Physicochemical zog:
1.Colorless kua thiab irritating dour.
2.Solubility dej, ethanol, benzene thiab ethyl ether immiscible, insoluble nyob rau hauv carbon disulphide.
Cia:
1. Khaws rau hauv qhov chaw txias, qhov cua
2. Khaws kom deb ntawm tshav kub, nplaim taws, qhib nplaim taws thiab lwm yam khoom siv hluav taws xob, tsis txhob haus luam yeeb. Nyob rau lub caij ntuj no, khaws cia siab tshaj 0 ℃ kom tsis txhob khov.
3. Khaws lub thawv kaw kom nruj.yuav tsum tau muab cais tawm ntawm cov oxidant thiab alkali.
4.Siv tawg-pov thawj [hluav taws xob/ventilating/teeb pom kev] khoom.
5.Siv cov cuab yeej uas tsis muaj teeb meem.
6.Ground thiab daim ntawv cog lus thawv thiab txais cov khoom siv
Daim ntawv thov
1. Es tsis txhob glacial acetic acid, nws yog siv nyob rau hauv dyeing thiab finishing pro-cesses ntawm acrylic. dacron, nylon thiab lwm yam tshuaj fiber ntau, ntaub plaub. silk thiab lwm yam tsiaj fiber, paj rwb. linen. xov paj thiab lwm yam nroj tsuag fiber ntau, Waxprinting, thiab muab ntaub.
2. Kev hloov kho ntawm PH tus nqi ntawm txhua yam acid pickling, dyeingbath (xws li da dej xim), xim kho, resin xov thiab lwm yam.
3. Ua tau qee yam dyestuff, xws li Benzidine Yellow G.
Qhov zoo
Kev ua haujlwm thiab cov nyhuv zoo dua li lwm cov dyeing acid andglacial acetic acid.lt tsis muaj kev puas tsuaj rau cov fiber ntau, hauv dyeing da dej pHvalue yog ruaj khov.it tsis muaj kua qaub quav, sediment thiab cov teebmeem ntawm cov dej tawv, txhim kho cov xim zoo nkauj thiab qib-dyeing khoom. ntawm somedyestuff, thiab tsis muaj qhov cuam tshuam rau lub teeb xim lossis xim ceev ntawm cov khoom lag luam. Ntxiv rau, tsis muaj ntxhiab tsw ntxhiab, tsis khov rau lub caij ntuj no, nyab xeeb thiab siv tau yooj yim.
