Izindaba - Ukwembulwa kwesitashi sommbila ku-bioplasters: Iyini indima yayo?

Ezimpilweni zethu zansuku zonke, imikhiqizo yepulasitiki iyabucayi. Kodwa-ke, izingqinamba ezandayo zemvelo ezibangelwa amapulasitiki wendabuko ziye zashukumisela abantu ukuthi bafune ezinye izindlela ezizinzile. Yilapho ama-bioplastics aqala ukudlala khona. Phakathi kwazo, isitashi sommbila sidlala indima ebalulekile njengengxenye evamile kuma-bioplasters. Ngakho-ke, iyini ngempela indima yeI-Cornstarch ku-bioplastics?

1.Yini i-bioplastics?
Ama-Bioplastics amapulaphuli enziwe ngezinsizakusebenza ezivuselelekayo ezinjengezitshalo noma ama-microorganisms. Ngokungafani namapulasitiki wendabuko, ama-bioplastics enziwa emithonjeni evuselelekayo, ngaleyo ndlela ebangela umthelela omncane emvelo. Isitashi sommbila, phakathi kwawo, ngokuvamile sisetshenziswa njengenye yezinto eziphambili kuma-bioplasters.

2.I indima yesitashi sommbila kuma-bioplastics

Isitashi sommbila ngokuyinhloko kusebenza imisebenzi emithathu emikhulu:
I-Cornstarch idlala indima ekuthuthukiseni, izinzile kanye nokwenza ngcono izakhiwo zokucubungula kuma-bioplasters. Kuyi-polymer engahlanganiswa namanye ama-polymers noma amapulasitiki ukwakha izakhiwo ezinzile. Ngokungeza izengezo ezifanele ku-Corn Starch, ubulukhuni, ukuguquguquka kanye nezinga lokuwohloka kwama-bioplastics kungalungiswa, kubenze balungele izimo ezihlukile zohlelo lokusebenza.
Ukuthuthukisa amandla emishini: Ukufakwa kwesitashi sommbila kungathuthukisa ubulukhuni namandla ashubile ama-bioplastics, abenze basebenze kanzima.

Ukwenza ngcono ukusebenza kwe-Processing: Ukuba khona kwesitashi sommbila kwenza ama-bioplastics angenayo ngokwengeziwe ngesikhathi sokucubungula, okwenza ukukhiqizwa kwemikhiqizo ehlukahlukene ebekiwe.

Ngokwengeziwe, isitashi sommbila sinaso i-biodegrade enhle kakhulu. Ngaphansi kwezimo ezifanele zezemvelo, ama-microorganisms angaphula isitashi sommbila abe amakhompiyutha alula we-organic, ekugcineni athole ukonakaliswa okuphelele. Lokhu kuvumela ama-bioplastics ukuba asebenze ngokwemvelo ngemuva kokusetshenziswa, anciphise ukungcoliswa kwemvelo.

Kodwa-ke, isitashi sommbila futhi sethula ezinye izinselelo. Isibonelo, ezindaweni zokushisa eziphakeme noma eziphakeme zomswakama, ama-bioplastics athambekele ekulahlekelweni ukuqina, okuthinta ukusebenza kwawo kanye nokusebenza kwawo. Ukubhekana nalolu daba, ososayensi basebenzela ukuthola izithasiselo ezintsha noma ukwenza ngcono izinqubo zokukhiqiza ukuthuthukisa ukumelana nokushisa kanye nokuphikiswa komswakama kwama-bioplasters.

3.Izicelo zesitashi sommbila ku-bioplastics ethile

Ukusetshenziswa kwesitashi sommbila ku-bioplastics ethile kuyahlukahluka ngokuya ngezakhiwo ezifiselekayo kanye nokusetshenziswa okuhlosiwe komkhiqizo wokugcina. Nazi izibonelo ezimbalwa:

I-Polylactic acid (PLA): PLA yi-bioplastic evame ukuthathwa ngesitashi sommbila. Isitabane se-Corn sisebenza njengesiqu sokuphakelayo sokukhiqizwa kwe-lactic acid, esenziwa nge-polymerized ukuze kwakhiwe i-PLA. I-PLA yaqiniswa nge-Corn Starch Excries ethuthukisiwe yemishini, njengamandla ashubile kanye nokumelana nomthelela. Ngaphezu kwalokho, ukungezwa kwesitashi sommbila kungakhulisa i-biodegradeability ye-pla, okwenza kube lula ukuthola izicelo lapho ukukhathazeka kwemvelo kubaluleke kakhulu, njengeUkulahlwa kwe-cutlery, Ukupakishwa kokudla, namafilimu we-mulch ezolimo.

I-Polyhydroxyalkalkoates (Pha): I-PHA ngolunye uhlobo lwe-bioplastic olungakhiqizwa kusetshenziswa isitashi sommbila njengomthombo wekhabhoni. Isitashi se-Corn savulwa ama-microorganisms ukukhiqiza i-polyhydroxyButrate (PHB), okuwuhlobo lwe-PHA. I-Phat yaqiniswa ngesitashi sommbila zivame ukuba nokuqina okungcono okushisayo kanye nezakhiwo zemishini. Lawa bioplastics athola izinhlelo zokusebenza emikhakheni ehlukahlukene, kufaka phakathi ukupakisha, amadivaysi ezokwelapha kanye nezolimo.

I-Bioplastics esekelwe eStarch-esekwe esitokisini: Kwezinye izimo, isitashi sommbila sicutshungulwa ngokuqondile kuma-bioplastics ngaphandle kwesidingo sezinyathelo ezingezekile ze-polymerization. I-Bioplastics esekelwe eStarch-based iqukethe ukuhlanganiswa kwesitashi sommbila, amapulasitiki, kanye nezithasiselo ukwenza ngcono ukucubungula kanye nokusetshenziswa kwezindawo. Lezi zingcingo zisetshenziswa kuzinhlelo zokusebenza ezinjengezikhwama ezilahlayo, iziqukathi zokudla, kanye nethebureware elahlwayo.

Ukuhlanganiswa namanye ama-polymers angenakuzalwa Lezi zinhlanganisela zinikela ngemali esele yamandla emishini, ukuguquguquka, kanye ne-biodegladability, kubenza balungele izinhlelo zokusebenza ezivela ekufakweni kwezolimo.

4.Conclusion

Iqhaza lesitashi sommbila kuma-bioplastics lingaphezu kokuthuthukisa ukusebenza; Kuyasiza nokunciphisa ukuncika kumapulasitiki asuselwa endabuko kaphethiloli, aqhuba ukuthuthukiswa kwezinto ezinobungane. Ngentuthuko kwezobuchwepheshe, silindele ukubona imikhiqizo eminingi ye-bioplastic esuselwa kwizisetshenziswa ezingavuselelekayo ezifana nesitashi sommbila.

Ngamafuphi, isitashi sommbila sidlala indima ehlukahlukene kuma-bioplastics, hhayi kuphela ukuthuthukisa ukuqina kwesakhiwo kodwa futhi kuthuthukisa i-biodegrade, ngaleyo ndlela kunciphise umthelela wezemvelo. Ngenqubekela phambili yezobuchwepheshe eqhubekayo kanye nokwenziwa okusha, ama-bioplasters alungele ukudlala indima enkulu ekuletheni izinzuzo eziningi zemvelo yomhlaba wethu.
