Tsela ea ho khetha polasetiki botjha ha thepa granulator (extruder)?

Taba ea mantlha, moreki o hloka ho hlalosa sebopeho le mofuta oa thepa e nchafalitsoeng hape a hlahlobe bokhoni ba ho e sebelisa hape (kg / hr).
Oo ke mohato oa mantlha oa mochini o sebelisang bocha o khethiloeng. Bareki ba bang ba bacha ba lula ba sa utloisise mechini ea polasetiki e nchafatsang, e ka sebelisang mefuta eohle ea polasetiki hape. Ebile, polasetiki ea mofuta o fapaneng e na le litšobotsi le likarolo tse fapaneng. Mocheso oa bona o qhibilihisitsoeng le khatello ea extruding li fapane haholo. Extruder ea polasetiki e akaretsang e ka pheta-pheta hape ea sebelisa granulate / pelletize li-plastiki tsa rona tsa letsatsi le letsatsi. Tse tloaelehileng ke polypropylene le polyethylene, joalo ka filimi ea polasetiki, mekotla e lohiloeng, mekotla e bonolo, likotlolo, libarele le lintho tse hlokoang letsatsi le letsatsi. Bakeng sa lipolasetiki tse khethehileng tse kang li-plastiki tsa Engineering ABS, lisebelisoa tsa botlolo tsa PET, jj li hloka polasetiki e khethehileng ea polasetiki.

Taba ea bobeli, mofuta oa extruder o etsa qeto ea boholo ba bophara ba screw le bokhoni ba ho e sebelisa hape. Nakong ea ho khetha mofuta oa extruder, moreki a ke ke a ela hloko mohlala oa extruder feela, empa a amehe le ka mochini o sebetsang hantle. Maemong a mangata, bophahamo ba thepa bo tšoaetsoeng bo emela bokhoni ba tlhahiso. PURUI polasetiki botjha ha thepa sehlopha filwe extruder akarelletsa ML ea mohlala extruder, SJ ea mohlala extruder le TSSK ea mohlala mafahla nsete extruder, e neng e sebelisoa bakeng sa filimi polasetiki kapa mokotla granulating / pelletizing, tenyetseheng polasetiki botjha ha thepa hammoho le phetolo polasetiki, PET botlolo flake, polasetiki kopanya le mong'a methaka .

Taba ea boraro, moreki o hloka ho hopotsoa mofani oa thepa ka metsi a seng a sebelisitsoe hape (litaba tse litšila) le liperesente tse hatisitsoeng PURUI e fane ka screw screw e le 'ngoe feela e ka sebetsana le thepa e hloekileng kapa thepa e hlatsoitsoeng kahare ho metsi a 5%. Hang ha lintho tse bonahalang recycled lintho tse litšila e feta 5% ho 8%, moreki lokela ho khetha habeli sethaleng botjha ha thepa extruder bakeng botjha ha thepa. Mabapi le thepa e hatisitsoeng, mofani oa thepa o hloka ho matlafatsa sistimi ea vacuum le sistimi ea ho sefa.

Ea bone, ka ho ba le tlhahiso e fapaneng ea barekisi, basebelisi ba ka khetha li-granulators tsa polasetiki (extruder) tse nang le litekanyo tse tsoetseng pele tsa tekheniki le litheko tse loketseng ka papiso e otlolohileng kapa e otlolohileng. "Longitudinal" e bolela hore mekhahlelo e ka sehloohong ea tekheniki ea granulator ea polasetiki (extruder) e lokela ho fihlela maemo a indasteri mme e hlahlojoe ho latela maemo a indasteri. "Horizontal" ke papiso e ipapisitseng le lipehelo tsa tekheniki ea li-granulators tse tšoanang tsa polasetiki (extruder) sebakeng sa heno le kantle ho naha.

Ea bohlano, ho latela tekanyetso, basebelisi ba potoloha le barekisi ba ka bang teng. Ka lintlha tsa mochini oa puisano tse nang le bokhoni ba moralo ba bafani, theknoloji e holileng tsebong, ts'ebetso ea mochini le kamora ts'ebeletso, jj.

Ntlha ea botšelela, kamora ho tseba lenane la ho qetela la barekisi, bareki ba ka ea ho ea batlisisa moetsi oa granulator (extruder) le theko ea granulator (extruder). Haholo-holo ho batlisisa boholo ba moetsi, matla a tlhahiso, le botumo ba bareki ba sebelisang lisebelisoa. Se ke oa tšaba leeto le lelelele. Senotlolo sa ho reka lisebelisoa ke ho reka mochini o bolokang chelete e ngata o nang le theknoloji e matla le ts'ebeletso ea kamora ho rekisa, e le hore ho se ts'oenyehe nakong ea ts'ebeliso nakong e tlang. Haeba u reka thepa e theko e tlase kapa e haufinyane, ts'ebetso le boleng ba sehlahisoa bo tla ba bo sa tsitsang mme ts'ebeliso e tla sebelisoa.
