Ngokuqhubeka kwentuthuko yobuchwepheshe bokukhiqiza izindwangu, imicu emisha eminingi iye yaba izinto zokusetshenziswa zezindwangu. Namuhla, ngizokwethula kakhulu ubuchwepheshe bokuhlonza imicu ye-polyester ephinde yasetshenziswa.
Kuyaqondakala ukuthi esikhathini esidlule, ngenxa yokuntuleka kwezindlela zokuhlola kanye nokungakwazi kwezikhungo zokuhlola ukukhipha imibiko yekhwalithi, amabhizinisi ayengakwazi ukujabulela izinqubomgomo zikazwelonke ezifanele, futhi ngesikhathi esifanayo abangela ukudideka ekulebhelweni kwemikhiqizo ethile ye-polyester.
Iyini i-fiber ye-polyester ephinde yasetshenziswa (i-PET)?
Okusho ukuthi, izinto zendwangu ze-waste polyester (PET) polymer kanye ne-waste polyester (PET) ziyasetshenziswa kabusha futhi zicutshungulwe zibe yi-polyethylene terephthalate fiber.
Ngokwesimo sabantu abavamile, i-polyester fiber ephinde yasetshenziswa (ebizwa ngokuthi i-polyester ephinde yasetshenziswa lapha) ibhekisela ku-polyester ephinde yasetshenziswa (njengezinhlayiya zamabhodlela, i-foam, i-waste silk, i-waste pulp, izindwangu ezingafuneki, njll.) ezenziwe ngezinqubo zokusebenzisa kabusha. I-Ester fiber.
Isimiso Sokuhlonza
Ngokusekelwe kumehluko obalulekile phakathi kwenqubo yokucubungula i-polyester ephinde yasetshenziswa kanye ne-polyester emsulwa, okuholela ezicini ezahlukene, isampula icutshungulwa ngokwezimo ezibekiwe futhi ihlolwe ku-chromatograph yoketshezi esebenza kahle kakhulu. Ngokuya ngomehluko endaweni ephakeme yesampula ngaphansi kwezikhathi ezahlukene zokugcina, Ukufeza injongo yokuhlonza okufanelekile.
Isinyathelo sokuhlonza
1. I-Methanolysis
2. Ukuvuvukala-Ukukhipha
3. Ukutholwa kwe-chromatography yoketshezi esebenza kahle kakhulu
Uketshezi lokwelapha olucutshungulwa ku-1 no-2 okungenhla ngokulandelana luhlolwa nge-chromatography yoketshezi esebenza kahle kakhulu.
4. Ukucutshungulwa kwedatha kanye nokuhlonza
I-polyester ephinde yasetshenziswa izobangela izinguquko kokuqukethwe kanye nokusatshalaliswa kwezixhumanisi zamaketanga ahlukene kanye nama-oligomers ngesikhathi senqubo yokulungiselela, okungasetshenziswa njengesisekelo sokuhlonza i-polyester ephinde yasetshenziswa kanye ne-polyester engeyona eyemvelo.
Ulwazi oluthile lwendawo ephakeme kanye nolwazi lwendawo ephakeme oluyisici luboniswe kuthebula elingezansi.

Bheka esikhathini esizayo
Njengoba ukusetshenziswa kwe-polyester kwanda kanye nokuqwashisa kwabantu ngokuvikelwa kwemvelo, kugxilwa kakhulu ekusetshenzisweni kabusha kwemfucuza ye-polyester. Ukusetshenziswa kwemfucuza ye-polyester ukukhiqiza i-polyester fiber ephinde yasetshenziswa kunganciphisa izindleko, kunciphise ukusetshenziswa kukawoyela, futhi kuthuthukise izinzuzo zomnotho, okubaluleke kakhulu ekuthuthukisweni okusimeme kwemboni ye-fiber yamakhemikhali.
Ngesikhathi esifanayo, ngokwanda kwenani le-polyester ephinde yasetshenziswa, udaba lokushintsha i-polyester ephinde yasetshenziswa kanye ne-polyester engeyona i-virgin luye lwadonsela ukunaka okwengeziwe embonini. Umkhuba wamanani walezi zinto ezimbili ukhombisa nokuhlobana okuthile okuhle, futhi ukutholakala komehluko phakathi kwalezi zinto ezimbili Ubuchwepheshe buthola ukunakwa okwengeziwe.
