Ikuzisela ukuqonda okunzulu kweebhegi zokupakisha ezinokubola!
Njengoko amazwe amaninzi evala iingxowa zeplastiki, iingxowa ezingonakaliswa yizinto eziphilayo zisetyenziswa kwimizi-mveliso engakumbi.Ukukhusela okusingqongileyo ngumkhwa ongenakuthintelwa.Ngaba kukho nayiphi na imithombo ecebisa ukuba kusetyenziswe iingxowa zeplastiki ezinokuguquguquka?Zeziphi iimveliso ezinokuthi zisetyenziswe iingxowa zeplastiki ezinokonakala?Ndiyakholelwa ukuba le yeyona nto abathengi abaninzi abaodola iimfuno zeplastiki ezinokuguquguquka ngokupheleleyo bafuna ukwazi.Namhlanje, KULUNGILE Ukupakishwa kwemveliso yeengxowa zeplastiki ezonakeleyo
1. Yintoni ukupakishwa kwe-biodegradable?
Ingxowa yeplastiki enokubola luhlobo lwengxowa yeplastiki enokuthi ithobe ngokupheleleyo amanzi, ikharbon diokside kunye nezinye iimolekyuli ezincinci.Umthombo oyintloko wale nto eyonakalisiweyo yi-polylactic acid (PLA), ekhutshwa kwingqolowa kunye ne-cassava.IPlanethi (PLA) luhlobo olutsha lwemathiriyeli esekwe kwibhayoloji kunye nemathiriyeli ehlaziyekayo enokubola.Emva kokubiliswa kweglucose kunye nezinye iintlobo ukuvelisa ubunyulu obuphezulu be-lactic acid, i-poly (i-lactic acid) enobunzima obuthile bemolekyuli yayidityaniswe yindlela yokudityaniswa kweekhemikhali, kwaye emva koko i-glucose yafunyanwa nge-saccharification.Le mveliso ine-biodegradability efanelekileyo kwaye inokutshatyalaliswa ngokupheleleyo yi-microorganisms yendalo emva kokusetyenziswa ukuvelisa i-carbon dioxide kunye namanzi, engayi kungcolisa imo engqongileyo emva kokusetyenziswa.Iluncedo kakhulu ekukhuselweni kwendalo kwaye ithathwa njengento ehambelana nokusingqongileyo.
Okwangoku, izinto eziphambili zezinto eziphilayo zeengxowa zeplastiki ezichithwayo zenziwe nge-PLA + PBAT, enokuthi ihlanjululwe ngokupheleleyo emanzini kunye ne-carbon dioxide kwiinyanga ezi-3-6 phantsi kwemeko yokuvundisa (i-60-70 degrees).Akukho kungcoliseka kwendalo.Kutheni ukongeza i-PBAT?I-PBAT yi-copolymer ye-adipic acid, i-1, i-4-butanediol kunye ne-terephthalic acid, eyona nto i-biodegradable chemically synthesized aliphatic kunye ne-polymer enuka kamnandi.I-PBAT inokuguquguquka okugqwesileyo kwaye ingasetyenziselwa ukukhutshwa kwefilimu, ukubunjwa kokuvuthela, ukugquma kwe-extrusion kunye nezinye iinkqubo zokubumba.Ukudibanisa kwe-PLA kunye ne-PBAT yenzelwe ukuphucula ukuqina, ukubola kwe-biodegradability kunye nokwakheka kwe-PLA.
2. Baphi abenzi beengxowa ze-biodegradable ezinegama elihle?
Kwintsimi yeengxowa zeplastiki ezinokubola, yenze umatshini okhethekileyo wokuvuthela ifilimu, umatshini wokushicilela, umatshini wokusika ingxowa, inkunkuma yokuphinda isetyenziswe kwigranulator kunye nemigca eyahlukeneyo yokuvelisa eqolileyo yeengxowa zeplastiki ezibolisiweyo.Iimveliso zigquma iibhegi zevest, iibhegi zenkunkuma, iibhegi zezandla, iibhegi zempahla, iibhegi zehardware, iibhegi zokuthambisa, iibhegi zokutya, iibhegi zentloko zekhadi, i-kraft paper / iingxowa ezihlanganisiweyo ze-PLA, njl., umgangatho ozinzile, ukusebenza kakuhle kwemveliso, ushicilelo olugqibeleleyo, ubungqina bokufuma. , ubungqina bokugqobhoza, okungeyotyhefu, ukutywinwa kakuhle, ukolula okulungileyo, ukuthungwa okulungileyo, ukukhuselwa kwendalo.
ukupakishwa Ok ebambelele ingqikelelo ukhuselo lokusingqongileyo kwaye uzibophelele kuphuhliso oluzinzileyo lwemekobume yendalo, uphuhliswe ngempumelelo ifanelekile kushishino lokupakisha kunye nokubonelela ukutya izinto ngokupheleleyo biodegradable kunye neemveliso, unamava atyebileyo kwishishini lokupakisha nokusabela kuhlelo lwenkunkuma, ukukhuthaza ukusetyenziswa kwakhona kobutyebi, kunye nokuphuhlisa ngokukhutheleyo iimveliso ezinokuboliswa ngokupheleleyo kwibakala lokutya.
3. Zeziphi iimveliso ekunokuthi kusetyenziswe kuzo iingxowa ezinokonakala?
Iingxowa zeplastiki ezibolisiweyo zisetyenziswa kakhulu kwihempe, ukunitha, iimpahla, iimpahla, amalaphu, ukutya, ihardware, i-electronics, izinto zokuthambisa kunye namanye amashishini.Iingxowa zeplastiki ezibolisiweyo zineendlela ezininzi zokutywina, ezifana nethambo lokuncamathelisa, iziphu, iteyiphu, njl.Ngoku, iingxowa zeplastiki ze-biodegradable zingena kuzo zonke iindlela zobomi, kwaye kukho iindlela ezahlukeneyo;Kwixesha elizayo, iingxowa zeplastiki ezibolisiweyo ziya kuba yimveliso epheleleyo yoshishino lokupakisha.
