Izinkomishi zephepha ezihlanganiswe nge-PE kanye ne-PLA ziyizinto ezimbili ezivamile zenkomishi yephepha emakethe okwamanje. Zinomehluko omkhulu mayelana nokuvikelwa kwemvelo, ukuphinda kusetshenziswe kanye nokusimama. Lesi sihloko sizohlukaniswa ngezigaba eziyisithupha ukuze kuxoxwe ngezici kanye nokwehluka kwalezi zinhlobo ezimbili zezinkomishi zephepha ukukhombisa umthelela wazo ekusimameni kwemvelo.
I-PE (i-polyethylene) ne-PLA (i-polylactic acid) izinkomishi zephepha ezinamekwe yizinto ezimbili ezivamile zenkomishi yephepha. Izinkomishi zephepha ezinamekwe nge-PE zenziwe ngepulasitiki yendabuko ye-PE, kuyilapho izinkomishi zephepha ezihlanganiswe ne-PLA zenziwe ngezinto zezitshalo ezivuselelekayo ze-PLA. Lesi sihloko sihlose ukuqhathanisa umehluko ekuvikelweni kwemvelo, ukuphinda kusetshenziswe kabusha kanye nokusimama phakathi kwalezi zinhlobo ezimbili zeizinkomishi zephephaukusiza abantu ukuthi benze izinqumo ezingcono mayelana nokusebenzisa izinkomishi zephepha.
1. Ukuqhathaniswa kokuvikelwa kwemvelo. Mayelana nokuvikelwa kwemvelo, izinkomishi zephepha ezihlanganiswe ne-PLA zingcono nakakhulu. I-PLA, njenge-bioplastic, yenziwe ngezinto ezingavuthiwe zezitshalo. Uma kuqhathaniswa, izinkomishi zephepha ezihlanganiswe nge-PE zidinga izinsiza ze-petroleum njengezinto zokusetshenziswa, ezinomthelela omkhulu emvelweni. Ukusebenzisa izinkomishi zephepha ezihlanganiswe ne-PLA kusiza ukunciphisa ukuncika emandleni ezinto ezimbiwa phansi futhi kuvikelwe imvelo.
Ukuqhathanisa ngokuya kokuphinda kusetshenziswe kabusha. Mayelana nokusetshenziswa kabusha,Izinkomishi zephepha eziboshwe nge-PLAzingcono futhi kunezinkomishi zephepha eziboshwe nge-PE. Njengoba i-PLA iyinto ebolayo, izinkomishi zephepha ze-PLA zingagaywa kabusha futhi zicutshungulwe kabusha zibe izinkomishi zephepha ze-PLA ezintsha noma eminye imikhiqizo ye-bioplastic. Izinkomishi zephepha ezinamekwe nge-PE zidinga ukudlula ezinqubweni zokuhlunga nokuhlanza okuchwepheshile ngaphambi kokuthi ziphinde zisetshenziswe. Ngakho-ke, izinkomishi zephepha ezihlanganiswe ne-PLA kulula ukuzisebenzisa futhi ziphinde zisetshenziswe, ngokuhambisana nomqondo womnotho oyindilinga.
3. Ukuqhathanisa mayelana nokusimama. Uma kukhulunywa ngokusimama, izinkomishi zephepha eziboshwe nge-PLA ziphinde zibe nesandla esiphezulu. Inqubo yokukhiqiza ye-PLA isebenzisa izinsiza ezivuselelekayo, njenge-cornstarch nezinye izinto zezitshalo, ngakho inomthelela omncane emvelweni. Ukukhiqizwa kwe-PE kuncike emithonjeni ye-petroleum elinganiselwe, okufaka ingcindezi enkulu endaweni ezungezile. Ngaphezu kwalokho, izinkomishi zephepha ezihlanganiswe ne-PLA zingakwazi ukuwohloka zibe amanzi kanye ne-carbon dioxide, okubangela ukungcoliswa okuncane enhlabathini nasemizimbeni yamanzi, futhi zisimeme.
Ukucatshangelwa okuhlobene nokusetshenziswa kwangempela. Ngokombono wokusetshenziswa kwangempela, kukhona futhi umehluko phakathi kwezinkomishi zephepha ezimbozwe i-PE nezinkomishi zephepha ezihlanganiswe ne-PLA.Izinkomishi zephepha eziboshwe nge-PEzikwazi ukumelana nokushisa okuhle nokumelana nokubanda futhi zifanele ukupakisha iziphuzo ezishisayo nezibandayo. Kodwa-ke, impahla ye-PLA izwela kakhulu izinga lokushisa futhi ayifanele ukugcina uketshezi olushisa kakhulu, okungabangela kalula inkomishi ukuthi ithambe futhi igxumeke. Ngakho-ke, izidingo ezithile zokusetshenziswa zidinga ukucatshangelwa lapho ukhetha izinkomishi zephepha.
Ukufingqa, kunomehluko osobala phakathi kwezinkomishi zephepha ezimbozwe i-PE kanye nezinkomishi zephepha ezimbozwe i-PLA ngokuphathelene nokuvikelwa kwemvelo, ukusebenziseka kabusha nokusimama. Izinkomishi zephepha ezihlanganiswe ne-PLA zinokuvikeleka okungcono kwemvelo,ukusebenziseka kabusha nokusimama, futhi okwamanje ziyinketho enconywa kakhulu ehambisana nemvelo. Nakuba ukumelana nezinga lokushisa kwezinkomishi zephepha ezinamekwe nge-PLA akukuhle njengalokho kwezinkomishi zephepha ezinamekwe nge-PE, izinzuzo zakhona zingaphezu kokubi. Kufanele sikhuthaze abantu ukuthi basebenzise izinkomishi zephepha ezimbozwe i-PLA ukuze kuthuthukiswe intuthuko esimeme. Lapho ukhetha izinkomishi zephepha, ukucatshangelwa okuphelele kufanele kwenziwe ngokusekelwe ezidingweni ezithile, kanye nokusetshenziswa kweizinkomishi zephepha ezi-eco-friendly futhi eziqhubekayokufanele isekelwe ngokuqhubekayo. Ngokusebenzisana, singenza ukusetshenziswa kwenkomishi yephepha kube nobungane ngokwemvelo, kusetshenziswe kabusha futhi kusimeme.
