I-Sintering yisinyathelo esibalulekile lapho izinhlayiya ze-PTFE zincibilika, zigeleze, futhi zihlangane zibe ifilimu eqhubekayo. Kodwa futhi kuyisiteji lapho ukucaba kulahleka kalula khona. Ukushuba okungafani, ukushintsha kwezinga lokushisa okusheshayo, noma ukuzibamba okunganele kungabangela imibimbi engalungiseki, imiphetho enamagagasi, ne-warpage engakwazi ukulungiswa ngemva kwalokho.
Umgomo oyinhloko wokulondoloza ukucaba uwukulawula okunembile phezu kokushuba, izinga lokushisa, nezindlela zokuzibamba - ukunika amandla ukubunjwa okuhlelekile kwe-fiberglass substrate kanye ne-PTFE encibilikisiwe.
I-Aokai PTFE (Indwangu ye-fiberglass ye-PTFE ) ithuthukise izinqubo eziqinile ze-sintering ukuze kuqinisekiswe ukucaba okungaguquki. Lo mhlahlandlela uhlanganisa amaphuzu amahlanu abalulekile okulawula ukucaba okuzinzile ekukhiqizeni ngobuningi.
Ukuvinjwa Kwezisetshenziswa - Umshini We-Stenter Uyimpoqo
Lesi yisixazululo esiyinhloko sokuvimbela ukuncipha kwe-weft kanye nama-wavy selvedges. Iphinikhodi (noma i-clip stenter) kufanele ifakwe ngaphakathi kwesithando somlilo.
1. Ukubumba okuphambene
Amapuleti ophini abhoboza imiphetho yendwangu. Ngokulungisa ububanzi bethrekhi bamaketanga okuthutha, kusetshenziswa ingcindezi encane eguquguqukayo - noma okungenani, ububanzi bendwangu yasekuqaleni buyagcinwa ukuze kulwisane nokucindezeleka kokunciphisa okushisayo kwe-substrate ngaphansi kokushisa okuphezulu. Ngaphandle kwalokhu kuvinjelwa, ububanzi bendwangu buyancipha futhi imiphetho iba amagagasi.
2. Ukulawulwa kwe-longitudinal
Umehluko oqondile wejubane phakathi kwamarola angaphambili nangemuva kanye nokulawula ukushuba kwesimo esivaliwe kuletha ukushuba kwelongi okuphansi kakhulu nokuqhubekayo:
Iphrofayili Yezinga Lokushisa Yesayensi – Ukushisisa I-Gradient kanye Nokupholisa Okunensayo
Ijika legradient lokushisisa okuthambile, ukuncibilika okugcwele, nokupholisa kancane kuyadingeka ukuze kuqedwe ukushaqeka okushisayo kanye ne-warpage ebangelwa ingcindezi.
1. Indawo yokushisa
Izinga lokushisa likhuphuka kancane lizungeze iphoyinti elincibilikayo le-PTFE (327°C) ukuze kulingane izinga lokushisa lendwangu yangaphakathi nengaphezulu. Ukushisa okweqile kwasendaweni noma izinga lokushisa elisheshayo liholela ekuncipheni okungalingani kanye nama-creases angunaphakade. Umgomo uwukuvumela ukushisa kungene ngendlela efanayo ngogqinsi lwendwangu ngaphambi kokuba kuqale ukuncibilika okugcwele.
2. Indawo yokubamba i-Sintering
Izinga lokushisa eliqhubekayo ligcinwa ku- 380-400 ° C isikhathi esanele sokuhlala. Lokhu:
Incibilikisa ngokugcwele izinhlayiya ze-PTFE ibe ifilimu eqhubekayo
Ikhulula ingcindezi yangaphakathi eyinsalela ye-fiberglass ngaphansi kwesimo esiyisicaba esivinjelwe
Iqinisekisa ukuhlanganisa okuphelele nokuminyana
3. Indawo yokupholisa - evame ukunganakwa, kodwa ebucayi
Lesi yisiteji lapho i-warpage evame ukwenzeka khona. Ukupholisa okunensayo kuyadingeka ngenkathi ubamba i-stenter kuze kube yilapho izinga lokushisa lehla ngaphansi kwephoyinti le-PTFE crystallization (cishe 310°C ).
Umthetho obalulekile: Ukupholisa komoya okuphoqelekile ngokushesha kudala ukushwabana okungafani phakathi kokumboza ne-substrate - okuholela ekugoqeni okuqhubekayo noma ama-curling ama-self-curling angeke abe isicaba ngemva kwalokho. Gcina indwangu ivinjelwe kuze kube yilapho i-PTFE isicwebezelise ngokugcwele futhi ikhiyelwe ekumeni kwayo kokugcina.
I-flatness ngesikhathi se-sintering incike kulokho okwenzekayo ngaphambi kokuba indwangu ingene esithandweni somlilo.
1. Ukuncipha kwangaphambili kwendwangu yesisekelo
Ngaphambi kokufakwa kwe-PTFE, indwangu ye-fiberglass idlula i-dewaxing yezinga lokushisa eliphezulu futhi inciphe ngaphambili ukuze isuse ingcindezi esele yokuluka. Lokhu kunciphisa kakhulu ukushwabana kwesibili ngesikhathi se-sintering futhi kubeka isisekelo sokucaba okuphakeme.
Inothi le-Aokai PTFE: Ngaphandle kokuncipha ngaphambili, i-fiberglass izozama ukufinyela ngesikhathi i-sintering - ukulwa nokuvinjelwa okunamandla futhi ibangele ukusabalalisa kokucindezeleka okungalingani.
Isendlalelo esifakiwe se-PTFE kumele sibe nogqinsi olungaguquki kuyo yonke indwangu. Ukwembozwa ngokungalingani kubangela ukuncibilika kwesikhathi okuhlukile - izindawo ezizacile zincibilika ngokushesha kunezindawo eziwugqinsi - okukhiqiza ama-ripples engcindezi afana nokuthungwa kwekhasi lewolintshi futhi konakalise ukucaba.
Ukulawulwa okunembile kokukhulelwa, ukumbozwa kwe-blade kadokotela, kanye nezinqubo zokuminyanisa kubalulekile.
Ngisho nokuhluka okuncane kogqinsi (0.01mm) kungabangela ukukhubazeka okubonakalayo kwendawo.
Amarola Wokuqondisa Ukugeleza Komoya kanye Neziqondiso Ezinembile
1. Umklamo wokujikeleza komoya oshisayo
Yamukela ukushaya okuphikisayo okuphezulu naphansi noma umfaniswano ozungeza umoya oshisayo ngaphakathi kwesithando somlilo ukuze ugweme ukugeleza komoya okunamandla ohlangothini olulodwa ukushaya ngokuqondile indwangu - okubangela izimpawu ze-flutter. Ukusekelwa komcamelo womoya ozinzile kumahhavini avundlile kuvimbela ukuwohloka kwendwangu phezu kweziphali ezinde ezimisiwe.
2. Ukufana okuqinile kwama-roller
Wonke amarola angumhlahlandlela nama-tension roller kufanele agcine ukufana okuphezulu kakhulu futhi ahlale ehlanzekile ngaphandle kwezinsalela ezinamathelayo:
Ukuchezuka kwendwangu encane kuholela ekushubeni kokungalingani ezinhlangothini zombili kanye nemibimbi ehlangene
Kuzofakwa isistimu yokulungisa unqenqema oluzenzakalelayo
Ukuhlanza okuvamile kuvimbela ukunamathela okunamathelayo okudala izinguquko zokungezwani kwendawo
Ukuphaphatheka okuphelele akuzuzwa ngamandla okucindezela angaphandle. Esikhundleni salokho, ngaphansi kokuvinjelwa okuqondile kwepulani yomshini we-stenter, izinga lokushisa elifanayo kanye nokuqina kuyancibilika futhi kuhlanganiswe i-PTFE enamathelayo ne-fiberglass substrate ibe yinhlanganisela ebushelelezi, nakho konke ukucindezeleka okuyinsalela okukhululwa ngokugcwele ngokupholisa kancane kancane.
Ukuchezuka kunoma isiphi isixhumanisi senqubo eyodwa ekugcineni kuzobonakala njengokungalingani kwendawo yendwangu.
