Indwangu ye-PTFE high-temperature (PTFE-coated fiberglass) ingakhiqizwa kusetshenziswa izindlela ezimbili ezihluke kakhulu: ukucwiliswa kwe-single-dip nokucwiliswa okuningi . Ukukhetha phakathi kwabo kunquma ukujiya kwe-coating, ikhwalithi yendawo, izinga lokusebenza, nezindleko.
Enqubweni yokucwiliswa okukodwa, indwangu ye-fiberglass idlula umjikelezo owodwa nje wokucwilisa-wokoma-sintering. Enqubweni yokucwilisa okuningi, ingena emijikelezweni ephindaphindiwe - ngokuvamile engu-2-3 igijima ifike ngaphezu kweshumi nambili - yakha ungqimba lwe-PTFE ngongqimba.
I-Aokai PTFE isebenzisa zombili izinqubo kuye ngohlelo lokusebenza. Lo mhlahlandlela uchaza incazelo, ukugeleza kwenqubo, izici, kanye nokusetshenziswa okujwayelekile kwento ngayinye, kanye nokuqhathanisa kokusebenza okuhlangene kwezinhlangothi.
Inqubo Yokufaka I-Single-Dip Impregnation - Iyashesha futhi Ingabizi
1. Incazelo kanye nokugeleza kwenqubo
Incazelo: Indwangu ye-Fiberglass idlula kumjikelezo owodwa kuphela ophelele we-imregnation-drying-sintering ukukhiqiza indwangu eqediwe ehlanganiswe ne-PTFE.
Ukugeleza kwenqubo:
Indwangu ye-Fiberglass → ukumilisa nge-PTFE dispersion → ukuminyanisa/udokotela-blade ukulawula ukuqoshwa kwe-resin → ukomiswa kwezinga lokushisa eliphansi ukuze kukhishwe amanzi → ukucwiliswa kwezinga lokushisa eliphezulu (360-400°C) ukuze kuncibilike i-PTFE ibe ifilimu eqhubekayo → ukupholisa nokusonga.
2. Izici zenqubo
Ukulandwa kwe-resin kunomkhawulo, kunikeza i-gauge encane, indwangu ye-low-grammage
Ukuthungwa okulukiweyo kwe-fiberglass akukwazi ukugcwaliswa ngokugcwele, okuholela endaweni emagebhugebhu nama-micro-pinholes
Ukumbozwa okungaphelele kwe-PTFE kuholela emandleni aphansi aqinile, amandla e-dielectric, ukumelana nokungena kwamakhemikhali, nokusebenza okungabambeki.
Umjikelezo wokukhiqiza mfushane ngokusebenza kahle okuphezulu kanye eziphansi zezindleko zokukhiqiza nezinzuzo
3. Izinhlelo zokusebenza ezijwayelekile
Indwangu ye-single-dip yamukelwa ezimweni ezinezidingo eziphansi zokushuba, ukungangenisi, kanye nokushelela kwendawo:
Ama-gaskets e-insulating asezingeni eliphansi
Omata besikhashana abanganamathi
Izinto ezivunyeleka kancane ezigcina ukungena komoya ngokwengxenye
Ukusetshenziswa kwezimboni okungabalulekile lapho izindleko zingumshayeli oyinhloko
1. Incazelo kanye nokugeleza kwenqubo
Incazelo: I-fiberglass substrate idlula imijikelezo ephindaphindiwe ye-imregnation-drying-sintering, ngokuvamile esukela ku-2-3 igijima kuze kube ngaphezu kwemijikelezo yeshumi nambili. Isendlalelo ngasinye esilandelayo sifakwe ku-PTFE enamathelayo ukuze kwakhiwe ukujiya, ukugcwalisa izikhala, nokulungisa amaphutha angaphezulu.
Ukugeleza kwenqubo:
Indwangu ye-Fiberglass → Ukufakelwa kokuqala → ukomiswa → ukucwilisa → ukupholisa → ukufakwa kwesibili → ukumisa → ukucwilisa → ukupholisa → Ukufakwa kwesithathu … Ukusongwa kokugcina lapho ukujiya okuhlosiwe, uhlelo lolimi, kanye nokucaciswa kokusebenza sekufinyelelwe.
Ukuhlukahluka kwamasu:
Imijikelezo yokuqala: I-Low-viscosity, ukuhlakazeka okuphezulu kwe-PTFE - ingena ngokugcwele ngaphakathi kwezinqwaba zefiber
Izigaba zakamuva: I-viscosity ephezulu noma i-dispersions yokuqukethwe okuqinile - yakha amafilimu angaphezulu futhi ivale amaphinifa
2. Izici zenqubo
Ubukhulu kanye nokulayisha kwe-PTFE kungalawulwa ngokunembile
Ingxenye ye-PTFE ingafinyelela ku- 50-70% noma ngaphezulu
Ukukhulelwa okuphindaphindiwe kanye ne-sintering kugcwalisa izikhala phakathi kwe-filaments filaments futhi kususe izimbobo, kuletha ukunamathela okubushelelezi, okuhlangene.
Izakhiwo ezinhle kakhulu ezingabambeki nezikhulula
Ukumelana nokugqwala kwamakhemikhali okuvelele nokungangenisi
Amandla e-dielectric athuthuke kakhulu kanye nokumelana nevolumu
Ubuqotho besakhiwo esizinzile nezinga lokushisa lesevisi yesikhathi eside elifinyelela ku-260°C
Ukuhwebelana: Isikhathi sokuhola sokukhiqiza esandisiwe, ukusetshenziswa kwamandla aphezulu, ukulawulwa kwenqubo okuqinile, kanye nezindleko zokukhiqiza eziphakeme.
4. Izinhlelo zokusebenza ezijwayelekile
