Ibhodlela le-crystallized bottleneck lisetshenziselwa kakhulu ukugcwalisa okushisayo ukuvimbela ukonakala kwebhodlela, kuyilapho ibhodlela elingenakristali lisetshenziselwa izinga lokushisa elijwayelekile noma ukugcwaliswa kwezinga lokushisa eliphansi.Ikristalu imhlophe, isiza ibhodlela ukuthi imelane nezinga lokushisa elifinyelela ku-100℃.Ukuqinisekisa ukuthi i-bottleneck engeyona ikristalu ayilinyazwa ukushisa, ubukhulu bayo bodonga ngokuvamile bukhulu kune-frer.Ububanzi bangaphakathi bebhodlela lebhodlela elingacwebezeli bucishe bube buncane ngo-0.25mm, nakuba ububanzi bawo bangaphandle buseduze.
Kwesinye isikhathi, ibhodlela le-non-crystallized lisetshenziselwa ukugcwalisa okushisayo, kodwa buza okuningi emshinini wokugcwalisa.
Amabhodlela e-PET agcwalisa ngokushisayo ikakhulukazi akhiqizwa ngezindlela - ukuvunguza isinyathelo esisodwa kanye nokuvunguza okuzinyathelo ezimbili.
Ngokuvuthela okuzinyathelo ezimbili, vuthela ama-preforms abe yi-1.5 ~ 2 izikhathi zevolumu yamabhodlela okugcina, bese uwashwabanisa ngemva kokushisisa aze afike ku-200 ℃, ukuze ukhuphule izinga lokucwebezela kwebhodlela.Okwesithathu, zivuthele ngendlela enqunywe kusengaphambili ezibunjeni ezingaba ngu-100 ℃, Ekugcineni, faka umoya ngokushesha ukuze ulolonge amabhodlela.Inzuzo yale nqubo izinga le-crystallization yebhodlela liphezulu njenge-45%, futhi ibhodlela lingakwazi ukumelana nokushisa okungaphezulu kuka-95 ℃;Kodwa-ke, okubi kuyimishini eyisiza enkulu, futhi kubiza kakhulu ukuthola amandla okushisa aphezulu.
Isinyathelo esisodwa ukushaya ama-preforms ekubunjweni ku-80 ~ 160 ℃.Gcoba amabhodlela ngokwelula, bese ujova umoya ukuze ulolonge amabhodlela.Le nqubo ilula uma kuqhathaniswa.Ibhodlela lingacwebezelwa ngesithando somlilo esicwebezelayo, noma kuncishiswe ukujiya kwebhodlela.Izinzuzo zayo zidinga kuphela izisetshenziswa ezisizayo ezimbalwa, futhi zibiza kancane ngamandla okushisa.Ngesikhathi esifanayo, ingashintshwa ngomshini ojwayelekile we-PET ibhodlela.Ububi amabhodlela akwazi ukumelana 85 ~ 90 ℃ kuphela.
Njengengxenye ye-Rimzer Group, singochwepheshe ekufakweni kwamabhodlela.Imikhiqizo yethu ihlukaniswe yaba izigaba ezine.Ama-seal liner, ama-PET Preforms, Izesekeli Zezigubhu namakani e-Aluminium.
Silawula ikhwalithi ngokukhiqiza okujwayelekile, kodwa sinikezela ngemikhiqizo ngokwenza ngokwezifiso.
Uzothola isixazululo esisodwa sokumisa emabhodleleni apakishwe eTaizhou Rimzer.
Izixazululo ziqala ekulaleleni izidingo zakho, ukucwaninga ngokuthambekela kokumaketha, ubuchwepheshe obuchwepheshile, kanye nokuthuthukisa okungakhathali.
