Itiye elifakwe esikhwameni selithuthuke ngokushesha ngenxa yezinzuzo zalo “zobuningi, inhlanzeko, ukunethezeka, kanye nesivinini”, futhi imakethe yetiye egcwele izikhwama zomhlaba wonke ikhombisa ukukhula ngokushesha.
Njengento yokupakisha izikhwama zetiye,iphepha lokuhlunga itiyeakufanele nje kuqinisekiswe ukuthi izithako ezisebenzayo zetiye zingasakazeka ngokushesha esobho setiye ngesikhathi sokupheka, kodwa futhi zivimbele i-tea powder esikhwameni ekungeneni kwesobho setiye. Ngemva kweminyaka yokuthuthuka, izinto zephepha lokuhlunga itiye ziye zashintsha kancane kancane zisuka ku-gauze, iphepha lokuhlunga, inayiloni, i-PET, i-PVC, i-PP nezinye izinto zokwakha ummbila.
I-corn fiber, eyaziwa nangokuthi i-polylactic acid (PLA) fiber, itholakala ezinsizeni zezitshalo ezivuselelekayo ezifana nommbila, amazambane, notshani bezitshalo. Ine-biocompatibility enhle kanye ne-biodegradability, izakhiwo ze-antibacterial, kanye nokuphefumula. Angeke isetshenziselwe ukwenza izikhwama zetiye ezingalukiwe ezibolayo, kodwa futhi isetshenziswe emkhakheni wokwenza amaphepha omanzi ukukhiqiza iphepha lokupakisha ukudla njengezikhwama zetiye, izikhwama zekhofi, kanyeiphepha lokuhlunga.
Ngakho-ke, ngokugxila ezicini zokusebenza zempahla ngokwayo, yiziphi izinzuzo eziyinhloko zokusebenzisa i-PLA fiber ekwenzeni iphepha elimanzi?
1. Impahla ingokwemvelo futhi ingahlangana nokudla
Impahla eluhlaza ye-polylactic acid fiber ivela ezinsizeni zezitshalo ezivuselelekayo. Njengempahla eqinisekisiwe yokuphepha kokudla, i-polylactic acid fiber ingasetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zokudla, kwezemithi, nakwezinye izinhlelo zokusebenza zephepha zasendlini ezifunwa kakhulu. Ukuthatha ukusetshenziswa kwezikhwama zetiye kanye nephepha lokuhlunga ikhofi njengesibonelo, ukuzifaka ngqo emanzini ashisayo ngaphandle kwemvula yepulasitiki noma ezinye izinto eziyingozi kuwubungane kakhulu emzimbeni womuntu.
2. Ukubola kwezinto eziphilayo
Uma sithatha ukusetshenziswa kwezikhwama zetiye njengesibonelo, inani elikhulu lezikhwama zetiye ezilahlwayo zisetshenziswa emhlabeni wonke nsuku zonke. Izikhwama zetiye ezenziwe ngezinto zendabuko zinomjikelezo omude kakhulu wokuwohloka, ozoletha ingcindezi enkulu ku-ecology yemvelo. Kodwa-ke, izikhwama zetiye noma eminye imikhiqizo eyenziwe ngezinto ze-polylactic acid inokubola okuhle kakhulu kwe-biodegradability.
Imikhiqizo yendwangu engalukiwe ye-Polylactic acid ingaboliswa ngokuphelele ibe yikhabhoni dioxide namanzi yizinambuzane ezincane endaweni yemvelo enamazinga okushisa athile kanye nomswakama, njengesihlabathi, udaka, namanzi olwandle. Imfucuza yomkhiqizo we-Polylactic acid ingabola ngokuphelele ibe yi-carbon dioxide namanzi ngaphansi kwezimo zokwenziwa komquba wezimboni (izinga lokushisa elingu-58 ℃, umswakama 98%, nezimo ze-microbial) izinyanga ezingu-3-6; Ukugcwaliswa komhlaba ezindaweni ezijwayelekile nakho kungafinyelela ukuwohloka kungakapheli iminyaka emi-3-5.
3. Ingaxutshwa ne-pulp yokhuni noma eminye imicu yemvelo ukuze isetshenziswe
Imicu ye-polylactic acid ivame ukuxutshwa ngesilinganiso esithile nemicu ye-pulp yokhuni, ama-nanofibers, njll. ukwenza i-pulp nephepha. I-Polylactic acid ngokuyinhloko idlala indima ekubopheni nasekuqiniseni, ngokuxhuma eminye imicu ngokushisa nezinga lokushisa ukuze kuzuzwe injongo yokufaka uhlaka nokuqinisa. Ngaphezu kwalokho, ngokulungisa isilinganiso se-slurry kanye nendlela yokucubungula, ingahlangabezana nezidingo ezihlukene zezimo ezahlukene.
4. Ukuhlanganiswa kwe-Ultrasonic okushisayo kungafinyelelwa
Ngokusebenzisa imicu ye-polylactic acid ukwenza i-pulp nephepha, i-ultrasonic thermal bonding ingafinyelelwa ekukhiqizeni okulandelayo, okungagcini nje ngokusindisa umsebenzi futhi kunciphise izindleko, kodwa futhi kuthuthukisa ukusebenza kahle kokukhiqiza.
5. Ukusebenza kokuhlunga
Iphepha lokuhlunga itiye elenziwe nge-polylactic acid fiber linokusebenza okuhle kokuhlunga namandla aphezulu okumanzi, okungagcina ngempumelelo amaqabunga etiye nezinye izinhlayiya eziqinile, kuyilapho kuvumela ukunambitheka nephunga letiye ukuthi lingene ngokugcwele.
Ngaphezu kwephepha lokuhlunga itiye, i-polylactic acid fiber ingasetshenziswa futhi ephepheni lokuhlunga lemithi yamaShayina yendabuko, iphepha lesihlungi sekhofi, kanye namanye amaphepha okupakisha ukudla.
