Tsis tas li ntawd, nws cov khoom ua kom qhuav sai ua rau nws zoo tagnrho rau cov txheej txheem ntoo staining.
Lwm daim ntawv thov tseem ceeb ntawm cov kuab tshuaj dyes yog hauv kev lag luam luam ntawv. Cov dyes no feem ntau yog siv los tsim cov ntawv zoo nkauj thiab zoo rau kev luam ntawv. Lub solubility ntawm cov kuab tshuaj dyes ua rau lawv yooj yim los sib xyaw nrog cov kuab tshuaj sib xws, uas ua rau kom zoo-dispersed thiab ceev-drying inks. Qhov no ua rau cov txheej txheem luam ntawv du thiab meej hauv ntau yam kev lag luam xws li ntim, luam tawm thiab textiles.
Cia peb tam sim no delve rau hauv cov yam ntxwv uas ua rau hnyav dyes sawv tawm. Ib qho tseem ceeb feature yog nws zoo heev lub teeb ceev ceev, uas ua kom cov xim nyob twj ywm vibrant thiab fade-resistant txawm thaum raug tshav ntuj los yog lwm yam ntaub ntawv ntawm UV hluav taws xob. Cov cuab yeej no tseem ceeb heev rau cov ntawv thov uas yuav tsum tau khaws cov xim mus ntev, xws li cov khoom siv yas sab nraum zoov lossis cov xim pleev xim.
Cov kuab tshuaj dyes kuj muaj cov tshuaj tiv thaiv siab, ua rau lawv haum rau kev lag luam uas nquag raug rau cov tshuaj hnyav, xws li tsheb lossis cov txheej txheem. Lawv tuav cov xim kev ncaj ncees txawm nyob rau hauv kev sib cuag nrog cov kuab tshuaj, roj los yog acids, kom ntseeg tau ib tug ntev-ntev, ruaj tiav.
Tsis tas li ntawd, cov kuab tshuaj dyes muaj cov thermal stability zoo, ua rau lawv tsim nyog rau cov ntawv thov uas muaj qhov kub thiab txias. Qhov no feature tshwj xeeb tshaj yog pab tau nyob rau hauv cov txheej txheem yas molding los yog thaum tha xim cov khoom uas tej zaum yuav raug tshav kub.
Hauv kev xaus, hnyav dyes yog ntau yam xim uas tau siv dav hauv ntau yam lag luam. Lawv siv nyob rau hauv plastics thiab painting industries tuaj yeem ua rau cov khoom zoo nkauj thiab pom kev zoo.
