Isixazululo esifanelekile sokonakaliswa kwemvelo kwemikhiqizo epulasitiki elahlwayo --- Reverte
Sonke siyazi ukuthi imikhiqizo yepulasitiki, ikakhulukazi imikhiqizo elahlwayo epulasitiki, ilethe ingcindezi enkulu emvelweni yethu. Umhlaba wonke ufuna indlela efanelekile nephumelelayo yokuxazulula izinkinga ezidalwa yimikhiqizo epulasitiki elahlwayo emhlabeni.
Kulesi simo, sethula iReverte, i-masterbatch enobuchwepheshe obucekeceke kakhulu kwezemvelo ekhiqizwe e-UK, okungathiwa iyisixazululo esihle kakhulu semikhiqizo yepulasitiki elahlwayo.
Imikhiqizo epulasitiki elahlwayo esiyisebenzisayo njengamanje ingahle yehliswe. Kuthatha inqubo ende kakhulu ethatha iminyaka eyi-100 kuya kwengu-200. Lokhu kungenxa yokuthi ipulasitiki yenziwa nge-polyethylene. Ngokuya ngezimo ze-polymerization, i-polyethylene ehlobene nesisindo samangqamuzana isukela ku-10 000 kuya ezigidini ezimbalwa. Isisindo esinjalo samangqamuzana kunzima ukwehlisa imvelo esikhathini esifushane.
Futhi Reverte izithasiselo ngokusebenzisa i-Norrish chemical reaction lapho kusetshenziswa ukuthintana kokuthintana kwama-ayoni athile wensimbi njengama-pre-oxidants, isisindo samangqamuzana semikhiqizo yepulasitiki singancishiswa ngokushesha sibe ngu-10000 noma nangaphansi kuka-5000 ngesikhathi esifushane, ukuze imikhiqizo yepulasitiki ibe ilahlwe ngemuva kokusetshenziswa. Yadliwa ngokushesha yagugiswa amagciwane. Ngamanye amagama, ingabola masinyane ngokwemvelo, njengamaqabunga, ikhasi liyalahlwa
endalweni futhi isheshe yabola ngama-microorganisms.
Indima kaReverte ihlukaniswe izingxenye ezimbili. Okokuqala ukuthi ngemuva kokuthi umkhiqizo olahlwayo wepulasitiki usetshenzisiwe, uthola ukukhanya ne-oxidation, bese ukusabela kwamakhemikhali amaNorrish kuqala kungakapheli amahora angama-48, futhi isisindo samangqamuzana sinciphile; okwesibili kulapho isisindo samangqamuzana sehliselwa ku-10,000 noma nangaphansi kuka-5,000. , Njengendaba ephilayo emvelweni, ingadliwa ngama-microorganism ds futhi isuswe ngokushesha. Futhi futhi inomklamo wokusebenziseka kalula. Lapho le mikhiqizo epulasitiki elahlwayo ivalwa ebhokisini futhi ingasetshenziswa, ngeke yehlise, futhi ukusebenza kwayo kungagcinwa iminyaka emi-2.
Ungayisebenzisa kanjani i-Reverte? Faka nje ku-1% yokubuyisela emuva i-masterbatch ethangini lokuxuba lapho ukhiqiza ifilimu epulasitiki, ifilimu yakho yepulasitiki izokwazi ukubola.
Njengamanje, amabhizinisi amaningi akhetha umkhiqizo osuselwa kusitashi i-PLA ukufeza umphumela wokonakala. Ake sisho kafushanehlaziya ubuhle nobubi beReverte ne-PLA yethu.
Okokuqala: Ukungeza i-Reverte kupulasitiki ongalahlwa kungenza ukuthi yehliswe ngokuqondile emvelweni, noma ngabe kunjalo ilahlwe ngqo, ngeke idale izinkinga zemvelo.
Njengamanje, iningi lemikhiqizo yeplastiki ye-PLA yenziwe ngezinhlayiya ze-PLA ezihlanganiswe nezinhlayiya zepulasitiki ze-PE. I-PLA kumele ibekwehliswe kancane ngaphansi kwezimo zomquba, futhi izinhlayiya ze-PE ngeke zehliswe. Ukwenza umquba kakhulueziyinkimbinkimbi. Akukona nje ngokumane ungcwabe emhlabathini. Eqinisweni, kunezinto ezimbili. Okokuqala, ukufaka umqubaizinsiza, ezibhekisa eziteshini zokwenza umquba noma imigqomo yomquba; okwesibili, izimo ezifanelekile, lokhu kubhekisa kuukwakheka kwento yokwenza umquba, odinga imfucuza engokwemvelo nezilwanyana ezincane, futhi kungatholwa kuphela ngaphansi ukushisa okuthile, umswakama kanye nezimo ezincane. Lezi zinto ezimbili zinquma ubunzima beukufaka umquba. Asinazo izindawo zokufaka umquba. Sidinga ukuzithenga. Kufanele sikhethe okungaphiliinto kudoti ukugwema ukuxubana nezinto ezingavundiswa, ngoba izinto ezingaphili azikwazi ukwenziwa umquba.
Okwesibili: Imikhiqizo yokugcina yokonakala usebenzisa i-Reverte yi-carbon dioxide namanzi. Kungumphumela wokugaya ukudlangama-microorganisms.
Ukusetshenziswa komquba we-PLA kuzokhiqiza ukushisa okuphezulu kanye ne-biogas (methane). Njengoba sonke sazi, i-methane yiyona ehamba phambiliigesi yokushisa.
Okwesithathu: I-Reverte ayinayo imithombo yokudla eyigugu.
Ukusetshenziswa kwemikhiqizo yepulasitiki ye-PLA empeleni kuguqula ukudla (iningi lezinto zokusetshenziswa ze-PLA zivela kokukhishwa kommbila) imikhiqizo elahlwayo. Ngokuqhubeka kokuntuleka kokudla emhlabeni, inani labantu abalambile liyaqhubekaukwanda, futhi noma yikuphi ukuziphatha okuchitha ukudla kuzobhekana nezingqinamba nezingozi eziningi.
Okwesine: ukusebenzisa iReverte kungokonga kakhulu kune-PLA.
Okwesihlanu: Imikhiqizo yokugcina yokonakala kusetshenziswa iReverte iyakwazi ukuphinda isebenze ngaphambi kokuba isisindo samangqamuzana singakawi 10,000, zisengaba izinhlayiya zepulasitiki ezejwayelekile ezixubene nezinye izinhlayiya zepulasitiki futhi ziphinde zisetshenziswe futhi.
Okwamanje asikho isiphetho sokugcina sokuthi i-PLA ingabuye isetshenziswe kabusha futhi isetshenziselwe ukusetshenziswa kwe-granulation.
