Lesi sihloko sidingida ubunkimbinkimbi benoveli yethuI-rPET granulating line, isixazululo esiklanyelwe ngokukhethekile ukuthuthukisa ukusebenza kahle kanye nekhwalithi yokukhiqizwa kabusha kwe-PET pellet.
Yomisa futhi Ucwebezelise esinyathelweni esisodwa, Ukuvula Ukusebenza kahle:
Ubuchwepheshe bethu bokuguquguquka buqeda isidingo sezigaba ezihlukene zokomisa kanye nekristalu, ukwenza kube lula inqubo kanye nokunciphisa ukusetshenziswa kwamandla. Le ndlela yesinyathelo esisodwa ifinyelela umswakama wokugcina ongaphansi kuka-30ppm phakathi nemizuzu engu-20, ukwehlisa kakhulu izindleko zamandla (0.06-0.08kwh/kg) uma kuqhathaniswa nezindlela zendabuko. Ngaphezu kwalokho, ukuminyana kwe-flake kukhuphuka ngo-15-20%, okuthuthukisa ukusebenza kokuphakelayo kwe-extruder.
Ukugcina i-Viscosity yangaphakathi, Ukugcina Ikhwalithi:
Ukomiswa kwe-infrared pre-drying kudlala indima ebalulekile ekugcineni i-intrinsic viscosity (IV) ye-rPET, into ebalulekile ekusetshenzisweni kwebanga lokudla. Ngokunciphisa ukuchayeka kwe-PET emanzini ngesikhathi sokukhipha, ukuwohloka kwe-IV kunomkhawulo, okuqinisekisa ikhwalithi nokusetshenziswa kabusha kwe-resin. Ukwengeza, izikhathi ezimfushane zokumisa (imizuzu engu-15-20) zivimbela ukuphuzi kwemicu yokuncibilika, ukugcina ubuhle bomkhiqizo.
Okukhiphayo Okwengeziwe, Ukusebenza Okuthuthukisiwe:
Ngokushisisa kuqala ama-flakes, isistimu ye-IRD inciphisa ukucindezelwa kokugunda ngaphakathi kwe-extruder, ivumela izinga lokushisa elihlala njalo futhi yenze kube lula isivinini sokukhipha okuphezulu. Lokhu kuhumushela ekwenyukeni okumangalisayo kwamandla omugqa wokukhiqiza, kuze kufike ku-50% kwezinye izimo. Ukwengeza, ukusebenza okuthuthukisiwe kokuphakelayo kanye nokuncishiswa kwe-viscosity okuncishisiwe kunomthelela enqubweni yokukhiqiza ezinzile futhi ebikezelwe.
Ukusebenza Okwenziwe Lula, Izindleko Ezincishisiwe:
Lo mugqa we-rPET granulating unomklamo osebenziseka kalula nomsebenzi olula. Ifakwe uhlelo lwe-Siemens PLC olunokhiye owodwa wokukhumbula, ulayini usiza ukuqalisa okusheshayo nokuvala shaqa okusheshayo, kuqede isidingo sokushisisa kwangaphambili. Usayizi ohlangene kanye nokugcinwa kalula kuthuthukisa ukusebenza kahle komsebenzi.
Izinzuzo Ngokubuka nje:
Izindleko zokukhiqiza ezincishisiwe: Kufika ku-60% ukusetshenziswa kwamandla angaphansi uma kuqhathaniswa nezinhlelo zokomisa zendabuko.
Ukuqalisa okusheshayo nokuvala shaqa ngokushesha: Asikho isidingo sokushisisa kwangaphambili.
Ukusebenza okwenziwe lula: Isinyathelo esisodwa sokumisa & crystallization, uhlelo lwe-Siemens PLC olusebenziseka kalula.
Ukwanda komthamo wokukhiqiza: Ukukhuphuka okungafika ku-50%.
Ikhwalithi yomkhiqizo ethuthukisiwe: I-viscosity yangaphakathi elondoloziwe, ukuphuzi okuncishisiwe.
Compact futhi kulula ukuyinakekela.
Ukutshala imali Kukusasa Lokukhiqiza kwe-rPET:
Lo mugqa wokuqamba kabusha we-rPET umele intuthuko enkulu emkhakheni wokugaywa kabusha kwamapulasitiki. Ngokunikeza ukusebenza kahle okuphakeme, ikhwalithi yomkhiqizo ethuthukisiwe, kanye nokunciphisa ukusetshenziswa kwamandla, kunikeza abakhiqizi amandla okufeza izinhloso zabo zokusimama ngenkathi behlala bencintisana emakethe. Lobu buchwepheshe buvula indlela yekusasa elisimeme kakhulu lemboni yepulasitiki, ithuthukisa umnotho oyindilinga futhi ibambe iqhaza ekwenzeni iplanethi ehlanzekile.
