"Ukuphila kwekhabhoni ephansi" sekuphenduke isihloko esivamile enkathini entsha. Eminyakeni yamuva nje, ukuvikelwa kwemvelo okuluhlaza, ukongiwa kwamandla, kanye nokunciphisa ukungcola kuye kwangena kancane kancane embonweni womphakathi, futhi sekuphenduke umkhuba omusha okhuthazwayo noya ngokuya udumile emphakathini. Esikhathini esiluhlaza kanye nekhabhoni ephansi, ukusetshenziswa kwemikhiqizo ebolayo kubhekwa njengophawu olubalulekile lokuphila okunekhabhoni ephansi, futhi kuyahlonishwa futhi kusatshalaliswa kabanzi.
Ngokusheshisa kwejubane lokuphila, amabhokisi esidlo sasemini epulasitiki anegwebu alahlwayo, izikhwama zepulasitiki, izinti, izinkomishi zamanzi nezinye izinto seziyinto yonke ekuphileni. Ngokungafani nephepha, indwangu nezinye izinto, imikhiqizo yepulasitiki ilahlwa emvelweni futhi kunzima ukucekelwa phansi. Nakuba kulethe ukunethezeka ezimpilweni zabantu, ukusetshenziswa ngokweqile kungadala “ukungcoliswa okumhlophe”. Kulo mongo, kuye kwavela ama-biomaterials angaboli. Izinto ezibolayo eziphilayo ziyinto evelayo enezinzuzo ezibalulekile mayelana nokusebenza kwemvelo uma kuqhathaniswa nemikhiqizo yepulasitiki elahlwayo evamile. Imikhiqizo ekhiqizwa kusetshenziswa ama-biomaterials angaboli njengezinto zokusetshenziswa inendawo enkulu yemakethe futhi iba umthwali obalulekile womqondo wemfashini wendlela yokuphila yekhabhoni ephansi.
Kunezinhlobo eziningi zezinto ezibolayo, okuhlanganisaI-PCL, PBS, PBAT, PBSA, PHA,I-PLGA, i-PLA, njll. Namuhla sizogxila ezintweni ezisafufusa ezingaboli kahle ze-PLA.
I-PLA, obeye aziwe njengoi-polylactic acidd, I-CAS 26023-30-3iyisitashi sezinto ezingavuthiwe ezivutshelwayo ukuze kukhiqizwe i-lactic acid, ebuye iguqulelwe ibe yi-polylactic acid ngokuhlanganiswa kwamakhemikhali futhi ibe nokubola okuhle kwe-biodegradability. Ngemva kokusetshenziswa, ingonakaliswa ngokuphelele ama-microorganisms emvelweni, ekugcineni ikhiqize i-carbon dioxide namanzi ngaphandle kokungcolisa imvelo. Imvelo ivuma kakhulu, futhi i-PLA ibonwa njengento evumelana nemvelo enezakhiwo ezinhle kakhulu zebhayoloji.
Izinto zokusetshenziswa eziyinhloko ze-PLA imicu yezitshalo evuselelekayo, ummbila neminye imikhiqizo yezolimo neseceleni, futhi i-PLA iyigatsha elibalulekile lezinto ezisafufusa ezingaboli. I-PLA inezinto eziyingqayizivele mayelana nobulukhuni nokucaca. Ine-biocompatibility eqinile, ububanzi bohlelo lokusebenza, izakhiwo eziqinile zomzimba nezomshini, futhi ihlangabezana nezidingo ezihlukahlukene zokusetshenziswa. Ingasetshenziswa ngezindlela ezihlukahlukene zokukhiqiza ngezinga elikhulu, ngezinga le-antibacterial lika-99.9%, okwenza kube yimpahla ethembisa kakhulu eyonakalisayo.
I-Polylactic acid (PLA)kuyinto entsha evumelana nemvelo futhi eluhlaza okonakalisayo ekhiqizwa nge-lactic acid njengempahla eluhlaza; Eminyakeni yamuva nje, i-PLA iye yasetshenziswa emikhiqizweni nasezinkundleni ezinjengotshani, i-tableware, izinto zokupakisha zefilimu, imicu, izindwangu, izinto zokunyathelisa ze-3D, njll. I-PLA iphinde ibe namandla amakhulu okuthuthuka emikhakheni efana nemishini yokusiza yezokwelapha, izingxenye zezimoto, ezolimo. , ezamahlathi, nokuvikelwa kwemvelo.
I-PLA ekhiqizwa nguUnilong Industryiwukugcina kuwo wonke "izinhlayiyana" ze-polylactic acid. Ngokukhetha okuqinile kwezinto zokusetshenziswa zekhwalithi ephezulu ze-polylactic acid, ipulasitiki ye-PLA polylactic acid kanye ne-PLA polylactic acid fiber isetshenziselwa ukukhiqiza izisetshenziswa zepulasitiki ezinempilo, ezinobungane, ezisezingeni eliphezulu, neziqinile ezilwa namagciwane. Imikhiqizo yayo eyinhloko ihlanganisa izingubo zasemfashinini, izicathulo nezigqoko, izinto zetafula, izinkomishi namaketela, izinto zokubhala, amathoyizi, izindwangu zasekhaya, izingubo ezisivalayo namabhulukwe, impahla yasendlini, izinto zokugeza ezomile nezimanzi, nezinye izinkambu ezihlobene kakhulu nempilo yethu yansuku zonke.
Ukuvela kweI-PLAingasiza abantu ukuthi baqhelelane nokungcola okumhlophe, inciphise umonakalo wepulasitiki, futhi ikhuthaze ukufezeka okuphelele kwe-carbon peak nokungathathi hlangothi kwe-carbon. Inhloso ye-Unilong Industry "iwukuhambisana nejubane lezikhathi, ukuphila impilo evumelana nemvelo", ukukhuthaza ngamandla imikhiqizo ebolayo, ukwenza abantu badle ukudla okunempilo futhi baphile impilo enempilo, ukuvumela ukuwohloka kwemvelo kungene ezinkulungwaneni zemizi, kuhole umkhuba omusha impilo eluhlaza kanye nekhabhoni ephansi, futhi ungene ngokuphelele empilweni enekhabhoni ephansi.
