I-Keratin, into efanelekileyo yeprotheni yokusetyenziswa kwiiprinta ze-3D

Keratin

Ngokuqinisekileyo ukuba ungumntu othanda ukomelela komzimba okanye uyayithanda imidlalo kwaye uhlala uyenza rhoqo, ngokuqinisekileyo ngamanye amaxesha ukhe weva ngento enje keratin njengoko ihlala isetyenziswa kwezempilo nakwimveliso ye cosmetology. Kwelinye icala, inyani yokuba isetyenziselwa olu hlobo lwemveliso ayithethi ukuba ayiboneleli ngezinye iintlobo zoncedo, kwimeko ethile yekeratin, ikwasetyenziselwa ukuphelisa ukungcola okukhoyo emanzini nakwindawo uphuhliso lwezixhobo ze-polymeric.

Ngale nto engqondweni, namhlanje ndifuna ukuba sithethe ngophando lwakutsha nje olwenziwe ngabaphandi abavela kwiSebe leZinto eziPhambili kunye neNanotechnology ye Iziko iTecnológico de Querétaro ngokudibeneyo zilawulwa ziingcali uAna Laura Martínez Hernández noCarlos Velasco Santos, apho baphanda khona iipropathi ezinikezelwa ngokufakwa kwekeratin kwizinto ezahlukeneyo zokwenziwa ezinjengepolymethylmethacrylate, polypropylene, polyurethanes ...

Ukusetyenziswa kwekeratin xa kusenziwa intambo yokuprinta i-3D kunokuzisa izibonelelo ezininzi

Njengomnye wabathetheli beqela lophando ucacisa:

Sisebenzise le keratin kwizicelo ezinje ngemveliso yezinto ezisekwe kwipolymer. Iyahambelana kakhulu ne-polymer eyenziweyo ngenxa yendalo yayo ye-hydrophobic, Oko kukuthi, ukugxotha amanzi. Oku kuququzelela ukusasazeka kwemicu kunye nematriki. Sikwaqulunqa izinto ezenziwa ngokuprinta i-3D nge-polylactic acid matrix kunye nokuqiniswa kwezinto zekeratin notshintsho olufanelekileyo kwiipropathi zethemomechanical kunye nokuqhutywa kwe-thermal.

Into esasiyifuna yayikukuqinisa izinto zendalo, ezinje ngesitatshi samazambane kunye ne-crustacean chitosan ngale keratin. Kuqala besisebenza kwilabhoratri emva koko kwinqanaba le-semi-industrial, sisebenzisa i-extrusion ukuthelekisa iipropathi ezonyuke ukuya kuthi ga kumawaka amabini epesenti. Kwi-post-doctorate ndisebenzisa i-polylactic acid (i-PLA) kunye ne-keratin kwi-3D yokuprinta kodwa ngoku ngeenwele zomvundla.

Siphinda sifunde ukuba luncedo kwonyango lwamanzi amdaka; Ngale ndlela, i-keratin inamaqela asebenzayo avela kwii-amino acid, ziindawo apho izinto ezingcolisayo ezahlukeneyo ezinje ngesinyithi esinzima zilungisiwe, kubandakanya i-hexavalent chromium (Cr), lead (Pb), nickel (Ni) kunye neehydrocarbon.

Izinto zekhabhoni kwiinguqu zazo ezine-oxidized kunye ne-crude, kunye nokusebenza namanye amaqela eekhemikhali kunye neetyathanga ezinkulu zisetyenzisiwe kuphuhliso lwee-composites, nanocomposites, multiscale and multidimensional composites in polymeric matrices apho iipolymer ezinje ngeepoxies zisetyenzisiwe. Inayiloni, chitosan -isitatshi kunye ne-polylactic acid, eqhutywa yaze yahlanganiswa ngeendlela ezahlukeneyo ukusukela ekuphoseni, inaliti, extrusion, ukushicilelwa kwe-3D, ukubethelwa kombane kunye nokunyanga kwindawo, inezinto ezishushu, zombane kunye nezoomatshini, kuxhomekeke kwimatriki esetyenzisiweyo.
