Plastic extruder ke karolo ea mantlha le ea mantlha ea mefuta eohle ea mechini ea polasetiki. Ho na le mefuta e mengata e fapaneng ea li-extruder tsa polasetiki tse kang single screw extruder, twin screw extruder, multi-screw extruder. Mochini oa extruder oa polasetiki o sebelisoa bakeng sa extrusion ea phala ea polasetiki, extrusion ea profil ea polasetiki, extrusion ea boto ea polasetiki, ente ea polasetiki, granulating ea polasetiki .....
Plastic Extrusion ke Eng?
Ka mantsoe a bonolo, extrusion ea polasetiki ke "mokhoa oa ho etsa lihlahisoa tse phahameng" moo polasetiki e tala e qhibilihisitsoeng ebe e etsoa hore e be profil e tsoelang pele. Mechini ea extrusion ea polasetiki e thusa ho potlakisa phallo ea mosebetsi le molumo. E ntle bakeng sa ho netefatsa lihlahisoa tse lumellanang.
Mokhoa oa Extrusion o sebetsa Joang?
Ts'ebetso ea Extrusion - lisebelisoa tsa polasetiki tse tala lia kena, sehlahisoa sa extrusion sea tsoa, se lekanngoa, se pholile ebe se khaola ka boholo. Ka tlase ke likarolo tsa li-extruder:
· Screw Design
Ha thepa e ntse e feptjoa pheletsong e le 'ngoe ea polasetiki ea extruder (hopper), butle-butle e qhibilihisoa ke mocheso le matla a hlahisoang ke li-screw. Li-screws tsena li haufi le moqomo oa mochini moo lisebelisoa tse tala li qhibilihang. Mefuta e mengata ea li-screws e na le libaka tse tharo tse fapaneng ho tsamaisana le ts'ebetso ea extrusion:
- Sebaka sa Phepelo: Mona ke moo thepa e kopantsoeng ea polasetiki e feptjoang mochining oa extrusion.
- Melting Zone: Karolo e latelang ea moralo oa screw ke moo polasetiki e qhibilihang.
- Metering Zone: Qetellong, sebaka sa metering ke moo likotoana tsa ho qetela tsa polasetiki li qhibilihang ebe li tsoakoa ho theha mocheso o ts'oanang le sebopeho.
· Taolo ea Mocheso
Ho etsa bonnete ba hore lisebelisoa tsa ho qetela li ke ke tsa nyenyefatsa kapa tsa fokola, ho bohlokoa ho boloka mocheso o tsitsitseng ka har'a moqomo oa extruder. Ho futhumatsa lisebelisoa ho lokela ho qojoa ho fokotsa ho se phethahale, kahoo hangata moqomo o futhumatsoa butle-butle ho tloha ka morao ho ea pele. Thempereichara e boetse e bolokoa ho sebelisoa letoto la li-fan le lisebelisoa tsa ho pholisa metsi pele sehlahisoa sa hau se fetisetsoa ka har'a hlobo.
Khamphani ea rona e na le boiphihlelo bo bongata indastering ea ho etsa mechini ea polasetiki. Lihlahisoa tsa rona tsa mantlha li kenyelletsa mochini oa extrusion oa polasetiki, mochini o hlabollang oa polasetiki, mochini oa polasetiki oa pelletizing joalo-joalo. Lihlahisoa tsa rona li na le setifikeiti sa CE le SGS. Amohela potso ea hau!
