Gukomeza amabara, bizwi kandi nka "constantness of colour", bivuga kudahinduka kw'amabara cyangwa imyenda yacapwe mu gihe ihuye n'ibintu bitandukanye byo hanze nko kumesa, gukaraba, ibyuya, cyangwa gukaraba. Mu nganda z'imyenda, gusobanukirwa **constantness of colour** ni ingenzi cyane kugira ngo imyenda ikomeze kuba myiza kandi ihora igaragara neza uko igihe kigenda gihita. Iyi miterere ipima uburyo amarangi afatanye n'imigozi, ikarinda kuva amaraso, gusiba, cyangwa guhindura ibara. Waba uri umuguzi ugura imyenda iramba cyangwa uruganda rugamije ibicuruzwa byiza, "constantness of colour" igira uruhare runini mu mikorere myiza y'imyenda no kuramba kwayo.
Muri iyi mfashanyigisho, turasuzuma ibisobanuro by'uburyo amabara yihuta, akamaro kayo, ubwoko busanzwe, uburyo bwo gupima, n'inama zo kuyanoza mu myenda nk'ibikoresho biboshye. Mu kunoza ibintu nko gukoresha uburyo bwo koza no gukoresha uburyo bworoshye, ushobora guhitamo cyangwa gukora imyenda ihoraho igihe cyose.
Kuki kwihuta kw'amabara ari ingenzi mu myenda?
Kuramba no Kuramba:Imyenda ifite amabara meza cyane ihangana no kumesa kenshi, kwangirika no kwangirika kw'ibidukikije idatakaje ibara ryayo ry'umwimerere. Ibi ni ingenzi cyane cyane ku bikoresho bya buri munsi nk'imyenda, intebe zo mu nzu, n'imyenda yo mu rugo.
Kwirinda ibara n'amaraso:Kuba amabara adakomeye bishobora gutuma amarangi yimuka mu gihe cyo kumesa, bigatera amabara ku yindi myenda cyangwa ahandi hantu. Iki ni ikibazo gikunze kugaragara mu myenda myinshi ivanze, aho amabara yijimye ashobora kuva amaraso ku yoroshye.
Igenzura ry'ubuziranenge n'agaciro k'isoko:Imyenda ifite amabara yihuta cyane yujuje ibisabwa n’inganda n’ibyemezo, bigatuma agaciro kayo kagaragara. Ku bigo, ibi bituma inyungu zigabanuka, ibitekerezo byiza, no kubahiriza amabwiriza nka ISO cyangwa AATCC.
Gushora imari mu bikoresho bikoresha amabara menshi ntibyongera ubunararibonye bw'ababikoresha gusa, ahubwo binashyigikira imikorere irambye mu kugabanya gukenera gusimbuza kenshi.
Ubwoko busanzwe bw'ibizamini byo kwihuta kw'amabara
Uburyo bwo kwihuta kw'amabara si igitekerezo cy'uburyo bumwe bujyanye na byose; burimo uburyo butandukanye bwo guhangana n'ibintu bifatika. Dore ubwoko busanzwe, buri bumwe busuzumwa hakoreshejwe ibizamini bisanzwe:
Kwiyuhagira vuba:Ibi bipima uburyo amarangi yihanganira igihe cyo kumesa. Bigaragaza ko amarangi ahora ashira kugira ngo harebwe niba nta mabara ashira cyangwa ko nta ruhushya rujya mu myenda iri hafi aho. Ni byiza cyane ku myenda no ku buriri.
Kwihuta mu gukaraba (Gukubitagura):Ipima uburyo amabara adahinduka bitewe no gushwanyagurika, haba mu gihe cyumye cyangwa mu gihe cy'ubukonje. Ni ingenzi ku bikoresho nk'amapantalo cyangwa amatawulo ahora akorwaho.
Kwihuta byoroheje:Isuzuma ko izuba rizimira bitewe n'izuba cyangwa urumuri rw'ubukorano. Ni ingenzi ku myenda yo hanze, amarido, cyangwa imbere mu modoka aho imirasire ya UV ishobora kwangirika.
Kwihutira gusohora ibyuya:Isuzuma uburyo irangi rikora ku byuya by'abantu, birimo umunyu na aside. Ibi ni ingenzi cyane cyane ku myenda ya siporo n'imyenda ikora.
Izindi mpungenge zirimo uburyo bwo kwihuta mu byuya (ubwoko bw'ibyuya), uburyo bwo kwihuta mu mazi, n'uburyo bwo kwihuta mu byuma byo kogana. Kubyumva bifasha mu guhitamo imyenda ikwiye gukoreshwa mu buryo bwihariye.
Ni gute ibara ryihuse ripimwa kandi ripimwa?
Gupima kwihuta kw'amabara bikurikiza amahame mpuzamahanga nk'ay'Ishyirahamwe ry'Abanyamerika ry'Abahanga mu by'Imiti n'Amabara (AATCC) cyangwa Umuryango Mpuzamahanga wita ku Bipimo (ISO). Ubu buryo bukoresha ibikoresho byihariye kugira ngo byigane ingaruka mbi ku bidukikije no gupima umusaruro mu buryo buboneye.
Ibikoresho by'ingenzi byo gupima n'uburyo bwo kubipima:
Isuzuma ry'igipimo cy'imvi:Ikarita isanzwe y'ikijuju ikoreshwa mu kugereranya impinduka z'amabara mu buryo bw'ishusho. Irimo kuva kuri 1 (impinduka ikomeye) kugeza kuri 5 (nta mpinduka), itanga amanota yihuse kandi yizewe yo gusibangana cyangwa gusiga irangi.
Sisitemu yo gupima:Ibizamini byinshi bikoresha igipimo cya 1-5, aho 5 igaragaza ko umuvuduko mwiza (ibara ritagenda neza) naho 1 ikagaragaza ko nta musaruro mwiza (igabanuka rikomeye). Hari ibipimo by’inyongera bikoresha igipimo cya 1-8 kugira ngo hamenyekane ko umuvuduko woroheje ugenda ugabanuka.
Imashini zo gupima imyenda:Ibikoresho nka meseji (zo koza), crockmeters (zo gukaraba), n'amatara ya xenon arc (zo gukaraba) byigana imiterere nyayo. Ingero zirashyirwa ahagaragara, hanyuma zigasuzumwa kugira ngo hamenyekane niba amabara agumana hakoreshejwe spectrophotometers kugira ngo hapimwe neza.
Kugira ngo haboneke ibisubizo nyabyo, ibizamini bikorwa mu buryo bugenzurwa, akenshi muri laboratwari zemewe. Ibintu nk'ubwoko bw'imyenda (urugero: ipamba ugereranyije na polyester) na chimie y'irangi bigira ingaruka ku musaruro.
Inama zo kunoza uburyo amabara yihuta mu myenda iboshye
Ku myenda iboshywe, ikunze kugira ibibazo byo kunanura no gukurura irangi, kongera umuvuduko w'amabara bisaba guhitamo neza amarangi n'uburyo akoreshwa:
- Koresha amarangi akoreshwa mu gupima cyangwa mu gupima kugira ngo urusheho gufatana neza n'imigozi.
- Shyira imiti yo gusiga irangi mu gihe cyo gusiga irangi kugira ngo amabara akomeze kuba meza.
- Kurikiza amabwiriza yo kwita ku barwayi, nko gukaraba mu buryo bukonje no kumisha umwuka, kugira ngo bakomeze kwihuta.
- Hitamo imyenda yapimwe mbere y'uko igeragerezwa n'abayicuruza bazwi.
Niba urimo gukora imishinga yo kuboha imyenda yihariye, impuguke mu by'ubujyanama zishobora kugufasha gutunganya ibisubizo bihuye n'ibyo ukeneye.
Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) Ku bijyanye no Kwihuta mu Ibara
Ni ibihe bintu bigira ingaruka ku kwihuta kw'amabara?
Imiterere y'imyenda, ubwoko bw'irangi, uburyo ikorwamo, n'uburyo ikoreshwa mu kurengera ibidukikije byose bigira uruhare. Imyenda karemano nk'ipamba ishobora kugira urwego rwo kwihuta rutandukanye ugereranije n'iy'ibikoresho bya sintetike.
Ni gute napima ko ibara ryihuse mu rugo?
Ibizamini byoroshye birimo gusiga igitambaro gitose ku mwenda cyangwa gushyira icyitegererezo ku zuba, ariko ibizamini bya laboratwari by’umwuga birasabwa kugira ngo harebwe niba ari ukuri.
Ese kwihuta kw'amabara ni kimwe no kwihuta kw'amabara?
Yego, "colorfast" ikunze gukoreshwa mu buryo bumwe no kwihuta cyane kw'amabara, bivuze ko ibara ritazimira byoroshye.
Umwanzuro
Kumenya "kwihuta kw'amabara" biguha ubushobozi bwo gufata ibyemezo bifatika mu guhitamo no gukora imyenda. Kwihuta cyane bitanga imyenda irabagirana kandi iramba ihuye n'ibyo abaguzi bifuza ndetse n'amahame agenga inganda. Niba ushaka imyenda iboshye ihenze kandi ikora neza cyane cyangwa ukeneye inama z'inzobere, twandikire uyu munsi kugira ngo ubone ibisubizo byihariye.
Inama zo kunoza uburyo amabara yihuta mu myenda iboshye
Ku myenda iboshywe, ikunze kugira ibibazo byo kunanura no gukurura irangi, kongera umuvuduko w'amabara bisaba guhitamo neza amarangi n'uburyo akoreshwa:
- Koresha amarangi akoreshwa mu gupima cyangwa mu gupima kugira ngo urusheho gufatana neza n'imigozi.
- Shyira imiti yo gusiga irangi mu gihe cyo gusiga irangi kugira ngo amabara akomeze kuba meza.
- Kurikiza amabwiriza yo kwita ku barwayi, nko gukaraba mu buryo bukonje no kumisha umwuka, kugira ngo bakomeze kwihuta.
- Hitamo imyenda yapimwe mbere y'uko igeragerezwa n'abayicuruza bazwi.
Niba urimo gukora imishinga yo kuboha imyenda yihariye, impuguke mu by'ubujyanama zishobora kugufasha gutunganya ibisubizo bihuye n'ibyo ukeneye.
Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) Ku bijyanye no Kwihuta mu Ibara
Ni ibihe bintu bigira ingaruka ku kwihuta kw'amabara?
Imiterere y'imyenda, ubwoko bw'irangi, uburyo ikorwamo, n'uburyo ikoreshwa mu kurengera ibidukikije byose bigira uruhare. Imyenda karemano nk'ipamba ishobora kugira urwego rwo kwihuta rutandukanye ugereranije n'iy'ibikoresho bya sintetike.
