Sebakeng sa tlhahiso ea lipolasetiki, li-screw plastic extruder (SSEs) li ema joalo ka lipere, li fetola thepa ea polasetiki e tala hore e be mefuta e fapaneng ea libopeho le lihlahisoa. Mechini ena e feto-fetohang e bapala karolo ea bohlokoa indastering ho tloha ho tsa kaho le ho paka ho isa ho lisebelisoa tsa likoloi le tsa bongaka. Tataiso ena e felletseng e shebana le lefats'e la li-extruder tsa polasetiki tsa screw e le 'ngoe, e lekola melao-motheo ea tsona ea mantlha, lits'ebetso tsa ts'ebetso le ts'ebeliso.
Ho Utloisisa Anatomy ea Single Screw Plastic Extruder
Hopper: Hopper e sebetsa e le mokhoa oa ho fepa, moo li-pellets kapa li-granules tse tala li kenngoa ka har'a extruder.
Feed Throat: 'metso oa phepelo o kopanya hopper le moqomo oa extruder, o laola ho phalla ha thepa ea polasetiki ka har'a screw.
Screw: Pelo ea extruder, screw ke molamu o molelele, oa helical o potolohang ka har'a moqomo, o fetisa le ho qhibilihisa polasetiki.
Barrel: Moqomo, kamore e futhumetseng ea cylindrical, e boloka screw mme e fana ka mocheso o hlokahalang le khatello ea ho qhibiliha ha polasetiki.
Die: E fumaneha qetellong ea barrel, die e bopa polasetiki e qhibilihisitsoeng hore e be sebopeho se lakatsehang, joalo ka liphaephe, li-tubes, kapa maqephe.
Sisteme ea Drive: Sisteme ea drive e matlafatsa ho potoloha ha screw, ho fana ka torque e hlokahalang bakeng sa ts'ebetso ea extrusion.
Cooling System: Mokhoa oa ho pholisa, o atisang ho sebelisa metsi kapa moea, o potlakisa polasetiki e ntšitsoeng ka potlako, e e tiisa hore e be sebopeho se lakatsehang.
Ts'ebetso ea Extrusion: Ho Fetola Plastiki ho Lihlahisoa
Ho fepa: Li-pellets tsa polasetiki li fepeloa ka har'a hopper le matla a khoheli a feptjoa 'metsong oa phepelo.
Conveying: The rotating Screw e fetisa li-pellets tsa polasetiki haufi le barrel, li li tsamaisa ho ea moo.
Ho qhibiliha: Ha li-pellets tsa polasetiki li ntse li tsamaea haufi le screw, li kenngoa ke mocheso o hlahisoang ke barrel le khohlano e tsoang ho screw, e etsang hore li qhibilihe ebe li etsa phallo ea viscous.
Homogenization: Ketso ea ho qhibiliha le ho tsoaka ha screw homogenize polasetiki e qhibilihisitsoeng, ho netefatsa ho ts'oara ho ts'oanang le ho tlosa lipokotho tsa moea.
Pressurization: Sekoti se hatella le ho feta polasetiki e qhibilihisitsoeng, se hlahisa khatello e hlokahalang ho e qobella ka thipa.
Shaping: Polasitiki e qhibidihileng e qobelleha ka lesoba la difase, e nka sebopeho sa sebopeho sa die.
Ho pholisa: Polasetiki e pharalletseng e pholile hang-hang ke sistimi e pholileng, e e tiisa hore e be sebopeho le sebopeho se lakatsehang.
Lisebelisoa tsa Single Screw Plastic Extruders: Lefatše la Menyetla
Pipe le Profile Extrusion: Li-SSE li sebelisoa haholo ho hlahisa liphaephe, li-tubes, le li-profile bakeng sa lisebelisoa tse fapaneng, ho kenyelletsa le li-plumbing, tsa kaho le liindasteri tsa likoloi.
Filimi le Maqephe a Extrusion: Lifilimi tse tšesaane tsa polasetiki le maqephe li etsoa ho sebelisoa li-SSE, 'me li sebelisoa ka har'a liphutheloana, temo le lisebelisoa tsa bongaka.
Fiber le Cable Extrusion: Li-SSE li bapala karolo ea bohlokoa tlhahisong ea likhoele tsa maiketsetso tsa masela, liropo le likhoele.
Ho Kopanya le ho Kopanya: Li-SSE li ka sebelisoa ho kopanya le ho kopanya lisebelisoa tse fapaneng tsa polasetiki, ho theha libopeho tse tloaelehileng tse nang le thepa e itseng.
Qetello
Li-extruder tsa polasetiki tsa screw tse le 'ngoe li eme e le lisebelisoa tsa bohlokoa indastering ea ho etsa lipolasetiki, ho feto-fetoha ha tsona le bokhoni ba tsona bo nolofalletsang tlhahiso ea mefuta e mengata ea lihlahisoa tse amang lefatše la rona la sejoale-joale. Ho tloha ho liphaephe le liphutheloana ho ea ho likhoele le lisebelisoa tsa bongaka, li-SSE li bohareng ba ho fetola thepa ea polasetiki e tala hore e be lihlahisoa tse bonahalang tse ntlafatsang bophelo ba rona. Ho utloisisa melao-motheo le ts'ebeliso ea mechini ena e tsotehang e fana ka leseli la bohlokoa lefats'eng la tlhahiso ea polasetiki le matla a phetoho a boenjiniere.
