Mitundu ya extruders

Extruder akhoza kugawidwa mu screw single, twin screw ndi multi screw extruder malinga ndi kuchuluka kwa zomangira.Pakali pano, limodzi wononga extruder ndi ambiri ntchito, oyenera extrusion processing wa zipangizo ambiri.Amapasa wononga extruder ali zochepa kwaiye ndi mikangano, ndi yunifolomu akumeta ubweya wa zinthu, lalikulu wononga wononga mphamvu, ndi khola extrusion voliyumu, okhala nthawi yaitali zinthu mu mbiya, ndi yunifolomu mixi ng.SJSZ mndandanda conical amapasa screw extruder ali ndi makhalidwe a extruder anakakamizika, apamwamba, kusinthasintha lonse, moyo wautali, otsika kukameta ubweya mlingo, zovuta kuwonongeka kwa zipangizo, kusakaniza bwino ndi ntchito plasticizing, akamaumba mwachindunji zipangizo ufa, etc., ndi kutentha basi. control, Vacuum utsi ndi zida zina.

M'zaka zaposachedwa, anthu achita kafukufuku wambiri wongopeka komanso woyeserera pa screw, ndipo pali mitundu pafupifupi zana ya zomangira mpaka pano, ndipo wamba ndi mtundu wolekanitsa, mtundu wa shear, chotchinga, mtundu wa shunt ndi mtundu wamalata. .Kuchokera pamalingaliro a chitukuko cha screw-single, ngakhale ma extruders osakwatiwa akhala angwiro m'zaka zaposachedwa, ndikukula kosalekeza kwa zida za polima ndi zinthu zapulasitiki, zomangira zatsopano zamtundu watsopano komanso ma extruders apadera apadera azituluka.

Mu pulasitiki extrusion akamaumba zida, pulasitiki extruder nthawi amatchedwa injini yaikulu, ndi wotsatira zida pulasitiki extrusion akamaumba makina amatchedwa makina wothandiza.Pulasitiki extruder imapanga mapasa-screw, screw angapo, ngakhale ilibe mitundu yosiyanasiyana ya makina monga screw rod ndi choyambirira single screw ndodo kupyola zaka 100 za chitukuko.Popeza ma extruder apulasitiki amagwira ntchito m'mafakitale osiyanasiyana ndikutukuka mozama, ndizotheka kusinthana ndikugwiritsa ntchito msika.Munjira zosiyanasiyana, sinthani luso laukadaulo.Izi sizidzangothandiza kupititsa patsogolo gawo lonse la mafakitale, komanso kuthandiza makampani onse kuti apite patsogolo mogwirizana ndi mgwirizano wa akatswiri a chikhalidwe cha anthu komanso kupititsa patsogolo mpikisano wapadziko lonse.
