Ibyerekeye Umuhondo R.

Umuhondo R.ni irangi ryimiti rikoreshwa cyane mubikorwa byo gucapa no gusiga amarangi. Nibimwe murirangi rya azo kandi bifite irangi ryiza ryo gusiga no gutuza. Direct Yellow R ikoreshwa cyane mumyenda, uruhu, impapuro nizindi nganda mubushinwa. Ariko, gukoresha umuhondo R utaziguye ugomba kwitondera kurinda umutekano kugirango wirinde ingaruka mbi kubidukikije no kumubiri wumuntu.
Umusaruro wumuhondo R utaziguye urimo intambwe eshatu: synthesis, kweza no gusiga irangi. Muri synthesis, uburyo bwo kubyitwaramo bugomba kugenzurwa cyane kugirango isuku irangwe neza. Igikorwa cyo kweza gisaba tekinike nziza yo gutandukana kugirango ikureho umwanda nibindi bintu byangiza. Mugihe cyo gusiga irangi, umuhondo R utaziguye urashobora gufata imiti hamwe nibikoresho bya fibre kugirango ikore ikiyaga cyamabara gihamye, kugirango tumenye irangi ryimyenda, uruhu nibindi bikoresho.
Umuhondo R.ifite irangi ryiza, rishobora gukora ibintu bisize irangi byerekana amabara meza kandi arambye. Byongeye kandi, ifite kandi imbaraga zo gukemuka no gutatanya, biroroshye gutatanya neza mumazi cyangwa andi mashanyarazi, kandi byoroshye gusiga irangi. Umuhondo ugororotse R ufite kandi urumuri rwiza, kurwanya amazi no kurwanya ubukana, kuburyo ibintu bisize irangi bitoroshye gucika no kwambara mugihe cyo gukoresha. Nyamara, umuhondo utaziguye R nayo ifite umutekano muke mugikorwa cyo gukoresha. Kuberako irimo imiterere ya azo, mubihe bimwe bishobora kurekura imyuka yubumara, bigatera kwangiza umubiri wumuntu nibidukikije.

Muri icyo gihe, amarangi y’imyanda agomba gutabwa neza kugirango hirindwe ibidukikije.
Muri make,umuhondo R., nk'irangi ryingenzi ryimiti, rifite uburyo bwinshi bwo gukoresha mubikorwa byo gucapa no gusiga amarangi.
