Sebakeng se matla sa ts'ebetso ea lipolasetiki, li-conical twin screw extruder (CTSEs) li hlahile e le li-papali-papali, tse fetolang tsela eo li-polymer li kopantsoeng ka eona, li tsoakoang le ho etsoa homogenized. Mechini ena e feto-fetohang e behile maemo a macha bakeng sa ts'ebetso le ts'ebetso e nepahetseng, e sebetsanang le liphephetso tsa lits'ebetso tse hlokang le ho ntšetsa pele indasteri ea polasetiki ho ea meeling e mecha ea boqapi. Poso ena ea blog e shebana le phello ea phetoho ea li-CTSE, ho lekola bokhoni ba tsona bo ikhethang le phetoho ea paradigm eo ba e tlisang ts'ebetsong ea mefuta e fapaneng ea lisebelisoa tsa polasetiki.
Ho Senola Matla a Conical Twin Screw Extruders
Li-CTSE li arolelana melao-motheo ea moralo oa "twin screw extruder" (TSEs), ho sebelisoa likurufu tse peli tse bilikang ho tsamaisa, ho qhibilihisa le ho kopanya lipolymer. Leha ho le joalo, li-CTSE li ikhetholla ka ho kenyelletsa moralo oa conical barrel, moo bophara ba moqomo bo fokotsehang butle ho isa pheletsong ea ho tsoa. Jiometry ena e ikhethang e fana ka melemo e mengata e etsang hore li-CTSE e be khetho e ratoang bakeng sa mefuta e mengata ea likopo tse hlokahalang.
Motsoako o Matlafalitsoeng le Homogenization
The conical barrel geometry e khothalletsa ho kopanya ho matla le homogenization ea motsoako oa polymer, li-additives, le li-filler, ho netefatsa hore ho na le kabo e tšoanang ea thepa nakong eohle ea ho qhibiliha. Bokhoni bona bo holimo ba ho kopanya bo bohlokoa bakeng sa ho hlahisa lihlahisoa tsa boleng bo holimo tse nang le thepa le ts'ebetso e ts'oanang.
Khatello ea Khale e Fokotseng
Phokotso ea butle-butle ea bophara ba moqomo e fokotsa khatello ea moriri ho polymer melt, ho fokotsa ho senyeha ha polymer le ho ntlafatsa boleng ba sehlahisoa. Sena se molemo ka ho khetheha bakeng sa li-polymers tse sa utloeng litsebeng tse atisang ho senyeha tlas'a maemo a phahameng a ho kuta.
Ntlafatso ea Melt Stability
Sebopeho sa conical se matlafatsa botsitso ba ho qhibiliha, ho fokotsa kotsi ea ho qhibiliha ho qhibiliha le ho etsa bonnete ba hore ho na le ts'ebetso e tsitsitseng, e tsitsitseng ea extrusion. Botsitso bona bo bohlokoa bakeng sa ho hlahisa lihlahisoa tsa boleng bo phahameng tse nang le litekanyo tse tšoanang le thepa ea holim'a metsi.
Mefuta-futa ea Likopo tse Batlang
Li-CTSE li ipabola tabeng ea ho sebetsana le metsoako e tlatsitsoeng haholo, li-polymer tse thibelang ho kuta, le metsoako e rarahaneng ea polymer, e leng se etsang hore e be tse loketseng bakeng sa lits'ebetso tse hlokang motsoako o phahameng le boleng ba sehlahisoa. Likopo tsena tse hlokahalang li kenyelletsa:
Khoele le Cable Insulation: Li-CTSE li sebelisoa haholo tlhahisong ea terata e sebetsang hantle haholo le sekontiri sa cable, moo ho kopanya ho tsitsitseng le botsitso ba ho qhibiliha ho leng bohlokoa.
Lipolasetiki tsa Bongaka: Bokhoni ba ho sebetsana le li-polymer tsa boemo ba bongaka bo bobebe bo etsa hore li-CTSE e be tse loketseng hantle bakeng sa ho hlahisa li-tubing tsa bongaka, li-catheters le lisebelisoa tse ling tsa bongaka.
Plastiki ea Likoloi: Li-CTSE li sebelisoa tlhahisong ea lipolasetiki tsa likoloi, ho kenyeletsoa li-bumpers, li-dashboards, le likarolo tsa ka hare tsa trim, moo matla a phahameng le ho tšoarella ho hlokahalang.
Lisebelisoa tsa ho Paka: Li-CTSE li sebelisetsoa ho hlahisa lifilimi le lijana tsa ho paka tse sebetsang hantle, tse hlokang thepa e phahameng ea lithibelo le matla a mochini.
Compounding and Masterbatching: Li-CTSE li ipabola tabeng ea ho kopanya le ho kopanya hantle, moo ho kopanya hantle le ho hasana ha li-additives le li-filler ho leng bohlokoa.
Qetello
Li-conical twin screw extruder li fetotse indasteri ea ho lokisa lipolasetiki, li fana ka bokhoni bo ikhethang bo sebetsanang le liphephetso tsa lits'ebetso tse batloang le ho fana ka boleng bo holimo ba sehlahisoa. Motsoako oa bona o ntlafalitsoeng, khatello ea ho kuta e fokotsehileng, botsitso bo ntlafalitsoeng ba ho qhibiliha, le ho feto-fetoha ha maemo ho etsa hore e be lisebelisoa tsa bohlokoa bakeng sa liindasteri tse fapaneng. Ha tlhoko ea lipolasetiki tse sebetsang hantle haholo e ntse e hola, li-CTSE li mothating oa ho bapala karolo ea bohlokoa haholo ho bopeng bokamoso ba ho sebetsa ka polasetiki, ho khanna boqapi le ho potlakisa indasteri ho ea maemong a macha a bokhabane.
