Oku kukuzisela ulwazi olunzulu ngeengxowa zokupakisha ezinokubola!
Njengoko amazwe amaninzi evala iingxowa zeplastiki, iingxowa ezinokubola ziyasetyenziswa kumashishini amaninzi. Ukukhusela okusingqongileyo yindlela engenakuphepheka. Ngaba kukho imithombo ecebisa ukusetyenziswa kweengxowa zeplastiki ezinokubola? Zeziphi iimveliso ezinokusetyenziswa kuzo iingxowa zeplastiki ezinokubola? Ndikholelwa ukuba le yinto abathengi abaninzi aba-odola iimfuno zeengxowa zeplastiki ezinokubola ngokupheleleyo abafuna ukuyazi. Namhlanje, OK Ukupakisha imveliso yeengxowa zeplastiki ezinokubola
1. Yintoni ukupakisha okubolayo?
Ingxowa yeplastiki ebolayo luhlobo lwengxowa yeplastiki enokonakalisa amanzi ngokupheleleyo, i-carbon dioxide kunye nezinye iimolekyuli ezincinci. Umthombo ophambili wale nto ibolayo yi-polylactic acid (PLA), ekhutshwa kumbona kunye ne-cassava. I-Planet (PLA) luhlobo olutsha lwezinto ezisekelwe kwi-bio kunye nezinto ezibolayo ezivuselelekayo. Emva kokubiliswa kweglucose kunye nezinye iintlobo ukuvelisa i-lactic acid ecocekileyo kakhulu, i-poly (lactic acid) enobunzima obuthile beemolekyuli yenziwa ngendlela yokwenziwa kweekhemikhali, kwaye emva koko i-glucose yafunyanwa nge-saccharification. Le mveliso inokubola kakuhle kwaye inokonakala ngokupheleleyo ziintsholongwane zendalo emva kokusetyenziswa ukuvelisa i-carbon dioxide namanzi, ezingayi kungcolisa okusingqongileyo emva kokusetyenziswa. Iluncedo kakhulu kukhuseleko lokusingqongileyo kwaye ithathwa njengezinto ezinobuhlobo nokusingqongileyo.
Okwangoku, izinto eziphambili zebhayoloji zeengxowa zeplastiki ezibolayo zenziwe yi-PLA + PBAT, enokubola ngokupheleleyo ibe ngamanzi kunye ne-carbon dioxide kwiinyanga ezi-3-6 phantsi kwemeko yokwenza umgquba (ii-degrees ezingama-60-70). Akukho ngcoliseko kwindalo esingqongileyo. Kutheni kufuneka kongezwe i-PBAT? I-PBAT yi-copolymer ye-adipic acid, i-1, i-4-butanediol kunye ne-terephthalic acid, eyi-polymer ye-aliphatic kunye ne-aromatic ebolile ngokupheleleyo eyenziwe ngeekhemikhali. I-PBAT inokuguquguquka okugqwesileyo kwaye ingasetyenziselwa ukukhupha ifilimu, ukubumba nge-blow, ukugquma nge-extrusion kunye nezinye iinkqubo zokubumba. Ukudibanisa i-PLA kunye ne-PBAT kwenzelwe ukuphucula ukuqina, ukubola kwe-biogradability kunye nokukwazi ukwakheka kwe-PLA.
2. Baphi abavelisi beengxowa ezinokubola ezinegama elihle?
Kwicandelo leengxowa zeplastiki ezibolayo, zenze umatshini okhethekileyo wokuvuthela iifilimu, umatshini wokushicilela, umatshini wokusika iingxowa, i-granulator yokuphinda usebenzise inkunkuma kunye neendlela ezahlukeneyo zemveliso ezivuthiweyo zeengxowa zeplastiki ezibolayo. Iimveliso zigubungela iingxowa zevesti, iingxowa zenkunkuma, iingxowa zezandla, iingxowa zempahla, iingxowa zehardware, iingxowa zezithambiso, iingxowa zokutya, iingxowa zeentloko zekhadi, iingxowa zephepha le-kraft /PLA composite, njl.njl., umgangatho ozinzileyo, ukusebenza kakuhle kwemveliso, ukuprinta okuhle, ukumelana nokufuma, ukumelana nokubhoboka, okungenatyhefu, ukutywina okuhle, ukolula okuhle, ukuthungwa okuhle, ukhuseleko lokusingqongileyo.
Ukupakisha okulungile kunamathela kwingcamango yokukhuselwa kwendalo kwaye kuzimisele uphuhliso oluzinzileyo lwendalo, kuphuhliswe ngempumelelo kufanelekile kwishishini lokupakisha kunye nokubonelela ngezixhobo kunye neemveliso ezibolayo ngokupheleleyo, kunamava amaninzi kushishino lokupakisha kwaye kuphendula kuhlu lwenkunkuma, kukhuthaze ukusetyenziswa kwakhona kwezixhobo, kwaye kuphuhliswe ngenkuthalo iimveliso ezibolayo ngokupheleleyo ezikumgangatho wokutya.
3. Zeziphi iimveliso ezinokusetyenziswa kuzo iingxowa ezibolayo?
Iingxowa zeplastiki ezibolayo zisetyenziswa kakhulu kwiihempe, ukuluka, iimpahla, impahla, amalaphu, ukutya, izixhobo zekhompyutha, izinto zombane, izinto zokuthambisa kunye neminye imimandla. Iingxowa zeplastiki ezibolayo zineendlela ezininzi zokuvala, ezifana nethambo elinamathelayo, iziphu, iteyiphu, njl.njl., kwaye iingxowa zeplastiki ezibolayo zihlanganiswe nephepha, elinokusonga isitho esisezantsi. Ngoku, iingxowa zeplastiki ezibolayo zingena kuzo zonke iinkalo zobomi, kwaye kukho iintlobo ngeentlobo; Kwixesha elizayo, iingxowa zeplastiki ezibolayo ziya kuba yimveliso epheleleyo yoshishino lokupakisha.
