Imiphongolo yesikulufu esisodwadlala indima ebalulekile ekukhiqizeni amafilimu avuthelwe isikhathi eside. Uchungechunge lwe-JT i-screw barrel eyodwa yokufutha ifilimu kunciphisa izimbobo emikhiqizweni eqediwe ngo-90%, kuthuthukisa kakhulu ukwaneliseka kwamakhasimende. Idizayini yayo ethuthukisiwe iqinisekisa ikhwalithi ephezulu yokuncibilika, iyenze ibe ithuluzi elibalulekile lokuzuza amandla efilimu angaguquki nokunwebeka kuzo zonke izinhlelo zokusebenza. Ukwengeza, ukuhlukahluka kwe-I-PVC Pipe Single Screw Barrelivumela ukusebenza okuthuthukisiwe ezindaweni ezihlukahlukene zokukhiqiza, kuyilapho iumphongolo wesikulufayakhelwe ukuthi ihlangabezane nezidingo zokwenziwa kwefilimu. Sekukonke, uchungechunge lwe-JT imiphongolo yesikulufa eyodwa ibalulekile kubakhiqizi abafuna ukuphakamisa amakhono abo okukhiqiza.
Iqhaza Ledizayini Yemigqomo Yesikulufa Eyodwa Kukhwalithi Ye-Melt
Ikhwalithi Encibilikayo Ikuthinta Kanjani Ukuqina Kwefilimu
Ikhwalithi ye-Melt idlala indima ebalulekile ekunqumeni ukuqina kwamafilimu ashaywa umoya. Ukuncibilika kwekhwalithi ephezulu kuqinisekisa ukusatshalaliswa kwezinto ezifanayo, okuthinta ngokuqondile izici zemishini zefilimu, njengamandla, ukunwebeka, nokumelana nokudabuka. Ngakolunye uhlangothi, izinga lokuncibilika elibi, lingabangela ukushuba okungalingani, izindawo ezibuthakathaka, nokungapheleli kwendawo, okufaka engozini ukusebenza kwefilimu kukonke.
Imiklamo ethuthukisiwe yesikulufu esisodwa, njengaleyo esochungechungeni lwe-JT, ithuthukisa kakhulu ikhwalithi yokuncibilika ngokuthuthukisa inqubo ye-extrusion. Ucwaningo lwakamuva lubonise ukusebenza kahle kokuhlanganisa amamodeli asuselwa ku-physics ukubikezela ukuncibilika kwe-viscosity ku-polymer extrusion. Imiphumela yabonisa ukuthi imodeli ye-CGB izuze amamethrikhi e-RMSE, i-NRMSE, ne-RMSPE ephansi kakhulu, yasebenza kahle kakhulu kunamamodeli ashayelwa idatha. Lokhu kugqamisa ukubaluleka kokulawula okunembile kwe-viscosity encibilikayo, ebalulekile ekukhiqizeni amafilimu ahlala isikhathi eside.
Idizayini yesikulufu sesiteshi nayo inomthelela kwikhwalithi yokuncibilika. Isibonelo, isiteshi esingu-4 mm esisebenza ngesilinganiso sokugunda esingu-109 1/s kanye nesivinini esiyisikulufu esingu-83 rpm siphumela ekulahlekeni okukhulu kwamandla, kuthuthukisa ukuncibilika kwe-homogeneity. Ngokuphambene, isiteshi esingu-8 mm esinezinga eliphansi le-shear engu-35 1/s kanye nesivinini esikulufa esingu-53 rpm sibonisa ukuncishiswa kokuchithwa kwamandla, okungase kuthinte ukufana kokuncibilika. Lokhu okutholakele kugcizelela isidingo semiphongolo yesikulufu eklanywe ngokucophelela ukuze kuzuzwe izimo zokuncibilika ezifanele.
Izici Ezibalulekile Ze-JT Series Single Screw Barrel for Blowing Film
Uchungechunge lwe-JTi-screw barrel eyodwa yokufutha ifilimuihlanganisa izici ezimbalwa ezithuthukile ezithuthukisa ikhwalithi yokuncibilika futhi, ngenxa yalokho, ukuqina kwefilimu.
