Indwangu ye-PTFE enezinga lokushisa eliphezulu ikhiqizwa ngokufakwa kokucwiliswa okukodwa (iphasi eyodwa: esheshayo, eshibhile, enamathelayo emincane, indawo emagebhugebhu enezimbobo zokucwilisa) noma ukucwiliswa kokucwiliswa okuningi (amaphasi angu-2-3+: okubushelelezi, okuminyene, okungenayo iphinifa, okuqukethwe kwe-PTFE 50-70%, ukusebenza kwe-premium, izindleko eziphezulu). I-Single-dip ifanela ama-gasket ebanga eliphansi, omati besikhashana, nezinto eziphefumulayo. I-Multi-dip iyadingeka kumashidi okubhaka ebanga lokudla, amabhande okuthutha angagxili, ama-substrates esekethe yamagagasi aphezulu, amalayini amakhemikhali, nolwelwesi lwezakhiwo.

Indwangu yokushisa ephezulu ye-PTFE enamandla amakhulu iyinhlanganisela ye-high-tenacity fiberglass kanye ne-PTFE coating. Izicelo ezibalulekile zithatha indawo yezimboni (ukubhaka ukudla, ukomiswa kwendwangu, ezokuthutha ze-PCB), ukuvikelwa kwe-welding (amakhava omshini wokushisa ukushisa, izihlangu ze-spatter), ukubhidliza nokwakhiwa kwemishini eshisayo (ukubumba iraba, i-PV lamination), ukufakwa kukagesi (ama-motor slot liners, ukusonga kwekhebula), ulwelwesi lwezakhiwo (uphahla lwenkundla yezemidlalo, iminyaka engu-30+ yokugqwala kwamakhemikhali), ukuphila okuhlangene kwamakhemikhali i-aerospace (izingubo zokulala ezishisayo), kanye nezicelo ezikhethekile (ukusika i-laser, ukuphrinta kwe-3D).

Ukuhlanzeka kwempahla eluhlaza kuyisisekelo sokusebenza kwendwangu yezinga lokushisa eliphezulu le-PTFE. I-emulsion ye-PTFE ye-High-purity (awekho ama-ion ensimbi, awekho izinsalela zesisindo esiphansi) iqinisekisa ukumelana nokushisa (akukho yellowing kufika ku-260°C), okuqinile okungeyona intonga, namandla aphezulu e-dielectric. Ku-fiberglass, i-E-glass engenayo i-alkali (Na₂O <0.8%) igcina amandla nokwahlukanisa emazingeni okushisa aphezulu; ingilazi ephakathi/ ene-alkali ephezulu idala ukuwohloka. Ukususwa ngokuphelele kwama-ejenti wokuluka kuvimbela i-carbonization kanye ne-delamination. Ukuhlanzeka kuthinta ngqo impilo yesevisi, ukuthobela izinga lokudla, nokuthembeka kukagesi.

Impilo yesevisi yendwangu yokushisa ephezulu ye-PTFE iyahluka kakhulu ngohlelo lokusebenza. I-Chemical anti-corrosion lining ingahlala iminyaka engu-3+ (4x ubude kunerabha). Amathreyi okubhaka ukudla ezinyangeni ezedlule anokonakala okuncane. Amabhande e-Industrial conveyor agqoka kusuka ku-friction. I-PV lamination (150°C, EVA contact) inempilo emaphakathi. Izinhlelo zokusebenza zokungqubuzana okukhulu (amadiski abrasive) anokuphila okufushane. Izici ezibalulekile: ukulawulwa kwezinga lokushisa (hlala ku-≤260°C), gwema ama-creases abukhali, ukuhlanzwa okuvamile, nokushintshwa okufika ngesikhathi lapho kunamabhamuza noma kubaphuzi.

Indwangu ye-PTFE ephezulu lokushisa (PTFE-coated fiberglass) ihlala isikhathi eside uma igcinwe ngaphansi kuka-260°C, kude namacrease acijile, futhi ihlanzwa ngamathuluzi athambile. Izici eziyinhloko ezikhawulela ukuphila: ukuwohloka kokushisa okungaphezu kuka-260°C, ukushaqeka okushisayo okuvela ekushiseni ngokushesha/okupholisa, ukukhathala komshini ngenxa yokugoba nokushuba, ukuhlasela kwamakhemikhali okuvela ezinsimbi ezincibilikisiwe ze-alkali noma ama-oxidizers aqinile, umonakalo ovela kuma-metal scrapers ngesikhathi sokuhlanza, kanye nokuchayeka kwe-UV ukuze kusetshenziswe ngaphandle. Ikhwalithi yokugqoka kanye ne-substrate nayo ibalulekile.

Indwangu ye-PTFE yokushisa ephezulu (i-PTFE-coated fiberglass) ilungele ukushisisa i-microwave ngoba ihambisa ama-microwave ngaphandle kokumunca amandla, imelana no-260°C, futhi inendawo engabambeki. Izicelo zihlanganisa omata bokubhaka be-microwave, amabhande omshini wokomisa wemboni, ama-reactor linings okugaya kwamakhemikhali, kanye nama-microwave popcorn bag liners. Amamaki e-FDA atholakalayo ukuze axhumane nokudla.

Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) inokumelana nokugoba okumpofu ngenxa yokuthi i-fiberglass substrate i-brittle ngokwemvelo. Izindwangu ezizacile (0.08mm) zisinda emakhulwini kuya ezinkulungwaneni zokugoqa; amamaki asindayo (>0.25mm) aqhekeka ngemva kwenqwaba. I-Satin weave idlula i-plain weave. Ukuze uthole ukugoba okuqhubekayo, cabangela ifilimu ye-PTFE eqinile noma indwangu esekwe ku-aramid esikhundleni.

Indwangu ye-PTFE yokushisa ephezulu (i-PTFE-coated fiberglass) isetshenziswa kakhulu ekuphrinteni kwendwangu nokudaya amabhande okuphrinta okudlulisa ukushisa (180-230°C), izembozo zetafula lokuphrinta isikrini, amabhande anezikhala omisiwe, amabhande omshini wokuhlanganisa, nokusonga nge-roller. Indawo yayo enganamathi ivimbela insalela ye-inki/ingcina, inciphisa isikhathi sokuhlanza nokuthuthukisa ikhwalithi yendwangu. Amabhande angapheli angenamthungo anika amandla ukukhiqiza okuqhubekayo.

Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) iyisihlungi semidiya ye-premium yezimo ezimbi kakhulu: ukukhishwa kwegesi ye-flue (usimende, ukushiswa kwemfucuza, amabhayela amalahle afika ku-260°C), ukuhlunga uketshezi okugqwalayo (ama-acids, ama-alkali, uwoyela), ukuhlunga ukudla/kwemithi okuyinyumba, nezihlungi zegumbi lokuhlanza i-HEPA. Indawo enganamatheli ivimba uthuli futhi ivumela ukuhlanzwa kalula. Amabanga ane-Membrane-laminated athola ukukhishwa okuphansi kakhulu.

Indwangu ye-PTFE enezinga eliphezulu lokushisa igcina kahle kakhulu ukwahlukanisa kukagesi ukusuka ku- -180°C kuya ku-260°C: ukumelana nevolumu >10¹³ Ω·cm ku-200°C, i-dielectric ihlala iqinile kokuthi 2.0-2.1. Ngaphezulu kuka-260°C, i-PTFE iyathamba, ibole ngaphezu kuka-327°C, ilahlekelwa ukufakwa kwamagciwane unomphela. Ngaphansi kuka-0°C, ukwahlukanisa kuyathuthuka kodwa ukunamathela kuba nzima. Hlala ku-260°C ukuze uthole ukusebenza okuthembekile.
