Imithelela Ebalulekile ye-PTFE Emulsion Usayizi Wezinhlayiyana Nesisindo Somangqamuzana Ekukhanyeni Kwe-Wear Kwendwangu Ye-Glass Fiber

Indwangu ye-Teflon enezinga lokushisa eliphezulu evela ku-Jiangsu Aokai New Materials iyinhlanganisela esekelwe kwindwangu yengilazi yefayibha, efakwe emulsion ye-polytetrafluoroethylene (PTFE) ne-sintered. Ukumelana kwayo nokugqokwa okuhle kakhulu kubalulekile ekuqinisekiseni impilo ende yesevisi ngaphansi kwezimo zokusebenza ezinamandla njengamabhande okuthutha, ama-gaskets okukhiphayo, nokomiswa kwe-microwave. Izici ezibalulekile ezinquma ukumelana nokugqokwa kwendwangu ye-Teflon enezinga lokushisa eliphezulu zikuzinkomba ezimbili ze-emulsion ye-PTFE ekhulelwe: ukusabalalisa usayizi wezinhlayiyana  nesisindo se-molecular . Lezi zici ezimbili zinquma ngokuqondile ubuqotho, ukufana kanye nokuqina kongqimba oluvikelayo olungaphezulu lwendwangu ye-Teflon ephezulu yokushisa. Ukuze uthuthukise inqubo yokukhiqiza yendwangu ye-Teflon ephezulu yokushisa, kubalulekile ukuqonda imiphumela yabo ebalulekile ekuphikisweni kokugqoka.

Usayizi nokusatshalaliswa kwezinhlayiya ze-emulsion kunquma ukuthi i-PTFE ingakwazi yini ukungena ngokulinganayo futhi ibambelele ngokuqinile ohlakeni lwefayibha yengilazi yendwangu ye-Teflon enezinga eliphezulu lokushisa.

Ibanga elifanelekile likasayizi wezinhlayiyana zendwangu ye-Teflon yezinga lokushisa eliphezulu :Ama-emulsion e-PTFE adizayinelwe ngokukhethekile ukufakwa kwendwangu ye-Teflon yezinga lokushisa eliphezulu ngokuvamile anosayizi wezinhlayiyana omaphakathi olawulwa ku- 0.15–0.35 µm (150–350 nm) . Isibonelo, ama-emulsion akhethekile wendwangu ye-Teflon enezinga eliphezulu lokushisa njenge-Chemours DISP 30LX anosayizi wezinhlayiyana omaphakathi ongu-0.22 µm. Izinhlayiya kulolu hlu zingangena kahle kuzinqwaba zefayibha zendwangu yezinga lokushisa eliphezulu ye-Teflon, zenze isendlalelo sokuvikela esiqinile nesibushelelezi ngemva kokucwiliswa kwamanzi.

Imiphumela emibi yosayizi wezinhlayiyana ezincane kakhulu :I-emulsion ecoleke ngokweqile inokungena ngokweqile. Ngesikhathi sokukhulelwa, kuvame ukungena ngokweqile ku-voids yangemuva noma yangaphakathi ye-substrate, ukunciphisa izingxenye eziphumelelayo zokungagugi ezigcinwe ebusweni bendwangu ye-Teflon ephezulu yokushisa futhi kufinyeze ukuphila kokugqoka okungaphezulu.

Imiphumela emibi yosayizi wezinhlayiyana ezinkulu ngokwedlulele :I-emulsion emaholoholo ngokweqile ayikwazi ukungena ijule ezikhaleni ze-fiber yengilazi yendwangu ye-Teflon eshisa kakhulu, yenze kuphela uqweqwe olungaphezulu oluxegayo. Uma indwangu ye-Teflon enezinga eliphezulu lokushisa ingaphansi kokungqubuzana okuguquguqukayo, le ngubo enamathela kabi ixebuka kalula ibe yizicucu ezinkulu, okuholela ngokuqondile ekuhlulekeni komkhiqizo.

Isisindo sengqamuzana sinquma izici zokulungisa kanye nokuziphatha kwe-tribological ye-polymer ye-PTFE ngokwayo, futhi ibalulekile endleleni yokulwa nokugqokwa kwendwangu ye-Teflon eshisa kakhulu.

Indlela ekwazi ukumelana nokushisa neyokuzithambisa yendwangu ye-Teflon enezinga eliphezulu lokushisa :Ukumelana nokugqokwa kwendwangu ye-Teflon enezinga lokushisa eliphezulu ivela ku-coefficient yayo ephansi kakhulu yokungqubuzana. Ngesikhathi sokungqubuzana, ama-molecule e-PTFE endaweni adlulisele entweni yokukhwelana, akha ifilimu yokudlulisa ezithambisayo evikela indwangu ye-Teflon ngokwayo.

Umthelela ohlukile wesisindo samangqamuzana ekusebenzeni :Ucwaningo lubonisa ukuthi e-Teflon izicelo zendwangu yokushisa okuphezulu, i-PTFE enesisindo esiphansi  ivamise ukubonisa ukumelana nokugqokwa okungcono. Lokhu kungenxa yokuthi i-PTFE enesisindo esiphansi samangqamuzana inamaketanga amafushane wamangqamuzana nokuhamba okuphezulu, okuvumela ukwakheka okusheshayo nokuzinzile kwefilimu yokudlulisa esebenza kahle ngesikhathi sokungqubuzana phakathi kwendwangu nomsebenzi. Ngokuphambene, i-PTFE enesisindo esikhulu samangqamuzana ivame ukudala ukuziphatha kokushelela kwenduku phakathi nokungqubuzana, okungase kubhebhethekise ukugqokwa kwendawo kwendwangu ye-Teflon enezinga lokushisa eliphezulu.

Ukusatshalaliswa kosayizi wezinhlayiya kuqinisekisa ukujula kokungena nokunamathela okufanayo kwentokozo yendwangu ye-Teflon enezinga eliphezulu lokushisa, kuyilapho isisindo samangqamuzana sithuthukisa ukusebenza kahle kwefilimu yokudlulisa ezithambisayo. Kuphela ngokuqonda okujulile nokulawula ngokunembile ubudlelwano phakathi kwalezi zici ezimbili lapho indwangu ye-Teflon yokushisa ephezulu inganikezwa ukusebenza okuvelele kokulwa nokugqoka okudingekayo ukuze kube nezimo zokusebenza eziguquguqukayo zesikhathi eside, ukwandisa ngokuphawulekayo impilo yayo yenkonzo ekubhakeni kokudla, ukomisa ukuphrinta, i-photovoltaic lamination nezinye izinkambu. I-Aokai New Materials igxile kulezi zikhombisi ezincane kakhulu ukuze kuqinisekiswe ukusebenza okuzinzile kwe-macroscopic kwendwangu ye-Teflon enezinga eliphezulu lokushisa.

Ulwazi olungenhla lunikezwe i- Jiangsu Aokai New Materials Technology Co., Ltd.
