“Ukuphila ubomi obuphantsi kwekhabhoni” kube ngumxholo ophambili kwixesha elitsha. Kwiminyaka yakutshanje, ukhuseleko lokusingqongileyo oluluhlaza, ukugcinwa kwamandla, kunye nokunciphisa ukukhutshwa komoya kuye kwangena kancinci kancinci kumbono woluntu, kwaye kuye kwaba yindlela entsha ekhuthazwayo nethandwa kakhulu kuluntu. Kwixesha lokusetyenziswa kwekhabhoni eluhlaza kunye nekhabhoni ephantsi, ukusetyenziswa kweemveliso ezinokubola kuthathwa njengophawu olubalulekileyo lobomi obuphantsi kwekhabhoni, kwaye kuhlonitshwa kwaye kusasazwa ngokubanzi.
Ngokukhawuleziswa kwesantya sobomi, iibhokisi zesidlo sasemini zeplastiki ezinefoam ezilahlwayo, iingxowa zeplastiki, izinti zokusika, iikomityi zamanzi kunye nezinye izinto ziye zanda kakhulu ebomini. Ngokungafaniyo nephepha, ilaphu kunye nezinye izinto, iimveliso zeplastiki ziyalahlwa ngokwendalo kwaye kunzima ukuzitshabalalisa. Nangona zizisa lula kubomi babantu, ukusetyenziswa kakhulu kunokubangela "ungcoliseko olumhlophe". Kule meko, kuye kwavela izinto eziphilayo ezibolayo. Izinto eziphilayo zizinto ezivelayo ezineenzuzo ezibalulekileyo ngokubhekiselele ekusebenzeni kokusingqongileyo xa kuthelekiswa neemveliso zeplastiki zemveli ezilahlwayo. Iimveliso ezenziwe kusetyenziswa izinto eziphilayo ezibolayo njengezinto eziluhlaza zinendawo enkulu yemarike kwaye ziba ngumthwali obalulekileyo wengcamango yendlela yokuphila yefashoni esezantsi yekhabhoni.
Kukho iintlobo ezininzi zezinto ezibolayo, kuqukaI-PCL, i-PBS, i-PBAT, i-PBSA, i-PHA,I-PLGA, PLA, njl. Namhlanje siza kugxila kwizinto ezibolayo ezivelayo ze-PLA.
I-PLA, kwaziwa njengei-polylactic acid, I-CAS 26023-30-3sisixhobo esiluhlaza sesitatshi esivundisiweyo ukuvelisa i-lactic acid, ethi emva koko iguqulwe ibe yi-polylactic acid ngokusebenzisa ukwenziwa kweekhemikhali kwaye ibe nokubola kakuhle. Emva kokusetyenziswa, inokonakala ngokupheleleyo ziintsholongwane kwindalo, ekugqibeleni ivelise i-carbon dioxide namanzi ngaphandle kokungcolisa okusingqongileyo. Okusingqongileyo kulungile kakhulu, kwaye i-PLA ibonwa njengesixhobo esinobuhlobo nokusingqongileyo esineempawu ezintle zebhayoloji.
Izinto eziphambili zePLA ziifayibha zezityalo ezivuselelekayo, umbona kunye nezinye iimveliso zezolimo nezecala, kwaye iPLA lisebe elibalulekileyo lezinto ezibolayo neziphumayo. IPLA ineempawu ezikhethekileyo ngokubhekiselele kubulukhuni kunye nokucaca. Ihambelana kakhulu ne-biocompatibility, uluhlu olubanzi lokusetyenziswa, iimpawu ezinamandla zomzimba neze-mechanical, kwaye ihlangabezana neemfuno ezahlukeneyo zokusetyenziswa. Ingasetyenziswa ngeendlela ezahlukeneyo zokuvelisa ubungakanani obukhulu, ngesantya se-antibacterial se-99.9%, nto leyo eyenza ibe yeyona nto ithembisayo ukubola.
I-polylactic acid (PLA)yinto entsha enobuhlobo nokusingqongileyo kwaye iluhlaza ebolileyo eyenziwe nge-lactic acid njengezinto eziluhlaza; Kwiminyaka yakutshanje, i-PLA isetyenzisiwe kwiimveliso nakwiindawo ezifana neestraw, izitya zetafile, izinto zokupakisha ifilimu, iifayibha, amalaphu, izinto zokuprinta ze-3D, njl. I-PLA ikwanawo amandla amakhulu ophuhliso kwiinkalo ezifana nezixhobo zonyango ezincedisayo, iindawo zeemoto, ezolimo, amahlathi, kunye nokukhuselwa kwendalo.
I-PLA iveliswe nguIshishini eliNyeyeyona nto ibalaseleyo kuzo zonke "iinxalenye ze-polylactic acid". Ngokukhetha ngokungqongqo izinto eziluhlaza ze-polylactic acid ezikumgangatho ophezulu, i-PLA polylactic acid plastic kunye ne-PLA polylactic acid fiber zisetyenziselwa ukuvelisa izinto ezisempilweni, ezinobuhlobo nolusu, ezikumgangatho ophezulu, nezinamandla ezisekelwe kwi-antibacterial petroleum. Iimveliso zayo eziphambili ziquka impahla yefashoni, izihlangu kunye neminqwazi, izitya zetafile, iikomityi kunye neeketile, izinto zokubhala, amathoyizi, amalaphu asekhaya, iimpahla kunye neebhulukhwe ezivalayo, izinto zasekhaya, iiwipes ezomileyo nezimanzi, kunye nezinye iindawo ezinxulumene nobomi bethu bemihla ngemihla.
Ukuvela kweI-PLAinokunceda abantu bahlale kude nongcoliseko olumhlophe, inciphise umonakalo weplastiki, kwaye ikhuthaze ukufezekiswa ngokugqibeleleyo kwe-carbon peak kunye nokungathathi cala kwe-carbon. Injongo ye-Unilong Industry "kukuhambisana nesantya samaxesha, ukuphila ubomi obunobuhlobo nokusingqongileyo", ukukhuthaza ngamandla iimveliso ezinokubola, ukwenza abantu batye impilo esempilweni kwaye baphile ubomi obunempilo, ukuvumela ukubola kwe-biogradation kungene kumawaka emizi, kukhokele umkhwa omtsha wobomi obuluhlaza kunye nobo buphantsi kwe-carbon, kwaye kungene ngokupheleleyo kubomi obuphantsi kwe-carbon.
