Lo mehluko uthinta ikhwalithi yomkhiqizo kanye nokulawula inqubo. Ukuze kube lula, ukukhiqizwa kwevolumu ephezulu, aI-Single Plastic Screw Barrelifanele izidingo eziningi.I-Twin Screw Extruder BarrelsfuthiIzikulufo Ezimbili Zezikhiqizo Zepulasitikiuphumelele ekuxubeni okuyinkimbinkimbi.
Kuchazwa Ukukhishwa Kwesikulufa Esisodwa
Indlela I-Single Screw Extrusion Esebenza Ngayo
I-scrusion yesikulufu esisodwa isebenzisa isikulufu esisodwa esizungezayo ngaphakathi kombhobho oshisayo. Isikulufu siyisa ipulasitiki eluhlaza noma impahla yerabha phambili, lapho ukungqubuzana nokushisa kuncibilikisa khona. Impahla encibilikisiwe idlula idayisi ukuze yakhe umumo oqhubekayo. Ama-opharetha alawula amapharamitha enqubo yokhiye afana nezinga lokushisa lomgqomo (ngokuvamile li-160–180 °C), isivinini sesikulufu, nezinga lokushisa lokufa. Isivinini seyunithi yokuthatha kanye nezinga lokushisa lethangi lamanzi kusiza ukulawula ububanzi nokupholisa komkhiqizo wokugcina. Isikulufu siyasebenzaimisebenzi emithathu eyinhloko: ukudlulisa, ukuncibilika, nokuxuba. Idizayini yomgqomoizici ezifana ne-hard tempering kanye ne-chrome plating kunciphisa ukungqubuzana nokunamathela, okuqinisekisa ukusebenza kahle.
Izinzuzo ze-Single Screw Extrusion
Abakhiqizi bayakhethaisikulufa esisodwa extrusionngobulula bayo kanye nokusebenza kahle kwezindleko. Idizayini ivumela ukusebenza nokugcinwa kalula. Ukutshalwa kwezimali okuphansi kokuqala kanye nezindleko zokusebenza kukwenza kukhange amabhizinisi amaningi.Ukusebenza kahle kwamandlakuyagqama, njengoba uhlelo lisebenzisa ukufudumeza okulungiselelwe kanye nezingxenye ezihambayo ezimbalwa. Ama-opharetha angafinyelela ikhwalithi yomkhiqizo engaguquki ngokulungisa izinga lokushisa, ukucindezela, nesivinini sesikulufu. Lolu hlelo lusingatha inhlobonhlobo yezinto ezingavuthiwe, okulwenza lusebenziseke ngezindlela eziningi izidingo zokukhiqiza ezahlukene.
Ithiphu: Ukunakekelwa okuvamile kanye nokuqapha amandla ngesikhathi sangempela kungathuthukisa ukusebenza kahle nekhwalithi yomkhiqizo.
Imikhawulo Yesikulufa Esisodwa Extrusion
I-scrusion yesikulufu esisodwa ibhekene nezinselelo ezithile. Okukhiphayo kungase kungazinzi ngesivinini esikhulu sezikulufu, kunciphise amazinga okukhiqiza.
