Yintoni ukubumba ukuvuthela?Uthini umgaqo wokubumba isivuthelo?

Ukubumba ukuvuthela, okwakwaziwa njengokubumba umngxuma wokuvuthela, kukukhula ngokukhawuleza kweplastiki.Inkqubo yokubumba ukuvuthela NgeMfazwe Yehlabathi II, amavili avuthelweyo aqale asetyenziselwa ukuvelisa iingqayi zepolyethylene ezixinene kancinci.Ngasekupheleni kweminyaka yee-1950, kunye nokuzalwa kwe-polyethylene ephezulu kunye nokuphuhliswa koomatshini bokubumba, iteknoloji yokubumba i-vuthela e-Kunshan yayisetyenziswa ngokubanzi.Umthamo wezikhongozeli ezingenanto unokufikelela kumawaka eelitha, kwaye enye imveliso yamkela ulawulo lwekhompyutha.Iiplastiki ezifanelekileyo ukubumba ukubetha zibandakanya i-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njl.

vuthela ukubumba

Ngokwendlela yokuvelisa i-parison, ukubumba ukuvuthela kunokwahlulwa ku-extrusion blow blowing kunye ne-injection blow blowing.Ezi zisanda kuphuhliswa ziquka ukubunjwa kwe-multi-layer blow and stretch blow molding.I-tubular parison yeplastiki efunyenwe nge-extrusion okanye ukubunjwa kwenaliti ye-thermoplastic resin ifakwe kwi-mold ye-thermoplastic ngelixa ishushu (okanye ishushu kwisimo esithambileyo), kwaye umoya ocinezelweyo ungeniswa kwi-parison ngokukhawuleza emva kokuba umngundo uvaliwe ukuvuthela i-parison yeplastiki. .Yandisa kwaye inamathele ngokusondeleyo kudonga lwangaphakathi lwesikhunta, kwaye emva kokupholisa kunye nokudiliza, iimveliso ezahlukeneyo ezingenanto zifunyenwe.Inkqubo yokwenziwa kwefilimu evuthelweyo ifana kakhulu nomgaqo wokuvuthela ukubunjwa kweemveliso ezingenanto, kodwa ayisebenzisi i-mold.Ngokombono wokuhlelwa kweteknoloji yeplastiki, inkqubo yokubumba ifilimu evuthelweyo iqukwa ngokubanzi kwi-extrusion.Inkqubo yokubumba isivuthe ekuqaleni yayisetyenziselwa ukuvelisa iibhotile ze-polyethylene eziphantsi ngexesha leMfazwe Yehlabathi yesiBini.Ngasekupheleni kwee-1950, kunye nokuzalwa kwe-polyethylene ephezulu kunye nokuphuhliswa koomatshini bokubumba, iteknoloji yokubumba yayisetyenziswa ngokubanzi.Umthamo wezikhongozeli ezingenanto unokufikelela kumawaka eelitha, kwaye enye imveliso yamkela ulawulo lwekhompyutha.Iiplastiki ezifanelekileyo ukubumba ukubetha zibandakanya i-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njl.
