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 zoziziritsa kukhosi komanso mpweya wabwino.
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 kuti mupewe / 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 asidi, acetinanisolic, acetinanisolic asidi , 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
7. Labala lachilengedwe: Coagulant
8. Makampani omangamanga: 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 utoto wobalalitsa umawonjezera glacial acetic acid kuti asinthe PH? (Ma Organic acid tsopano awonjezedwa kuti asinthe PH, kupatula madontho a alkaline disperse.)
Chifukwa chake ndi:
Kukhazikika kwa utoto wobalalitsa pakusamba kwa utoto kumagwirizana kwambiri ndi mtengo wa pH. Makamaka pa kutentha kwakukulu ndi kuthamanga kwambiri, 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 wa kumwazikana utoto, mu ndondomeko kupanga utoto, nthawi zambiri kuwonjezera chiwerengero chachikulu cha dispersant, monga diffuser NNO, lignin, sodium carbonate, kuti utoto njira ndi ofooka zamchere, mu
Mukadaya pa 130% kutentha kwambiri, ndikosavuta kuyika hydrolyze, zomwe zimapangitsa kuti pakhale utoto wopepuka komanso kuwala kocheperako.
(2) Chifukwa cha kuchepetsa kuwonongeka kwa utoto wobalalika, kutayika kwa gulu loyambira tsitsi, chodabwitsa ichi nthawi zambiri chimakhala mumtundu wa azo wa utoto.
(3) Gulu la phenolic mu kapangidwe ka maselo a utoto kumayambitsa ma ionic chifukwa cha zochita za alkali, komanso kusungunuka kwamadzi kumakulitsidwa, pomwe utoto wapamwamba umafooka chimodzimodzi. Nthawi zambiri, madzi omwaza a utoto amakhala ofooka amchere chifukwa cha kuwonjezera kwa dispersant mu bafa lopaka utoto.
