(1) Intshayelelo yeisikrufu esinye isikrufu
I-extruder-screw extruder, njengoko igama libonisa, zine-screw enye ngaphakathi kwi-barrel extruder.Ngokubanzi, ubude obusebenzayo bahlulahlulwe baba ngamacandelo amathathu, kwaye ubude obusebenzayo bamacandelo amathathu bumiselwa ngokwe-diameter ye-screw, i-pitch, kunye nobunzulu be-screw, kwaye yahlulahlulwe ngokubanzi ngokobalo ngalunye kwisithathu.
Icandelo lokuqala: ukuqala ukusuka kumsonto wokugqibela wezibuko lokutya, libizwa ngokuba licandelo lokuhambisa.Izinto apha azidingeki ukuba zenziwe ngeplastiki, kodwa kufuneka zifudumeze kwaye zicinezelwe.Ngaphambili, ithiyori endala ye-extrusion yayikholelwa ukuba izinto ezilapha ngumzimba okhululekileyo.Kamva, kwaqinisekiswa ukuba izinto ezilapha ziyiplagi eqinileyo, okuthetha ukuba izinto ezilapha zicudisiwe.Umva uqinile njengeplagi, ngoko nje ukugqiba umsebenzi wokuhambisa, ngumsebenzi wawo.
(2) Ukusetyenziswa kwe-screw extruder enye
I-extruder-screw extruder isetyenziswa ikakhulu kwi-extrusion yemibhobho, amaphepha, iipleyiti, kunye nezinto ezifakwe kwiprofayili, kunye ne-granulation yezinto ezithile ezilungisiweyo.
(1) Intshayelelo yei-twin-screw extruder
I-twin-screw extruder ibandakanya ezi nkqubo zilandelayo.Inkqubo ye-screw ngokuyinhloko igqiba iplastiki kunye nenkqubo yokuhambisa izinto eziphathekayo, enempembelelo enkulu ekusebenzeni kunye nomgangatho wemveliso egqityiweyo.
① Inkqubo yokutya: kubandakanya i-hopper, i-motor eshukumisayo, kunye nemoto yokutya.Inokuthintela ukuqokelela kwezinto kwaye iququzelele ukungena kwayo ngokugudileyo kwi-port feed.
② Inkqubo yokufudumala yangaphandle: Ngokukodwa sebenzisa intonga yokufudumeza kunye ne-cylinder ukutshisa izinto ngokufanelekileyo kunye nokukhuthaza iplastiki.
③Inkqubo yokupholisa: Inkqubo yokutshintshiselana kobushushu eyenziwe ngeoli yokuhambisa ubushushu okanye amanzi isetyenziselwa ukunciphisa ubushushu be-fuselage, ukuze kulawulwe ngokufanelekileyo ubushushu be-cylinder.
④ Inkqubo yokutshintsha isikrini seHydraulic: Sebenzisa izikrini zokucoca ezinokutshintshwa ukuze uthintele ukungcola, uphucule inqanaba leplastiki, kwaye uqinisekise ukufana kunye nokuzinza komgangatho wezinto eziphumayo.
Umzekelo wokusetyenziswa kwe-twin-screw extruder: i-fiber yeglasi yomeleziwe, i-flame retardant granulation (efana ne-PA6, i-PA66, i-PET, i-PBT, i-PP, i-PC eyomeleziweyo i-flame retardant, njl. njl.), i-filler granulation ephezulu (efana ne-PE, i-PP ezaliswe nge-75% ye-CaCO3), i-granulation yezinto eziphathekayo ezinobushushu. (ezifana ne-PVC, i-XLPE cable material), i-masterbatch yombala ongqindilili (njengokuzaliswa kwe-50% toner), i-anti-static masterbatch, i-alloy, i-coloring, i-low filling blend granulation, i-cable material granulation (Efana ne-sheath material, insulating material), XLPE umbhobho izinto granulation (ezifana masterbatch for crosslinking amanzi ashushu), thermosetting plastic mixing kunye extrusion (ezifana phenolic resin, epoxy resin, umgubo ukutyabeka), incanyazo eshushu inyibilika, PU reactive extrusion granulation (ezifana EVA eshushu inyibilika ancamathelise, polyurethane), K resin, SBS devolatilization granulation, njl.
Imizekelo yosetyenziso lwe-screw extruder enye:ifanelekile kwimibhobho ye-PP-R, imibhobho yegesi ye-PE, i-PEX i-cross-linked pipes, i-aluminium-plastic composite pipes, imibhobho ye-ABS, imibhobho ye-PVC, imibhobho ye-silicon ye-HDPE kunye nemibhobho edibeneyo edibeneyo edibeneyo;ifanelekile kwi-PVC, i-PET, i-PS, i-PP, i-PC kunye nezinye iiprofayili kunye namacwecwe, kunye nezinye iiplastiki ezinjengeentambo, iintonga, njl.;ukulungelelanisa isantya se-extruder kunye nokutshintsha isakhiwo se-screw extrusion ingasetyenziselwa ukuveliswa kwe-PVC kunye ne-pololefins.Kwaye ezinye iiprofayili zeplastiki.
