Kambani yedu inogadzira madhayi akasiyana-siyana eacid. Madhayi edu eacid akasimba anosanganisiraAsidhi tsvuku 14,Asidhi tsvuku 18,Asidhi tsvuku 73, nezvimwewo.
Madhayi easidhivane chimiro chemakemikari chiri nyore kupfuuramadhayi akanangaMusiyano uyu unotungamira kune hunhu hwakasiyana-siyana hwekudhaya uye nzira dzekushandisa madhayi ane acid. Nokudaro, madhayi ane acid anogona kukamurwa muzvikamu zvina: strong acid, weak acid, acid mordant uye acid complex dye.
Madhayi ane acid anorongwa zvakanyanya zvichienderana nemakemikari aanoita uye mamiriro chaiwo ekudhaya anodiwa. Madhayi ane acid yakasimba, sezita rinoratidza, ane acid yakawanda uye anoratidza hunhu hwakasimba hwekudhaya. Madhayi aya anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana emachira nekuda kwekugona kwawo kupa mavara akasimba uye anogara kwenguva refu.
Kune rumwe rutivi, madhayi easidhi asina kusimba haana asidhi yakawanda uye anoita kuti dhayi ive yakapfava uye ine hunyoro. Madhayi aya anowanzo shandiswa muzvinhu zvinoda ruvara rwakapfava kana rusina kujeka zvakanyanya.
Pamusoro pezvo, kune mamwe madhayi ane acid mordant anoshandiswa nerubatsiro rwesimbi munyu kuti awedzere kunaka kwekudhaya. Madhayi aya anovandudza kusimba kwemavara uye anobvumira kusiyana kwemavara, zvichiita kuti akwanise kushandiswa zvakasiyana.
Chekupedzisira, madhayi ane acid compound imhando dzakanatswa dzemadhayi ane acid uye anowanzo shandiswa kana paine mavara akasimba uye mapatani akaomarara. Madhayi aya anozivikanwa nekukasika kwawo kwemavara, kugara kwenguva refu uye nzira dzawo dzakaoma dzekudhaya.
Kubudirira kwekugadzirwa kweacid dye chromatography kunoratidza kukosha kwekunzwisisa chimiro chemamorekuru uye hunhu hwemadhayi akasiyana eacid. Vagadziri vemachira nenyanzvi dzekudhaya vanogona kuita sarudzo dzine ruzivo pavanenge vachisarudza acid dye yakakodzera zvavanoda. Uyezve, budiriro iyi inovhura mukana wekuwedzera tsvakurudzo nekufambira mberi mumunda wekudhaya acid, nechinangwa chekuvandudza kusimba uye kukurumidza kwekugadzirisa kweacid dyes. Kazhinji, kubudirira uku muacid dye chromatography kuchabatsira kuvandudza indasitiri yemachira uye kuvandudza mhando yemachira akadhayiwa.
