Plastiki extrusion, lejoe la motheo la tlhahiso ea morao-rao, e phetha karolo ea bohlokoa indastering ea kaho. Ts'ebetso ena e lula e bōpa polasetiki e qhibilihisitsoeng hore e be li-profiles tse khethehileng, e fana ka tharollo e bobebe, e theko e tlaase le e fapaneng bakeng sa likarolo tse fapaneng tsa mohaho. Ha re hlahlobeng lintlha tsa tekheniki tsa extrusion ea polasetiki e amanang le lits'ebetso tsa kaho.
Ho Utloisisa Plastic Extrusion Line
Mohala oa polasetiki oa extrusion o na le likarolo tse 'maloa tsa bohlokoa tse sebetsang ka bonngoe:
- Extruder:Pelo ea tsamaiso, extruder e na le "screw conveyor" e qhibilihisang le ho hatella li-pellets tsa polasetiki. Moralo oa screw le litlhophiso tsa mocheso li bohlokoa bakeng sa phallo e nepahetseng ea thepa le boleng ba sehlahisoa.
- E-shoa:Hlobo ena e bōpehileng e etsa qeto ea boemo ba ho qetela ba polasetiki e extruded. Li-dies li ka ba tse rarahaneng, tsa theha libopeho tse rarahaneng bakeng sa lisebelisoa tse khethehileng.
- Lisebelisoa tsa Calibration:Ha extrudate e chesang e tsoa lefung, e ka 'na ea ruruha hanyenyane. Lisebelisoa tsa calibration li netefatsa hore profil e boloka litekanyo tsa eona tse lakatsehang ka mokhoa o laoloang oa ho pholisa.
- Lisebelisoa tsa ho futhumatsa:Bakeng sa lisebelisoa tse itseng kapa botenya ba profil, lisebelisoa tsa preheating li netefatsa mocheso o ts'oanang oa thepa pele li kena ka har'a lefu. Sena se ntlafatsa boleng ba sehlahisoa mme se fokotsa ho se lumellane.
- Lisebelisoa tsa ho Pholisa:Profaele e fetisitsoeng e hloka ho tiea ho boloka sebopeho sa eona. Lisebelisoa tse futhumatsang, tse kang libate tsa metsi kapa lithipa tsa moea, li pholisa polasetiki ka potlako ha e tsoa. Mokhoa oa ho pholisa o hloka ho laoloa ka nepo ho qoba ho khopama kapa ho phatloha.
- Yuniti ea ho hula:Yuniti ena e hula profil e fetisitsoeng ka lebelo le sa khaotseng moleng, e boloka tsitsipano le ho netefatsa ho nepahala ha dimensional.
- Setsi sa ho Seha:Joale profil e khaoloa ka bolelele bo lakatsehang ho sebelisoa lisakha kapa mekhoa e meng ea ho itšeha. Ho ipapisitse le ts'ebeliso, yuniti ea ho itšeha e kanna ea hokahana le lits'ebetso tse tlase tse kang ho bokellana kapa ho khoaela.
Khetho ea Lintho bakeng sa Likopo tsa Kaho
Khetho ea resin ea polasetiki bakeng sa extrusion e itšetlehile ka ts'ebeliso e khethehileng le thepa e lakatsehang:
- PVC (Polyvinyl Chloride):Thepa e theko e tlaase le e sebelisoang haholo bakeng sa liphaephe, li-profiles tsa lifensetere, le siding ka lebaka la ho leka-lekana ha eona ho matla, ho tiea le ho hanyetsa boemo ba leholimo.
- HDPE (Polyethylene e Matla a Phahameng):E tsebahala ka matla a eona a ikhethang le ho tšoarella ha eona, HDPE e loketse liphaephe, litanka le lisebelisoa tse hlokang khanyetso e matla, joalo ka lits'ebetso tsa drainage tse ka tlas'a lefatše.
- PP (Polypropylene):Sesebelisoa se bobebe ebile se hanana le lik'hemik'hale, PP e fumana ts'ebeliso lits'ebetsong tse kang li-membrane tse sa keneng mongobo, likarolo tsa kaho ea kahare, esita le lisebelisoa tse ling tsa liphaephe.
- ABS (Acrylonitrile Butadiene Styrene):E fana ka tekanyo e ntle ea matla, ho tiea, le ho hanyetsa tšusumetso, ABS e sebelisetsoa liphaephe, tsamaiso ea drainage, le likarolo tse ling tsa mohaho tse se nang sebopeho.
Ho ntlafatsa Ts'ebetso: Tlhokomelo ea Extruder bakeng sa Boleng bo Tšoanang
Tlhokomelo ea kamehla ea mohala oa extrusion ke oa bohlokoa bakeng sa boleng bo tsitsitseng ba sehlahisoa le ts'ebetso e sebetsang hantle. Mekhoa ea bohlokoa ea tlhokomelo e kenyelletsa:
- Ho hloekisa Screw:Ho hloekisa khafetsa screw ea extruder ho tlosa thepa efe kapa efe e setseng ea polasetiki e ka senyang kapa ea silafatsa li-extrusions tsa nako e tlang.
- Tlhokomelo ea Moqomo:Moqomo oa extruder o hloka ho hlahlojoa le ho hloekisoa nako le nako ho netefatsa kabo e nepahetseng ea mocheso le ho thibela ho bokellana ha thepa.
- Tlhokomelo ea Lefu:Ho hloekisa li-Die ho bohlokoa ho boloka ho nepahala ha sebopeho le pheletso ea profil e fetisitsoeng. Ho boetse hoa hlokahala tlhahlobo ea kamehla ea hore na ha e senyehile hakae.
- Tlhokomelo ea Sisteme ea Khale:Lisebelisoa tsa calibration li tlameha ho sebetsa ka nepo ho netefatsa litekanyo tse lumellanang tsa profil. Sena se ka kenyelletsa ho hloekisa li-sensor le litsamaiso tsa taolo ea calibrating.
Qetello: Bokamoso ba Plastiki Extrusion ka Kaho
Theknoloji ea extrusion ea polasetiki e lula e fetoha, e fana ka menyetla e mecha bakeng sa indasteri ea kaho. Mona ke tse ling tse khahlisang tseo u ka li shebellang:
- Liprofaele tse Kopantsoeng:Ho kopanya polasetiki le lisebelisoa tse matlafatsang joalo ka fiberglass kapa likhoele tsa lehong ho ka theha liprofaele tse matla le ho feta tse loketseng lits'ebetso tsa meralo.
- Saense e Tsoetseng Pele ea Lintho:Nts'etsopele ea li-additives tse thibelang mollo le li-polymers tse thehiloeng ho li-bio li ka ntlafatsa ts'ireletseho le botsitso ba likarolo tsa polasetiki kahong.
- Ho kopanya le Automation:Indasteri ea kaho e amohela li-automation, 'me mehala ea polasetiki ea extrusion e ntse e tsoela pele ho rarahana le ho feta. Ho kopanngoa le liroboto le litsamaiso tse sebetsanang le thepa e ikemetseng li ka tsamaisa tlhahiso le ho ntlafatsa ts'ebetso.
Ka ho utloisisa likarolo tsa tekheniki tsa extrusion ea polasetiki, litsebi tsa kaho li ka sebelisa theknoloji ena e fapaneng ho fihlela bokhoni ba eona bo felletseng. Ho tloha ho ntlafatsa khetho ea thepa ho ea ho ho netefatsa tlhokomelo e nepahetseng ea mohala, ho tsepamisa maikutlo ho botsebi ba tekheniki ho tla kenya letsoho mekhoeng ea kaho ea boleng bo holimo, e baballang chelete e ngata, le ea moshoelella.
