Direct Yellow R

Direct yellow Ramatchedwanso udzu wolunjika wachikasu ndiyellow yellow 2G.Maonekedwe ake ndi ufa wofiirira wa yunifolomu, womwe umakhala wofiira ndi wachikasu ukasungunuka m'madzi, umasungunuka pang'ono mu fibrinolysin komanso wosasungunuka mu zosungunulira zina.Ndi yofiyira yofiyira mu sulfuric acid yokhazikika ndipo imasanduka yachikasu chakuda ikatha kuchepetsedwa (nthawi zina imatulutsa mpweya wofiirira);Pang'ono kusungunuka moyikira nitric asidi akutembenukira chikasu kuwala bulauni kuti azitona mtundu, ndi pang'ono kusungunuka mu anaikira hydrochloric asidi akutembenukira wakuda.Direct Yellow RNjira yamadzimadzi ndi yachikasu ya azitona yokhala ndi hydrochloric acid ndi lalanje wagolide wokhala ndi sodium hydroxide.Kuwala kwamtundu kumakhala kobiriwira mukakumana ndi ayoni amkuwa, chikasu choderapo pang'ono pokumana ndi ayoni achitsulo, komanso chikasu chopepuka ndi lalanje mukakumana ndi ayoni a zinc ndi ammonium.

Direct Yellow R Application

1. Direct yellow Ramagwiritsidwa ntchito popaka thonje kapena nsalu za viscose zokhala ndi kuwala kofiira kwachikasu.Mulingo wake ndi kusamuka kwake ndizosauka.Popaka utoto, uyenera kuwonjezeredwa mchere kuti usamalowerere utoto kuti ukhale wofanana.Pambuyo popaka utoto, malo osambira opaka utoto amayenera kuzizidwa mwachilengedwe mpaka 60 ~ 80 ℃ kuti athandizire kuyamwa kwa utoto.Pambuyo popaka utoto, kufulumira kwa chithandizo chonyowa kumatha kupitsidwanso ndi kukonza chithandizo cha wothandizira.

2. Direct yellow Rangagwiritsidwenso ntchito podaya silika ndi ubweya.Akagwiritsidwa ntchito popaka nsalu zosakanikirana, mtundu wa silika ndi ubweya umakhala wopepuka kwambiri kuposa ulusi wa thonje ndi viscose, ulusi wa acrylic umakhala wodetsedwa pang'ono, ndipo nayiloni, ulusi wa diacetate ndi ulusi wa poliyesitala sizimadetsedwa.

3. Direct yellow Rnthawi zambiri sagwiritsidwa ntchito posindikiza nsalu za thonje ndi viscose, komanso kusindikiza kwamtundu wapansi.

4. Direct yellow Ramagwiritsidwa ntchito kwambiri popaka silika wa viscose ndi nsalu zopotoka.Kupaka utoto wa sopo kumatha kupanga silika kukhala woyera.
