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 lossis 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.Acetic acid (tseem hu ua acetic acid lossis glacial acetic acid) ₃ yog cov organic monic. acid vim lub acidity thiab pungent tsw nyob rau hauv vinegar. Ntshiab anhydrous acetic acid (glacial acetic acid) yog cov kua tsis muaj xim hygroscopic nrog qhov chaw khov ntawm 16.7 ° C (62 ° F). Thaum solidification, nws dhau los ua cov xim tsis muaj xim. Txawm hais tias acetic acid yog cov kua qaub tsis muaj zog raws li nws lub peev xwm los cuam tshuam rau hauv cov tshuaj aqueous, acetic acid yog corrosive thiab nws cov vapors ua rau khaus qhov muag thiab qhov ntswg.

Compatibility: Khoom siv: tom qab dilution muaj zog corrosion rau hlau, 316 # thiab 318 # stainless hlau thiab txhuas tuaj yeem yog cov khoom siv zoo.

Cov Khoom Siv Hauv Tebchaws: GB / T 676-2007

Acetic acid nyob rau hauv chav tsev kub yog cov kua tsis muaj xim uas muaj zog pungent acid saj. Lub melting point ntawm acetic acid yog 16.6 ℃ (289.6 K). Kub taw tes 117.9 ℃ (391.2 K). Tus txheeb ze ntom ntom yog 1.05, lub teeb nyem yog 39 ℃, thiab qhov tawg txwv yog 4% ~ 17% (ntim). Ntshiab acetic acid yuav khov rau hauv cov dej khov nab kuab hauv qab lub melting point, yog li anhydrous acetic acid kuj hu ua glacial acetic acid. Acetic acid yog soluble nyob rau hauv dej thiab ethanol, thiab nws cov kua aqueous yog weakly acidic. Acetate kuj yooj yim soluble hauv dej, thiab cov kua dej aqueous yog qhov yooj yim.
