Ibicuruzwa bya kashe bikoreshwa cyane mukubaka inzugi nidirishya, urukuta rwumwenda, gushushanya imbere no gufunga ibikoresho bitandukanye, hamwe nibicuruzwa byinshi. Kugirango wuzuze ibisabwa bigaragara, amabara ya kashe nayo aratandukanye, ariko muburyo bukoreshwa, hazabaho ibibazo bitandukanye bijyanye namabara. Uyu munsi, Junbond azabasubiza umwe umwe.
Amabara asanzwe ya kashe yerekana amabara atatu yumukara, umweru nizuru.
Mubyongeyeho, uwabikoze azashyiraho andi mabara akunze gukoreshwa nkamabara ahamye kubakiriya bahitamo. Usibye amabara ahamye yatanzwe nuwabikoze, barashobora kwitwa ibara ridasanzwe (guhuza ibara) ibicuruzwa, mubisanzwe bisaba amafaranga yinyongera yo guhuza amabara. .
Kuki abakora amabara bamwe badashaka kuyikoresha?
Ibara rya kashe rituruka kuri pigment yongewemo mubiyigize, kandi pigment irashobora kugabanywamo pigment organic na pigment organic organique.
Byombi pigment organic na organic organique bifite ibyiza nibibi mugukoresha toni ya kashe. Mugihe bibaye ngombwa guhindura amabara meza cyane, nkumutuku, umutuku, nibindi, pigment organic igomba gukoreshwa kugirango igere kumabara. Kurwanya urumuri hamwe nubushyuhe bwo gutwika ibinyabuzima ni bibi, kandi ibicuruzwa bifunga kashe hamwe na pigment kama bizashira nyuma yigihe cyo kubikoresha, bigira ingaruka kumiterere. Nubwo bidahindura imikorere yikidodo, burigihe buribeshya kukibazo kijyanye nubwiza bwibicuruzwa.
Abantu bamwe batekereza ko bidakwiye ko ibara rizagira ingaruka kumikorere ya kashe. Mugihe utegura umubare muto wibicuruzwa byijimye, bitewe nubushobozi buke bwo gutahura neza ingano yibibara, igipimo cya pigment kizarenga igipimo. Umubare mwinshi wa pigment uzagira ingaruka kumikorere ya kashe. Koresha witonze.
Tone irenze kongeramo irangi. Nigute ushobora guhamagara ibara ryukuri nta kosa, nuburyo bwo kwemeza ko ibicuruzwa bihagaze neza hashingiwe ku guhindura ibara nibibazo ababikora benshi batarakemura.
Nk’uruganda runini rukora amarangi muri Aziya, Junbond ifite umurongo utera imbere cyane wo gutunganya amabara ku isi, ushobora guhindura neza kandi vuba ibara rihuye ukurikije ibyo abakiriya bakeneye.
Ni ukubera iki ibifatika byubatswe bidashobora guhindurwa?
Nkumurinzi wumutekano wurukuta rwumwenda wikirahure, ibifatika byubatswe bikoreshwa hagati yikariso hamwe nikirahure cyikirahure, bigira uruhare mugukosora imiterere, kandi mubisanzwe ntibisohoka, kubwibyo rero harakenewe bike cyane kubijyanye no gufata ibyuma bifatika.
Hariho ubwoko bubiri bwibikoresho byubaka: igice kimwe nibice bibiri. Ibice bibiri bigize ibice bifata neza muri rusange byera kubintu A, umukara kubice B, n'umukara nyuma yo kuvanga neza. Muri GB 16776-2005, harateganijwe neza ko ibara ryibice bibiri bigize ibicuruzwa bibiri bigomba kuba bitandukanye cyane. Intego yacyo nukworohereza kumenya niba ibifatika byubatswe bivanze neza. Ahantu hubatswe, abubatsi ntabwo bafite ibikoresho byumwuga bihuza ibikoresho, kandi ibice bibiri bigize ibara rihuza ibicuruzwa bishobora kugira ibibazo nko kuvanga kutaringaniye hamwe no gutandukanya amabara manini, bizagira ingaruka zikomeye kumikoreshereze yibicuruzwa. Kubwibyo, ibice bibiri bigize ibicuruzwa ahanini birabura, kandi mubihe bidasanzwe ni imvi.
Nubwo ikintu kimwe kigizwe nuburyo bufatika gishobora guhindurwa kimwe mugihe cyo gukora, imikorere yibicuruzwa byirabura niyo ihagaze neza. Ibikoresho byubaka bigira uruhare runini rwo gutunganya inyubako. Umutekano ni ngombwa kuruta umusozi wa Tai, kandi guhuza amabara muri rusange ntabwo byemewe.
