Ama-extruder ama-twin screw asetshenziswa kabanzi ekuguqulweni ngokomzimba kwama-polymer, futhi angasetshenziswa nasekukhipheni imikhiqizo ebunjiwe. Izici zayo zokudla zingcono, futhi inemisebenzi engcono yokuxuba, yokungenisa umoya, kanye nokuzihlanza kune-extruder eyodwa yesikulufo. Ngokuhlanganisa izinhlobo ezahlukene zezinto zesikulufo, i-extruder yama-twin-screw enomsebenzi wokukhipha umoya eklanywe ngendlela yamabhulokhi okwakha ingasetshenziswa kulezi zici ezilandelayo.
- Ukukhiqizwa kwe-masterbatch
Ingxube yezinhlayiya zepulasitiki kanye nezithasiselo iyiqoqo eliyinhloko. Izithasiselo zifaka phakathi ama-pigment, ama-filler kanye nezithasiselo ezisebenzayo. I-extruder enama-twin-screw iyithuluzi eliyinhloko lomugqa wokukhiqiza we-masterbatch, esetshenziselwa ukuhlanganisa, ukuhlakaza kanye nokuxuba izithasiselo ku-polymer matrix.
- Ukuguqulwa kokuxuba
Nikeza ukusebenza okuhle kakhulu kokuxuba phakathi kwe-matrix kanye nezithasiselo, ama-filler. I-fiber yengilazi iyinto ebaluleke kakhulu yokuqinisa, kodwa eminye imicu ingahlanganiswa nezithwali ze-polymer. Ngokufaka imicu nokuhlanganisa nama-polymer, izinto ezinamandla aphezulu kanye nokumelana okukhulu komthelela zingatholakala, futhi ngesikhathi esifanayo, isisindo kanye nezindleko kungancishiswa.
- Ukukhipha ugesi
Ngenxa yokuhlanganiswa kwe-screw ezimbili, inqubo yokugunda impahla endaweni ye-meshing ivuselela njalo ungqimba olungaphezulu lwento futhi ithuthukise umphumela wokukhipha, ukuze i-extruder enama-twin screw ibe nokusebenza okungcono kune-extruder ene-single-screw ephelelwe yisikhathi. Ukusebenza kokukhipha.
- Ukukhipha okuqondile
I-extruder enama-twin screw ingahlanganisa nokuxuba nokubumba i-extrusion. Ngokusebenzisa ikhanda elithile kanye nemishini efanele engezansi komfula, ingakhiqiza imikhiqizo eqediwe ngendlela ephumelela kakhulu, njengefilimu, amapuleti, amapayipi, njalo njalo. I-extrusion eqondile ingashiya izinyathelo zokupholisa nokufaka i-pelletizing kanye nokuvuselela nokushisa nokuncibilikisa, futhi izinto zibhekene nokucindezeleka okuncane kokushisa kanye nokucindezeleka kokucheba. Yonke inqubo ingonga amandla futhi ifomula ingalungiswa kalula.
