Namhlanje, ingxaki yeplastiki inzulu kwihlabathi liphela. Ngomjikelo owongezelekayo we-biosphere, iplastiki eyenziwe ngabantu iya kubuyela ebantwini. Ke zeziphi izinto ezinokuthi zithathe indawo yeplastikhi ngokufanelekileyo? Lowo uthotywa lula ngokulula ukwakulungele ngakumbi ukuwuthwala. Andibhekiseli kwilaphu eliqhelekileyo kunye nezinye izinto.
Okwangoku ayikho.
1. Iiplastikhi zangoku ezinokuthotywa zithathwa njengobuqhetseba:
Ezinye zibandakanya izithako ezifana nesitashi kunye necalcium carbonate kwi-polyethylene yemveli ukunciphisa inani le-polyethylene. Oku kucekeceka kukucekiseka okupheleleyo.
Iplastikhi yenyani ehlaziyiweyo emelwe yi-polylactic acid inokuthotywa ngaphantsi kwe-5% phantsi kweemeko zendalo zokulahla inkunkuma. Ukuthotywa isidima kufuna i-hydrolysis eyomeleleyo yoshishino okanye ukubila kobushushu obuphezulu. Ngapha koko, izinto ezibonakalayo ze-polylactic acid kukutya, kunye nokuveliswa kweplastikhi kukutya kukodwa kuyinkunkuma enkulu. Ixabiso le-polylactic acid nalo libiza kakhulu xa kuthelekiswa neeplastikhi zemveli.
Isiseko songcoliseko lweplastiki kukuba zonke iimveliso zeplastiki zinokubuyiselwa kwinkqubo yokulahla inkunkuma ukuze itshiswe okanye ilahlwe ngokutsha okanye iphinde isetyenziswe. Akunantsingiselo ukuba iimveliso zeplastiki ezisezidolophini zihlise umgangatho, kwaye uninzi lweemveliso zeplastiki ezisezidolophini zinokubuyiselwa kwinkqubo yokulahla inkunkuma. Iifilimu ze-mulch zezolimo (ezihlala ziguga kwaye zaphuke emhlabeni iminyaka emi-2 ngaphambi kokuba zilahlwe) kunye nezicoci zeplastikhi zesepha zezona zinto zibangela ungcoliseko lweplastiki. Andifuni ukusombulula eyona ngxaki iphambili, kodwa jonga ukungqubana kwesibini kwaye ubethe ibhodi. Oku kuyafana neqela leBai Zuo eliqhuba i-jet yacht yabucala enemoto enkulu yokufuduka kwiNkomfa yoKhuselo lwezeNdalo.
Ukuthotywa kwenkunkuma ngokwawo asiyondlela ifanelekileyo yokulahla iiplastikhi. Ukulahlwa ngokuchanekileyo kweeplastikhi kukusombulula ingxaki yokutshiswa okungenabungozi kwimeko yokuxuba okufanelekileyo. Kanye ngokuxoxa ngokuthotywa kwecermet, i-enamel, iglasi kunye neemveliso zamatye zihlekisa kwaphela.
2. Njengesixhobo esisetyenziswa ngokuxhaphakileyo, ixabiso / ubunzima / ukusebenza bodwa kweeplastikhi akukho zinto zingena endaweni yazo.
Impahla yendalo iyabiza kakhulu kwaye kusafuneka ifakwe iplastiki okanye ipeyinti ukufezekisa inqanaba leplastiki.
Ukufakwa kwephepha kubi kakhulu. Uninzi lwephepha loqhakamshelwano lokutya elisetyenziswe kwishishini lokutya ligalelwe iplastiki okanye i-wax. Kuba zonke iimveliso zeplastiki zisetyenziswa, kutheni ungasebenzisi zonke iimveliso zeplastiki? Ungcoliseko lwemveliso yamaphepha aluphantsi.
Isinyithi, i-ceramic, i-enamel, iglasi kunye nelitye zinzima kakhulu xa kuthelekiswa neplastiki. Ukufakwa kwe-bamboo kunye nemveliso yeenkuni akwamkelekanga, kwaye ukufunxwa kwe-bamboo kunye neemveliso zeenkuni eziphantsi kunamandla kakhulu ukuhlangabezana neemfuno. Ixabiso le-bamboo eshinyeneyo kunye neemveliso zeenkuni ezinentengiso ebuthathaka zinyukile.
Ingxaki enye ngerabha, irabha yesilicone kunye neplastiki.
3. Izinto ezinokuhlulwa zingahlulwa ngokwamacandelo: izinto ezidityanisiweyo. Izinto ezintathu ezisisiseko: isinyithi, izinto ezingaphiliyo kunye nepolymer. Izinto eziluncedo zeepolymers ubunzima obulula, amandla aphezulu, ukuqhubekeka ngokulula kunye nokwenza izinto elubala. Zeziphi izinto ocinga ukuba zingaphunyezwa?
Iindidi ezininzi zezinto ezibonakalayo azinakutshintshwa ngokulula endaweni yomnye. Ubume bezinto kunye nolwakhiwo lwento ngokusisiseko lubeka ezona zinto ziphambili kwimathiriyeli. Ukusebenza kunokuphuculwa kusetyenziswa iteknoloji yokulungisa izinto.
Ukuthotywa kweepolymers kuyingxaki ngokwenene. Okwangoku, abaphandi basebenza nzima, kodwa inkqubela phambili iyacotha. Kwikamva elibonakalayo, ukusetyenziswa kweeplastikhi kuya kulawulwa kwiindawo apho kungafunekiyo ukusebenzisa iiplastikhi, kodwa akukabikho ndlela yokuzitshintsha kwezinye iindawo eziyimfuneko.
