Kwambiri kupanga mitundu chakudya kugwa mu gulu ili.

Kuweta utoto

utoto Basic ndi madzi sungunuka cationic utoto amene kwenikweni amatanthauza ulusi akiliriki, koma nditapeza ntchito ubweya, silika. Kawirikawiri asidi acetic anawonjezera kuti utoto kusamba kuthandiza kutengedwa wa utoto kumtunda usasungunuke. utoto Basic amagwiritsidwa ntchito mu coloration pepala.

moŵa utoto

Moŵa utoto ali kwenikweni insoluble m'madzi ndipo sangathe ankaudaya ulusi mwachindunji. Komabe, kuchepetsa mowa zamchere umabala madzi sungunuka ndi soda zitsulo mchere wa utoto. fomu iyi zambiri colorless, mu nkhani imene akutchulidwa monga Leuco utoto, ndipo ali kuyandikana kwa CHIKWANGWANI nsalu. kusintha wotsatira makutidwe ndi okosijeni choyambirira insoluble utoto. Mtundu wa chi chifukwa enaake, choyambirira moŵa utoto.

Iwo ntchito monga zizindikiro pH ndipo Madontho kwachilengedwenso.

sulfa utoto

Sulfa nsalu ndi utoto yotchipa ntchito utoto thonje ndi mitundu mdima. Ankaudaya ndi kunatheka chifukwa Kutentha nsalu mu njira ya pawiri wopanda feteleza, ambiri ndi nitrophenol otumphukira, ndi sulfide kapena polysulfide. Pawiri organic amachitira ndi gwero sulfide kupanga mitundu mdima kuti kutsatira nsalu. Sulfa Black 1, yaikulu kugulitsa utoto ndi buku, alibe bwino kumatanthauza dongosolo mankhwala.
