Nkibikoresho fatizo byipine, reberi bivuga ibikoresho bya polymer byoroshye cyane kandi bigahinduka. Nibyoroshye mubushyuhe bwicyumba, irashobora kubyara deformations nini munsi yimbaraga ntoya yo hanze, kandi irashobora gusubira mumiterere yumwimerere nyuma yimbaraga ziva hanze. Rubber ni polymer amorphous rwose. Ubushyuhe bwikirahure bwabwo buri hasi kandi uburemere bwa molekuline akenshi ni bunini, burenga ibihumbi magana.
Rubber igabanijwemo ubwoko bubiri: reberi karemano na rubber. Rubber karemano ikorwa mugukuramo amase mubiti bya rubber, ibyatsi bya rubber nibindi bimera; reberi ya syntetique iboneka hamwe na polymerisation ya monomers zitandukanye.
Twese tuzi ko gushushanya reberi bifite ubushyuhe bwo hejuru. Mubisanzwe, kugirango harebwe uburyo bwiza bwo gukora reberi, uruganda rwa reberi rusanzwe rukoresha amashanyarazi yubushyuhe bwo hejuru kugirango ushushe kandi ushireho reberi.
Kubera ko reberi ari elastomer ishyushye, plastike ni elastomer ishyushye kandi ikonje. Kubwibyo, umusaruro wibicuruzwa bya reberi bisaba ubushyuhe bukwiye nubushyuhe buri gihe, bitabaye ibyo gutandukana mubyiza byibicuruzwa bishobora kubaho. Imashini itanga ibyuka igira uruhare runini muribi.
Umuntu wese wigeze guhura na reberi azi ko reberi ubwayo isaba inkunga yubushyuhe bwo hejuru kugirango ikorwe, kandi mugihe ikora ibicuruzwa bya reberi, birakenewe kandi gukoresha plastiki zishyushye kandi zishushe ubukonje, bisaba guhindura ubushyuhe mugihe cyo gukora. Imashini itanga ibyuka irashobora kugira uruhare muriki gikorwa. Ibicuruzwa byashizweho nuwabikoze birashobora kugera kubigenzura byubwenge kandi birashobora guhindura ubushyuhe nubushuhe ukurikije ibikoresho bitandukanye, bityo bigatuma umusaruro wibicuruzwa bya reberi uba mwinshi.
Imashini itanga amashanyarazi ntishobora gukomeza gusohora ubushyuhe bwo hejuru hamwe nubushyuhe bwa parike bugera kuri 171 ° C, bikwiranye rwose no gukora ibicuruzwa bya reberi.
