Ngokuqhubeka kwenkqubela phambili kweteknoloji yokuvelisa amalaphu, iifayibha ezintsha ziye zaba zizinto ezisetyenziswayo zelaphu. Namhlanje, ndiza kukwazisa kakhulu ngeteknoloji yokuchonga ifayibha yepolyester ephinde yasetyenziswa.
Kuyaqondakala ukuba kwixesha elidlulileyo, ngenxa yokungabikho kweendlela zokuhlola kunye nokungakwazi kwee-arhente zokuvavanya ukukhupha iingxelo ezisemgangathweni, amashishini ayengenakukwazi ukonwabela imigaqo-nkqubo yesizwe efanelekileyo, kwaye kwangaxeshanye abangela ukudideka ekubhalweni kweelebhile kwezinye iimveliso zepolyester.
Yintoni ifayibha ye-polyester ephinda isetyenziswe (i-PET)?
Oko kukuthi, izinto zelaphu ze-polyester (PET) polymer kunye ne-polyester (PET) textile ziyaphinda zisetyenziswe kwaye zicutshungulwe zibe yi-polyethylene terephthalate fiber.
Ngokwesiqhelo, ifayibha yepolyester ephinda isetyenziswe (ebizwa ngokuba yipolyester ephinde yasetyenziswa) ibhekisa kwipolyester ephinde yasetyenziswa (ezifana neebhotile ezirhabaxa, ifoam, isilika elahlekileyo, i-waste pulp, i-waste textile, njl.njl.) eyenziwe ngeenkqubo zokuphinda isetyenziswe. Ifayibha ye-Ester.
Umgaqo Wokuchonga
Ngokusekelwe kumahluko obalulekileyo phakathi kwenkqubo yokucubungula i-polyester ephinde yasetyenziswa kunye ne-polyester eyi-virgin, ekhokelela kwiimpawu ezahlukeneyo, isampuli icutshungulwa ngokweemeko ezichaziweyo kwaye ivavanywe kwi-chromatograph yolwelo esebenza kakuhle. Ngokuphathelele umahluko kwindawo yencopho yesampuli phantsi kwamaxesha ahlukeneyo okugcinwa, Ukufezekisa injongo yokuchonga umgangatho.
Inyathelo lokuchongwa
1. I-Methanolysis
2. Ukudumba-Ukutsalwa
3. Ukufunyanwa kwe-chromatography yolwelo olusebenza kakuhle
Ulwelo olucocwayo olucutshungulwe apha ngasentla 1 kunye no-2 lufunyanwa ngobuninzi be-chromatography yolwelo.
4. Ukusetyenzwa kwedatha kunye nokuchonga
I-polyester ephinda isetyenziswe iya kubangela utshintsho kumxholo kunye nokusasazwa kwee-macromolecular heterogeneous chain links kunye ne-oligomers ngexesha lenkqubo yokulungiselela, ezingasetyenziswa njengesiseko sokuchongwa kwe-polyester ephinde yasetyenziswa kunye ne-virgin polyester.
Ulwazi oluthe ngqo malunga nendawo ende kunye nolwazi oluchaza incopho luboniswe kwitheyibhile engezantsi.

Jonga kwixesha elizayo
Ngenxa yokwanda kokusetyenziswa kwe-polyester kunye nolwazi lwabantu ngokukhuselwa kwendalo, kuqwalaselwa ngakumbi ekusetyenzisweni kwakhona kwenkunkuma ye-polyester. Ukusetyenziswa kwenkunkuma ye-polyester ukuvelisa i-polyester fiber ephinde yasetyenziswa kunokunciphisa iindleko, kunciphise ukusetyenziswa kweoyile, kwaye kuphucule iingenelo zoqoqosho, nto leyo ebaluleke kakhulu kuphuhliso oluzinzileyo lweshishini le-chemical fiber.
Kwangaxeshanye, ngokonyuka kwenani le-polyester ephinde yasetyenziswa, umba wokutshintshwa kwe-polyester ephinde yasetyenziswa kunye ne-polyester eyi-virgin uye watsala ingqalelo engakumbi kwishishini. Ixabiso lale mibini likwabonisa ulwalamano oluhle, kwaye ukubonwa komahluko phakathi kwezi zimbini iTekhnoloji ifumana ingqalelo engakumbi.
