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.

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 kwamashumi. 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 okomisa, amabhande omshini wokuhlanganisa, nokugoqa kwamarola. Indawo yayo enganamathi ivimbela izinsalela zikayinki/zokunamathela, kunciphisa 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.

Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) ilungele amabhande okuthutha ukudla ngenxa yokumelana nokushisa kwayo okungu-260°C, -70°C ukuguquguquka okubandayo, indawo enganamatheli, kanye nokuthobela kwe-FDA. Izicelo ezibalulekile: ohhavini bebhikawozi (amabhisikidi, isinkwa, i-pizza), izinto zokuthutha ukudla okuthosiwe, izintambo zokupholisa uswidi, imihubhe eqandayo, izinto zokuvala ukushisa, nokugoqwa kwamarola. Yehlisa imfucuza kanye nesikhathi sokuhlanza.

Ama-ejenti wokuqedela ongaphezulu asetshenziswa endwangu ye-fiberglass ngaphambi kokunameka kwe-PTFE abalulekile ekusebenzeni kokugcina kwendwangu yezinga lokushisa eliphezulu ye-PTFE. Ama-ejenti ahlanganisayo e-Organosilane akha amabhuloho amamolekyuli phakathi kwe-inorganic glass fiber kanye ne-organic PTFE, akhulisa amandla ekhasi ukusuka ku-<2 N/cm ukuya ku-4-8+ N/cm. Ukwelashwa okufanele futhi kuthuthukisa ukumelana nokushisa (260°C+), ukusebenza kwe-dielectric, nokumelana namakhemikhali. Indwangu enganakiwe iholela ekuqhekekeni, ekubhibhizeni, nempilo yesevisi emfushane.

I-Calender – ukucindezela indwangu eboshwe nge-PTFE phakathi kwamarola esibuko ashisisayo ku-360-380°C – kushintsha ngokuphawulekayo ukumila kwendawo, ukukhulula izakhiwo, ukungaboli, nokusebenza komshini. Yehlisa ukuhwaqaza ukusuka ku-Ra 0.5-1.0 μm kuya ku-<0.05 μm, ivala amaphinifa, ithuthukise ukumelana nokugqoka, kodwa inciphisa amandla okudabula nokuguquguquka. Ibalulekile ekukhululeni ama-liner kanye nokufakwa kukagesi.
