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 okomisa, amabhande omshini wokuhlanganisa, nokusonga nge-roller. 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: ukususwa kothuli lwegesi ewuketshezi (usimende, ukushiswa kwemfucuza, amabhayela amalahle afika ku-260°C), ukuhlunga koketshezi 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.

Ama-ejenti wokuqedela ongaphezulu asetshenziswa endwangu ye-fiberglass ngaphambi kokunameka kwe-PTFE abalulekile ekusebenzeni kokugcina kwendwangu yezinga lokushisa eliphezulu ye-PTFE. I-Organosilane coupling agents idala amabhuloho amamolekyuli phakathi kwefayibha yengilazi ye-inorganic kanye ne-organic PTFE, ekhulisa 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.

Iphethini ye-Fiberglass weave - plain, twill, noma satin - ithinta kakhulu izici zendwangu yezinga lokushisa eliphezulu le-PTFE. I-Satin weave inikeza amandla aphezulu okudabula (2-3x plain) nokuguquguquka, ilungele ukugoba okuguquguqukayo. I-Plain weave ihlinzeka ngokuzinza kwe-dimensional okungcono kakhulu kanye nokunamathela kwekhasi, okulungele ukusetshenziswa okumile. I-Twill ibhalansisa zonke izakhiwo ukuze zisetshenziswe ngokujwayelekile.

Ukufana kokunamathela kwendwangu yokushisa ephezulu ye-PTFE kunqunywa izici ezine: ukwakheka kokumboza (usayizi wezinhlayiyana 0.15-0.35 μm, i-viscosity, okuqukethwe okuqinile), inqubo yokugqoka kanye ne-sintering (i-blade coating ekhethwayo ukuze ifane), ikhwalithi ye-substrate (iphethini yokuluka, ukwelashwa kwangaphambili), nendawo yokukhiqiza (20-25% R <60%). I-Dip + blade inqubo ehlanganisiwe ilinganisa ukungena nokushelela kwendawo.

Ukuhlanzwa nokugcinwa ngendlela efanele kwandisa impilo yendwangu ye-PTFE enezinga eliphezulu lokushisa. Hlanza ngemva kokusetshenziswa nangemuva kokupholisa. Sebenzisa amabhulashi athambile, okokuhlanza okungathathi hlangothi, noma utshwala ukuze uthole amabala. Ungalokothi usebenzise ama-asidi/ama-alkali aqinile, i-bleach, noma ama-metal scrapers. Ukugcoba uwoyela we-silicone njalo kunciphisa ukuguga. Landela le mihlahlandlela ukuze ugweme ukulimala kokumboza.

Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu nendwangu ye-silicone kokubili kusebenzisa indwangu ye-fiberglass njengesisekelo kodwa ihlukile ezintweni zokunamathela (i-PTFE resin vs irabha ye-silicone). I-PTFE iphumelela kakhulu ekungabambeni, ukumelana nokugqoka, kanye nokumelana namakhemikhali kufika ku-260°C. Indwangu ye-Silicone inikeza ukuguquguquka okuphakeme, ukufakwa kukagesi, nokumelana nomlilo (kufika ku-230°C). Khetha ngokusekelwe kokubalulekile kwakho.

Indwangu ye-PTFE enezinga eliphezulu lokushisa inikeza ukumelana kwamakhemikhali okukhethekile, imelana nama-asidi aqinile, ama-alkali, izinyibilikisi eziphilayo, namagesi abolayo. Lesi sihloko sichaza ngezinto ezimelana nayo, imikhawulo (izinsimbi ze-alkali ezincibilikisiwe, ama-ejenti anamandla e-fluorinating), nezici ezibalulekile ezifana nezinga lokushisa, ukugxilisa ingqondo, nokucindezeleka komshini.
