Kuki?Gutatanya NNOakazi?
Gutatanya NNOmolekile zirimo amatsinda mato hamwe nibice bihamye. Uruhare rwitsinda ryitsinda ni ugutanga imbaraga zihagije zihuza ibice byuzuza pigment. Molekile zitatanye ntizigwa hejuru yuduce, nicyo gisabwa kugirango abatatanye bakore. Igikorwa cyigice gihamye ni uguhindura pigment igiteranyo cya pigment ikwirakwizwa nimbaraga za mashini binyuze mumashanyarazi ya electrostatike no kurwanya umwanya mugice cyamazi kugirango wirinde ko ibice byegeranya.
Mu mashanyarazi kama, mugihe igice gihamye cyaGutatanya NNOituma uduce duto duto twatandukanijwe mukurwanya umwanya, mugihe intera yibice bitatanye iba ntoya kurenza ubunini bwurunigi rwumuti, urunigi rwumuti rukomatanya kandi entropie ikagabanuka. Mu mazi, ionisiyoneri ibaho hafi yitsinda rya ionic kugirango ikore ibice bibiri, kandi kwanga electrostatike birinda uduce duto duto. Niba idafite ionion polyether ihagaze neza, polyether ihindura uduce duto twa pigment yatatanye mukurwanya umwanya.
Muburyo bwo gukora impapuro nimpapuro, hakenewe umubare munini wimpapuro zikwirakwiza imiti kugirango zikemure ibibazo byo gutatanya, kugumana, kuyungurura nibindi. Kongera imiti ikwirakwiza imiti irashobora kugabanya fibre ihindagurika kandi bigatuma impapuro zoroha kandi zikora neza. Mubisanzwe, inyongeramusaruro zikoreshwa mugushungura kwa pulp, nka sida ya sida, kuyungurura, gutatanya, imiti ikomeza, imiti ifata ifuro, imiti igabanya ubukana, imisemburo y’ibinyabuzima, nibindi. Muri uru ruhererekane rwimyiteguro, bamwe ni abantu ku giti cyabo, bamwe baravanze, bafatanya hamwe kuzamura ireme ryurupapuro, kunoza neza umusaruro, kugabanya ibiciro byumusaruro.
Fibre nikintu cyingenzi kigira ingaruka kumiterere yimpapuro mugukora impapuro. Nka fibre ndende nimwe idahuye neza, gukora inyongeramusaruro, kuzuza nibindi kure yundi, hanyuma biragoye kubona imikorere imwe, imbaraga nziza zimpapuro. Ariko, hiyongereyeho gutatanya bikwiye, ubuso bwibice bikomeye birashobora gukora imiterere ya bimolecular, kandi nubushuhe bwubushuhe bwibice bikomeye birashobora kunozwa. Bimwe mu byiza byo gukwirakwiza fibre bisaba ibintu bimwe na bimwe bya pyrolytique, bishobora kunoza imikorere yo gukwirakwiza hamwe no kwiyongera kwubushyuhe. Noneho gabanya ububobere bwa pulp, utezimbere impapuro zoroshye kandi byoroshye.
