Izindaba - Kwembulwa Isitashi Sommbila Ku-Bioplastics: Iyini Indima Yaso?

Ezimpilweni zethu zansuku zonke, imikhiqizo yepulasitiki ikhona yonke indawo.Kodwa-ke, izinkinga ezikhulayo zemvelo ezibangelwa amapulasitiki endabuko ziye zashukumisela abantu ukuba bafune ezinye izindlela ezisimeme.Yilapho i-bioplastics iqala khona ukudlala.Phakathi kwazo, isitashi sombila sidlala indima ebalulekile njengengxenye evamile kuma-bioplastics.Ngakho, yini ngempela indimacornstarch ku-bioplastics?

1.Yini i-Bioplastics?
Ama-Bioplastic amapulasitiki enziwe ngezinto ezivuselelekayo njengezitshalo noma ama-microorganisms.Ngokungafani namapulasitiki endabuko, ama-bioplastics enziwa ngezinsiza ezivuselelekayo, ngaleyo ndlela abangele umthelela omncane kwezemvelo.Isitashi sommbila, phakathi kwabo, sivame ukusetshenziswa njengenye yezingxenye eziyinhloko ku-bioplastics.

2.Iqhaza Lesitashi Sommbila Kwi-Bioplastics

Isitashi sommbila senza imisebenzi emithathu emikhulu:
I-Cornstarch idlala indima ekuthuthukiseni, ekuqiniseni nasekuthuthukiseni izakhiwo zokucubungula kuma-bioplastics.Kuyi-polymer engahlanganiswa namanye ama-polymers angaboli noma ama-plasticizers akhe izakhiwo ezizinzile.Ngokungeza izithasiselo ezifanele kusitashi sombila, ubulukhuni, ukuguquguquka kanye nezinga lokuwohloka kwama-bioplastics lingalungiswa, liwenze afaneleke izimo ezihlukene zohlelo lokusebenza.
Ukuthuthukisa Amandla Emishini: Ukufakwa kwesitashi sombila kungathuthukisa ukuqina namandla aqinile we-bioplastics, kuwenze aqine kakhudlwana.

Ukuthuthukisa Ukusebenza Kokucubungula: Ukuba khona kwesitashi sombila kwenza ama-bioplastics athambile kakhulu ngesikhathi sokucutshungulwa, kube lula ukukhiqizwa kwemikhiqizo emise okwehlukene.

Ukwengeza, isitashi sombila sinokubola okuhle kakhulu kwe-biodegradability.Ngaphansi kwezimo ezifanele zemvelo, ama-microorganisms angakwazi ukudiliza isitashi sombila sibe izinhlanganisela ezilula ze-organic, ekugcineni zizuze ukuwohloka okuphelele.Lokhu kuvumela ama-bioplastics ukuthi aphinde asetshenziswe ngokwemvelo ngemva kokusetshenziswa, ukunciphisa ukungcoliswa kwemvelo.

Nokho, isitashi sombila sibuye sibe nezinselele ezithile.Isibonelo, ezindaweni ezishisa kakhulu noma ezinomswakama ophezulu, ama-bioplastics ajwayele ukulahlekelwa ukuzinza, okuthinta ukuphila kwawo nokusebenza kwawo.Ukuze kubhekwane nalolu daba, ososayensi basebenzela ukuthola izithasiselo ezintsha noma ukuthuthukisa izinqubo zokukhiqiza ukuze kuthuthukiswe ukumelana nokushisa nokumelana nomswakama we-bioplastics.

3.Izicelo Zesitashi Sommbila ku-Specific Bioplastics

Ukusetshenziswa kwesitashi sombila kuma-bioplastics athile kuyehluka kuye ngezakhiwo ezifiselekayo kanye nokusetshenziswa okuhlosiwe komkhiqizo wokugcina.Nazi izibonelo ezimbalwa:

I-Polylactic Acid (PLA): I-PLA iyi-bioplastic evame ukutholakala kusitashi sombila.Isitashi sommbila sisebenza njenge-feedstock ekukhiqizeni i-lactic acid, ebuye ifakwe i-polymer ukuze yakhe i-PLA.I-PLA eqiniswe ngesitashi sombila ibonisa izakhiwo ezithuthukisiwe zemishini, njengamandla aqinile kanye nokumelana nomthelela.Ngaphezu kwalokho, ukwengeza isitashi sommbila kungathuthukisa ukubola kwe-PLA, kuyenze ifanelekele ukusetshenziswa lapho ukukhathazeka kwemvelo kubaluleke kakhulu, njengeukusika alahlwayo, ukupakishwa kokudla, namafilimu ezolimo ezimboza ngabo izithombo zezihlahla.

I-Polyhydroxyalkanoates (PHA): I-PHA ingenye uhlobo lwe-bioplastic engakhiqizwa kusetshenziswa isitashi sombila njengomthombo wekhabhoni.Isitashi sommbila sivutshelwa amagciwane ukuze kukhiqizwe i-polyhydroxybutyrate (PHB), okuwuhlobo lwe-PHA.Ama-PHA aqiniswe ngesitashi sombila avame ukuba nokuzinza okungcono kokushisayo kanye nezakhiwo zemishini.Lawa ma-bioplastics athola ukusetshenziswa emikhakheni eyahlukene, okuhlanganisa ukupakisha, izisetshenziswa zezokwelapha, kanye nezolimo.

I-Bioplastics Esekelwe Isitashi: Kwezinye izimo, isitashi sombila sicutshungulwa ngokuqondile sibe yi-bioplastics ngaphandle kwesidingo sezinyathelo ezengeziwe ze-polymerization.I-bioplastics esekelwe isitashi ngokuvamile iqukethe inhlanganisela yesitashi sombila, ama-plasticizers, nezithasiselo ukuze kuthuthukiswe ukucutshungulwa kanye nezakhiwo zokusetshenziswa ekugcineni.Lawa ma-bioplastics asetshenziswa ezinhlelweni ezifana nezikhwama ezilahlwayo, iziqukathi zokudla, kanye ne-tableware elahlayo.

Ukuxutshwa Nezinye I-Biodegradable Polymers: Isitashi sombila singabuye sihlanganiswe namanye ama-polymers abolayo, njenge-polyhydroxyalkanoates (PHA), i-polycaprolactone (PCL), noma i-polybutylene adipate-co-terephthalate (PBAT), ukuze kwakhiwe ama-bioplastic anezakhiwo ezihambisanayo.Lezi zingxube zinikeza ibhalansi yamandla emishini, ukuguquguquka, kanye ne-biodegradability, okuyenza ifanelekele izinhlelo zokusebenza ezihlukahlukene kusukela ekupakishweni kuya kwezolimo.

4.Isiphetho

Iqhaza lesitashi sombila ku-bioplastics lidlulela ngalé kokuthuthukisa ukusebenza;kusiza futhi ekunciphiseni ukuncika kumapulasitiki endabuko asekelwe ku-petroleum, okuqhuba ukuthuthukiswa kwezinto ezibonakalayo eco-friendly.Ngokuthuthuka kwezobuchwepheshe, silindele ukubona imikhiqizo emisha ye-bioplastic esekelwe kuzinsiza ezivuselelekayo ezifana nesitashi sombila.

Kafushane, isitashi sombila sidlala indima ehlukahlukene kuma-bioplastics, hhayi nje ukuthuthukisa ukuzinza kwesakhiwo samapulasitiki kodwa futhi sithuthukisa ukubola kwawo, ngaleyo ndlela kunciphisa umthelela wemvelo.Ngokuqhubeka okuqhubekayo kwezobuchwepheshe kanye nokuqanjwa okusha, i-bioplastics isilungele ukudlala indima enkulu ekuletheni izinzuzo ezengeziwe endaweni yethu yoMhlaba.
