Ngoku ukuba isantya somyalelo weengxowa zeplastiki sehlile, iivenkile ezincinci eziqhelekileyo okanye iivenkile ezisecaleni kwendlela zidla ngokuba ziingxowa zeplastiki eziqhelekileyo, pp, pe, njl. .Ukongezwa kwee-degradants kwamanye amasuntswana eplastiki kusasetyenziswa kancinci, kwaye iimolekyuli zeplastiki ezibolileyo ziya kuba nefuthe kwindalo.
Nangona kunjalo, ezinye iivenkile ezinkulu ezinkulu kunye nodederhu lweevenkile zisebenzisa iingxowa ezonakaliseka ngokupheleleyo, ezenziwe ngemathiriyeli ekrwada elungisiweyo eyenziwe yi-pbat, ipla kunye ne-cornstarch.Olu hlobo lwengxowa luchithwa ngokupheleleyo kwaye ukuqina kwayo akukho ngaphantsi kweengxowa zeplastiki eziqhelekileyo..Iya kuthotywa ngokupheleleyo ibe yikharbon diokside namanzi malunga neenyanga ezi-3 emhlabeni, kwaye inokugcinwa kangangeenyanga ezisi-9 ukuya kwezili-12 kwindawo yokugcina impahla eyomileyo.
Umahluko phakathi kweengxowa zeplastiki ezinokubola ngokupheleleyo kunye neeplastiki eziqhelekileyo
1. Izinto ezahlukeneyo
Iingxowa zeplastiki eziguquguqukayo ngokupheleleyo (oko kukuthi, iingxowa zeplastiki ezihambelana nokusingqongileyo) zenziwe ngePLA, PHAs, PBA, PBS kunye nezinye izinto zepolymer.Iingxowa zeplastiki eziqhelekileyo ezingonakali zezinye izinto zeplastiki ezifana ne-PE.
2. Imigangatho eyahlukeneyo yokuvelisa
Iingxowa zeplastiki ezonakaliswa ngokupheleleyo zifuna ukuhlangabezana nomgangatho wesizwe we-GB/T21661-2008, ofikelele kumgangatho wokhuseleko lokusingqongileyo.Iingxowa zeplastiki eziqhelekileyo ezingenakonakala eziqhelekileyo azidingi ukuthobela lo mgangatho.
3. Ixesha lokubola lahlukile.Ngokubanzi, iingxowa zeplastiki ezinokubola ngokupheleleyo zinokubola kungaphelanga unyaka omnye, kwaye iiplastiki ezikhuselweyo zeOlimpiki zokusingqongileyo zinokuqala ukubola kwiintsuku ezingama-72 emva kokuba zilahliwe.Kuthatha iminyaka engama-200 ukuba iingxowa zeplastiki eziqhelekileyo eziqhelekileyo ezingenakonakala zithotywe.
Izinto eziluncedo zokusebenzisa iingxowa zeplastiki ezinokonakala ngokupheleleyo
1. Ukhuseleko lokusingqongileyo: Ukusetyenziswa kweengxowa zeplastiki ezinokubola ngokupheleleyo kunokunciphisa kakhulu ingxaki yongcoliseko olumhlophe olubangelwa kukungakwazi ukubola kweengxowa zeplastiki eziqhelekileyo.
2. Ukusebenza okugqwesileyo: Ingxowa yeplastiki enokubola ngokupheleleyo isebenzisa istatshi njengesona sixhobo siphambili, amandla okuncipha angcono kunezinye izinto, ubomi benkonzo bude kunobo besikhwama sephepha, kwaye iindleko ziphantsi kunezo zengxowa yephepha. .
3. Igqwesile kwaye iyaguquguquka: Isingxobo seplastiki esinokonakala ngokupheleleyo kunye neplastiki eqhelekileyo zinomsebenzi ofanayo ngaphandle kwamacandelo ahlukeneyo kunye nemathiriyeli.Zinokuprintwa kakuhle, zibephakathi ngobukhulu, kwaye zinokupakisha iimveliso ezininzi.
4. Ukurisayikilishwa kwakhona: Ingxowa yeplastiki enokubola ngokupheleleyo ineempawu zokuthamba, ukungagugi, ukusongeka kunye nokuthungwa okuhle, kwaye ixesha lokuphinda lisetyenziswe lide.
