Emkhakheni wokugaywa kabusha kwepulasitiki, ukuze uphishekele izinto ezigaywe kabusha zekhwalithi ephezulu, izinto ezigaywe kabusha ze-PET zidinga ukuthuthukiswa zibe sezingeni elilingana nokusebenza kwe-PET eluhlaza. Phakathi kwamapulasitiki ahlukahlukene, i-polyethylene terephthalate (PET) isetshenziswa kabanzi emkhakheni wokupakisha, ikakhulukazi ukuma emaphaketheni esiphuzo sebhodlela. Nokho, ukuze kuthuthukiswe ukusebenza kwezinto ezigaywe kabusha ze-PET zibe sezingeni eliqhathaniswa nele-PET yomdabu, kudingeka ubuchwepheshe obuthuthukisiwe, okuwumshini okhulisa i-viscosity we-PET IV.

Ivelu ye-IV ipharamitha eyinhloko yokulinganisa inqwaba yamangqamuzana e-PET, ebonisa ubude beketango le-polymer futhi ihlobene ngokuqondile nezakhiwo zemishini ezifana namandla, ukuqina, nokucutshungulwa. I-PET yomdabu ngokuvamile inenani eliphezulu le-IV, ngaleyo ndlela inokuqina okuhle kakhulu nokuba sobala. Nokho, phakathi nenqubo yokugaywa kabusha, inani le-IV lezingcezu ze-PET ngokuvamile liyehla ngenxa yokuwohloka kokushisa nokwemishini ekucutshungulweni kwangaphambilini.
Umshini okhulayo we-IV usetshenziselwa ukukhulisa i-viscosity yezinhlayiya ezigaywe kabusha, okuvumela okubalulekile kwe-PET ukuthi kuhlanganiswe kabusha-kumikhiqizo yekhwalithi ephezulu.

Umshini okhulayo we-PET ophinde wagaywa kabusha ama-flakes IV uwumshini okhethekile wokugaywa kabusha osetshenziselwa ukukhulisa inqwaba yamangqamuzana e-PET avuselelwe kabusha. Lobu buchwepheshe buvamise ukusebenzisa inqubo eqinile-yesimo se-polymerization (SSP), lapho ama-PET flakes agaywe kabusha ashiselwa abe ngaphansi kwendawo yawo yokuncibilika endaweni elawulwayo (ngokuvamile i-nitrogen noma i-vacuum) ukuze kuthuthukiswe ukunwetshwa noma ukuhlanganiswa kabusha kwamaketango e-polymer ngaphandle kokuncibilikisa ama-flakes.
Le nqubo isiza ukulungisa umonakalo wamaketanga e-polymer anqwabelene ezigabeni zokuqala zokucubungula ngokuxosha imikhiqizo eguquguqukayo kanye nokufeza ukusabela kweketanga okwakha kabusha inqwaba yamangqamuzana. Ngakho-ke, ama-PET flakes agaywe kabusha ane-IV ephezulu, icrystallinity engcono, kanye nezakhiwo ezingcono zokusebenza.

1. Thuthukisa ikhwalithi yomkhiqizo
Ukwenyusa ama-PET avuselelwe kabusha ama-flakes IV kungathuthukisa amandla emishini, ukuzinza okushisayo, kanye nokungafihli kwe-PET egaywe kabusha, kuyenze ifanelekele izinhlelo zokusebenza ezinzima ezifana namabhodlela ebanga lokudla nokupakishwa kwezimboni.
2. Umthelela wemvelo
Ngokuthuthukisa ikhwalithi yamashidi agaywe kabusha e-PET, ukuncika ku-PET eluhlaza kwehlisiwe, izinsiza ze-fossil zilondoloziwe, futhi ukukhishwa kwegesi ebamba ukushisa ehlobene nokukhiqizwa kwepulasitiki entsha kwehlisiwe.
3. Inani eliphakeme lezomnotho
Izinto ze-PET ezigaywe kabusha ezine-IV ephezulu zingathola amanani emakethe angcono futhi zivule izimakethe ezinenzuzo eyengeziwe, njengokukhiqiza i-polyester fiber kanye nokubumba umjovo, ngaleyo ndlela kwandise inzuzo yezindawo zokugaywa kabusha.

Iqhutshwa intuthuko esimeme kanye nezingcindezi zokulawula, imboni yokuvuselela kabusha i-PET ikhula ngokushesha. Ukuhlanganisa i-IV ekhulayo kanye ne-PET yokuchoboza, yokuhlanza, kanye nemigqa yokukhiqiza i-granulation emgqeni owodwa ukuze kuncishiswe izindleko zezinto zokusetshenziswa ze-PET, ukuthuthukisa ikhwalithi yezinto ze-PET ezigaywe kabusha, futhi kusheshise ukushintshela emnothweni wepulasitiki oyindilinga.
Umshini okhulayo we-PET flakes IV uyintuthuko ebalulekile embonini yokugaywa kabusha kwe-PET. Ngokubuyisela ama-polymer owonakele eduze nekhwalithi yawo yasekuqaleni, kwenza abakhiqizi bakwazi ukukhiqiza imikhiqizo yepulasitiki esimeme ngaphandle kokubeka engcupheni ukusebenza. Ngokukhula kwesidingo somhlaba wonke se-PET egaywe kabusha, ukutshala imali kubuchwepheshe obukhulayo be-IV akuyona nje into ehlakaniphile, kodwa futhi kubalulekile ekwakheni ikusasa eliluhlaza neliyisiyingi.

Amashadi ashisayo: i-pet flakes iv umshini okhulayo we-viscosity, i-China pet flakes iv viscosity ikhulisa abakhiqizi bemishini, abahlinzeki, imboni
