Monga katswiri wopanga PTFE zomatira tepi ndi zinthu zosungunulira zogwirizana, Jiangsu Aokai New Materials Technology Co., Ltd. amagawana chidziwitso chofunikira. Ngakhale tepi yotentha kwambiri ya PTFE imayamikiridwa chifukwa cha mphamvu zake zabwino kwambiri za dielectric komanso kukhazikika kwamafuta, nkhanza zapanthawi yayitali komanso zowotcha kwambiri zimabweretsa zoopsa zingapo.
Kumvetsetsa zoopsazi - kuphatikizapo ukalamba wotentha kwambiri, kuwonongeka kwa magetsi, kutayika kwafupipafupi, ndi zochitika zachilengedwe - ndizofunikira pakupanga dongosolo lodalirika.
Kuopsa kwa Mphamvu Zamagetsi
Kuwonongeka Kwamphamvu Kwambiri: Matepi a PTFE ali ndi kukana kwapang'onopang'ono kwa dielectric. Mwachitsanzo, tepi yokhala ndi makulidwe okwana 0.11mm ikhoza kukhala ndi mphamvu yowononga pafupifupi 6.1kV. Kusakwanira kokwanira kapena zonyansa zamkati (zobowo, zowononga) zitha kuyambitsa kuwonongeka kwamphamvu kwambiri komanso kulephera kwa insulation.
Kutulutsa Mwapang'ono (Kutuluka kwa Corona): M'malo okhala ndi mphamvu zambiri, zonyansa (fumbi, madontho amafuta) ndi timipata tating'ono ta mpweya tating'onoting'ono tamkati timapanga malo ofikira magetsi, zomwe zimayambitsa kutulutsa kwa corona. Kutulutsa kosalekeza kwa nthawi yayitali pang'onopang'ono kumawononga wosanjikiza wotsekera, zomwe zimapangitsa kulephera msanga.
Kuwonongeka kwa Insulation kuchokera ku Environmental Factors:
Chinyezi: Chinyezi chikapitilira 85%, mphamvu ya PTFE imatha kutsika kwambiri - kuchokera pa 10⊃1;⁷Ω mpaka pafupifupi 10⊃1;⊃2;Ω - ndipo voteji yosweka imatha kutsika ndi 30% mpaka 50%.
Zoipitsidwa: Fumbi loyendetsa kapena utsi wamchere pa tepi pamwamba pa tepi umapanga milatho yochititsa chidwi, kupanga njira zapano zotayikira.
Pazida zamagetsi zamphamvu kwambiri, mphamvu ya dielectric ya matepi a PTFE simtengo wokhazikika koma zimadalira kwambiri momwe mungagwiritsire ntchito. Kwa magiredi osamva corona, opanga nthawi zambiri amaphatikiza zodzaza ndi inorganic monga mica kapena ceramic particles mu PTFE matrix. Zodzaza izi zimapanga ma micro-interface angapo omwe amabalalitsa ndende ya charger ndikulepheretsa kutulutsa pang'ono. Posankha PTFE tepi kwa mkulu-voteji inverter Motors (mwachitsanzo, 6kV kuti 10kV kalasi), tikulimbikitsidwa kugwiritsa corona zosagwira PTFE tepi ndi makulidwe osachepera 0.18mm ndi kutsimikizira tsankho kumaliseche inception voteji (PDIV) pansi pa kutentha kwenikweni opaleshoni, monga PDIV zambiri amachepetsa ndi 530 chipinda 530 ° C poyerekeza 20- 20- chipinda.
Zowopsa Zakukhazikika kwa Matenthedwe
Ukalamba Wotentha Kwambiri: Matepi a PTFE amatha kugwira ntchito mokhazikika pa kutentha kosalekeza kwa 260°C. Komabe, kutentha kukapitirira 250 ° C (makamaka pafupi ndi 300 ° C), maunyolo a maselo amayamba kuwola. Kuwola kumeneku kumachepetsa kwambiri mphamvu ya dielectric ndipo kumapangitsa kuti pakhale ngozi zolephereka.
Thermal-Oxygen Synergistic Effect: Kuphatikiza kutentha kwambiri ndi mpweya kumathandizira kukalamba kwakuthupi. Pakutentha ndi chinyezi, kuwonongeka kwa magwiridwe antchito amagetsi kumatha kuwonjezeka ndi 30% mpaka 50% poyerekeza ndi kutentha kowuma kokha.
Pamene tepi ya PTFE ikugwiritsidwa ntchito muzitsulo zotsekedwa kapena ma thiransifoma ma windings kumene mpweya uli wochepa, khalidwe la ukalamba wotentha limasiyana kwambiri ndi malo otsegula. Kafukufuku amasonyeza kuti PTFE a matenthedwe kuwola mlingo nayitrogeni pafupifupi gawo limodzi mwa magawo khumi mu mpweya pa kutentha chomwecho. Izi zikutanthauza kuti kwa hermetically losindikizidwa zigawo mkulu-voltage, PTFE tepi akhoza kukwaniritsa moyo wautali utumiki ngakhale pa kutentha pang'ono pamwamba 260 °C. Komabe, kuwonongeka kukayamba, zinthu zomwe zimapangidwanso monga carbonyl fluoride ndi perfluoroisobutylene zimakhala zapoizoni kwambiri komanso zimawononga zitsulo. Chifukwa chake, ndikofunikira kuwonetsetsa kuti kutentha kwa ntchito kumakhalabe pansi pa gawo la kuwonongeka - malire achitetezo a 30-50 ° C akulimbikitsidwa kuti azitha kutenthetsa kwambiri.
Zowopsa Zazigawo Zapamwamba
Kuyimitsidwa kwa Signal ndi Kusokoneza: Dielectric constant (Dk) ya PTFE wamba kuyambira 2.0 mpaka 2.6. Zogulitsa zomwe zimapatuka kwambiri mu Dk zitha kupangitsa kuchepetsedwa ndi kusokoneza kwa ma siginecha apamwamba kwambiri pakupatsirana - nkhani yovuta kwambiri pakugwiritsa ntchito ma RF ndi ma microwave.
Kutentha kwa Kutentha: PTFE ili ndi tangent yotsika kwambiri ya dielectric (tan δ), nthawi zambiri imakhala pansi pa 0.0025. Komabe, ngati chiwongoladzanja chiri chapamwamba kwambiri (chifukwa cha zonyansa kapena kukonzedwa kosayenera), kutentha kwakukulu kudzapangidwa pansi pa magetsi othamanga kwambiri. Kudziwotcha kumeneku kumathandizira kukalamba kwakuthupi ndipo kungayambitse kuthawa kwamafuta.
Zowopsa Zamakina & Zosintha Zachilengedwe
Kuwonongeka kwa Kupsinjika Kwamakina: Kukangana kosalekeza ndi kukangana pakuyika kapena kugwiritsa ntchito kungayambitse ming'alu yaying'ono ndi ma abrasion mkati mwazinthu, kuwononga magwiridwe antchito onse. Kupindika kapena m'mbali zakuthwa kuyenera kupewedwa.
Chemical & Radiation Corrosion: Zida zowononga zamphamvu monga zitsulo zosungunuka za alkali ndi ma hydrocarboni a chlorinated, komanso ma radiation amphamvu kwambiri (opitilira 10⁴ Gy), awononga mamolekyu a PTFE ndikuchepetsa kwambiri mphamvu yake ya dielectric.
Kugwiritsa ntchito tepi yomatira ya PTFE pamakina othamanga kwambiri komanso othamanga kwambiri kumafuna kuwunika mosamala zinthu zingapo zoopsa. Pomvetsetsa malire a mphamvu zamagetsi, khalidwe la ukalamba wotentha, mphamvu za dielectric zapamwamba kwambiri, komanso kukhudzidwa kwa chilengedwe, akatswiri amatha kusankha tepi yoyenera - kapena kupempha mayankho osinthidwa - kuti apewe kulephera msanga.
Monga wopanga matepi odalirika a PTFE , Aokai imapereka zinthu zofananira zomwe zimafunikira kuti azipaka magetsi pansalu zonse za PTFE, lamba wa PTFE, lamba wa PTFE, tepi ya filimu ya PTFE, ndi tepi ya PTFE fiberglass..
Zomwe zili pamwambapa zimaperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.
Kuti mudziwe zambiri zaukadaulo, mayankho ogwiritsira ntchito, ndi ntchito zosinthidwa pazogulitsa zathu zonse kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi ya PTFE yotentha kwambiri, lamba wa PTFE wotentha kwambiri, lamba wamakina osasunthika, nsalu imodzi ya PTFE, lamba wonyamula kutentha kwambiri komanso nsalu yosagwira kutentha ya fiberglass , chonde titumizireni momasuka:
Timamamatira ku nzeru zamabizinesi za ukatswiri ndi umphumphu, ndipo tadzipereka kuti tipereke mayankho odalirika amtundu umodzi ndi ntchito zolingalira kwa makasitomala onse.
