Iyo mapatya-screw extruder yakakamurwa kuita inobata mhando uye isiri-inobatanidzwa mhando zvichienderana nenzvimbo dzehukama dzema screws maviri.Iyo mesh mhando yakakamurwa kuita chikamu mesh mhando uye yakazara mesh mhando zvinoenderana nedhigirii remeshing.Iyo twin-screw extruder yakakamurwa kuita mhando mbiri: iyo yakafanana dhizaini inotenderedza sikuru uye reverse inotenderera screw zvinoenderana neiyo screw inotenderera nzira.

Pazasi, Xiaobian inokupa pfupiso sumo nezve tekinoroji matambudziko emapatya-screw extruders.

1. Wedzera screw speed, iyo inobatsira kuumbwa kwebubble, kukura uye kuputika, izvo zvinobatsira kudzikisa kureba kwekuzadza kwechinyorwa mu screw groove, kuwedzera kuvandudzwa kweiyo misa yekutamisa nzvimbo, uye kugadzirisa devolatilization kushanda. ;zvisinei, iyo yakanyanyisa kumhanya inogadzira zvinhu Iyo nguva yekugara muchikamu che devolatilization yakaderedzwa zvakanyanya, uye devolatilization kunyatsoita kuderera.

2. The main screw speed, feed amount uye barrel set tembiricha ndizvo zvinonyanya kupesvedzera zvinhu zve devolatilization process mu twin-screw extruder.Izvi zvinhu zvinogona kukanganisa tembiricha yezvinhu, kuzara kwegorofu, nguva yekugara uye hurefu hwakazara hunoshanda, zvichikanganisa devolatilization munzira dzakawanda.Kune yakasarudzika maitiro, pane yakaringana yekushanda nzvimbo, uye kana iri yekushanda kwakagadzikana, yakanyanya kunaka devolatilization inogona kuwanikwa.

3, kuderedzwa kwakakodzera kwechikafu kunogona kuderedza chiyero chekuzadza kwechikamu chekuburitsa, kuitira kuti devolatilization ibudirire;asi yakanyanya kuderera vhoriyamu yekudyisa haingodzikisi huwandu hweextrusion uye kuchinjika, asiwo nekuti chiyero chekuzadza chakanyanya kuderera, hachina kukwana kuumba kunyunguduka Dziva rinoderedza kugona kwekupupa uye devolatilization, saka huwandu hwekudya hunofanira kunge hune mwero.

4. Kuwedzera nguva yekugara kwezvinhu muchikamu che devolatilization uye kuwedzera kureba kwechikamu che devolatilization kunogona kuvandudza kushanda kwe devolatilization.Nechikonzero ichi, inofungidzirwa kuwedzera kureba kwechikamu chekuburitsa uye kutora yakawanda-nhanho kupera muiyo screw chimiro dhizaini.
