Li-Twin-Screw Extruders: Li-masters tsa ho kopanya le ho sebetsa ka tlaase-tlaase
Li-extruder tsa Twin-screw li ipabola lits'ebetsong tse hlokang bokhoni bo ikhethang ba ho kopanya le ho sebetsana le sehlahisoa ka bonolo. Li-screws tsa tsona tse kopanyang li hlahisa matla a matla a ho kuta, ka mokhoa o atlehang li hasanya li-additives, li-filler le li-pigments ho pholletsa le matrix a polymer. Bokhoni bona bo holimo ba ho kopanya bo etsa hore li-fahla-screw extruder e be tse loketseng ho sebetsa:
- Lisebelisoa tse thibelang mocheso:Ka lebaka la nako e khuts'oane ea ho lula ka har'a extruder, lisebelisoa tse sa utloeng mocheso ha li na mocheso o fokolang, li boloka thepa ea tsona.
- Lisebelisoa tse sa utloeng bohloko:Li-screws tsa intermeshing li hlahisa sekiri se laoloang, se fokotsa ho senyeha ha sehlahisoa le ho netefatsa boleng bo tsitsitseng.
- Meetso e rarahaneng:Li-extruder tse peli li khona ho sebetsana le libopeho tse rarahaneng tse nang le li-additives tse ngata, li-filler le li-pigments, ho finyella ho hasana ho tšoanang le thepa e tsitsitseng.
Li-Extruders tsa Single-Screw: Bo-'mampoli ba Sebetsa le Litšenyehelo-Ka katleho
Li-extruder tse nang le sekoaelo se le seng, leha li sa tsebe ho tsoaka joalo ka li-fahla-screw, li fana ka melemo mabapi le bokhoni ba tlhahiso, tšebeliso ea matla le litšenyehelo. Moralo oa bona o bonolo le litšenyehelo tse tlase tsa tlhahiso li ba etsa khetho e ntle haholo bakeng sa lits'ebetso tse etelletsang pele:
- Litefiso tse phahameng tsa tlhahiso:Li-extruder tse nang le li-screw tse le 'ngoe li ka fihlella lihlahisoa tse phahameng, tsa etsa hore li tšoanelehe bakeng sa tlhahiso e kholo ea li-profiles tse bonolo le li-tubing.
- Tšebeliso e tlase ea matla:Bakeng sa tlhahiso e fanoeng, li-extruder tsa single-screw ka kakaretso li sebelisa matla a fokolang ha li bapisoa le li-twin-screw extruder.
- Litšenyehelo:Moralo oa bona o bonolo le litšenyehelo tse tlase tsa tlhahiso li etsa hore li-extruder tsa single-screw e be khetho e ntle ea tekanyetso.
Ho Khetha Extruder e nepahetseng: Molao oa ho leka-lekanya
Khetho pakeng tsa "single-screw" le "twin-screw extruder" e itšetlehile ka litlhoko tse khethehileng tsa kopo. Lintlha tse lokelang ho nahanoa li kenyelletsa:
- Lintho tse bonahalang:Lisebelisoa tse thibelang mocheso le ho thibela ho kuta hangata li rua molemo ho li-twin-screw extrusion, ha li-extruder tsa single-screw li loketse lisebelisoa tse sa hlokeng letho.
- Ho rarahana ha sehlahisoa:Metsoako e rarahaneng e nang le li-additives tse ngata e hloka bokhoni bo phahameng ba ho kopanya ba li-twin-screw extruder, ha li-formups tse bonolo li ka sebetsanoa ke li-extruder tsa sekheo se le seng.
- Bophahamo ba tlhahiso:Bakeng sa tlhahiso e phahameng ea li-profiles tse bonolo le li-tubing, li-extruder tsa single-screw li fana ka tharollo e theko e boima.
- Tšebeliso ea matla:Haeba ts'ebeliso e ntle ea matla e le eona ntho e ka sehloohong e amehang, li-extruder tsa single-screw e ka ba khetho e ntle ka lebaka la tšebeliso ea tsona e tlase ea matla.
