Ikirere: Urufunguzo rwa Firime Zirinda Zirinda
Mubikorwa byinshi biranga firime ikingira (viscosity, umubyimba, ibara, elastique, transmitance, nibindi) Imwe murimwe nubushobozi bwikirere, bivuze ko firime yikirere iri mukurwanya ibidukikije; ni ukubera iki ari firime ikingira gushimangira iyi miterere? Kwambara kwa firime bigira ingaruka zikomeye kumiterere ya firime ikingira.
Filime ikingira mugukoresha uburyo bwo kurinda ibicuruzwa byarangiye birasabwa kandi guhura nizuba bitaziguye, bikenera amezi atandatu kugeza kumwaka umwe cyangwa muribwo buryo muri rusange ntibibaho mugihe cyangiritse kuri firime ikingira, ariko hazabaho impinduka mubikorwa. Irashobora kandi gufatirwa muri kontineri hakurya y'inyanja amezi make. Ibidukikije birinda firime birinda birakaze.
Filime ikingira ifite imikorere yubukorikori nziza kandi irahuye cyane nibisabwa n’umukoresha kugirango akomere cyane, modulus ya elastique, kuramba, nibindi. murwego rwo kohereza ibintu no gutunganya, firime ikingira ntishobora gukomera cyangwa kugwa.
Filime ikingira ifite ibihe byiza byo guhangana nikirere no guhagarara neza; kurenza iminsi mike cyangwa umwanya muremure wo gukomera hamwe nimbaraga zo gukuramo ntibizagira ubwiyongere bugaragara, byoroshye kugwa, kandi bitavumbuwe mugihe isura irinzwe itazasiga ibimenyetso bisigaye, ntizisiga igicucu. (Ku rundi ruhande, ni n'ubwoko bwo kurinda)
Filime yo gukingira yakoreshejwe igihe runaka nyuma yikigo cyayo kimaze kugaragara, ariko impande zombi zihengamye. Impamvu nini yibi bintu nuko firime irinda imyirondoro ikoreshwa mugushiraho impagarara nyinshi hanyuma ikaza guhura nubushyuhe bwo hejuru bizaba ibintu bidakenewe kugabanuka.
Filime ikingira iki kibazo iboneka cyane mugihe cyizuba nimvura, bityo firime ikingira mugikorwa cyo kuyikora igomba kwitondera itandukaniro ryubushyuhe bwibidukikije ku ngaruka zikoreshwa ryibicuruzwa. Kugirango wirinde gufata amashusho, hariho isura idakenewe yo kurambura.
