He alakai piha no na uwea wela wela o Teflon

2. Nā ʻano kumu a me nā pono

ʻO ke kumu i hoʻomaikaʻi nui ʻia ai ka uea Teflon ma ke ʻano molekala kū hoʻokahi o ka mea ponoʻī (nā paʻa kalapona-fluorine ikaika loa). ʻO kāna mau hiʻohiʻona nui:

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

(2). Hana Uila Kūlana:
Ka ikaika dielectric kiʻekiʻe: hiki ke kū i ka uila kiʻekiʻe loa me ka ʻole o ka haki ʻana, ka hana insulation maikaʻi loa.
Haʻahaʻa dielectric mau a me ka haʻahaʻa dielectric poho: ʻoiai ma lalo o ke alapine kiʻekiʻe, ʻoi aku ka liʻiliʻi o ka hoʻouna ʻana i ka hōʻailona, ​​​​pono ia no ka ʻikepili kiʻekiʻe a me ka hoʻouna ʻana i ka hōʻailona RF.

(3). Paʻa Kemika ikaika:
Aneane ʻaʻole i hoʻopilikia ʻia e nā ʻakika ikaika, nā alkali ikaika, nā mea hoʻoheheʻe organik, a i ʻole nā ​​aila, me ke kūpaʻa maikaʻi loa. ʻAʻole ia e pōʻino ke hoʻolapalapa ʻia i loko o ka wai regia.

(4). Nā Pono Mechanical maikaʻi loa:
Haʻahaʻa friction coefficient: ʻili maʻemaʻe, lāʻau ʻole, maʻalahi i ke kaula, a ʻaʻole pili i ka lepo.
ʻO ke kūpaʻa ahi maikaʻi: kū i ka helu UL94 V-0 pale ahi, hoʻopau iā ia iho ke wehe ʻia mai ke ahi, palekana kiʻekiʻe.
Anti-kahiko a me ka UV kū'ē: mālama i ka lōʻihi o ka hana paʻa i nā wahi paʻakikī, lōʻihi ke ola lawelawe.

(5). Nā Pono ʻē aʻe:
Haʻahaʻa haʻahaʻa loa o ka wai, ʻaneʻane ʻaʻohe.
ʻAʻohe mea ʻawaʻawa a ʻaʻohe pōʻino, hoʻokō i nā palapala hōʻoia olakino a me nā meaʻai (e laʻa, USP Class VI, FDA), kūpono i nā mea lapaʻau a me nā meaʻai.

3. Nā 'ano a me nā 'ano ma'amau

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

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

(2). Ma ka hale:
ʻO ke kaula kumu hoʻokahi: ka mea alakaʻi (paʻa a paʻa paha) i uhi ʻia me ka insulation Teflon. ʻO ka hale paʻa, hoʻohana mau ʻia no ka wili paʻa.
Uea pale nui-nui: nui na core insulated i wili pu ia, i wili ia me ka alumini pepa a me ka pale keleawe keleawe, me ka puu waho. E pale pono i ka EMI, hoʻohana ʻia no ka hoʻouna ʻana i ka hōʻailona pololei.
ʻO ke kaula Coaxial: aia i kahi alakaʻi kikowaena, insulation, pale, a me ka sheath, i hoʻohana ʻia no ka hoʻouna RF kiʻekiʻe.

4. Nā kahua noi nui

Ma muli o kāna hui hoʻokō kū hoʻokahi, ua lilo ʻo Teflon wire i mea koho maikaʻi loa no nā noi kiʻekiʻe a koi.

(1). Aerospace a me ka Koa: ka uwea kūloko o nā mokulele, rockets, satellites, control system, radar system, etc.

(2). Lapaʻau Lapaʻau: nā mea hana diagnostic (CT, MRI), nā mea hana, nā mea analytical, nā mea hana sterilization, a me nā mea'ē aʻe.

(3). Hana Hana Hana:
ʻO nā kaiapuni wela kiʻekiʻe: nā kaula mīkini hoʻoheheʻe, nā mea wela, nā umu, nā paila, nā mīkini ea wela.
Nā noi kiʻekiʻe: nā mīkini hoʻopaʻa kiʻekiʻe kiʻekiʻe, nā mea kani ultrasonic, nā mea hānai kahua kamaʻilio.

(4). Electronics and Communications: high-frequency data cables, RF coaxial cables, uea kūloko o nā mea pono, nā lako hana semiconductor.

(5). ʻOihana Kaʻa: nā mea hoʻopaʻa uila kiʻekiʻe i loko o nā pūʻolo uila kaʻa kaʻa hou, nā uwea pili kaʻa, nā mea ʻike. Pono ka wela kiʻekiʻe a me ke kūpaʻa kiʻekiʻe.

(6). Nā mea hana hale: nā wili o loko o nā ʻāpana hoʻomehana i nā hao, nā umu microwave, nā mea hoʻoheheʻe ea, nā umu, etc.

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 wela kiʻekiʻe o ka wā pōkole.
Voltage: hoʻoholo i ka volta hana a kū i ka pae uila.
Kaiapuni kemika: ka ʻike ʻana i nā ʻaila, nā mea hoʻoheheʻe, nā waikawa, nā kumu.
Kaiapuni mīkini: kulou, abrasion, koi tensile.

(2). Nā palapala hōʻoia a me nā kūlana:
E koho i nā uea i kūpono i nā kūlana kūpono (UL, CSA, CE, RoHS) e like me nā mākeke hoʻokuʻu aku a me nā kahua noi. No nā lāʻau lapaʻau a me nā meaʻai, pono nā palapala hōʻoia kūpono.

(3). Ka maikaʻi o ka uea:
Conductor: keleawe maʻamau a i ʻole keleawe ʻole. Hoʻomaikaʻi ke keleawe tinned i ka pale ʻana a me ka solderability. E nānā i ka ʻōlinolino a me ka paʻa paʻa.
Insulation: ʻO ka uea Teflon maoli e hoʻopau iā ia iho ma hope o ka wehe ʻana i ke ahi, ʻo ka lapalapa ʻōmaʻomaʻo e hōʻike ana i ka fluorine, e ʻā ana i loko o nā puʻupuʻu me ke kaha ʻole. Ke hoʻomau nei nā plastik maʻamau i ke ahi me ka filament.
Ka paʻi ʻana: maʻemaʻe, pale ʻaʻahu, me nā specs, standards, certifications, manufacturer.

(4). Kumukuai noonoo:
ʻOi aku ke kumukūʻai o ka uea Teflon ma mua o nā uwea maʻamau. E koho i ka papa kūpono e kaulike i ka hana a me ke kumukūʻai.

6. Ka hopena

Me kona kiʻekiʻe kiʻekiʻe wela kū'ē, corrosion kū'ē, kiʻekiʻe insulation, a me ka paʻa, Teflon uea ua lilo i mea indispensable i loko o kiʻekiʻe-hopena hana a me ka 'enehana kahua. ʻOiai ke kumukūʻai kiʻekiʻe, ʻo kona palekana, hilinaʻi, a me ke ola lawelawe lōʻihi e lawe mai i ka waiwai hiki ʻole ke hoʻololi. ʻO ke kī i ka hopena maikaʻi loa ʻo ka hoʻomaopopo piha ʻana i kāu pono noi noi a kamaʻilio pū me nā mea hoʻolako hilinaʻi.

E pili ana i KEKAHI AO

HOOKAHI AOe kālele ana i ka hāʻawi ʻana i nā mea maka kiʻekiʻe no nā uea a me nā kaula, e komo pū me nā mea insulation fluoroplastic, nā lipine metala, a me nā fibers hana. Loaʻa i kā mākou huahana nā mea insulation fluoroplastic no nā uea kūʻokoʻa kiʻekiʻe, a meWai Paʻa Wai, Mylar Tape, Copper Tape, a me nā mea uwea kī ʻē aʻe. Me ka maikaʻi paʻa a me ka hāʻawi pono ʻana, hāʻawi mākou i ke kākoʻo ikaika no ka hana ʻana i nā uea kūʻokoʻa kiʻekiʻe 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 wahi paʻakikī.
