Ibhodlela Eligcwele Okushisayo Ibanga Le-PET Resin Isithombe Esifakiwe
  • Ibhodlela le-PET Resin eligcwele ngokushisayo

Ibhodlela le-PET Resin eligcwele ngokushisayo


  • Izici nokusebenza:Inomumo odonswa phezulu, ubucwebe obuzinzile, kulula ukulawula ukusatshalaliswa kokuqina kodonga, izinga eliphansi lokukhishwa kwengcindezi-insalela yalo lonke ibhodlela, kanye nokuncipha kokushisa okuzinzile ekuphepheni kwebhodlela.Ngaphezu kwalokho, ama-chips anikezelwe amabhodlela agcwele ukushisa athuthukisiwe futhi enzelwe isiphuzo esiphakathi esidinga ukwelashwa kokugcwalisa inzalo eshisayo.
  • Izinkambu zesicelo:Amabhodlela esiphuzo setiye, ijusi kanye nezinye iziphuzo zemidiya ezidinga ukwelashwa kokugcwalisa inzalo eshisayo.
  • Izinto zokusetshenziswa eziyinhloko:I-PTA, MEG, IPA

    Isingeniso Somkhiqizo

    Ama-chips e-polyester ebangeni eligcwele ibhodlela agcwalisiwe athuthukisiwe futhi akhiqizwa ngokukhethekile amabhodlela agcwalisa-shisayo ngokusho kwalezo ziphuzo zetiye、iziphuzo zejusi yezithelo nezinye iziphuzo zohlobo oluphakathi zidinga ukuthi zifakwe ebhodleleni elishisayo ukuze kubulawe inzalo.

    /uhlelo lokusebenza/

    Uhlobo lomkhiqizo lubonisa okuqukethwe kwensimbi esindayo ephansi, okuqukethwe okuphansi kwe-acetaldehyde, inani lombala elihle, i-viscosity ezinzile futhi elungele ukucutshungulwa.Nge-recipe yenqubo eyingqayizivele kanye nobuchwepheshe obuthuthukisiwe bokukhiqiza, umkhiqizo, lapho wenziwa i-thermoformed ku-SIPA, SIDEL, ASB njll. imishini eyinhloko yokwenza amabhodlela ngaphansi kwezimo ezijwayelekile, unezinga eliphezulu le-tropism, i-crystallinity ezinzile kanye nomswakama omuhle ngezinga eliphansi lokukhulula ukucindezeleka ibhodlela lonke, izinga lokufinyela okushisayo okuzinzile kanye nezinga eliphezulu lomkhiqizo oqediwe ekwenzeni amabhodlela, linganelisa imfuneko yokufakwa emabhodleleni cishe ku-90°C futhi livikele iziphuzo ekushintsheni kombala noma ekufakweni kwe-oxidation ngesikhathi sokugcina futhi kuvimbele ukuwohloka kwamabhodlela.

    Izimo Ezijwayelekile Zokucubungula

    Ukomisa kuyadingeka ngaphambi kokucubungula ukuncibilika ukuvimbela i-resin kusuka ku-hydrolysis.Izimo ezijwayelekile zokomisa ukushisa komoya okungu-165-185 ° C , isikhathi sokuhlala samahora angu-4-6, izinga lokushisa lamazolo lingaphansi -40 0C.

    Izinga lokushisa lomphongolo elijwayelekile lingaba ngu-285-298°C.
