"Ukuphila kwekhabhoni ephantsi" kuye kwaba ngumxholo oqhelekileyo kwixesha elitsha. Kwiminyaka yakutshanje, ukukhuselwa kokusingqongileyo okuluhlaza, ugcino lwamandla, kunye nokunciphisa ukukhutshwa kwezinto ezikhutshwayo kuye kwangena ngokuthe ngcembe kumbono woluntu, kwaye kuye kwaba yindlela entsha ekhuthazwayo neyandayo eluntwini. Ngexesha eliluhlaza kunye nekhabhoni ephantsi, ukusetyenziswa kweemveliso ze-biodegradable kuthathwa njengophawu olubalulekileyo lobomi bekhabhoni ephantsi, kwaye ihlonishwa ngokubanzi kwaye isasazwa.
Ngokukhawuleza kwesantya sobomi, iibhokisi zesidlo sasemini zeplastiki ezilahlwayo, iingxowa zeplastiki, izinti, iikomityi zamanzi kunye nezinye izinto ziye zaxhaphaka ebomini. Ngokungafaniyo nephepha, ilaphu kunye nezinye izinto, iimveliso zeplastiki zilahlwa kwindalo kwaye kunzima ukuthotywa. Ngelixa kuzisa uncedo kubomi babantu, ukusetyenziswa ngokugqithisileyo kunokubangela “ungcoliseko olumhlophe”. Kulo mongo, kuye kwavela ii-biomaterials eziguquguqukayo. Izinto eziguquguqukayo ze-Biodegradable zizinto ezivelayo ezinenzuzo ebalulekileyo malunga nokusebenza kokusingqongileyo xa kuthelekiswa neemveliso zeplastiki ezilahlwayo. Iimveliso ezenziwe kusetyenziswa i-biomaterials ye-biodegradable njengezinto ezikrwada zinendawo enkulu yentengiso kwaye ziba ngumthwali obalulekileyo wendlela yokuphila enefashoni ephantsi kwekhabhoni.
Kukho iintlobo ezininzi zezinto eziphilayo, kuqukaI-PCL, PBS, PBAT, PBSA, PHA,I-PLGA, i-PLA, njl. Namhlanje siza kugxininisa kwizinto ezikhulayo ze-biodegradable PLA.
I-PLA, kwaziwa njengepolylactic acid, I-CAS 26023-30-3sistatshi ekrwada imathiriyeli evundisiweyo ukuvelisa iasidi lactic, ethi ke iguqulelwe kwi asidi polylactic ngokusebenzisa imichiza synthesis kwaye biodegradability elungileyo. Emva kokusetyenziswa, inokutshatyalaliswa ngokupheleleyo yi-microorganisms kwindalo, ekugqibeleni ivelise i-carbon dioxide kunye namanzi ngaphandle kokungcolisa indalo. Imo engqongileyo ithandeka kakhulu, kwaye i-PLA yamkelwa njengesixhobo esihambelana nokusingqongileyo kunye neempawu ezibalaseleyo zebhayoloji.
Ezona zixhobo ziphambili ze-PLA ziintsinga zezityalo ezivuselelwayo, umbona kunye nezinye iimveliso zezolimo kunye ne-sideline, kwaye i-PLA lisebe elibalulekileyo lezinto ezikhulayo ezikhulayo ze-biodegradable. I-PLA ineempawu ezizodwa malunga nokuqina kunye nokungafihli. Ine-biocompatibility eyomeleleyo, uluhlu olubanzi lwesicelo, iipropathi ezinamandla zomzimba kunye nezoomatshini, kwaye ihlangabezana neemfuno ezahlukeneyo zokusetyenziswa. Ingasetyenziselwa kwiindlela ezahlukeneyo zemveliso enkulu, kunye nesantya sokulwa ne-antibacterial ye-99.9%, okwenza kube yinto ethembisayo enokuchithwa.
I-Polylactic acid (PLA)sisixhobo esitsha esinobuhlobo nokusingqongileyo kunye nohlaza olunokonakala oluveliswe kwiasidi ye-lactic njengezinto ezikrwada; Kwiminyaka yakutshanje, i-PLA isetyenziswe kwiimveliso kunye neenkalo ezifana neendiza, i-tableware, izinto zokupakisha ifilimu, iifayili, amalaphu, izinto zokushicilela ze-3D, njl njl. , amahlathi, kunye nokukhuselwa kwendalo.
I-PLA eveliswe nguIshishini elingapheliyoyeyona nto iphambili kuyo yonke i-polylactic acid "isuntswana". Ngokukhetha ngokungqongqo izinto ezikumgangatho ophezulu zepolylactic acid ekrwada, iplastiki ye-PLA polylactic acid kunye ne-PLA polylactic acid fiber zisetyenziselwa ukuvelisa izinto eziphilileyo, ezinobuhlobo eluswini, ezikumgangatho ophezulu, kunye nezixhobo zeplastiki ezichasene ne-antibacterial. Iimveliso zayo eziphambili zibandakanya impahla esefashonini, izihlangu kunye neminqwazi, izinto zetafile, iikomityi neeketile, izinto zokubhala, iithoyi, amalaphu asekhaya, iimpahla ezivalayo kunye neebhulukhwe ezivalayo, iimpahla zasekhaya, izinto zosula ezomileyo nezimanzi, kunye namanye amasimi asondelelene nobomi bethu bemihla ngemihla.
Ukuvela kweI-PLAinokunceda abantu bahlale kude nokungcola okumhlophe, ukunciphisa umonakalo weplastiki, kunye nokukhuthaza ukufezekiswa okugqibeleleyo kwe-carbon peak kunye nokungathathi hlangothi kwekhabhoni. Injongo yoShishino lwase-Unilong “kukuhambisana nesantya samaxesha, ukuphila ubomi obunobuhlobo nokusingqongileyo”, ngamandla ukukhuthaza iimveliso ezinokonakala, ukwenza abantu batye ukutya okusempilweni kwaye baphile ubomi obusempilweni, ukuvumela ukonakaliswa kwebhayoloji kungene kumawakawaka emizi, ikhokele indlela entsha yokufumana ubutyebi. ubomi obuluhlaza kunye nekhabhoni ephantsi, kwaye ngokubanzi ungene kubomi bekhabhoni ephantsi.
