Ibinyabuzima bishobora kwangirika bishobora guhindura inganda zo kwisiga.

Ubuzima bwuzuye ibintu bipfunyitse, amacupa yo kwisiga, ibikombe byimbuto nibindi byinshi, ariko ibyinshi muri byo bikozwe mubikoresho byuburozi kandi bidashoboka bigira uruhare mukwangiza plastike.

Vuba aha, abashakashatsi bo muri kaminuza ya Cambridge mu Bwongereza babonye uburyo bwo gukora glitteri irambye, idafite ubumara kandi ibora ibinyabuzima biva muri selile, igice kinini cyubaka urukuta rw'utugari rw'ibimera, imbuto n'imboga. Impapuro zijyanye nazo zasohotse mu kinyamakuru Nature Materials ku ya 11.

Ikozwe muri selile ya nanocrystal, iyi glitter ikoresha ibara ryimiterere kugirango ihindure urumuri kugirango rutange amabara meza. Muri kamere, nk'urugero, amababa y'ibinyugunyugu n'amababa ya pawusi ni ibihangano by'amabara yubatswe, bitazashira nyuma yikinyejana.

Abashakashatsi bavuga ko ukoresheje tekinike yo kwiteranya, selile irashobora gukora firime zifite amabara meza. Mugutezimbere igisubizo cya selile hamwe nibipimo byo gutwikira, itsinda ryubushakashatsi ryashoboye kugenzura byimazeyo gahunda yo kwiteranya, bituma ibikoresho bikorerwa cyane mumuzingo. Inzira zabo zirahuye nimashini zisanzwe zinganda. Ukoresheje ibikoresho bya selile biboneka mubucuruzi, bisaba intambwe nke gusa kugirango uhindure ihagarikwa ririmo iyi glitter.

Nyuma yo gukora firime ya selile murwego runini, abashakashatsi babishyira mubice bingana nabyo bikoreshwa mugukora glitter cyangwa gukora pigment. Pellet irashobora kubora, idafite plastike, kandi ntabwo ari uburozi. Ikigeretse kuri ibyo, inzira ni nkeya cyane imbaraga nyinshi kuruta uburyo busanzwe.

Ibikoresho byabo byashoboraga gukoreshwa mugusimbuza uduce duto twa plastike hamwe nuduce duto twa minerval ikoreshwa cyane mu kwisiga. Ibara rya gakondo, nk'ifu ya glitteri ikoreshwa mugukoresha burimunsi, ni ibikoresho bidashoboka kandi bihumanya ubutaka ninyanja. Muri rusange, imyunyu ngugu ya pigment igomba gushyukwa ku bushyuhe bwo hejuru bwa 800 ° C kugirango ibe ibice bya pigment, nabyo bikaba bidahuye nibidukikije.

Filime ya selulose nanocrystal yateguwe nitsinda irashobora gukorwa ku rugero runini hakoreshejwe uburyo bwa "roll-to-roll", kimwe nimpapuro zikozwe mu mbaho ​​zimbaho, bigatuma iyi nganda yibikoresho byambere.

Mu Burayi, inganda zo kwisiga zikoresha toni zigera ku 5.500 za microplastique buri mwaka. Umwanditsi mukuru w’uru rupapuro, Porofeseri Silvia Vignolini, wo mu ishami rya Yusuf Hamid ishami ry’ubutabire muri kaminuza ya Cambridge, yavuze ko bizera ko ibicuruzwa bishobora guhindura inganda zo kwisiga.
