Izinhlobo zePlastiki Extrusion

Kunokwehluka kwinqubo ye-extrusion kuye ngokuthi hlobo luni lwe-extrusion eyenziwayo.Nakhu ukubuka izinhlobo ezahlukene ze-extrusion, kanye nomehluko kusukela kunqubo eyisisekelo ngayinye.

I-Extrusion Yeshidi

I-extrusion yeshidi, eyaziwa nangokuthi i-extrusion yefilimu, isetshenziselwa ukwenza amashidi epulasitiki namafilimu, futhi ngokuvamile iyahluka kunqubo eyisisekelo yokukhipha mayelana nenqubo yokupholisa.Kunokuba usebenzise ukugeza kwamanzi ukupholisa umkhiqizo osuphelile, amashidi ayapholiswa ngokudonswa ngochungechunge lwama-pinch rollers amathathu kuya kwamane.Ngaphezu kokupholisa umkhiqizo, ama-roller nawo asetshenziselwa ukunquma ubukhulu bomkhiqizo wokugcina.

I-Blown Film Extrusion

I-Blown film extrusion isetshenziselwa ukwenza imikhiqizo efana nezikhwama zokuthenga zepulasitiki.Inqubo iyafana nenqubo ye-extrusion eyisisekelo kuze kufike iphuzu le-resin engena kufa.Idayidi iyisilinda esiqondile esivuleke esiyindilinga.I-resin encibilikisiwe idonswa phezulu kusuka efashini ngama-nip rolls aphezulu ngaphezu kwedayizi.Ukushintsha ijubane lawa ma-nip roller kuzoshintsha ukujiya kwefilimu yepulasitiki.Eduze kwefa kuhlezi indandatho yokupholisa esekwe ekugelezeni komoya, epholisa umkhiqizo njengoba uya phezulu.Umoya uvuthela ku-die, ukwandisa umkhiqizo okhishiwe.Le filimu ingase ihlanganiswe noma iphrintwe, isikwe ibe yizimo, noma ivalwe ngokushisisa kweminye imikhiqizo.

I-Tubing Extrusion

I-extrusion yamashubhu isetshenziselwa ukwenza imikhiqizo efana notshani noma ishubhu lezokwelapha.Inqubo iyafana nenqubo eyisisekelo kuze kube yilapho i-resin ifinyelela kufa.Iphinikhodi (mandrel) ibekwe ngaphakathi kwefa.I-resin encibilikisiwe iphonswa ku-die, yakha ezungeze i-mandrel.Yile ndlela ukwakheka kwe-tubing okungenalutho okwakhiwa ngayo.Umfutho womoya usetshenziselwa ukukala ubukhulu beshubhu.

Lezi ezinye zezinqubo ezimbalwa ezisetshenziselwa ukukhishwa kwepulasitiki.Inzuzo enkulu kuzo zonke lezi zinhlobo zenqubo ye-plastic extrusion ukuthi zinikeza amathuba amaningi wejometri ngaphezu kwezinye izinhlobo zokukhiqiza amafomu epulasitiki.Umehluko wobumo nosayizi ongakhiqizwa mkhulu, okuwukuphela komkhawulo ukuthi umkhiqizo kufanele ube nephrofayili eqhubekayo.
