Okutegeeza:

1. aging agent rubber molecules with oxygen, ozone oxidation reaction, the structure of rubber was destroyed, so that the mechanical properties of the products reduced, shortened service life, this phenomenon is called the aging of rubber.Light and heat promote oxidation, which accelerates ageing.Add in the rubber can resist, slow down the aging of rubber products, called the aging agent.There are two types of anti-aging agents: physical and Chemical.Physical Anti - Ebirungo ebikaddiwa ye paraffin, wax, wax ne stearic acid, etc.Ebintu bino bisobola okukola firimu ku ngulu w’ebiva mu kapiira, okuziyiza oxygen oxidation ne molekyu za kapiira, naye era bisobola okuziyiza ekitangaala.Chemical anti-okukanga ebirungo ebikola oxygen mu ngeri ennyangu okusinga akapiira. Anti-Ekirungo ky’okukaddiwa okusooka n’okukendeeza ku kukwatagana wakati wa okisigyeni ne kapiira, ekiyinza okulwawo obulungi okukaddiwa.Okusinziira ku nsengekera ya molekyu, eddagala eriziyiza-okukaddiwa liyinza okwawulwamu amine, ketone amine, aldehyde amine, phenol n’ebiti ebirala {18} 3} 3} {18} {18} {18} {18} {18} 3} (n- phenyl - beta - naphthylamine) n'ebirala.

2. Okunyweza filler filler filler ekozesebwa okulongoosa amaanyi ga vulcanized rubber, rubber wear resistance, tear resistance ne elasticity.The reinforcing filler is mainly carbon black.Waliwo ebika 52 ebya kaboni omuddugavu ebikozesebwa mu makolero ga kapiira. Kikulu ekisookerwako mu makolero ga kapiira.

. Nga dibutyl phthalate, erongoosa obuziyiza bwa kapiira.Ebigonvu ebitera okukozesebwa bye bizigo eby’ebyuma, petroleum jelly, paraffin, kolaasi, coal tar, stearic acid ne rosin, n’ebirala.

4.Colorant colorant kye kintu ekivaako langi z’ebintu ebikolebwa mu kapiira.Ekirungo ekitali kya kiramu kiri langi etali ya kiramu, enjeru okutuuka ku titanium dioxide nga ekyuma ekisinga, eky’ekyuma ekimyufu, ekyuma ekimyufu eky’ekyuma, ekimyufu ekiziyiza, ekimyufu ekya kyenvu, bbululu alina ekibinja kya kiragala, ekirungo kya chromium chromium oxide ekiddugavu, langi enzirugavu ensengekera z’obutonde (organic colorants) ze langi ez’obutonde n’embala ezimu. Ebisinga ku langi zino biba bya barium oba calcium eby’ebirungo ebiramu, gamba nga ebimyufu nga biriko ekimyufu ekimyufu, ekya kyenvu nga biriko hanseatic G, kiragala nga biriko phthalic green, bbulu ne phthalic blue.
