Iindaba - Ukuvula iStarch yoMbona kwiBioplastics: Yintoni Indima Yayo?

Kubomi bethu bemihla ngemihla, iimveliso zeplastiki zixhaphakile. Nangona kunjalo, iingxaki zokusingqongileyo ezikhulayo ezibangelwa ziiplastiki zemveli ziye zabangela ukuba abantu bafune ezinye iindlela ezizinzileyo. Kulapho ke ii-bioplastics ziqala khona ukusebenza. Phakathi kwazo, isitatshi sombona sidlala indima ebalulekileyo njengenxalenye eqhelekileyo kwii-bioplastics. Ngoko ke, yintoni kanye kanye indimai-cornstarch kwi-bioplastics?

1. Zithini iiBioplastics?
Ii-bioplastics ziiplastiki ezenziwe ngezinto ezivuselelekayo ezifana nezityalo okanye iintsholongwane. Ngokungafaniyo neeplastiki zemveli, ii-bioplastics zenziwe ngezinto ezivuselelekayo, nto leyo ebangela impembelelo encinci kokusingqongileyo. Isitatshi sombona, phakathi kwazo, sisetyenziswa njengenye yezona zinto ziphambili kwi-bioplastics.

2. Indima yesitatshi sombona kwi-Bioplastics

Isitatshi sombona ikakhulu isebenza imisebenzi emithathu ephambili:
I-cornstarch idlala indima ekuphuculeni, ekuzinziseni nasekuphuculeni iipropati zokucubungula kwi-bioplastics. Yi-polymer enokudityaniswa nezinye ii-polymers ezinokubola okanye ii-plasticizers ukuze zenze izakhiwo ezizinzileyo. Ngokongeza izongezo ezifanelekileyo kwi-corn starch, ubunzima, ukuguquguquka kunye nesantya sokuwohloka kwe-bioplastics sinokulungiswa, okwenza ukuba zilungele iimeko ezahlukeneyo zokusetyenziswa.
Ukuphucula Amandla Oomatshini: Ukufakwa kwesitatshi sombona kunokuphucula ukuqina kunye namandla okuxinana kwee-bioplastics, okuzenza zihlale ixesha elide.

Ukuphucula Ukusebenza Kokucubungula: Ubukho besitatshi sombona kwenza ii-bioplastics zikwazi ukunyibilika ngakumbi ngexesha lokucubungula, nto leyo eyenza kube lula ukuveliswa kweemveliso ezahlukeneyo ezimile okweemilo.

Ukongeza, istatshi sombona sinokubola kakuhle. Phantsi kweemeko ezifanelekileyo zokusingqongileyo, iintsholongwane zinokuqhekeza istatshi sombona sibe ziikhompawundi ezilula ze-organic, ekugqibeleni zifikelele ekuwohlokeni ngokupheleleyo. Oku kuvumela ii-bioplastics ukuba ziphinde zisetyenziswe ngokwendalo emva kokusetyenziswa, nto leyo enciphisa ungcoliseko lokusingqongileyo.

Nangona kunjalo, istatshi sombona sikwanika nemingeni ethile. Umzekelo, kwiindawo ezinobushushu obuphezulu okanye ezinomswakama ophezulu, ii-bioplastics zinokulahlekelwa kukuzinza, nto leyo echaphazela ubomi bazo kunye nokusebenza kwazo. Ukujongana nale ngxaki, izazinzulu zisebenza ekufumaneni izongezo ezintsha okanye ukuphucula iinkqubo zemveliso ukuze ziphucule ukuxhathisa ubushushu kunye nokuxhathisa ukufuma kwee-bioplastics.

3.Ukusetyenziswa kwesitatshi sengqolowa kwi-Bioplastics ethile

Ukusetyenziswa kwesitatshi sombona kwi-bioplastics ethile kuyahluka ngokuxhomekeke kwiimpawu ezifunwayo kunye nendlela ekucetywayo ukusetyenziswa ngayo imveliso yokugqibela. Nazi imizekelo embalwa:

I-Polylactic Acid (PLA): I-PLA yi-bioplastic edla ngokufunyanwa kwisitatshi sombona. Isitatshi sombona sisebenza njengesondlo sokuvelisa i-lactic acid, emva koko i-polymerized ukuze yenze i-PLA. I-PLA eqiniswe yisitatshi sombona ibonisa iipropati eziphuculweyo zoomatshini, ezifana namandla okuxinana kunye nokumelana nempembelelo. Ngaphezu koko, ukongezwa kwesitatshi sombona kunokuphucula ukubola kwe-PLA, okwenza ukuba ifaneleke ukusetyenziswa apho iingxaki zokusingqongileyo zibaluleke kakhulu, ezifanaizixhobo zokusela ezilahlwayo, ukupakishwa kokutya, kunye neefilimu ze-mulch yezolimo.

IiPolyhydroxyalkanoates (PHA): I-PHA lolunye uhlobo lwe-bioplastic olunokuveliswa kusetyenziswa istatshi sombona njengomthombo wekhabhoni. Istatshi sombona sivundiswa ziintsholongwane ukuvelisa i-polyhydroxybutyrate (PHB), oluluhlobo lwe-PHA. Ii-PHA eziqiniswe ngestatshi sombona zihlala zinozinzo olungcono lobushushu kunye neempawu zoomatshini. Ezi bioplastics zifumana ukusetyenziswa kumacandelo ahlukeneyo, kubandakanya ukupakisha, izixhobo zonyango, kunye nezolimo.

IiBioplastics Ezisekelwe Kwisitatshi: Kwezinye iimeko, isitatshi sombona sicutshungulwa ngqo sibe zii-bioplastics ngaphandle kwemfuneko yamanyathelo ongezelelweyo okwenza i-polymerization. Ii-bioplastics ezisekelwe kwisitatshi zihlala ziqulathe umxube wesitatshi sombona, iiplastiki, kunye nezongezo ukuphucula ukucutshungulwa kunye neempawu zokusetyenziswa ekugqibeleni. Ezi bioplastics zisetyenziswa kwizicelo ezifana neengxowa ezilahlwayo, izikhongozeli zokutya, kunye nezitya zokutya ezilahlwayo.

Ukudibanisa nezinye iiPolymers ezibolayo: Isitatshi sombona singadityaniswa nezinye iipolymers ezibolayo, ezifana ne-polyhydroxyalkanoates (PHA), i-polycaprolactone (PCL), okanye i-polybutylene adipate-co-terephthalate (PBAT), ukwenza ii-bioplastics ezineempawu ezilungiselelwe zona. Ezi ngxube zibonelela ngokulinganisela kwamandla oomatshini, ukuguquguquka, kunye nokubolayo, okwenza ukuba zilungele ukusetyenziswa ezahlukeneyo ukusuka ekupakishweni ukuya kwezolimo.

4. Isiphelo

Indima yesitatshi sombona kwi-bioplastics idlula ekuphuculeni ukusebenza; ikwanceda ekunciphiseni ukuxhomekeka kwiiplastiki zemveli ezisekelwe kwi-petroleum, nto leyo eqhuba uphuhliso lwezinto ezinobuhlobo nokusingqongileyo. Ngokuhambela phambili kwezobuchwepheshe, silindele ukubona iimveliso ezintsha ze-bioplastic ezisekelwe kwizixhobo ezivuselelekayo ezifana nesitatshi sombona.

Ngamafutshane, istatshi sombona sidlala indima ebanzi kwi-bioplastics, kungekuphela nje ukuphucula uzinzo lwesakhiwo seplastiki kodwa nokukhuthaza ukubola kwazo, ngaloo ndlela kunciphisa impembelelo yokusingqongileyo. Ngenkqubela phambili yetekhnoloji kunye nokuvelisa izinto ezintsha, ii-bioplastics zikulungele ukudlala indima enkulu ekuziseni iingenelo ezingakumbi kwindalo esingqongileyo yoMhlaba wethu.
