Madbacadaha kulaylka ayaa si weyn loo isticmaalaa, laakiin qof kastaa ma yaqaan sida ay u shaqeeyaan.Isku darkadaabacaha kulaylkaiyo warqad kuleyl ah ayaa xallin kara baahiyadeena daabacaadda maalinlaha ah.Haddaba sidee buu u shaqeeyaa daabacaha kulaylka?
Guud ahaan, walxaha kuleyliyaha semiconductor ayaa lagu rakibay madaxa daabacaadda ee daabacaha kulaylka.Madaxa daabacaadda ayaa kululaan doona marka uu shaqeynayo.Ka dib markaad la xiriirto warqad kuleyl ah, qaab ayaa la daabici karaa.Warqadda kulaylka waxaa lagu daboolay lakabka filimka hufan.daabacayaasha kulaylkaleeyihiin doorashooyin.Warqadda kuleylka ah ayaa lagu kululeeyaa meel gaar ah, iyada oo loo marayo kuleyl, fal-celin kiimikaad ayaa laga soo saaraa filimka si loo abuuro sawir, mabda'a wuxuu la mid yahay mashiinka fakiska.Kuleyliyeyaasha waxaa si macquul ah u maamula daabacaha qaab dhibco labajibbaaran ama strips.Marka la wado, garaaf u dhigma walxaha kuleyliyaha ayaa laga soo saarayaa warqadda kulaylka.
Waraaqaha kulaylka waa nooc gaar ah oo dahaaran warqad warshadaysan oo muuqaalkeedu la mid yahay warqadda cad ee caadiga ah.Dusha sare ee warqadda kulaylku waa siman tahay oo waxay ka samaysan tahay warqad caadi ah sida saldhigga warqadda, iyo lakabka lakabka koromophoric ee kulaylka ayaa lagu dahaadhay dusha warqadda caadiga ah.Waxaa loo yaqaan dheeha leuco), kaas oo aan kala soocin microcapsules, falcelinta kiimikaduna waxay ku jirtaa xaalad "daahsoon".Marka xaashida kulaylka ay la kulanto madaxa daabacaadda kulul, midabka horumariyaha midabka iyo dheeha leuco ee meesha uu madaxa daabacan ku daabaco kiimiko ahaan ayuu midab beddelaa si uu sawirro iyo qoraallo u sameeyo.
Marka warqadda kulaylka la dhigo deegaan ka sarreeya 70 ° C, dahaarka kulaylku wuxuu bilaabaa inuu beddelo midabka.Sababta midabkeedu sidoo kale wuxuu ka bilaabmaa halabuurka.Waxaa jira laba qaybood oo kulaylka ugu muhiimsan ee daahan warqad kuleyl ah: mid waa leuco dheeha ama leuco dheeha;Midda kale waa horumariye midabka.Noocan ah warqadda kulaylka waxaa sidoo kale loo yaqaannaa laba qaybood oo kiimiko ah warqad duubista kulaylka.
Inta badan loo isticmaalo sida midabada leuco waa: crystal violet lactone (CVL) ee nidaamka trityl phthalide, nidaamka fluoran, benzoylmethylene buluug (BLMB) aan midab lahayn ama nidaamka spiropyran.Sida caadiga ah loo isticmaalo sida wakiilada horumarinta midabka: para-hydroxybenzoic acid iyo esters (PHBB, PHB), salicylic acid, 2,4-dihydroxybenzoic acid ama sulfones aromatic iyo walxo kale.
Marka warqadda kulaylka la kululeeyo, dheeha leuco iyo horumariyaha ayaa si kiimiko ah uga falceliyaa si ay midab u soo saaraan, markaa marka warqadda kulaylka loo isticmaalo in lagu helo calaamadaha mashiinka fakiska ama si toos ah ugu daabacdaabacaha kulaylka, garaafyada iyo qoraalka waa la soo bandhigay.Maadaama ay jiraan noocyo badan oo leuco ah, midabka farta la soo bandhigay waa ka duwan yahay, oo ay ku jiraan buluug, guduud, madow iyo wixii la mid ah.
