Plastiki irashobora kubaho mwisi yisi mumyaka 1000, ariko ikirahure gishobora kubaho igihe kirekire, kubera iki?

Kubera kwangirika gukomeye, plastike ihinduka umwanda ukomeye.Niba ushaka ko plastiki iba iyangirika ryisi kwisi, ukenera imyaka 200 ~ 1000.Ariko ibindi bikoresho birakomeye kuruta plastiki, kandi bibaho igihe kirekire, ni ikirahure.

Hafi yimyaka 4000 ishize, umuntu yashoboraga gukora ibirahure.Kandi hashize imyaka 3000, Abanyamisiri ba kera bafite ubuhanga bwo kuvuza ibirahuri.Ubu ibicuruzwa byinshi byibirahure mubihe bitandukanye tubisanga na archeologue, kandi bikabikwa neza, ibi byerekanaga ko imyaka ijana nta ngaruka igira ku kirahure.Niba ari birebire, ni izihe ngaruka?

Ibyingenzi byingenzi byikirahure ni silika nizindi oxyde, ntabwo ari kristu ikomeye ifite imiterere idasanzwe.

Mubisanzwe, gahunda ya molekuline ya fluid na gaze birahungabana, kandi kubikomeye, biratondekanye.ikirahure kirakomeye, ariko gahunda ya molekuline ni nkamazi na gaze.Kubera iki?Mubyukuri, atome itunganijwe yikirahure idahwitse, ariko niba witegereje atome umwe umwe, ni atome imwe ya silicon ihuza na atome enye za ogisijeni.Iyi gahunda idasanzwe yitwa "urutonde ruto".Niyo mpamvu ikirahure gikomeye ariko cyoroshye.

Iyi gahunda idasanzwe ikora ikirahure gifite ubukana buhebuje, icyarimwe, umutungo wimiti wikirahure urahagaze neza, hafi ya nta reaction yimiti iri hagati yikirahure nibindi bikoresho.Biragoye rero kubora kubirahuri kwisi.

Ikirahure kinini cyacitsemo uduce duto twibasiwe, hamwe nibindi bitero, uduce duto twaba duto, ndetse tukaba duto kuruta umusenyi.Ariko iracyari ikirahure, ikirahure cyacyo kavukire ntikizahinduka.

Ikirahuri rero gishobora kubaho mwisi karemano imyaka irenga ibihumbi.
