Peb lub tuam txhab tsim ntau yam xim acid. Peb cov xim acid muaj zog suav nrogAcid liab 14,Acid liab 18,Acid liab 73, thiab lwm yam.
Cov xim kua qaubmuaj cov qauv tshuaj yooj yim dua licov xim ncaj qhaQhov sib txawv no ua rau muaj ntau yam khoom siv zas xim thiab cov txheej txheem ntawm cov zas xim kua qaub. Yog li ntawd, cov zas xim kua qaub tuaj yeem muab faib ua plaub pawg: cov kua qaub muaj zog, cov kua qaub tsis muaj zog, cov kua qaub mordant thiab cov kua qaub sib xyaw.
Cov xim pleev uas muaj kua qaub (acid dyes) raug faib ua pawg raws li lawv cov tshuaj lom neeg thiab cov xwm txheej tshwj xeeb uas xav tau. Cov xim pleev uas muaj kua qaub ntau, raws li lub npe qhia, muaj kua qaub ntau dua thiab qhia txog cov yam ntxwv ntawm kev pleev uas muaj zog. Cov xim pleev no siv dav hauv ntau yam kev lag luam textile vim lawv muaj peev xwm muab cov xim ci thiab kav ntev.
Cov xim tsis muaj zog uas muaj kua qaub ntau, ntawm qhov tod tes, tsis muaj kua qaub ntau thiab ua rau cov xim tsis pom tseeb thiab mos dua. Cov xim no feem ntau siv rau hauv cov ntawv thov uas xav tau cov xim mos dua lossis tsis ci ntsa iab.
Tsis tas li ntawd xwb, muaj qee cov xim pleev uas siv cov ntsev hlau los ua kom lawv cov xim zoo nkauj dua. Cov xim pleev no ua rau cov xim ruaj khov thiab ua rau muaj ntau yam xim sib txawv, ua rau lawv haum rau cov kev siv tshwj xeeb.
Thaum kawg, cov xim acid compound yog cov qauv zoo ntawm cov xim acid thiab feem ntau siv thaum xav tau cov xim ci thiab cov qauv sib txawv. Cov xim no paub txog lawv cov xim zoo heev, ruaj khov thiab cov txheej txheem zas xim zoo heev.
Qhov ua tiav ntawm acid dye chromatography qhia txog qhov tseem ceeb ntawm kev nkag siab txog cov qauv molecular thiab cov khoom ntawm cov acid dyes sib txawv. Cov chaw tsim khoom textile thiab cov kws tshaj lij dyeing tam sim no tuaj yeem txiav txim siab tau zoo thaum xaiv cov acid dye zoo rau lawv cov kev xav tau tshwj xeeb. Ntxiv mus, qhov kev txhim kho no qhib qhov ua tau rau kev tshawb fawb ntxiv thiab kev nce qib hauv kev lag luam acid dyeing, lub hom phiaj yog txhim kho lub teeb thiab kev ua haujlwm ntub dej ntawm cov acid dyes. Zuag qhia tag nrho, qhov kev tawg tshiab hauv acid dye chromatography yuav pab txhim kho kev lag luam textile thiab txhim kho qhov zoo ntawm cov ntaub dyed.
