Ngokuthuthukiswa komphakathi kanye nokufunwa komuntu okwandayo komuntu, ipulasitiki sekuyinto ebaluleke kakhulu empilweni yabantu. Eminyakeni yamuva nje, ngohlelo lokusebenza olubanzi lwemikhiqizo yepulasitiki nokukhula okusheshayo kokuphuma, isidingo semishini yepulasitiki sekwanda futhi kancane kancane sibe ngomunye wezimboni ezikhula ngokushesha kakhulu. Ngokusho kwezibalo, ngaphezu kwama-60% wemikhiqizo yepulasitiki ecutshungulwa ngokukhishwa, futhi ukukhishwa sekuyindlela ebalulekile yokucubungula kwezinto ze-polymer. Ngakho-ke, ipulasitiki extruderhas yathuthukiswa ngokushesha, futhi isetshenziswe kabanzi ngokwengeziwe ngenxa yokusebenza kwayo okuhle kakhulu.
Nalu uhlu lokuqukethwe:
Kuyini ukugeleza kwenqubo yokukhishwa kwepulasitiki?
Yiziphi izindlela zokuthuthuka ze-plastic extuders?
Kuyini ukugeleza kwenqubo yokukhishwa kwepulasitiki?
Izinhlobo eziningi zepulasitiki zingacutshungulwa ngokubumba kokukhishwa, futhi imikhiqizo ihlukahlukene kakhulu. Kunokwehluka okuningi kwinqubo yokubumba, kepha ukugeleza okuyisisekelo kwenqubo kufana.
Inqubo evamile yokondla kanye nemikhiqizo eyengeziwe ku-SOLICAL-STATE ukwengeza izinto ze-granular noma ze-popper ku-hopper yomshini ongezelelesi wepulasitiki, kanye ne-heater kancane kancane inyusa izinga lokushisa lezinto zokwakha. Ngokudluliselwa kwesikulufa, izinto zokwakha zithuthwa phambili. Ngesikhathi senqubo yokuhamba, izinto zokwakha zihlikihla bese zigunda ngodonga lwe-barrel, isikulufa, nezinto eziningi, okuholela ekushiseni okuningi. Izinga lokushisa lizoqhubeka nokukhuphuka, okungenza ukuthi izinto zokwakha zincibilike ngokuqhubekayo. Izinto ezincibilikisiwe ziyaqhubeka ziqhubeka nokuhanjiswa ekhanda ngesimo esinqunyelwe. Ngemuva kokudlula ekhanda, okuqukethwe esimweni se-fluid kufinyelela esimweni esifana nesimo somlomo. Ngaphansi kwesenzo sedivaysi ye-traction, umkhiqizo ungaqhubekela phambili ngokuqhubekayo futhi uthole usayizi womkhiqizo wokugcina. Ekugcineni, nquma imikhiqizo ngokusika ukugcinwa nokuhamba.
Yiziphi izindlela zokuthuthuka ze-plastic extuders?
Kunezindlela ezinhlanu zokuthuthuka zepulasitiki ye-pellet extret.
1. Ijubane eliphakeme kanye nesivuno esikhulu
Ijubane eliphezulu ne-extred evundile ephezulu lingavumela abatshalizimali ukuthi bathole imiphumela emikhulu kanye nokubuyiselwa okuphezulu ngokutshalwa kwemali okuphansi. Kepha ngasikhathi sinye, ijubane eliphakeme lejubane le-extruder screw futhi liletha uchungechunge lobunzima okufanele lunqotshwe, okuyizinkinga eziphuthumayo ezizoxazululwa ekuthuthukisweni okuzayo.
2. Isebenza kahle futhi iyasebenza
Ukusebenza okuphezulu kwe-extruder yepulasitiki kuboniswa ikakhulukazi ekuphumeni okuphezulu, ukusetshenziswa kwamandla okuphansi, kanye nezindleko zokwenziwa okuphansi. Ngokuya komsebenzi, i-screw extruder ayikasetshenziselwa nje kuphela ukukhishwa nezinqubo zokuxubha zezinto ezisetshenziswayo ze-polymer, kepha futhi kuye kwandise nezinkambu ezahlukahlukene njengokudla, okuphakelayo, i-electrode, ukuqhuma, ukupakisha, nokupakisha, nokupakisha nokunye.
3. Isikali esikhulu nokunemba
Ukubona imishini yokukhishwa okuphezulu kakhulu kunganciphisa izindleko zokukhiqiza, ngenkathi ukunemba kungathuthukisa okuqukethwe kwegolide kwemikhiqizo. Isibonelo, amafilimu ahlanganisiwe ahlukahlukene ahlukahlukene ahlukahlukene adinga ukukhishwa kwengqondo. Kumele siqinise ukuthuthukiswa kanye nocwaningo lwamaphampu we-Melt Gear, okuyindlela ebalulekile yokuthola ukucaciswa kwengqondo.
4. I-modularization kanye nobungcweti
Ukukhiqizwa kwesimonhlobo kungahlangabezana nezidingo ezikhethekile zabasebenzisi abahlukile, finyeza umjikelezo we-R & D wemikhiqizo emisha bese ulwela isabelo esikhulu semakethe; Ukukhiqizwa okukhethekile kungahlela ukukhiqizwa kwephuzu elihleliwe noma ukutholakala kwempahla yemodyuli ngayinye yemodyuli yemodyuli ye-modul design, okuzuzisa kakhulu ukuqinisekisa yonke ikhwalithi yesikhathi, ukunciphisa izindleko ezinkulu.
5. Ukuqonda kanye Nezindawo Zokuxhumana
Ubuchwepheshe banamuhla bezobuchwepheshe be-elekthronikhi nekhompyutha busetshenziswe kabanzi ku-extuders emazweni athuthukile ukuthola amapharamitha enqubo wenqubo yonke yokukhishwa yonke online futhi amukele ukulawulwa kwe-microcomputer. Lokhu kuzuzisa kakhulu ukuqinisekisa ukuqina kwezimo zenqubo futhi kuthuthukise ukunemba kwemikhiqizo.
Eminyakeni yamuva nje, inqubekela phambili enkulu yenziwe kusethi ephelele yemishini yepulasitiki eChina. Isibonelo, iyunithi yokukhishwa kwepulasitiki ifinyelele ezingeni elifanelekile, imininingwane yamayunithi ahlukahlukene amaphayipha aya ngokuya iphelele, futhi izinga lomkhiqizo nekhwalithi athuthukiswa ngokuqhubekayo. I-Suzhou PolyTime Machchmime Co, Ltd izibophezele ekwakheni imishini yokukhiqizwa kwepulasitiki yokuqala ngekhwalithi yayo impilo, isayensi, nobuchwepheshe njengokutholwa kwayo okuholela nokweneliseka kwamakhasimende njengenhloso yayo ehamba phambili neyomakhasimende njengenhloso yayo. Uma unezidingo ezifanele noma inhloso yokubambisana, ungakhetha imikhiqizo yethu ethunyelwa kuwo wonke umhlaba.
