Khoom specification

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 kev cuam tshuam rau cov xim xim los yog xim ceev ntawm cov khoom lag luam. Tsis tas li ntawd, tsis muaj ntxhiab tsw ntxhiab, tsis khov rau lub caij ntuj no, muaj kev nyab xeeb thiab siv tau yooj yim.Glacial acetic acid, uas yog anhydrous acetic acid. Nws yog ib tug carboxylic acid, belongs rau cov tsis muaj zog acid chav kawm ntawv, yog kev cob cog rua los ntawm ib pawg hydrocarbon thiab ib pab pawg neeg carboxylic, nws molecular qhia yog C2H4O2. Txawm li cas los xij, vim muaj cov ntsiab lus acetic acid siab hauv glacial acetic acid, feem ntau ntau dua 95%, nws cov kua qaub tsis hloov pauv rau qhov tseem ceeb, yog li nws qhia tau hais tias muaj zog volatility. Glacial acetic acid yog ib qho tseem ceeb chemical raw khoom, dav siv nyob rau hauv cov tshuaj, organic tshuaj kev lag luam, organic synthesis, hluavtaws fiber, polymer tshuaj lom neeg kev lag luam, tshuaj tua kab, tawv, roj hmab thiab lwm yam lag luam. Glacial acetic acid yog ib qho tseem ceeb ntawm cov organic acids. Nws yog tsuas yog siv nyob rau hauv lub synthesis ntawm monochloroacetic acid, vinyl acetate, amino acid thiab hais txog. Glacial acetic acid ua cov khoom siv tshuaj zoo. Hauv kev lag luam tshuaj, kev lag luam khoom noj thiab lwm yam lag luam kuj muaj kev lag luam dav. Glacial acetic acid ua cov tshuaj reagent yog ib qho ntawm ntau hom.
