Ntchito ya glacial acetic acid podaya

Udindo wa glacial acetic acid mu utoto,
Glacial Acetic Acid, glacial acetic acid zochita ndi ntchito, glacial acetic acid China, Opanga glacial acetic acid, Glacial Acetic Acid Suppliers,
Makhalidwe abwino (GB/T 1628-2008)

Physicochemical katundu:
1. Zamadzimadzi zopanda mtundu komanso zowawa.
2. Malo osungunuka 16.6 ℃;kutentha kwa 117.9 ℃;Kuwala kwapakati: 39 ℃.
3. Madzi osungunuka, ethanol, benzene ndi ethyl ether immiscible, osasungunuka mu carbon disulphide.

Posungira:
1. Zosungidwa m'nyumba yosungiramo zinthu zozizirirapo mpweya wokwanira.
2. Khalani kutali ndi moto, kutentha.Nyengo yozizira iyenera kukhalabe kutentha kuposa 16 ° C, kupewa kulimba.M'nyengo yozizira, kutentha kuyenera kusungidwa pamwamba pa 16 DEG C kuteteza / kupewa kulimba.
3. Sungani chidebe chosindikizidwa.Ayenera kupatulidwa ndi okosijeni ndi zamchere.Kusakaniza kuyenera kupewedwa mwa njira zonse.
4. Gwiritsani ntchito kuyatsa kosaphulika, malo olowera mpweya.
5. Zipangizo zamakina ndi zida zomwe zimaletsa kugwiritsa ntchito zosavuta kupanga zopsereza.
6. Malo osungiramo zinthu ayenera kukhala ndi zipangizo zothandizira chithandizo chadzidzidzi komanso zipangizo zoyenera zapanyumba.

Gwiritsani ntchito:

1.Drivative: Amagwiritsidwa ntchito popanga acetic anhydride, acetic etha, PTA, VAC/PVA, CA, ethenone, chloroacetic acid, etc.
2.Pharmaceutical:Acetic acid monga zosungunulira ndi mankhwala zopangira mankhwala, makamaka ntchito kupanga penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, ndi sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetinanisolic, acetinanisolic acid, prefloxacin, acetinasolic acid, acetinal, acetinal, sulfadiazine. , caffeine, etc.
3. Yapakatikati: acetate, sodium hydrogen di, peracetic acid, etc
4.Dyestuff ndi nsalu yosindikiza ndi utoto: Amagwiritsidwa ntchito kwambiri popanga utoto wobalalitsa ndi utoto wa vat, ndi kusindikiza kwa nsalu ndi kukonza utoto
5. Kaphatikizidwe ammonia: Mu mawonekedwe a cuprammonia acetate, ntchito kuyenga syngas kuchotsa litl CO ndi CO2
6. Chithunzi: Wopanga mapulogalamu
7. Labala lachilengedwe: Coagulant
8. Makampani omanga: Kupewa konkire ku frezing9.Mu addtin amagwiritsidwanso ntchito kwambiri pochiza madzi, syntheticfiber, mankhwala ophera tizilombo, mapulasitiki, zikopa, utoto, kukonza zitsulo ndimakampani amphira.

Utoto wobalalitsa umagwiritsidwa ntchito tsiku lililonse, koma mutha kunena nthawi yomweyo, chifukwa chiyani mumamwaza utoto ndi glacial acetic acid kuti musinthe PH?(Ma Organic acid tsopano awonjezedwa kuti asinthe PH, kupatula utoto wa alkaline disperse dyeing)

Chifukwa chake ndi:

Kukhazikika kwa utoto wobalalitsa pakusamba kopaka utoto kumagwirizana kwambiri ndi mtengo wa pH.Makamaka pa kutentha kwakukulu ndi kuthamanga kwakukulu, ngati pH mtengo wa kusamba kwa utoto sunayendetsedwe bwino, nthawi zambiri zimayambitsa kusiyana kwa kuwala kwa mtundu, zifukwa zazikuluzikulu ndi izi.

(1) Chifukwa inapita patsogolo hydrolysis a kumwazikana utoto, mu kupanga ndondomeko utoto, nthawi zambiri kuwonjezera chiwerengero chachikulu cha dispersants monga kufalitsa wothandizira NNO, lignin, sodium carbonate, etc., kuti utoto ndi ofooka zamchere, mu
Mukadaya pa 130% kutentha kwambiri, ndikosavuta kuyika hydrolyze, zomwe zimapangitsa kuti pakhale utoto wopepuka komanso wofooka.
(2) Chifukwa cha kuchepetsa kuwonongeka kwa utoto wobalalika, kutayika kwa gulu la chromophore, chodabwitsa ichi nthawi zambiri chimakhala mu utoto wokhala ndi kapangidwe ka azo.
(3) Gulu la phenolic mu kapangidwe kake ka utoto kamapangitsa kuti ionic ichitike chifukwa cha zochita za alkali, kusungunuka kwamadzi kumakulitsidwa, ndipo utoto umakhala wofooka moyenerera, nthawi zambiri chifukwa cha kuwonjezera kwa dispersant mu bafa lopaka utoto. , zomwe zimapangitsa kuti utoto ukhale wochepa mphamvu wa alkaline.
