“Ukuphila impilo ephansi kwekhabhoni” sekuyinto evame kakhulu enkathini entsha. Eminyakeni yamuva nje, ukuvikelwa kwemvelo eluhlaza, ukulondolozwa kwamandla, kanye nokunciphisa ukukhishwa kwegesi kuye kwangena kancane kancane embonweni womphakathi, futhi kuye kwaba yindlela entsha ekhuthazwayo futhi ethandwa kakhulu emphakathini. Enkathini eluhlaza kanye nephansi kwekhabhoni, ukusetshenziswa kwemikhiqizo ebolayo kubhekwa njengophawu olubalulekile lokuphila kwekhabhoni ephansi, futhi kuhlonishwa kakhulu futhi kusatshalaliswa kabanzi.
Ngokusheshisa kwejubane lempilo, amabhokisi esidlo sasemini epulasitiki alahlwayo, izikhwama zepulasitiki, izinti, izinkomishi zamanzi nezinye izinto seziye zaba khona yonke indawo empilweni. Ngokungafani nephepha, indwangu nezinye izinto, imikhiqizo yepulasitiki ilahlwa ngokwemvelo futhi kunzima ukuyilimaza. Nakuba iletha lula empilweni yabantu, ukusetshenziswa ngokweqile kungabangela "ukungcola okumhlophe". Kulesi simo, kuye kwavela izinto eziphilayo ezibolayo. Izinto eziphilayo ziyinto evelayo enezinzuzo ezibalulekile maqondana nokusebenza kwemvelo uma kuqhathaniswa nemikhiqizo yepulasitiki yendabuko elahlwayo. Imikhiqizo ekhiqizwa kusetshenziswa izinto eziphilayo ezibolayo njengezinto zokusetshenziswa inendawo enkulu yemakethe futhi iba ngumthwali obalulekile womqondo wendlela yokuphila yemfashini ephansi kwekhabhoni.
Kunezinhlobo eziningi zezinto ezibolayo, okuhlanganisaI-PCL, i-PBS, i-PBAT, i-PBSA, i-PHA,I-PLGA, PLA, njll. Namuhla sizogxila ezintweni ezibolayo ezivelayo ze-PLA.
I-PLA, obeye aziwe njengoi-polylactic acid, I-CAS 26023-30-3iyinto eluhlaza yesitashi evutshelwa ukukhiqiza i-lactic acid, eguqulwa ibe yi-polylactic acid ngokwenziwa kwamakhemikhali futhi ibe nokubola okuhle. Ngemva kokusetshenziswa, ingabola ngokuphelele yizinto ezincane zemvelo, ekugcineni ikhiqize i-carbon dioxide namanzi ngaphandle kokungcolisa imvelo. Imvelo inhle kakhulu, futhi i-PLA ibhekwa njengento enobungani nemvelo enezakhiwo ezinhle kakhulu zebhayoloji.
Izinto eziyinhloko zokusetshenziswa ze-PLA yizintambo zezitshalo ezivuselelekayo, ummbila kanye neminye imikhiqizo yezolimo kanye neyaseceleni, kanti i-PLA iyigatsha elibalulekile lezinto ezibolayo ezisafufusa. I-PLA inezakhiwo ezihlukile ngokwezinto ezibolayo kanye nokucaca. Ihambisana kahle nezinto eziphilayo, ububanzi bokusetshenziswa, izakhiwo eziqinile zomzimba nezemishini, futhi ihlangabezana nezidingo ezahlukene zokusetshenziswa. Ingasetshenziswa ngezindlela ezahlukene zokukhiqiza ngezinga elikhulu, ngesilinganiso sokulwa namagciwane esingu-99.9%, okwenza kube yinto ebolayo ethembisayo kakhulu.
I-polylactic acid (i-PLA)kuyinto entsha enobungani nemvelo futhi eluhlaza ebolayo ekhiqizwa nge-lactic acid njengezinto zokusetshenziswa; Eminyakeni yamuva nje, i-PLA isetshenziswe emikhiqizweni nasezindaweni ezifana notshani, izitsha zokudla, izinto zokupakisha amafilimu, imicu, izindwangu, izinto zokunyathelisa ze-3D, njll. I-PLA inamandla amakhulu okuthuthukiswa emikhakheni efana nemishini yokusiza yezokwelapha, izingxenye zezimoto, ezolimo, amahlathi, kanye nokuvikelwa kwemvelo.
I-PLA ekhiqizwe yi-Imboni ye-Unilongiyona engcono kakhulu kuzo zonke "izinhlayiya" ze-polylactic acid. Ngokukhetha okuqinile kwezinto zokusetshenziswa ze-polylactic acid ezisezingeni eliphezulu, i-PLA polylactic acid plastic kanye ne-PLA polylactic acid fiber zisetshenziselwa ukukhiqiza izinto ezisekela ipulasitiki ezinempilo, ezinobungani nesikhumba, ezisezingeni eliphezulu, neziqinile ezilwa namagciwane. Imikhiqizo yayo eyinhloko ifaka phakathi izingubo zesimanje, izicathulo nezigqoko, izitsha zokudla, izinkomishi nama-kettle, izinto zokubhala, amathoyizi, izindwangu zasekhaya, izingubo namabhulukwe ahambisanayo, izimpahla zasekhaya, ama-wipes omile namanzi, kanye neminye imikhakha ehlobene kakhulu nokuphila kwethu kwansuku zonke.
Ukuvela kweI-PLAkungasiza abantu ukuthi bagweme ukungcola okumhlophe, kunciphise umonakalo wepulasitiki, futhi kukhuthaze ukufezeka okuphelele kwe-carbon peak kanye nokungathathi hlangothi kwe-carbon. Inhloso ye-Unilong Industry "ukuhambisana nesivinini sesikhathi, ukuphila impilo enobungani nemvelo", ukukhuthaza ngamandla imikhiqizo ebolayo, ukwenza abantu badle impilo enempilo futhi baphile impilo enempilo, ukuvumela ukubola kwe-biogradation kungene emindenini eyizinkulungwane, kuhole umkhuba omusha wokuphila okuluhlaza kanye nokuphila okune-carbon low, kanye nokungena ngokuphelele empilweni yokuphila okune-carbon low.
