Mitundu ya Acid

Hermeta Acid Dyes nthawi zambiri amagwiritsidwa ntchito ku nsalu zotsika pH.Amagwiritsidwa ntchito makamaka popaka ubweya wa ubweya, osati nsalu za thonje.

Utoto wa asidi ndi anionic, umasungunuka m'madzi ndipo umagwiritsidwa ntchito kuchokera kumadzi a acidic.Utoto uwu uli ndi magulu a acidic, monga SO3H ndi COOH ndipo amagwiritsidwa ntchito pa ubweya, silika ndi nayiloni pamene mgwirizano wa ionic umakhazikitsidwa pakati pa protonated -NH2 gulu la fiber ndi gulu la asidi la utoto.Kuthamanga kwapang'onopang'ono kumakhala koyipa ngakhale kupepuka kumakhala kwabwino.Popeza utoto ndi ulusi zimakhala ndi mphamvu zosiyana ndi magetsi, kugunda ndi kutulutsa utoto wa asidi pa ulusiwu kumathamanga;ma electrolyte omwe ali pamwamba kwambiri amawonjezeredwa kuti atengeke pang'onopang'ono utoto ndikupanga mithunzi yokhazikika.Acid imapanga cation pa fiber ndi kutentha kumathandiza kuti m'malo mwa asidi asokonezeke ndi ma molekyulu a utoto wa anionic.
