka waiwai hiki ʻole ke hoʻololi ʻia. ʻO ke kī i ka hopena maikaʻi loa, ʻo ia ka hoʻomaopopo piha ʻana i kāu mau pono noi a kamaʻilio me nā mea hoʻolako hilinaʻi.

E pili ana i HONUA HOʻOKAHI

HONUA HOʻOKAHIe kālele ana i ka hoʻolako ʻana i nā mea maka kiʻekiʻe no nā uea a me nā kaula, me nā mea hoʻohuihui fluoroplastic, nā lipine metala, a me nā olonā hana. ʻO kā mākou huahana e komo pū me nā mea hoʻohuihui fluoroplastic no nā uea kū i ke kiʻekiʻe o ka mahana, a meʻO ka olonā pale wai, Mylar Lipe, Copper Lipe, a me nā mea kaula koʻikoʻi ʻē aʻe. Me ke kūlana paʻa a me ka hoʻouna hilinaʻi, hāʻawi mākou i ke kākoʻo ikaika no ka hana ʻana i nā uea kū i ke kiʻekiʻe wela a me nā kaula like ʻole a me nā kaula optical, e kōkua ana i nā mea kūʻai aku e mālama i ka hilinaʻi o ka huahana a me ka hoʻokūkū ma lalo o nā ʻano ʻino.
