Ngaba i-cellulose yi-polymer yendalo okanye eyenziweyo?

I-Celluloseyipolymer yendalo, into ebalulekileyo eludongeni lweeseli kwizityalo. Yenye yezona zinto zininzi eziphilayo emhlabeni kwaye isebenza njengezinto zokwakha kubukumkani bezityalo. Xa sicinga nge-cellulose, sihlala siyidibanisa nobukho bayo emthini, kumqhaphu, ephepheni, nakwezinye izinto ezahlukeneyo ezivela kwizityalo.

Ulwakhiwo lwe-cellulose luqulathe imixokelelwane emide yeemolekyuli zeglucose ezidityaniswe kunye ngeebhondi ze-beta-1,4-glycosidic. Ezi mixokelelwane zihlelwe ngendlela evumela ukuba zenze izakhiwo eziqinileyo, ezinemisonto. Ulungiselelo olulodwa lwale mixokelelwane lunika i-cellulose iimpawu zayo ezimangalisayo zoomatshini, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo yokubonelela ngenkxaso yesakhiwo kwizityalo.

Inkqubo yokwenziwa kwe-cellulose kwizityalo ibandakanya i-enzyme cellulose synthase, epholisha iimolekyuli zeglucose zibe ziitsheyini ezinde ize izikhuphele eludongeni lweseli. Le nkqubo yenzeka kwiintlobo ngeentlobo zeeseli zezityalo, inegalelo ekuqineni nasekuqineni kwezicubu zezityalo.

Ngenxa yobuninzi bayo kunye neempawu zayo ezikhethekileyo, i-cellulose ifumene izicelo ezininzi ngaphaya kwendima yayo kwibhayoloji yezityalo. Amashishini asebenzisa i-cellulose ukuvelisa iphepha, amalaphu (njengekotoni), kunye neentlobo ezithile ze-biofuels. Ukongeza, izinto eziphuma kwi-cellulose ezifana ne-cellulose acetate kunye ne-cellulose ethers zisetyenziswa kwiimveliso ezahlukeneyo, kubandakanya amayeza, izongezo zokutya, kunye neengubo.

Ngelixai-cellulosengokwayo yipolymer yendalo, abantu baye baphuhlisa iinkqubo zokuyiguqula nokuyisebenzisa ngeendlela ezahlukeneyo. Umzekelo, unyango lweekhemikhali lunokutshintsha iipropati zayo ukuze lufaneleke ngakumbi kwizicelo ezithile. Nangona kunjalo, nakwiindlela eziguquliweyo, i-cellulose igcina imvelaphi yayo yendalo esisiseko, nto leyo eyenza ukuba ibe yinto eguquguqukayo nexabisekileyo kwiimeko zendalo nezenziwe ngobunjineli.
