Sebakeng sa tlhahiso ea lipolasetiki, metjhini e 'meli ea li-screw pelletizing e eme e le limakatso tsa theknoloji, e fetolang polasetiki e qhibilihisitsoeng hore e be li-pellets tsa junifomo tse sebetsang e le litene tsa ho haha lihlahisoa tse ngata. Ho tloha lifiliming tsa ho paka ho isa ho likarolo tsa koloi, li-twin screw pelletizers ke mokokotlo oa liindasteri tse ngata. Tataiso ena e felletseng e shebana le ho rarahana ha mechini ea twin screw pelletizing, e lekola melao-motheo ea eona ea ts'ebetso, melemo e ikhethang, le lits'ebetso tse fapaneng.
1. Ho Utloisisa Anatomy ea Twin Screw Pelletizer
Bohareng ba "twin screw pelletizer" ho na le li-screw tse pota-potileng, tse hokahaneng ho sebetsa ka tandem. Li-screws tsena li behiloe ka har'a barrel, hangata li arotsoe ka likarolo le ho futhumatsoa ho netefatsa hore polasetiki e ea qhibiliha, e tsoakoa le ho senyeha.
2. Leeto la Polasetiki ka Twin Screw Pelletizer
Plastiki e qhibilihisitsoeng, e atisang ho feptjoa ho tsoa ho extruder e holimo, e kena karolong ea phepelo ea moqomo oa pelletizer. Ha li-screws li ntse li bilika, li fetisa thepa e haufi le moqomo, li e beha tlas'a motsoako o matla, homogenization le khatello.
3. Ho Bopa le ho Seha Plastiki Melt: Matla a Plate ea Die
Plastiki e entsoeng ka ho qhibilihisoa e qobelloa ka poleiti e entsoeng ka ho khetheha, mohato oa ho qetela oa mokhoa oa pelletization. Sebopeho sa "die plate" se etsa qeto ea sebopeho le boholo ba li-pellets, hangata li-cylindrical kapa strand-like.
4. Ho Pholisa le ho Tiisa: Ho Fetola Polasetiki e Khōlō ho ba Lithako
Ka mor'a ho tsoa ka har'a "die plate", li-pellets tse chesang li pholile ka potlako, ebang ke ka moea, metsi, kapa mekhoa ea ho pholisa ka vacuum. Pholiso ena e potlakileng e tiisa li-pellets, ho li thibela ho kopana.
5. Melemo ea Mechini ea Twin Screw Pelletizing: Sebetsa, ho Fetoha, le Boleng ba Sehlahisoa.
Mechini ea Twin screw pelletizing e fana ka motsoako o qobellang oa ts'ebetso, ho feto-fetoha ha maemo, le boleng ba sehlahisoa, e ba etsa khetho e ratoang bakeng sa mefuta e mengata ea likopo tsa tlhahiso ea polasetiki:
Litefiso tse Phahameng tsa Tlhahiso: Li-pelletizers tse peli li ka finyella litekanyetso tse phahameng haholo tsa tlhahiso ha li bapisoa le li-screw pelletizers tse le 'ngoe, e leng se etsang hore e be tse loketseng bakeng sa tlhahiso ea polasetiki e kholo.
Superior Mixing le Homogenization: Li-screws tse pota-potileng li fana ka motsoako o ikhethang le homogenization ea polasetiki e qhibilihisang, e hlahisang li-pellets tse nang le thepa e tsitsitseng le mefokolo e fokotsehileng.
Devolatilization and Venting: Twin screw pelletizers ka katleho e tlosa ho tsitsa le mongobo ho tsoa ho polasetiki e qhibilihang, ho ntlafatsa boleng ba pellet le ts'ebetso e tlase.
Ho Fetolana ka Lisebelisoa tse sa Tšoaneng: Li-pelletizer tse peli tsa screw li khona ho sebetsana le mefuta e mengata ea thepa ea thermoplastic, ho kenyelletsa polyethylene, polypropylene, PVC, le polasetiki ea boenjiniere.
Li-Pellets tsa boleng bo holimo bakeng sa thepa e ntlafetseng ea lihlahisoa: Sebopeho se ts'oanang, boholo, le thepa e tsitsitseng ea polasetiki e entsoeng ka marang-rang e kenya letsoho ho ntlafatseng boleng ba sehlahisoa le ts'ebetsong.
6. Lisebelisoa tse fapaneng tsa Mechini ea Twin Screw Pelletizing: Lefatše la Lihlahisoa tsa Plastiki
Mechini e kopanyang li-screw pelletizing e fumaneha hohle indastering ea polasetiki, e hlahisa li-pellets tseo e leng motheo oa mefuta e mengata ea lihlahisoa:
Lifilimi tsa ho Paka: Lifilimi tsa polasetiki bakeng sa ho paka lijo, lino le thepa ea bareki li entsoe haholo ka polasetiki e entsoeng ka marang-rang.
Liphaephe le Lisebelisoa: Plastiki e entsoeng ka mahlakoreng a mabeli e sebelisoa ha ho etsoa liphaephe le lisebelisoa bakeng sa lipeipi tsa metsi, tsa kaho le tsa ho nosetsa.
Likarolo tsa Likoloi: Li-bumpers, trim ea ka hare, le likarolo tse ling tsa koloi hangata li entsoe ka polasetiki e entsoeng ka marang-rang.
Masela: Lithaele tsa maiketsetso tsa liaparo, lik'hapete le lisebelisoa tsa indasteri li nkiloe ho polasetiki e entsoeng ka mahlakoreng a mabeli.
Lisebelisoa: Likarolo tsa polasetiki tse ka har'a lisebelisoa tsa ka tlung, joalo ka lik'hasete le likarolo tse ka hare, hangata li entsoe ka polasetiki e entsoeng ka marang-rang.
7. Qetello: Mechini ea Twin Screw Pelletizing Machines - Ho khanna Boitlhahiso ho Tlhahiso ea Plastics
Mechini ea "twin screw pelletizing" e fetotse indasteri ea lipolasetiki, ts'ebetso ea eona, ho feto-fetoha ha maemo, le bokhoni ba ho hlahisa li-pellets tsa boleng bo holimo tse li etsang lisebelisoa tsa bohlokoa bakeng sa bahlahisi lefatšeng ka bophara. Ha tlhoko ea lipolasetiki e ntse e hola, li-screw pelletizers tse peli li tla lula li le ka pele ho boqapi, ho nts'etsapele tsoelopele ho mahlale a lintho tse bonahalang, mahlale a ho sebetsa le mekhoa e tsitsitseng ea tlhahiso.
