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 nokuhambisana ne-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 nesikhathi sokuhlanza.

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.

Ukuminyana kwe-warp ne-weft yendwangu ye-fiberglass inquma ukusebenza kwendwangu ye-PTFE yezinga eliphezulu lokushisa. Ukuminyana okuphezulu kukhulisa amandla okubamba kanye nokushelela kwendawo kodwa kunciphisa amandla okudabuka (ijika le-U elihlanekezelwe), ukuguquguquka, kanye nokungena okunamathelayo. Ukuminyana okuphezulu kulinganisa ukungena, ukumelana nokukhala, ukuguquguquka, nokuqedwa kwendawo. Ukuminyana okuphansi kufanelana nokugoba okuguquguqukayo; high density for non-stick kanye ukwahlukanisa.

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 nokuvumelana nezimo. Ibalulekile ekukhululeni ama-liner kanye nokufakwa kukagesi.

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 ephezulu yokushisa (i-PTFE membrane material) iyinketho ephambili yezakhiwo eziqinile. Izinzuzo eziyinhloko: iminyaka engu-30+ yokuphila kwangaphandle, indawo ezihlanzekile (amanzi emvula ageza ukungcola), ukudlulisa ukukhanya okuthambile (6-13%), isilinganiso somlilo Sekilasi A, namandla afana nensimbi angaphansi kuka-1.5 kg/m². Isetshenziswa ezinkundleni zemidlalo, ezikhumulweni zezindiza, namabhilidi ayisakhiwo sodumo emhlabeni jikelele.

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.
