Plastics extrusion ndeyepamusoro-vhoriyamu yekugadzira maitiro umo purasitiki yakasvibirira inonyungudutswa uye kuumbwa kuita inoenderera chimiro…
Extrusion inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana.Muchiyedzo ichi, isu tinoongorora epurasitiki extrusion ne screw extruder.Maextruder akadaro anowanikwa zvakanyanya muindasitiri yepurasitiki.
Chii Chinoitika mune Extruder?
Iyo screw mune extruder inotenderera uye inovandudza yakakwana kumanikidza kumanikidza zvinhu kuti zvipfuure nekufa uye kugadzira zvigadzirwa zvine inodiwa geometry.
Zvikamu zveExtruder
Pane zvinhu zvishanu zvakakosha muextruder: screw, extruder drive, barrel, feed hopper, uye kufa.Mwoyo weextruder is helical screw iyo inofambisa kutakura, kudziyisa, kunyunguduka, uye kusanganiswa kwepurasitiki.An extruder drive imota yemagetsi inopa simba rekutenderedza sikuruu.Kugadzikana uye hutano hwezvigadzirwa zvinoenderana zvakanyanya nekugadzirwa kwescrew.Iyo screw inoiswa mu extruder barrel iyo inopa kudziyisa uye kutonhora kugona.Iyo mbishi inopihwa kubva kune feed hopper iyo yakabatana nedhiramu nehuro yekudyisa.Iyo feed hopper yakagadzirirwa kubata epurasitiki pellets uye kuona kuyerera kwakadzikama kwema pellets mudhiramu.Iyo inofa iri panzvimbo yekubuda kweiyo extruder uye inosarudza chimiro chechigadzirwa.Kune marudzi akawanda ekufa, kusanganisira tubing dies, flat film inofa, uye firimu rinoputika rinofa.Mune iyi lab, tinoshandisa annular tubing die.Ziva kuti saizi uye chimiro chezvakaburitswa zvigadzirwa hazvina kunyatso kuenzana nehukuru uye chimiro chefa nekuda kwekukwevera pasi, kutonhora, kuzvimba, uye kuzorora kweiyo yakawedzera polymer.
Extrusion Lines
Kuwedzera kune extruder, chirongwa chekuwedzera chinoda kumusoro uye kudzika midziyo.Midziyo mikuru yetambo yeextrusion kubata resin, kuomesa sisitimu, extruder, post-shaping kana calibrating mudziyo, inotonhorera mudziyo, kutora-up mudziyo, uye cutter kana saw.Mutsetse weextrusion mulabhu yedu unosanganisira extruder, take-off roller, uye chigero chemvura inotonhorera.
