(1) Kenyelletso easekrufuru se le seng sa extruder
Li-extruder tse nang le sekoahelo se le seng, joalo ka ha lebitso le fana ka maikutlo, li na le sekoti se le seng ka har'a barrel ea extruder. Ka kakaretso, bolelele bo sebetsang bo arotsoe ka likarolo tse tharo, 'me bolelele bo sebetsang ba likarolo tse tharo bo khethoa ho ea ka bophara ba sekoti, sekontiri le botebo ba screw,' me ka kakaretso e aroloa ho ea ka tlaleho e 'ngoe le e' ngoe bakeng sa karolo ea boraro.
Karolo ea pele: ho qala ka khoele ea ho qetela ea koung ea phepelo, e bitsoa karolo ea ho tsamaisa. Boitsebiso mona ha bo hlokehe hore bo be polasetiki, empa bo tlameha ho behoa pele le ho hatelloa. Nakong e fetileng, khopolo ea khale ea extrusion e ne e lumela hore thepa mona ke 'mele o hlephileng. Hamorao, ho ile ha pakoa hore thepa e teng mona e hlile e le polaka e tiileng, e bolelang hore thepa e mona e petelitsoe. Mokokotlo o tiile joaloka polaka, hafeela e qeta mosebetsi oa ho fana ka thepa, ke mosebetsi oa eona.
(2) Ho sebelisoa ha screw extruder e le 'ngoe
The extruder single-screw e sebelisoa haholo ho fetisoa ha liphaephe, lishiti, lipoleiti, le lisebelisoa tsa profil, le granulation ea lisebelisoa tse ling tse fetotsoeng.
(1) Kenyelletso eamafahla a hlabang extruder
Mafahla-screw extruder e kenyelletsa litsamaiso tse latelang. The screw system haholo-holo e phethela polasetiki le mokhoa oa ho tsamaisa thepa, o nang le tšusumetso e kholo ts'ebetsong le boleng ba sehlahisoa se felileng.
① Sistimi ea ho fepa: ho kenyelletsa hopper, enjene e susumetsang, le enjene ea ho fepa. E ka thibela ho bokellana ha thepa le ho nolofatsa ho kena ha eona ka thelelo boema-kepeng ba phepelo.
② Sistimi ea ho futhumatsa ka ntle: Haholo-holo sebelisa molamu oa ho futhumatsa le cylinder ho futhumatsa thepa hantle le ho khothaletsa polasetiki.
③Sistimi ea ho futhumatsa: Sisteme ea phapanyetsano ea mocheso e entsoeng ka oli ea phetisetso ea mocheso kapa metsi e sebelisoa ho fokotsa mocheso oa fuselage, e le ho laola mocheso oa silindara ka nepo.
④ Sistimi ea ho fetola skrineng sa Hydraulic: Sebelisa li-filters tse ka nkeloang sebaka ho thibela litšila, ho ntlafatsa boemo ba polasetiki, le ho netefatsa ho ts'oana le botsitso ba boleng ba lisebelisoa.
Mohlala oa tšebeliso ea twin-screw extruder: fiber ea khalase e matlafalitsoe, granulation e thibelang lelakabe (joalo ka PA6, PA66, PET, PBT, PP, PC e matlafalitsoeng ka lelakabe, joalo-joalo), granulation e phahameng (joalo ka PE, PP e nang le 75% CaCO3), granulation ea thepa e sa utloeng mocheso. (joalo ka PVC, lisebelisoa tsa cable tsa XLPE), masterbatch ea mebala e teteaneng (joalo ka ho tlatsa 50% toner), anti-static masterbatch, alloy, colouring, low filling blend granulation, cable material granulation (E kang sheath material, insulating material), XLPE pipe material granulation (e kang masterbatch bakeng sa ho tšela metsi a chesang), motsoako oa polasetiki oa thermosetting le extrusion (joalo ka phenolic). resin, epoxy resin, ho roala phofo), sekhomaretsi se chesang se qhibilihisang, PU reactive extrusion granulation (joalo ka EVA hot melt sekgomaretsi, polyurethane), K resin, SBS devolatilization granulation, joalo-joalo.
Mehlala ea ts'ebeliso ea screw extruder e le 'ngoe:e loketseng liphaephe tsa PP-R, lipeipi tsa khase tsa PE, liphaephe tsa PEX tse amanang le sefapano, liphaephe tse entsoeng ka aluminium-polasetiki, liphaephe tsa ABS, lipeipi tsa PVC, lipeipi tsa mantlha tsa silicon tsa HDPE le liphaephe tse fapaneng tse kopantsoeng hammoho; e loketseng bakeng sa PVC, PET, PS, PP, PC le litlaleho tse ling le lipoleiti, le li-plastiki tse ling tse kang li-filaments, lithupa, joalo-joalo; ho lokisa lebelo la extruder le ho fetola sebopeho sa screw extrusion ho ka sebelisoa ho hlahisa PVC le polyolefin. Le lintlha tse ling tsa polasetiki.
