Sebakeng sa tlhahiso ea lipolasetiki, mochini o le mong oa screw extruder o ema joalo ka lipere, o fetola thepa ea polasetiki e tala hore e be lihlahisoa tse ngata tse bopang lefatše la rona la sejoale-joale. Ho tloha ho lipeipi le lisebelisoa ho ea ho liphutheloana le likarolo tsa likoloi, li-scruder tse le 'ngoe ke mokokotlo oa liindasteri tse ngata. Tataiso ena e felletseng e shebana le ho rarahana ha mechini e le 'ngoe ea screw extruder, e lekola melao-motheo ea eona ea ts'ebetso, melemo ea ts'ebetso le lits'ebetso tse fapaneng.
1. Ho Utloisisa Anatomy ea Single Screw Extruder
Bohareng ba screw extruder e le 'ngoe ho na le screw e pota-potileng, karolo ea mantlha e ikarabellang bakeng sa ho tsamaisa le ho fetola thepa ea polasetiki ka mokhoa oa extrusion. Sekoti se behiloe ka har'a barrel, hangata se futhumatsoa ebile se arotsoe ka likarolo ho netefatsa hore polasetiki e qhibiliha le ho tsoakoa.
2. Leeto la Polasetiki ka Single Screw Extruder
Li-granules tsa polasetiki kapa li-pellets li kenngoa ka har'a hopper ea extruder, moo butle-butle li kenngoa karolong ea lijo tsa moqomo. Ha screw e ntse e potoloha, e fetisa thepa ka har'a moqomo, e e beha tlas'a mocheso o ntseng o eketseha le khatello.
3. Ho qhibiliha, ho Kopanya, le Homogenizing Plastic: Matla a Phetoho a Screw
Geometry ea screw le lebelo la ho potoloha li bapala karolo ea bohlokoa ho qhibiliheng, ho kopanya le ho etsa homogenizing polasetiki. Ketso ea ho luba ea screw e senya liketane tsa polymer, ha mocheso o hlahisoang ke likhohlano le mehloli ea ho futhumatsa e ka ntle e qhibilihisa thepa hore e be mokelikeli oa viscous.
4. Ho Bopa Polasetiki ka Liforomo Tse Lakatsehang: Matla a Die
Plastiki e qhibilihisitsoeng e qobelloa ka lefu le entsoeng ka ho khetheha, mohato oa ho qetela oa ts'ebetso ea extrusion. Sebopeho sa lefu se khetholla boemo ba sehlahisoa se fetisitsoeng, ebang ke liphaephe, profiles, sheets kapa lifilimi.
5. Cooling le Solidification: The Final Touches
Ka mor'a ho tsoa ka sekoting, polasetiki e fetisitsoeng e ea pholile ebe e tiisa, ebang ke ka moea, metsi, kapa mekhoa ea ho pholisa ka vacuum. Mohato ona oa ho qetela o netefatsa hore sehlahisoa se boloka sebopeho sa sona se lakatsehang le botšepehi ba sebopeho.
6. Melemo ea Mechini e le 'Ngoe ea Screw Extruder: Ho feto-fetoha ha maemo, ho sebetsa hantle, le ho sebetsa hantle ha litšenyehelo.
Mechini e le 'ngoe ea li-screw extruder e fana ka motsoako o qobellang oa ho feto-fetoha ha maemo, ts'ebetso, le ts'ebeliso e ntle ea litšenyehelo, e e etsa khetho e tsebahalang bakeng sa mefuta e mengata ea likopo tsa tlhahiso ea polasetiki:
Ho feto-fetoha ha maemo: Li-scruders tse le 'ngoe li khona ho sebetsana le lisebelisoa tse ngata tsa thermoplastic, ho kenyelletsa polyethylene, polypropylene, PVC, le ABS.
Katleho: Ts'ebetso e tsoelang pele le moralo o batlang o le bonolo oa li-scruder tse le 'ngoe li kenya letsoho ho sekhahla sa tsona se phahameng sa tlhahiso le ho sebetsa hantle ha matla.
Tšebeliso ea Litšenyehelo: Li-scruders tse le 'ngoe hangata li theko e tlaase ho feta mahlale a mang a extrusion, e leng se etsang hore e be khetho e ntle bakeng sa lits'ebetso tse sa tsotelleng litšenyehelo.
7. Lisebelisoa tse sa tšoaneng tsa Mechini e le 'Ngoe ea Screw Extruder: Lefatše la Lihlahisoa tsa Plastiki
Li-extruder tsa "screw extruder" li fumaneha hohle indastering ea polasetiki, li hlahisa lihlahisoa tse ngata tse amang karolo e 'ngoe le e 'ngoe ea bophelo ba rona:
Liphaephe le Lisebelisoa: Li-scruder tse le 'ngoe ke mokhoa oa mantlha oa ho hlahisa liphaephe tsa polasetiki le lisebelisoa tse sebelisoang lipeiping tsa metsi, tsa kaho le tsa ho nosetsa.
Packaging: Lifilimi tsa ho paka, libotlolo le lijana li entsoe haholo ka li-scruder tse le 'ngoe ka lebaka la ts'ebetso ea tsona le ho feto-fetoha ha tsona.
Profiles: Single screw extruder hlahisa mefuta e mengata ea li-profile tsa polasetiki, ho kenyelletsa le liforeimi tsa lifensetere, liphanele tsa mamati le likarolo tsa kaho.
Lipampiri le Lifilimi: Ho sebelisoa li-scruder tse le 'ngoe ho etsa lipampiri tsa polasetiki le lifilimi bakeng sa lits'ebetso tse kang ho paka lijo, lisebelisoa tsa indasteri le lipontšo.
Likarolo tsa Likoloi: Li-scruder tse le 'ngoe li bapala karolo ea bohlokoa ho etseng likarolo tsa polasetiki bakeng sa likoloi, ho kenyeletsoa li-bumpers, trim ea kahare le likarolo tse ka tlase.
8. Qetello: Mechini e le 'Ngoe ea Screw Extruder - Lejoe la Sekhutlo la Tlhahiso ea Plastiki
Mechini e le 'ngoe ea li-screw extruder e eme e le motheo oa indasteri ea tlhahiso ea polasetiki, ho ikamahanya le maemo, ts'ebetso e ntle, le ts'ebeliso e ntle ea litšenyehelo li e etsa lisebelisoa tsa bohlokoa bakeng sa ho hlahisa lihlahisoa tse ngata tse amang lefatše la rona la sejoale-joale. Ha tlhoko ea lipolasetiki e ntse e hola, li-screw extruder tse le 'ngoe li tla lula li le ka pele ho boqapi, ho khanna tsoelo-pele ho mahlale a lintho tse bonahalang, mahlale a ho sebetsa le mekhoa e tsitsitseng ea tlhahiso.
