Ngokuphuhla koluntu, imfuno yeemveliso zeplastiki kubomi bemihla ngemihla bePeople's Daily iyanda, njengeengxowa zeplastiki, iitreyi zeplastiki, iibhokisi zesidlo sasemini zeplastiki njalo njalo. Okwangoku, ukunyuka kweshishini lokuhambisa ukutya kuye kwandisa imfuno yeemveliso zeplastiki. Imfuno ikwanefuthe elikhulu kwindalo esingqongileyo, kuba iimveliso zeplastiki ziyingozi kakhulu kwindalo esingqongileyo.
Ngenxa yeengxaki ezikhulayo zokusingqongileyo, ukufuna ezinye iindlela endaweni yeplastiki kuye kwaba yinto eqhelekileyo kwihlabathi liphela. Emva kophando oluqhubekayo kunye nophuculo, iimveliso ze-PLA ziye zangena kancinci kwinqanaba lembali. Iimveliso ze-PLA zinomsebenzi wokuwohloka, onokuwohloka ngokupheleleyo kwiintsuku ezingama-90 kubushushu obufanelekileyo kunye nokusingqongileyo. Kwangaxeshanye, ikwanobomi benkonzo ende, igcinwe kakuhle, itreyi ye-PLA kunye nesikhongozeli se-PLA kunye nezinye iimveliso zinokugcinwa ixesha elingaphezu konyaka omnye.
Izinto ezintsha zePLA ezinobuhlobo nokusingqongileyo Iitreyi kunye nezikhongozeli ezinokubola zokupakisha ukutya kwenyama yeziqhamo
I-Poly (i-lactic acid) izinzile kakuhle kubushushu, iqondo lobushushu lokucubungula liyi-170 ~ 230℃, iyakwazi ukumelana ne-solvent, ingacutshungulwa ngeendlela ezahlukeneyo, ezinje ngokuphuma kwi-extrusion, ukujikelezisa, ukolula i-biaxial, ukubumba i-injection blow. Ukongeza ekubeni yi-biobolitable, iimveliso ze-polylactic acid ziyakwazi ukumelana ne-biocompatibility, i-gloss, i-transparent, i-hand feel kunye ne-heat resistance.
I-Polylactic acid (PLA) yinto entsha ebolayo eyenziwe ngestatshi ephuma kwizityalo ezihlaziyekayo ezifana nombona. I-glucose ifunyenwe kwistatshi ngokuyisusa, yaza i-lactic acid enobunyulu obuphezulu yavundiswa kwi-glucose kunye neentlobo ezithile, yaza i-polylactic acid enobunzima obuthile be-molecular yenziwa ngokwenziwa kweekhemikhali. Inokonakala okuhle kwe-biogradation, kwaye inokonakala ngokupheleleyo ziintsholongwane kwindalo emva kokusetyenziswa, kwaye ekugqibeleni ivelise i-carbon dioxide namanzi. Ayingcolisi indalo, nto leyo eluncedo kakhulu ekukhuseleni indalo, kwaye ibonwa njengezinto ezinobuhlobo nokusingqongileyo. Indlela eqhelekileyo yonyango lweplastiki isatshiswa, nto leyo ebangela inani elikhulu legesi ye-greenhouse ekhutshwa emoyeni, ngelixa iplastiki ye-POLylactic acid ingcwatyelwa ekuwohlokeni komhlaba, i-carbon dioxide ngqo kwi-organic matter yomhlaba okanye ifunxwe zizityalo, ayizukukhutshwa emoyeni, ayizukubangela i-greenhouse effect.
I-Poly (lactic acid) inenzuzo ekhethekileyo kwicandelo lezixhobo ezilahlwayo, izinto zokupakisha ukutya kunye nezinye iimveliso ezilahlwayo kuba ayinabungozi kwaphela emzimbeni womntu. Inokubola ngokupheleleyo kwaye ihlangabezane neemfuno eziphezulu zehlabathi, ngakumbi i-European Union, i-United States kunye ne-Japan zokukhusela okusingqongileyo. Ukongeza, emva kophuhliso lwetekhnoloji, imakethi iguqulwe zizixhobo ze-PLA, ezinokoyisa ngempumelelo ukusilela kwesuntswana lokuqala, kwaye ezinye zide zikwazi ukumelana nobushushu ukuya kuthi ga kwi-120℃, zingasetyenziswa njengezixhobo ze-oven ye-microwave.
Nangona kunjalo, ngokwemarike yangoku, ukugquma kobushushu kunye nokukwazi ukutsha kweemveliso zePLA akunakulinganiswa nezinye iimveliso ezibolayo, kodwa ixabiso leemveliso zePLA liphezulu kunezinye iimveliso ezibolayo. Abantu abaninzi bakhetha i-bagasse njengemveliso ebolayo, kodwa i-bagasse ifunxa ioyile, ifunxa amanzi, kwaye ichaphazela iimveliso ezipakishiweyo. Kwakhona iipallet ze-bagasse zinokuba ngundo ukuba azomi ngokwaneleyo.
