Iplastiki, imveliso enkulu kwinkulungwane yama-20, ukubonakala kwayo kuye kwakhuthaza inkqubela-phambili yoshishino nokutshintsha ubomi babantu;iplastiki, ukuveliswa okubi kwinkulungwane ye-20, ungcoliseko lwayo kunye nemiphumo emibi yendalo ayikasonjululwa - izibonelelo zeplastiki kunye ne-Didvantage ifana "nekrele elintlangothi-mbini" ebomini bokwenene, inamandla ngokwaneleyo. , kodwa kuyingozi kakhulu.Kwaye kuthi, ixabiso eliphantsi, ukuzinza kwe-thermal, amandla oomatshini, ukuqhubekeka kunye nokuhambelana kweeplastiki kwenza kube nzima ngathi ukuba singayisebenzisi ngokupheleleyo kwimveliso yeemveliso zethu, nto leyo ekhokelela ekubeni nangona siyaqonda ukuba iiplastiki zinokusongela okusingqongileyo. , kodwa kusafuneka sithembele kulo mbandela.Kwakhona kungenxa yesi sizathu ukuba "ukuvalwa" okanye "ukutshintsha" iiplastiki kuye kwaba ngumxholo wexesha elide kwinkalo yesayensi yezinto zokukhusela indalo.
Enyanisweni, le nkqubo ayikho ngaphandle kweziphumo.Ixesha elide, uphando malunga "nokutshintsha iiplastiki" luye lwaqhubeka luqhubela phambili, kwaye iziphumo ezininzi ezithembekileyo nezisebenzayo ziye zavela emva komnye, njengeeplastiki ze-polylactic acid.Kwaye kutshanje, iqela lophando elivela kwiSikolo seSayensi esiSiseko kwi-Swiss Federal Institute of Technology eLausanne liye laphuhlisa iplastiki eyenziwe nge-biomass efana ne-polyethylene terephthalate (PET).Esi sixhobo sitsha sineenzuzo zeeplastiki zemveli ezifana nokuzinza okuqinileyo kwe-thermal, amandla athembekileyo oomatshini, kunye neplastiki eqinile.Kwangaxeshanye, inkqubo yemveliso ikwanobuhlobo kakhulu nokusingqongileyo.Kuxelwe ukuba izinto ezintsha ze-PET zeplastiki zisebenzisa i-glyoxylic acid yokulungiswa kweplastiki, ekulula ukuyisebenzisa, kodwa inokuguqula i-25% yenkunkuma yezolimo okanye i-95% yeswekile ecocekileyo ibe yiplastiki.Ukongeza ekubeni kulula ukuvelisa, le mpahla nayo iyakwazi ukuthotywa ngenxa yesakhiwo sayo seswekile.
Kuyafaneleka ukukhankanya ukuba okwangoku, abaphandi baye basebenza ngempumelelo le nto kwiimveliso zeplastiki eziqhelekileyo ezifana neefilimu zokupakisha, kwaye babonise ukuba inokusetyenziswa njenge-3D yoshicilelo olusetyenziswayo (oko kukuthi, lunokwenziwa kwiifilaments zokuprintwa kwe-3D. ), ke sinesizathu sokulindela ukuba le mathiriyeli ibe neemeko ezibanzi zosetyenziso kwixesha elizayo.
Ukuqukumbela: Uphuhliso lwemathiriyeli yeplastiki yinkqubo yokusombulula ungcoliseko lweplastiki ukusuka kumthombo wokhuseleko lokusingqongileyo.Nangona kunjalo, kwimbono yabantu abaqhelekileyo, ngokwenene, impembelelo yolu phuhliso kuthi ngakumbi ukuba izixhobo eziqhelekileyo ebomini ziqala ukutshintsha.Ngokwahlukileyo, ukuqala kubomi bethu, ukuba sifuna ngokwenene ukusombulula ungcoliseko lweplastiki ukusuka kumthombo, mhlawumbi kubaluleke ngakumbi, ukuphepha ukusetyenziswa kakubi kunye nokulahlwa kweeplastiki, ukomeleza ulawulo lokuphinda usetyenziswe kunye nokulawulwa kweemarike, kunye nokuthintela ukungcola ukugeleza kwindalo.
