Kodi glacial acetic acid ndi chiyani, makamaka pakugwiritsa ntchito m'munda,
mtengo wapakhomo wa asidi acetic, Kupaka utoto wa acetic acid mtengo lero, Kupaka Acetic Acid, kudaya acetic acid opanga zoweta, kudaya acetic acid kwenikweni, kupanga utoto wa acetic acid, dyeing acetic acid model, mtengo wa asidi acetic, Kupaka Acetic Acid Supplier, kugwiritsa ntchito acetic acid,
Kufotokozera za khalidwe

Physicochemical katundu:
1.Zamadzimadzi zopanda mtundu komanso dour wokwiyitsa.
2.Kusungunuka kwamadzi, ethanol, benzene ndi ethyl ether immiscible, osasungunuka mu carbon disulphide.
Posungira:
1.Isungeni pamalo ozizira, opanda mpweya wabwino
2.Kutalikirana ndi kutentha pamwamba, zipsera, malawi otseguka ndi zina zoyatsira, osasuta. M'nyengo yozizira, sungani pamwamba pa 0 ℃ kuti mupewe kuzizira.
3.Sungani chidebe chotsekedwa mwamphamvu.chiyenera kukhala chosiyana ndi oxidant ndi alkali.
4.Gwiritsani ntchito zida zosaphulika [magetsi / mpweya / zowunikira].
5.Gwiritsani ntchito zida zosayambitsa moto.
6.Ground ndi chomangira chidebe ndi kulandira equipmen
Kugwiritsa ntchito
1. M'malo mwa glacial acetic acid, amagwiritsidwa ntchito popaka utoto ndi kumaliza ma pro-cesses a acrylic. dacron, nayiloni ndi Chemical fiber, ubweya. silika ndi nyama zina ulusi, thonje. nsalu. ulusi ndi mbewu zina CHIKWANGWANI, Waxprinting, ndi kusakaniza nsalu.
2. Kusintha kwa PH mtengo wa mitundu yonse ya pickling asidi, dyeingbath (kuphatikizapo kusamba kwamtundu), kukonza mtundu, kutsirizitsa utomoni etc.
3. Kupanga mitundu ina ya utoto, monga Benzidine Yellow G.
Ubwino
Ntchito ndi zotsatira zake ndizabwino kuposa ma asidi ena opaka utoto ndi glacial acetic acid.lt ilibe kuwonongeka kwa ulusi, mu dyeing bath pHvalue ndi stable.ilibe pinda la asidi, zinyalala ndi zotsatira za madzi olimba, kupititsa patsogolo kutengera utoto komanso kuyika katundu. za zinthu zina zadyes, ndipo zilibe mphamvu pa kuwala kwachikuda kapena kufulumira kwa mtundu wa zinthu zopangidwa ndi utoto. Komanso, palibe fungo lamphamvu, losazizira m'nyengo yozizira, ndi lotetezeka komanso losavuta kugwiritsa ntchito.1. Kugwiritsa ntchito glacial acetic acid pakupanga viniga.

M'zaka zaposachedwa, ndi mpikisano wosalekeza wa msika wachuma, opanga apanga mndandanda wa edible glacial acetic acid kuti apulumutse zopangira ndikuchepetsa mtengo, kuti alowe m'malo mwa zopangira zazikulu za viniga balere ndi wowuma. Makamaka, kugwiritsa ntchito glacial acetic acid popanga viniga ndi motere:

(1) Kugwiritsa ntchito mwanzeru glacial acetic acid. Kugwiritsa ntchito moyenera glacial acetic acid popanga viniga wodyedwa kungathandize kuchepetsa mtengo wopangira viniga ndikukulitsa mpikisano wake wamsika.

(2) Kuchulukitsa kupanga hydrolysis ya glacial acetic acid. Glacial acetic acid imakhala ndi mphamvu yowira kwambiri komanso yosungunuka, kotero imatha kusungunuka mwachindunji mu viniga powonjezera madzi, ndipo imakhala ndi khalidwe lokhazikika ngati viniga.

(3) Samalani ubwino wa hydrolyzed glacial acetic acid. Ngakhale hydrolyzed glacial acetic acid akhoza kupulumutsa mtengo kupanga opanga, kuonjezera ubwino wake zachuma, koma m'kati mwa hydrolyzed acetic asidi kwa gawo la glacial acetic acid ayenera kulamulidwa mu osiyanasiyana zolimbitsa, apo ayi zingakhudze khalidwe la edible. vinyo wosasa, kuchepetsa kapangidwe kake ka zakudya, kuti abweretse zotayika ku chuma chabizinesi.

2. Kugwiritsa ntchito glacial acetic acid popanga bowa wodyedwa.

Monga mankhwala osungunulira, glacial acetic acid angagwiritsidwe ntchito osati popanga viniga wodyedwa, komanso popanga bowa wodyedwa. Ntchito zenizeni ziyenera kukhala ndi mfundo izi:

(1) Chithandizo cha zinthu chikhalidwe. M'zinthu zachikhalidwe za bowa zodyedwa, chifukwa cha nthawi yosungiramo, mabakiteriya ena osiyanasiyana adzaswana mu chikhalidwe cha chikhalidwe, ndipo zimakhala zovuta kuchotsa, motero zimakhudza ubwino wa bowa wodyedwa.

(2) Katemera wotsegula. Kulima bowa wodyedwa, nthawi zambiri kumachitika m'bokosi la katemera, koma chifukwa cha kukhudzidwa kwa zinthu zosiyanasiyana, kulima bowa wodyedwa mubokosi la katemera, kupulumuka kwa kulima kumakhala kochepa kwambiri. Kulima bowa wodyedwa ndi glacial acetic acid kumatha kupititsa patsogolo kulima kwake.

(3) Kupha tizilombo toyambitsa matenda m’mlengalenga. Glacial acetic acid, monga chosungunulira mankhwala, itha kugwiritsidwanso ntchito kupha tizilombo Malo. Polima bowa wodyedwa, nthawi zambiri pamakhala mabakiteriya oswana, omwe angayambitse kuipitsa kwakukulu komanso kovuta kuchotsa. Pochita izi, ngati 0.5% glacial acetic acid ikhoza kupopera ndikuwotchedwa fumigation, zimathandizira kuchepetsa mabakiteriya ndikuwonetsetsa kulima kwa bowa wodyedwa.
