Indwangu ye-PTFE ye-Anti-static ifinyelelwa ngezindlela ezimbili eziyinhloko: ukumboza i-doping (ukuxuba izigcwalisi ze-conductive ezifana ne-carbon black zibe i-PTFE emulsion, ukwakha inethiwekhi ye-percolation ekugxiliseni okubucayi) kanye nokwelukwa kwe-substrate (ukushumeka imicu yokuqhuba ibe yindwangu ye-fiberglass). Ukumelana nobuso kulawulwa kokuthi 10⁵–10⁹ Ω. Umgomo: dala indlela yokuqondisa edonsa amashaji amile ngokushesha, ivimbele ukunqwabelana okuyingozi. Ukugawula kuyadingeka ukuze kusebenze ngempumelelo.

Ama-thickeners ku-emulsion ye-PTFE enza imisebenzi emine ebalulekile: ukumiswa kokumiswa (kuvimbela ukuhlaliswa kwezinhlayiya eziminyene ze-PTFE), ukuziphatha kwe-shear-thinning (i-viscosity ephezulu ekuphumuleni, ephansi ngaphansi kokuyaluza ukuze kuhlanganiswe kalula), ukulawula ukujula kokungena (ukulawula ukulayishwa kwe-resin endwangu ye-fiberglass), kanye nokufana kwefilimu (kuvimbela ukuqhekeka ngesikhathi somiswa). Isidingo esibalulekile: izingqimba kufanele zibole ngokuphelele ku-~380°C izinga lokushisa le-sintering, lishiye i-zero umlotha insalela ukuze kugcinwe ukuhlanzeka kokunamathela kanye nokufakwa kukagesi.

Indwangu ye-PTFE esezingeni lokushisa eliphezulu (i-PTFE-coated fiberglass) inikeza ukumelana kwamakhemikhali okuhlukile, ukumelana nama-acids agxilile (okuhlanganisa i-aqua regia), ama-alkali aqinile (ezingeni lokushisa lasekamelweni), izinyibilikisi eziphilayo, nama-oxidizing agents. Okuhlukile: izinsimbi ze-alkali ezincibilikisiwe nezinhlanganisela ze-halogen ezisezingeni eliphezulu zihlasela i-PTFE. Ukulimala kwe-coating kuveza i-fiberglass ku-hydrofluoric acid nama-alkali agxilile ashisayo. Izinga lokushisa elingaphezu kuka-260°C linciphisa ukumelana. Ezimweni eziningi zamakhemikhali, indwangu ye-PTFE ihlala izinzile futhi ithembekile.

Itheyiphu ye-PTFE yobubanzi obubanzi bezinga lokushisa idinga i-silicone PSA egcina ukunamathela ukusuka -70°C kuya ku-260°C. Izakhi eziyinhloko zokuklama: ungqimba lwenguquko olunama-primer-anchored (lugwema i-delamination), i-sea-island microstructure (i-MQ resin Islands + i-polysiloxane isigaba esiqhubekayo), i-gradient crosslinking (ungqimba olungaphakathi olunomthamo omkhulu wokumelana nokukhasa, ungqimba lwangaphandle olunobukhulu obuphansi bokudonswa kwezinga lokushisa eliphansi), kanye nezigcwali ezizinzile ze-oxid oxide (i-oxid oxide). Amasegimenti e-phenyl-modified siloxane acindezela i-crystallization yezinga lokushisa eliphansi, evumela ukuguquguquka okungaphansi -100°C.

I-Aokai PTFE ikhiphe okokuqala ngohlelo lwayo oluphelele lomkhiqizo e-APFE Shanghai 2026 (Booth 6T602, Hall 6). Imikhiqizo efakiwe ihlanganisa amateyipu e-PTFE aqiniswe nge-fiberglass, amafilimu e-PTFE ahlanzekile, amamaki aphikisana ne-static, namabhande okuthutha asezingeni eliphezulu - amboza ukucubungula ukudla, i-PV lamination, amabhethri e-lithium, izinto zikagesi, nokupakishwa. Umbukiso uqhubeka kuze kube uJuni 26. Yonke imikhiqizo isekela ukucaciswa okungokwezifiso.

Indwangu yokushisa ephezulu ye-PTFE enamandla amakhulu iyinhlanganisela ye-high-tenacity fiberglass kanye ne-PTFE coating. Izicelo ezibalulekile zithatha indawo yezimboni (ukubhaka ukudla, ukomiswa kwendwangu, ezokuthutha ze-PCB), ukuvikelwa kwe-welding (amakhava omshini wokushisa ukushisa, izihlangu ze-spatter), ukubhidliza nokwakhiwa kwemishini eshisayo (ukubumba iraba, i-PV lamination), ukufakwa kukagesi (ama-motor slot liners, ukusonga kwekhebula), ulwelwesi lwezakhiwo (uphahla lwenkundla yezemidlalo, iminyaka engu-30+ yokugqwala kwamakhemikhali), ukuphila okuhlangene kwamakhemikhali i-aerospace (izingubo zokulala ezishisayo), kanye nezicelo ezikhethekile (ukusika i-laser, ukuphrinta kwe-3D).

Ukomisa kuyisinyathelo esibalulekile ekukhiqizweni kwendwangu yezinga lokushisa eliphezulu ye-PTFE. Amaphutha avamile ahlanganisa: ukuqhekeka (ukoma ngokushesha okukhulu, ukucwiliswa kwesikhumba), ukuguquguquka kokumboza (izinhlayiya zithuthela phezulu, isibopho sangaphakathi esibuthakathaka), izimbobo/amabhamuza (umoya ovaleleke noma isitimu), amabala amhlophe kanye nokushova (ukufuduka kwe-surfactant noma ukuhlangana okungaphelele), ukuphuzi/ukupheka (ukushisa ngokweqile kwezithasiselo), i-delamination (i-deposion noma izinga le-orange) ukushwabana), indawo yomile kodwa ingaphakathi imanzi (isikhumba sibamba umswakama), kanye nemiphetho ewugqinsi (umphumela wendandatho yekhofi). Izixazululo zibandakanya amaphrofayili okomisa okulawulwayo, ukungena komoya ngendlela efanele, nokwelashwa kwangaphambili kwe-substrate.

Isakhiwo sobuso esisikiwe se-PTFE itheyiphu yokushisa okuphezulu sithinta ngokuqondile ukunamathela okunamathelayo nokuphakamisa unqenqema ngesikhathi sokufaka isicelo. Ukusika okungalungile (izindwani ezibuthuntu, i-engeli engafanele) kudala imicu yeglue, kwenze kube mncane ungqimba olunamathelayo olusemaphethelweni, futhi kuveza obala ama-fiberglass burrs - okuholela ekuphumeni, ekuhlanganisweni okubuthakathaka, nasekuphakamiseni ngaphansi kokushisa noma ukushuba. Ubuso obungajwayelekile bokuphela (okunamagagasi, obuphumela ngaphandle) bubangela ukusakazwa kwengcindezi engalingani, ukushayela okunamathelayo kukhase ngesikhathi sokulondoloza. Ubuso obufanele ekugcineni bushelelezi, buyashesha, futhi abunamonakalo - busebenza njengesivalo esikhiya okunamathelayo futhi siqinisekise ukubopha okugcwele emaphethelweni.

I-PTFE emulsion impregnation yendwangu ye-fiberglass idinga abasizi abahlukahlukene ukuze kuzuzwe ukunamathela okufanayo, ukunamathela okuqinile, kanye nezindawo ezingenasici. Izithasiselo ezibalulekile zifaka: ama-ejenti okumanzisa (ehlisa ukushuba kwesimo, athuthukise ukungena), izingqimba (ukulawula i-viscosity nesisindo sokunamathela), izilawuli ze-pH (zinza i-emulsion ku-pH 9-10), ama-silane coupling agents (athuthukisa ukunamathela engilazini), izinsiza zokwakha ifilimu (PFA/FEP ye-sintering), izigcwalisi ezisebenzayo (ukumelana nokuguga), ama-pifonholes (ukoma kancane). Ukukhethwa kuncike ku-substrate nezidingo zokusebenza.

Ngesikhathi sokumbozwa kwetheyiphu ye-PTFE, izinga le-solvent volatilization ye-adhesive ezwela ukucindezela kwe-silicone iyipharamitha yenqubo ebalulekile. Kushesha kakhulu → ukuhlikihlwa kwesikhumba, ukungaleveli kahle, amaphinifa (i-solvent evalelekile), nama-craters (ukujiya noma okubangelwa ukungcola). Iyanensa kakhulu → ukuwohloka, imiphetho ewugqinsi, kanye nokumanzisa ku-PTFE yamandla aphansi. Isu elilungile: ukuvuthwa kancane kwasekuqaleni kokulinganisa nokuphunyuka kwebhamuza, bese kusheshiswa ukomiswa ukuze kubunjwe. Sebenzisa izincibilikisi ezixubile (i-toluene/xylene + ukomisa ngokushesha) nezinga lokushisa likahhavini we-gradient (eliphansi→elimaphakathi→phezulu).
