Kuzimya ibirahuri ni ugushyushya ibicuruzwa byikirahure kubushyuhe bwinzibacyuho T, hejuru ya 50 ~ 60 C, hanyuma ukayikonjesha byihuse kandi kimwe muburyo bukonje (uburyo bwo kuzimya) (nko kuzimya ikirere gikonje, kuzimya amazi akonje, etc. Imbaraga nyazo zikirahure ziri hasi cyane kurenza imbaraga zamahame. Ukurikije uburyo bwo kuvunika, ikirahure gishobora gushimangirwa no gukora urwego rwo guhagarika umutima hejuru yikirahure (bizwi kandi ko ari ubushyuhe bwumubiri), ibyo bikaba ari ingaruka ziterwa nubukanishi bugira uruhare runini.
Nyuma yo gukonjesha, ubushyuhe bwa gradient bugenda busibangana buhoro buhoro, kandi guhangayika kuruhutse bigahinduka imihangayiko myiza, bikavamo igabanywa rimwe ryoguhagarika umutima hejuru yikirahure. Ubunini bwiyi mihangayiko yimbere bujyanye nubunini bwibicuruzwa, igipimo cyo gukonja hamwe na coefficient yo kwaguka. Kubwibyo, byizerwa ko mugihe ikirahure cyoroshye nikirahure hamwe na coefficient yo kwaguka bigoye cyane kuzimya ibicuruzwa byibirahure byazimye, ibintu byubaka bigira uruhare runini; , ni ibintu bya mehaniki bigira uruhare runini. Iyo umwuka ukoreshejwe nk'uburyo bwo kuzimya, byitwa kuzimya ikirere; iyo amazi nkamavuta, amaboko ya silicon, paraffin, resin, tar, nibindi bikoreshwa nkuburyo bwo kuzimya, byitwa kuzimya amazi akonje. Mubyongeyeho, umunyu nka nitrate, chromates, sulfate, nibindi bikoreshwa nkibizimya itangazamakuru. Icyuma kizimya icyuma ni ifu yicyuma, icyuma cyoroshye cyoroshye brush, nibindi.
