Okwetheyiphu ye-PTFE yokushisa ephezulu esetshenziswa ezinhlelweni zokungqubuzana kokuslayida okulumayo, okujwayelekile okungeyona induku nokumelana nokushisa akwanele. Imibandela yokukhetha engukhiye: Ukulahleka kwe-Taber abrasion (<15 mg/1000 imijikelezo), imbozwe elungisiwe egcwalisiwe ye-PTFE (i-carbon/graphite/MoS₂), idatha yomkhawulo we-PV, amandla e-substrate (≥200 N/cm), nobulukhuni bokuhlangana (Ra 0.2-0.4 μm). Ukuvikelwa okufanelekile konqenqema nokuhlanganiswa okugcwele kubalulekile ukuze kuphile isikhathi eside.

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 kwe-inorganic glass fiber 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 okudonsa 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-PTFE substrate iyamelana ngokwemvelo nesifutho sikasawoti (ukumuncwa kwamanzi <0.01%). Kodwa-ke, ukusebenza kwe-tape jikelele kuncike ohlotsheni lokunamathela: i-silicone PSA imelana nezindawo zasolwandle (ukuhlolwa kwe-500-1000h ye-salt spray,> 80% ukugcinwa kwekhasi); i-acrylic PSA yehluleka. Ukwelashwa kwendawo efanele, ukusetshenziswa okungenabhamuza, nokuvala onqenqemeni nge-silicone sealant kubalulekile ekuthembekeni kwesikhathi eside ezisekelweni nasezikebheni zasogwini.

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.

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.

Itheyiphu ye-fiberglass ye-PTFE idinga izitifiketi ezintathu ezibalulekile zokuphepha: i-UL (ukuphepha kukagesi nelangabi), i-FDA (ukuthobela ukuxhumana nokudla), kanye ne-ISO 9001:2015 (ukuphathwa kwekhwalithi). Amateyipu aqinisekisiwe anikeza ukusebenza okungaguquki, impilo yesevisi ende, nezindleko eziphelele zobunikazi naphezu kwezindleko eziphezulu zangaphambili. Njalo qinisekisa izitifiketi ngokuqondile nezinhlangano ezikhiphayo.

Amabhande e-PTFE conveyor (amabhande e-Teflon) athuthukisa imigqa yokucubungula ukudla ngezinzuzo ezine ezibalulekile: ukusebenza okuphezulu okungeyona induku (kunciphisa imfucuza nokunamathela), ukubekezelelana kwezinga lokushisa elibanzi (-100°C kuya ku-260°C kwenza ukubhaka kube yiqhwa), ukuhlanza okulula kanye nokumelana namagciwane (indawo engeyona i-porous, i-FDA ehambisanayo, ukusetshenziswa kwamandla okuhlala isikhathi eside), kanye nokusebenzisa amandla okuhlala isikhathi eside). Ifanele izinto ezibhakiwe, ukudla okuqandisiwe, ushokoledi, nemikhiqizo enamathelayo.

Itheyiphu ye-PTFE yokushisa okuphezulu isetshenziswa kuzo zonke izigaba ezintathu zohlelo lokusebenza lwezokwelapha: ukuvikelwa kwemishini yokuvala inzalo (amathreyi e-autoclave, ukupakishwa kwe-heat-seal), ukwelashwa kwendawo yensimbi (i-low-friction coating, insulation kagesi), kanye namadivayisi afakelwayo (ama-vascular grafts, sutures). I-Biocompatibility iqinisekiswa nge-ISO 10993, futhi i-FDA 21 CFR 177.1550 isungula ukuphepha kwezinto eziyisisekelo.

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 enamathela 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.
