Ungalokothi ucabange ukuthi i-polyimide tape inalezi zinzuzo

Itheyiphu ye-Polyimide, eyaziwa nangokuthi i-Kapton tape, ngokuvamile eyaziwa ngokuthi i-golden finger tape, isekelwe kufilimu ye-polyimide, isebenzisa okunamathelayo okungeniswa kwamanye amazwe okuzwela ukucindezela, futhi isebenzisa ifilimu ye-polyimide njenge-substrate. Imbozwe ngohlangothi olulodwa. Ukusebenza okunamathelayo okuzwela ukucindezela kwe-silicone, kunezinhlobo ezimbili zezinto zokwakha, izinto ezikhishwa yi-fluorine zepulasitiki ezinohlangothi olulodwa eziyinhlanganisela noma ezingahlanganisi.

Itheyiphu ye-KAPTON (itheyiphu yokushisa ephezulu ye-polyimide, itheyiphu yokushisa ephezulu yomunwe wegolide) iwuhlobo lokufakwa kwe-insulation ukumelana ne-voltage tape, ehlanganiswe nobukhulu obuhlukahlukene be-polyimide tape (0.04-0.18) ingenziwa ngokwezifiso ngokuya ngezidingo zekhasimende ukumelana nogesi. Ifilimu ye-polyimide ecutshungulwe ngokukhethekile ye-high-temperature resistant insulation material, ene-insulation enhle kakhulu, ukumelana nokugqoka, ukumelana ne-asidi ne-alkali, ukumelana nokushisa okuphezulu kwama-270 degrees / 30 imizuzu, ama-degree angu-180 angasetshenziswa isikhathi eside.

Izinzuzo zetheyiphu ye-polyimide zifingqiwe ikakhulukazi ngamaphuzu amahlanu: ukumelana nokushisa, ukumelana nomswakama, amandla e-dielectric, ukumelana ne-solvent kanye namakhemikhali, kanye nokubumba.

1. Ukumelana nokushisa okuphezulu: amateyipu amabili e-polyimide asongwe ngezingqimba ezimbili eziwugqinsi ongu-0.075mm futhi ambozwe ngepulasitiki ye-F46, lapho izintambo zikazibuthe ezinogqinsi lwe-fluoroplastic ungqimba lwe-0.025mm zisontekile ndawonye, ​​ekushiseni okungu-264°C, Ingafinyelela isikhathi sokuphila samahora angu-20,000, futhi izinga lokushisa elimelana nokushisa lingafinyelela ku-264°C. Njengoba lelizinga lokushisa liseduze nendawo yokuncibilika yongqimba lwe-fluoroplastic, izinga lokushisa eliqinile lingu-240°C kuphela.

2. Ukumelana nomswakama ophezulu: Njengoba ungqimba lwe-insulating lufana futhi alukho amaphinikhodi, ngeke lube lufushane ngaphansi kwezimo zesuphamakethe. Iphinde ibe nokusebenza okuphezulu kwe-insulation ngemuva kokucwiliswa emanzini amahora angama-24.

3. Amandla aphezulu e-dielectric: sebenzisa itheyiphu ye-polyimide engu-0.075mm ewugqinsi enepulasitiki ye-F46, lapho ubukhulu bongqimba lwe-fluoroplastic bungu-0.025mm, u-52% wocingo lukazibuthe ufakwe ungqimba olulodwa, kanti amandla okuphuka angaphezulu kuka-6Kv, okuthi akuthuthuki nje kuphela Izinga le-voltage elimelana phakathi kwamajika liyathuthukiswa, kanye nezinga le-voltage elimelana nalo liyathuthukiswa.

4. Ukumelana okuphezulu kwe-solvent kanye namakhemikhali: Lokhu kunqunywa uhlobo lwe-polyimide tape kanye ne-fluoroplastics, futhi ngenxa yokusebenza kahle kokuvala ungqimba lwe-insulating, umqhubi wethusi ngeke ahlangane nezinto zangaphandle. Ngeke kube khona umonakalo kungqimba oluvikelayo lwentambo enoqweqwe oluqinile yi-solvent ngesikhathi senqubo yokucwilisa evamile.

5. Ukwakheka okuhle: Itheyiphu ye-polyimide enokusebenza okuhle kokunwetshwa ingenza iso le-insulated wire libe yizimo ezihlukahlukene ngaphandle kokuqhekeka nokucekela phansi ungqimba lwe-insulating; ngeke ilimale ngesikhathi sokugoba, ikakhulukazi ikhala eligobile lekhoyili ye-armature conductor. Ukuqhekeka kongqimba lwe-insulation kuzokwenzeka.
