Iasidi yePolylactic (PLA) sisixhobo esitsha seplastiki esinokonakala esenziwe kwisitatshi esithathwe kwimithombo yezityalo ezivuselelekayo ezifana nombona.Ine-biodegradability elungileyo kwaye inokuthotywa ngokupheleleyo yi-microorganisms kwindalo emva kokusetyenziswa, ekugqibeleni ivelise i-carbon dioxide kunye namanzi.Ayingcolisi imo engqongileyo, iluncedo kakhulu ekukhuselweni kwendalo, yamkelwa njengesixhobo sokukhusela indalo esingqongileyo
Kwingxowa yeplastiki enokubola izinto ekrwada, i-polylactic acid (i-PLA) yaziwa njengenye yeendidi ezinesakhono sophuhliso, kunye ne-biocompatibility, i-biodegradability kunye nesakhono sokuvuselela izixhobo.Kwimeko yendalo, inkunkuma ye-PLA inokuthotywa ibe yi-CO2 kunye ne-H2O ngoluhlu lweenkqubo ze-biological metabolic ezifana ne-hydrolysis (iinyanga ezi-6-12).Le CO2 kunye ne-H2O ingasetyenziselwa izityalo ukuvelisa isitashi ngexesha le-photosynthesis, engasetyenziselwa ukuvelisa i-polylactic acid kwakhona.Ngoko ke, i-Polylactic acid ayiyona nje into engapheliyo, kodwa inokunciphisa ukungcola okumhlophe, igcine izixhobo zeoli, kwaye yinto enokugcina "i-carbon cycle balance" kwindalo.
Ixesha elichanekileyo elithathwayo ukuba ingxowa esetyenzisiweyo enokubola iphinde ibole ixhomekeke kwizinto ezahlukeneyo, ezifana nobushushu kunye nobungakanani bokufuma.Iingxowa ezivundisiweyo zinokonakala kwisithuba seentsuku ezingama-30 kwiindawo zokuthengisa umgquba kwaye zingaphelanga iintsuku ezingama-90 kwiinkqubo zokwenziwa komgquba ekhaya.
Okwangoku sivelisa: iibhegi zekofu ezibolayo, iibhegi zeti ezibolayo.Iingxowa zeBiodegradable ezineflethi, ibhegi yebhayoloji esecaleni etywiniweyo, ibhegi yokupakishwa kokutya enokubola, ibhegi ye-zipper enokubola, i-3-side enokubola njalo njalo, iimveliso zethu zithengisa kumazwe angaphezu kwama-20 kwihlabathi liphela, zininzi iimeko kunye neesampulu, ukuba unayo. imfuno yeengxowa biodegradable, nceda uqhagamshelane nathi, siya kukunika ezona zisombululo ukupakishwa, Vumela iimveliso zakho ukuba ukuthengisa ngcono.Kwaye usebenze kunye nathi ukukhusela umhlaba.
