Indwangu ye-fiberglass enwetshiwe (indwangu yomucu oyinqwaba) ihluke kakhulu kundwangu evamile ye-fiberglass esakhiweni sentambo. Ngokwelashwa kwejethi lomoya elinengcindezi ephezulu, imicu yengilazi eqhubekayo iyahlukaniswa, iboshelwe, futhi ifakwe emculweni ogqamile, ofana nokotini. Lokhu kudala indwangu ewugqinsi, ethambile enokwahlukanisa okushisayo okuphakeme (izingqimba zomoya ezivaleleke), ukuvumelana kangcono, ukusebenza kahle kokuhlunga okuphezulu, nokumelana okuthuthukisiwe kwezinyembezi/okuguquguqukayo - ngezindleko zamandla okubamba kancane kancane. Isetshenziselwa ama-gaskets ashisa kakhulu, amapayipi asongayo, izikhwama zokuhlunga, nama-oven seal.

Indwangu ye-PTFE ephezulu lokushisa (i-PTFE-coated fiberglass) icishe ifane namakhemikhali, kodwa izinto ezithile zibanga ukugqwala ngaphansi kwezimo ezithile. Ukuhlasela okuqondile kwe-PTFE kwenzeka ngezinsimbi ze-alkali ezincibilikisiwe (i-sodium, i-potassium), i-fluorinating agents eqinile (F₂, ClF₃) emazingeni okushisa aphezulu, kanye nama-alkali aqinile ancibilikisiwe ngaphezu kuka-300°C. Ukugqwala okungaqondile kwenzeka lapho i-hydrofluoric acid (HF), i-alkali egxilile eshisayo, noma i-hot phosphoric acid ingena ezinkingeni zokumboza bese ihlasela i-fiberglass substrate. Ukuze uthole isevisi yamakhemikhali eyeqisayo, sebenzisa ifilimu ye-PTFE ehlanzekile ngaphandle kwe-fiberglass.

Indwangu ye-PTFE ephezulu yokushisa (i-PTFE-coated fiberglass) inokumelana nokushaqeka okuhle kakhulu okushisayo ngaphakathi kwebanga lokusebenza elijwayelekile elingu -70°C kuya ku-260°C. Ingakwazi ukubekezelela ukuhamba ngebhayisikili okusheshayo kwezinga lokushisa, isb, ukusuka ku- -50°C efrijini ukuya emshinini wokunyathelisa oshisayo ongu-260°C. Amabanga e-Premium aze asinde ekupholiseni kungazelelwe ukusuka ku-260°C ukuya ku-10°C emanzini. Nokho, ukushaqisa okokusebenza emazingeni okushisa angaphezu kuka-300°C (eduze kwendawo yokuncibilika ye-PTFE's 327°C) kuzodala ukuqhekeka kanye nokuncibilika ngokushesha. I-fiberglass substrate inikeza ukuzinza kwe-dimensional; ukunamathela kwe-PTFE kuyisici esikhawulelayo.

Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu isetshenziswa kabanzi embonini yamakhemikhali ezintweni eziyisikhombisa ezibalulekile: ama-flange gaskets namapayipi afakwa ngaphakathi (amelana nama-acids aqinile/ama-alkali), i-reactor kanye ne-tank linings (ivimbela ukugqwala kwensimbi, ukuhlanzeka kalula), izikhwama zokuhlunga zegesi egqwalayo (efika ku-260°C), ukunwetshwa kokubola kwe-corrosion, ukunwetshwa kokukhishwa kwendwangu yensimbi ukubumba okuyinhlanganisela, kanye nokusonga kokufakwa kukagesi/okushisayo. I-FDA ne-UL amamaki ayatholakala.

Indwangu ye-PTFE yokushisa ephezulu (PTFE-coated fiberglass) inikeza izinzuzo ezine ezibalulekile njenge-anti-corrosion lining: ukunganaki kwamakhemikhali (kumelana ne-aqua regia, ama-alkali aqinile, izinyibilikisi), ububanzi bokushisa (-70 ° C kuya ku-260 ° C ngokuqhubekayo, ukuphakama okungu-350 ° C), ukuzinza kwe-dimensional (<0.5% ukuqina), ukuhlanza ubuso obunzima, ukuvimbela ukuqina). Isetshenziswa kumapayipi amakhemikhali, imibhoshongo ye-desulfurization, amathangi okukhetha, kanye nempahla yokudla/ekhemisi. Amabanga e-FDA ayatholakala.

Indwangu ye-PTFE enezinga eliphezulu lokushisa inikeza izinzuzo eziyisithupha ezibalulekile njengebhande lokuthutha eliphrintayo: indawo engeyona induku (okunamathiselwe kokuphrinta nokukhishwa kukayinki ngokuhlanzekile), ukumelana nokushisa okungu-260°C (ukoma okusebenzayo), ukuzinza kwe-dimensional (<0.5% ubude, ukubhaliswa okunembile), ukungabi namandla kwamakhemikhali (imelana nokunamathisela okubolayo), ukungqubuzana kombala okuphansi, ukungqubuzana kombala ophansi, ukungqubuzana kombala, kanye nokusebenza okuqinile I-antistatic). Ilungele ukuphrinta isikrini, ukuphrinta kwedijithali, nezinhlelo zokusebenza zokudlulisa ukushisa.

Indwangu ye-PTFE ye-Anti-static izinga lokushisa eliphezulu ihlanganisa okunganamatheli, ukumelana nokushisa (260°C), kanye nezakhiwo ezingasebenzi ngamakhemikhali ze-PTFE ezijwayelekile nokusebenza kwe-static-dissipative. Izicelo ezibalulekile: ukukhiqizwa kwe-elekthronikhi (i-PCB lamination, ukuphathwa kwengxenye), i-PV module lamination (ivimbela ukulimala kwe-ESD kumaseli elanga), ukucubungula ukudla kanye nemithi (i-ESD-safe baking liners), izitshalo zamakhemikhali (anti-corrosion, anti-static ducting), kanye nezimboni zendwangu / zokunyathelisa. Ukumelana nobuso ngokuvamile 10⁶–10⁹ Ω.

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 enezinga eliphezulu lokushisa izinzile kufika ku-300°C, kodwa emlilweni iyabola futhi ikhiphe amagesi anobuthi obukhulu: i-hydrogen fluoride (HF) (i-corrosive, pulmonary edema) ne-perfluoroisobutylene (PFIB) (ayinambala, ayinaphunga, ~10x ubuthi obungaphezu kwe-phosgene, i-nodo). Futhi i-carbon monoxide, izinsalela ze-PFOA, kanye ne-trace dioxins. Izifihla-buso zentuthu ezivamile azisebenzi; sebenzisa izisetshenziswa zokuphefumula ezizimele (SCBA). Izimpawu zingase zibambezeleke.

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.
