Esona sisombululo sisemgangathweni sokuthotywa kwendalo kweemveliso zeplastiki ezilahlwayo-- Reverte
Sonke siyazi ukuba iimveliso zeplastiki, ngakumbi iimveliso ezilahlwayo zeplastiki, zizise uxinzelelo olukhulu kwindalo yethu. Ihlabathi liphela likhangela indlela efanelekileyo nesebenzayo yokusombulula iingxaki ezibangelwa ziimveliso zeplastiki ezilahlwayo kwihlabathi.
Kule meko, sazisa iReverte, i-masterbatch ecekeceke enobungangamsha bendalo eveliswe e-UK, ekunokuthiwa sesona sisombululo sisiso kwiimveliso zeplastiki ezilahlwayo.
Iimveliso zeplastiki ezilahlwayo esizisebenzisayo ngoku zinokuthotywa. Kuthatha inkqubo ende kakhulu-ehlala iminyaka eyi-100 ukuya kuma-200. Kungenxa yokuba iplastiki yenziwa nge-polyethylene. Kuxhomekeke kwimeko ye-polymerization, i-polyethylene ehambelana nobunzima beemolekyuli ukusuka kwi-10,000 ukuya kwizigidi ezininzi. Ubunzima obuphezulu beemolekyuli kunzima ukuthoba indalo ngexesha elifutshane.
Kwaye Reverte izongezo ngeNorish reaction yamakhemikhali ethi ngokuphendula koqhakamshelwano ion ethile yesinyithi njenge-pre-oxidants, ubunzima bemolekyuli yeemveliso zeplastiki bunokuncitshiswa ngokukhawuleza bube yi-10000 okanye nangaphantsi kwama-5000 ngexesha elifutshane, ukuze iimveliso zeplastiki zibe ilahlwe emva kokuba isetyenzisiwe. Yatyiwa ngokukhawuleza yaza yatshabalala yintsholongwane. Ngamanye amagama, inokuchithwa ngokukhawuleza ngendalo, njengamagqabi, ixolo liyalahlwa
kwindalo kwaye ibolile ngokukhawuleza ngamagciwane.
Indima yeReverte yahlulwe yangamacandelo amabini. Eyokuqala kukuba emva kokuba imveliso yeplastiki elahlwayo isetyenzisiwe, iyaqhubeka nokukhanya kunye ne-oxidation, kwaye ukusabela kweekhemikhali okungathandekiyo kuqala ngaphakathi kweeyure ezingama-48, kwaye ubunzima bemolekyuli buncitshisiwe; okwesibini kuxa ubunzima beemolekyuli buncitshisiwe baba li-10 000 okanye nangaphantsi kwama-5 000. , Njengombandela wendalo, inokudliwa zii-microorganism ds kwaye ikhukuliswe ngokukhawuleza. Kwaye inoyilo olusebenziseka lula kakhulu. Xa ezi mveliso zeplastiki zinokuthi zitywinwe ebhokisini kwaye zingasetyenziswanga, aziyi kuthoba isidima, kwaye ukusebenza kwazo kunokugcinwa iminyaka emi-2.
Faka nje kwi-1% yokubuyisela i-masterbatch kwitanki lokuxuba xa uvelisa ifilimu yeplastiki, ifilimu yakho yeplastiki iya kuba yintsholongwane.
Okwangoku, amashishini amaninzi akhetha imveliso esekwe kwisitashi ukuze afezekise ukuthotywa. Makhe ngokufutshaneUhlalutye izibonelelo kunye nezinto ezingalunganga zeReverte yethu kunye nePLA.
Okokuqala: Ukongeza iReverte kwiiplastiki ezilahlayo kungenza ukuba ihlazeke ngokuthe ngqo kwindalo, nokuba injalo ilahlwe ngokuthe ngqo, ayizukubangela iingxaki kwezendalo.
Okwangoku, uninzi lweemveliso zeplastiki zePLA zenziwe ngamasuntswana ePLA axutywe namasuntswana eplastiki e-PE. I-PLA kufuneka ibenjaloithobeke kancinci phantsi kweemeko zokugalela umgquba, kwaye amasuntswana e-PE akazukuthotywa. Ukwenza isichumisi kakhuluinzima. Ayikuko ukungcwaba nje emhlabeni. Ngapha koko, zimbini izinto. Okokuqala, ukufaka umgqubaizixhobo, ezibhekisa kwizitishi zokwenza umgquba okanye imigqomo yemigqomo; Okwesibini, iimeko ezifanelekileyo, oku kubhekisa kwiukwenziwa kwezinto zomgquba, ezifuna inkunkuma ephilayo kunye nezinto ezincinci, kwaye kunokufezekiswa kuphela ngaphantsi ubushushu obuthile, ukufuma kunye neemeko zentsholongwane. Ezi zinto zimbini zichonga ubunzima beukwenza umgquba. Asinazo izixhobo zokuchumisa. Kufuneka sizithenge. Kuya kufuneka sikhethe okungaphiliyoumba kwinkunkuma ukunqanda ukuxubana nezinto ezinokuchumeka, kuba izinto ezingaphiliyo azinakwenziwa mgquba.
Okwesibini: Iimveliso zokugqibela zokuthotywa kusetyenziswa iReverte yicarbon dioxide kunye namanzi. Sisiphumo sokugayangamagciwane.
Ukusetyenziswa komgquba we-PLA kuya kuvelisa ubushushu obuphezulu kunye ne-biogas (methane). Njengoko sonke sisazi, eyona methane iphambiliigesi yendlu eluhlaza.
Okwesithathu: I-Reverte ayihlali kwizixhobo zokutya ezixabisekileyo.
Ukusetyenziswa kweemveliso zeplastiki yePLA okunene kuguqula ukutya (uninzi lwezinto zePLA eziluhlaza zivela kumbona) iimveliso ezilahlwayo. Ngenxa yokunqongophala kokutya ehlabathini, inani labantu abalambileyo liyaqhubekaukwanda, kwaye nakuphi na ukuziphatha okuchitha ukutya kuya kudibana neengxaki kunye nemingcipheko.
Okwesine: ukusebenzisa iReverte kuqoqosho ngakumbi kune-PLA.
Okwesihlanu: Iimveliso zokugqibela zokuthotywa kusetyenziswa iReverte zinokuphinda zisebenze ngaphambi kokuba ubunzima beemolekyuli bungehli 10,000, banokuba ngamasuntswana eeplastiki aqhelekileyo axutywe namanye amasuntswana eplastiki aphinde asetyenziswe.
Okwangoku akukho sigqibo sokugqibela malunga nokuba i-PLA inokuphinda isetyenziswe kwakhona iphinde isetyenziselwe i-granulation.
