Kufotokozera
Direct wakuda EX ndi utoto wachindunji, mu mawonekedwe a ufa wakuda kwambiri, ukhoza kusungunuka mwachindunji m'madzi, molekyuluyo imakhala ndi gulu la sulfonic acid, imatha kupakidwa utoto mwachindunji pamikhalidwe yopanda ndale pa ulusi wa cellulose, imakhala ndi kuwongolera kwakukulu kwa cellulose, popanda kugwiritsa ntchito. njira za mankhwala.M'makampani opanga nsalu nthawi zambiri amagwiritsidwa ntchito popaka utoto wachilengedwe, monga ubweya, silika, komanso amagwiritsidwa ntchito mu thonje, hemp, silika wa rayon, utoto wa thonje wa rayon.
Makhalidwe a malonda
Mawonekedwe a Direct black EX akuphatikiza:
Maonekedwe athupi: Direct wakuda EX ndi utoto wa ufa womwe umasungunuka m'madzi.
Kapangidwe ka mankhwala: ufa wakuda wakuda wosungunuka m'madzi ndi wobiriwira wobiriwira wakuda, wosungunuka pang'ono mu ethanol, wobiriwira wobiriwira wakuda wabuluu, wosungunuka mu lysofibrin, wosasungunuka mu zosungunulira zina.Mu nkhani ya anaikira sulfuric asidi kwambiri wofiira buluu, pambuyo dilution ndi wofiirira phala mtundu wofiira wakuda mpweya;Njira yachikasu yofiirira mu asidi wa nitric woyikira;Njira yakuda yofiyira-kuwala kwakuda mu concentrated hydrochloric acid.Yake amadzimadzi njira ndi anaikira hydrochloric asidi anali precipitated purplish mtundu.Pamene concentrated sodium hydroxide solution iwonjezeredwa, mpweya wa imvi umapangidwa.Pakupaka utoto wa cellulose, kuyamwa kwa utoto ndikwabwino kwambiri, kuyanjana kwakukulu ku 80 ℃.Kudaya kungatheke.
Kagwiritsidwe: Ntchito dyeing CHIKWANGWANI, thonje, hemp, rayon silika ndi rayon thonje ndi zina zotero.

Utoto wa A.Direct umagwiritsidwa ntchito kwambiri podaya thonje ndi ulusi wa viscose.
B. Mtundu uwu wa utoto umakhala wolunjika kwambiri ku ulusi wa cellulose ndipo ukhoza kupakidwa utoto mwachindunji.
C. Mitundu yachindunji ndi yotsika mtengo, yosavuta yopaka utoto, chromatography yathunthu, mtundu wowala, choyipa ndichakuti kuthamangitsidwa konyowa kwa utoto sikuli koyenera, nthawi zambiri kudzera mukukonzekera chithandizo chamankhwala kuti chiwongolere, kufulumira kwa kuwala kwa dzuwa kumasiyana kwambiri ndi mitundu ya utoto.
