Ithini lesiphuzo le-PET elithengiswa ngobuningi elinokuphela okulula ukulivula
Inqubo yokukhiqiza yeIthini lesiphuzo se-PETkuwuhlelo lokusebenza olujwayelekile, olunezinyathelo eziningi oluhlanganisa ukulungiswa kwezinto, ukubumba, ukuqeda, kanye nokulawula ikhwalithi. Ngezansi kunencazelo eningiliziwe, yesinyathelo ngesinyathelo, okuhlanganisa ubuchwepheshe obubalulekile kanye nezindawo zokuhlola ikhwalithi ezenzelwe izinhlelo zokupakisha iziphuzo:
| Isigaba Sokukhiqiza | Izinqubo Eziyinhloko | Imininingwane Yobuchwepheshe Nezidingo Zekhwalithi | Inhloso |
| 1. Ukulungiswa Kwezinto Ezingavuthiwe | -Ukukhetha izinto nokomisa-Ukuxuba okuhlanganisiwe (ongakukhetha) | -I-resin ye-PET eyi-Virgin: Ama-pellets asezingeni lokudla ahambisana nezindinganiso ze-FDA/EFSA (awekho ama-BPA, ama-phthalates).ukuhlanganiswa kwe-rPET: Hlanganisa ama-PET pellet asetshenziswe kabusha (okuqukethwe okungu-30–100%) ne-PET eyi-virgin ukuze uhlale uphilile; qinisekisa ukuthi i-rPET ihlanzwa ngokwezinga lokudla.Ukomisa: Ama-pet pellets omisiwe ku-120–160°C amahora angu-4–6 ukuze kuncishiswe okuqukethwe umswakama ngaphansi kuka-0.02% (kuvimbela ukwakheka kwamabhamuza ngesikhathi sokubumba).Izithasiselo (ongakukhetha): Hlanganisa iziqinisi ze-UV (zeziphuzo ezizwela ukukhanya) noma ama-masterbatches anombala (wamathini angacacile) zibe ama-pellet. | Susa amaphutha abangelwa umswakama; qinisekisa ukuphepha kwezinto kanye nokuvumelana kokuxhumana kokudla. |
| 2. Ukubumba Umjovo Wangaphambi Kokwenza | -Ukubumba ngomjovo we-PET preforms-Ukupholisa nokunciphisa | -Inqubo: Ama-PET pellets omisiwe ayancibilikiswa ku-260–280°C emshinini wokubumba umjovo, bese efakwa ezikhumbeni ze-preform (i-preform iwumkhiqizo omncane, oqediwe kancane, omise okwe-test tube onentamo enentambo).-Izikhunta: Izikhunta ezinembile ezinezinombolo zesikhala ezihambisana nomthamo wokukhiqiza (isb., izikhunta ezingama-96-cavity zokukhiqiza okuphezulu).-Ukupholisa: Ama-preform apholiswa ngokushesha (imizuzwana eyi-10-20) ngamanzi abandayo ukuze kulondolozwe ukuqina kwesimo.Ukusika: Susa i-flash eyengeziwe entanyeni yangaphambi kokwakheka ukuqinisekisa ukuthi usayizi wentambo uyafana. | Khiqiza ama-preform ahambisanayo—isisekelo se-PET singabumba futhi siqine. |
| 3. Ukubumba Kokunwebeka Kokunwebeka (Isinyathelo Esiyinhloko) | -Ukushisa kwangaphambilini-Ukubumba kwe-Swear & Blow-Ukupholisa kokugcina | -Ukushisa: Ama-preform afudunyezwa ku-90–110°C (izinga lokushisa lokushintsha kwengilazi le-PET) kuhhavini we-infrared; indawo yentamo ivikelwe ekushiseni ukuze kulondolozwe ubuqotho bentambo.Nweba: Induku yokwelula isunduza i-preform efudumele iqonde phezulu ibe ubude bayo bokuqala obuphindwe kabili kuya kathathu (ithuthukisa ukuqondiswa kwama-molecule ukuze kube namandla).Ukubumba nge-blow: Umoya ocindezelwe kakhulu (20–40 bar) uyafakwa ukuze kwandiswe i-preform enwetshiwe ngokumelene nomgodi wesikhunta sethini, kwakhiwe isimo sethini sokugcina (esiyisilinda, esinciphile, noma esenziwe ngokwezifiso).-Ukupholisa: Isikhunta sipholiswa ngamanzi ukuze siqinise ithini le-PET ngemizuzwana emi-2-5. | Yakha umzimba wokugcina wekhani le-PET ngobukhulu obuqondile, ukumelana nengcindezi, kanye nokucaca. |
| 4. Ukucubungula Kwesibili Nokuqedela | -Ukusika nokususa amabala-Ukwelashwa kwendawo (ongakukhetha)-Ukuphrinta nokulebula-Ukuhlanganiswa kwesivalo | -Ukusika: Sika unqenqema olungaphezulu lwethini lube ukuphakama okufanayo ukuze kufakwe isivalo.Ukwelashwa kwendawoUkwelashwa kwe-corona (kwandisa ukucindezeleka kobuso) ukuqinisekisa ukunamathela kweyinki ekuphrintiweni; noma ukufaka i-matte/i-frosted coating yemikhiqizo yekhwalithi ephezulu.UkuphrintaSebenzisa uyinki ophephile ekudleni, ongelapheka nge-UV ukuthola imidwebo ecacile, ama-logo, kanye nolwazi lokuhambisana nemithetho (isb., amalebula angasetshenziswa kabusha, umbhalo wezilimi eziningi).Ukuhlanganiswa kwesivalo: Namathisela iziphetho ezivuleka kalula (i-EOE) noma izivalo zesikulufu ezingaphinde zivalwe—qinisekisa ukuthi uvala umoya ukuze kuhlangatshezwane nezidingo zesikhathi sokuphelelwa yisikhathi kwesiphuzo. | Thuthukisa ubuhle, uphawu, kanye nokusebenza; qinisekisa ukuthi ithini selikulungele ukugcwaliswa. |
| 5. Ukulawulwa Kwekhwalithi Nokuhlolwa | -Ukuhlolwa kobukhulu-Ukuhlolwa kokumelana nokucindezela-Ukuhlolwa kokuvuza-Ukuhlolwa kokuphepha kokudla | -Ukuhlola ubukhulu: Qinisekisa ukuphakama kwethini, ububanzi, kanye nobukhulu bodonga (ukubekezelelana ± 0.1mm) ngama-gauge azenzakalelayo.-Ukuhlolwa kwengcindezi: Faka amathini kungcindezi yangaphakathi engamabha angu-3–4 (yeziphuzo ezine-carbonated) ukuqinisekisa ukuthi akukho ukuguquka noma ukuqhekeka.Ukuhlolwa kokuvuzaSebenzisa izitholi zokuvuza ze-vacuum noma ze-helium ukuqinisekisa ukungabi nomoya (okubalulekile ekuvuseleleni isiphuzo).Ukuhlolwa kokuphepha kokudla: Hlola ama-monomers asele, izinsimbi ezisindayo, noma ukufuduka kwe-microplastic (thobela imikhawulo ye-FDA/EFSA). | Susa imikhiqizo enezinkinga; qinisekisa ukuthi iyahambisana nezindinganiso zokuphepha kokudla kanye nokupakisha. |
| 6. Ukupakisha Nokugcina Impahla | -Ukuqoqa kanye nokubeka ndawonye-Ukufaka ama-pallet kanye nokugcina | -UkuqoqaAmathini afakwa ezikhwameni zepulasitiki noma emabhokisini ukuze kuvinjelwe ukuklwebheka ngesikhathi sokuthuthwa.Ukufaka i-PalletSebenzisa ama-palletizer azenzakalelayo ukuhlanganisa amabhokisi; songa ama-pallet ngefilimu yokunwebeka ukuze aqine.Isitoreji: Gcina endaweni yokugcina impahla eyomile, epholile (izinga lokushisa elingu-15–25°C, umswakama ongaphansi kuka-60%) ukuze ugweme ukuwohloka kwe-PET. | Lungisa amathini aqediwe ukuze athunyelwe ezindaweni zokugcwalisa iziphuzo; gcina ikhwalithi yomkhiqizo ngaphambi kokusebenzisa. |
