Ukunakekelwa kwezempilo okuluhlaza kuyinkomba ebalulekile yentuthuko namuhla, kanye nokuvela kweI-PLA engaboli kahle (i-polylactic acid) izindwangu eziphothayo ezingalukiweinikeza amathuba amasha okunciphisa ukucindezela kwemvelo okubangelwa udoti wezokwelapha.
Izicelo zezokwelapha ze-PLAT spunbond fabric
Indwangu ye-PLA spunbond ibonise amandla emikhakheni eminingi yomkhiqizo wezokwelapha ngenxa yezimpawu zayo:
Imishini yokuzivikela: Indwangu ye-PLA ye-spunbond ingasetshenziswa ukwenza izingubo zokuhlinza, ama-drapes okuhlinzwa, izikhwama zokubulala amagciwane, njll. Ucwaningo luphinde lwakha i-PLA based SMS (spunbond meltblown spunbond) izinto zokwakha, ezingasetshenziselwa imishini yokuvikela yezokwelapha edinga ukusebenza kahle kokuhlunga.
Imikhiqizo elwa namagciwane: Ngokungeza ama-antibacterial agents angaphili njenge-nano zinc oxide (ZnO) ku-PLA, izindwangu ezingalukiwe ezinezindawo zokulwa namagciwane ezihlala isikhathi eside neziphephile zingalungiswa. Isibonelo, uma okuqukethwe kwe-ZnO kungu-1.5%, izinga lokulwa namagciwane ngokumelene ne-Escherichia coli ne-Staphylococcus aureus lingafinyelela ngaphezu kwama-98%. Lolu hlobo lomkhiqizo lungasetshenziswa ezikhathini ezinezidingo eziphezulu ze-antibacterial, njengezingubo zokwelashwa, amashidi ombhede alahlwayo, njll.
Ukupakishwa kwezokwelapha namalayini wezinsimbi: Indwangu engalukiwe ye-PLA ingasetshenziselwa ukupakisha izikhwama zamathuluzi ezokwelapha. Ukuphefumula kwayo okuhle kuvumela amagesi okubulala inzalo njenge-ethylene oxide ukuba angene, kuyilapho kuvimbela ngempumelelo ama-microorganisms. I-PLA nanofiber membrane ingasetshenziselwa izinto zokuhlunga eziphezulu.
Izinzuzo zemvelo nezinselele
Izinzuzo ezibalulekile zemvelo: Ukusetshenziswa kwendwangu ye-PLA spunbond kusiza ukunciphisa ukusetshenziswa kwemithombo ye-petroleum ngemikhiqizo yezokwelapha elahlwayo. Ngemva kokulahlwa, ingakwazi ukubola ngokuphelele ngaphansi kwezimo zokwenziwa komquba, ibambe iqhaza ekusakazweni kwemvelo, futhi isize ukunciphisa ukugcinwa kwemvelo kanye “nokungcola okumhlophe” kwemfucuza yezokwelapha.
Izinselele okubhekene nazo: Ukukhuthazwa kwendwangu ye-PLA spunbond emkhakheni wezokwelapha kusabhekene nezinselele ezithile. Isibonelo, izinto ezihlanzekile ze-PLA zinezinkinga ezifana ne-hydrophobicity eqinile, ukuthungwa kwe-brittle, futhi zidinga ukuthuthukisa ukumelana nokushisa. Kodwa-ke, lezi zinkinga zilungiswa kancane kancane ngokuguqulwa kwezinto kanye nokuthuthukiswa kwenqubo. Ngokulungiselela i-PLA copolymer fibers, ukumuncwa kwawo umswakama kanye nokumelana nokushisa kungathuthukiswa. Ukuhlanganisa i-PLA namanye ama-biopolymers afana ne-PHBV kuphinde kwafakazelwa ukuthi kuyindlela ephumelelayo yokuthuthukisa izici zayo zokusebenzisa nokusebenza kwayo.
Isiqondiso sentuthuko yesikhathi esizayo
Ukuthuthukiswa kwesikhathi esizayo kwendwangu ye-PLA spunbond emkhakheni wezokwelapha kungase kube nokuthambekela okulandelayo:
Ukuguqulwa kwezinto kuyaqhubeka nokujula: Ngokuzayo, ucwaningo luzoqhubeka nokuthuthukisa izici zendwangu ye-spunbond ye-PLA ngokusebenzisa i-copolymerization, ukuhlanganisa, nokwengeza izithasiselo (ezifana nokusebenzisa izandiso zamaketango nama-antioxidants ukuze kuthuthukiswe ukucutshungulwa kwe-PLA), njengokuthuthukisa ukuguquguquka kwayo, ukuphefumula, nokungena komswakama, ukuze ihlangabezane nezimfuneko eziphakeme zezinhlelo zokusebenza zezokwelapha.
I-Industrial synergy kanye nokukhuthazwa kobuchwepheshe: Ukuthuthukiswa okuqhubekayo kweIndwangu ye-PLA spunbondithembele ekuhlanganisweni eduze kwezimboni, izifundiswa, kanye nocwaningo ukuze kuthuthukiswe impumelelo kubuchwepheshe obubalulekile kanye nokwanda kwesikali sezezimboni. Lokhu kuhlanganisa nokuthuthukisa ukuncibilika kokuncibilika kwama-copolyester e-PLA kanye nokuthuthukisa ubuchwepheshe bokukhiqiza obuqhubekayo bezimboni bezinhlaka ze-SMS ezisekelwe ku-PLA.
Ukuqhutshwa kabili kokusekelwa kwenqubomgomo kanye nesidingo semakethe: Ngokukhishwa "kwezinhlelo zokuvinjelwa kwepulasitiki" e-Hainan nakwezinye izifunda, kanye nokugcizelelwa komhlaba wonke ekuthuthukisweni okusimeme kanye nomnotho oyindilinga, izinqubomgomo ezifanele zezemvelo zizoqhubeka nokudala indawo yemakethe ebanzi yezinto zokwakha ezibolayo.
Isifinyezo
Indwangu ye-spunbond ye-PLA eyonakaliswayo, nezinzuzo zayo zokuvikela indawo eluhlaza okotshani, izinto zokusetshenziswa ezivuselelekayo, ukubola kwezinto eziphilayo, namandla okusebenza, inikeza ukukhetha okusha kwemboni yezokwelapha ukuze kuncishiswe umthwalo wemvelo futhi kulindeleke ukuthi ingenise inkathi yokuvikelwa kwemvelo kwemikhiqizo yezokwelapha elahlwayo.
Nakuba ukuthuthukiswa okuqhubekayo kusadingeka ekusebenzeni kwempahla nokulawulwa kwezindleko, ngokuthuthuka kobuchwepheshe, ukuvuthwa kwemboni, kanye nokukhuthazwa kwezinqubomgomo zemvelo, amathemba okusetshenziswa kwendwangu ye-PLA spunbond emkhakheni wezokwelapha athembisa kakhulu.
Ngethemba ukuthi ulwazi olungenhla lungakusiza uqonde kangcono indwangu ye-PLA spunbond. Uma unentshisekelo eyengeziwe ezinhlotsheni ezithile zemikhiqizo yezokwelapha ye-PLA, njengezingubo ezivikelayo ezisezingeni eliphezulu noma izindwangu ezithile ezilwa namagciwane, singaqhubeka nokuhlola.
I-Dongguan Liansheng Non woven Technology Co., Ltd.yasungulwa ngoMeyi 2020. Kuyibhizinisi elikhulu lokukhiqiza indwangu engalukiwe ehlanganisa ucwaningo nentuthuko, ukukhiqiza, nokudayiswa. Ingakhiqiza imibala ehlukahlukene ye-PP spunbond yezindwangu ezingalukiwe ezinobubanzi obungaphansi kwamamitha angu-3.2 ukusuka ku-9 amagremu kuya ku-300 amagremu.
