Izici ze-Physicochemical:
1. Uketshezi olungenambala kanye ne-dour ecasulayo.
2. Iphuzu elincibilikayo 16.6 ℃; indawo yokubilisa 117.9 ℃; Iphoyinti elikhanyayo : 39 ℃.
3. Amanzi ancibilikayo, i-ethanol, i-benzene ne-ethyl ether immiscible, engancibiliki ku-carbon disulphide.
Isitoreji:
1. Igcinwe endaweni epholile, nengena umoya.
2. Gcina kude nomlilo, shisa. Isikhathi esibandayo kufanele sigcine izinga lokushisa elingaphezu kuka-16 ° C, ukuvimbela ukuqina. Ngesikhathi esibandayo, izinga lokushisa kufanele ligcinwe lingaphezu kuka-16 DEG C ukuvimbela/ukugwema ukuqina.
3. Gcina isitsha sivaliwe. Kufanele ihlukaniswe ne-oxidant ne-alkali. Ukuxuba kufanele kugwenywe ngazo zonke izindlela.
4. Sebenzisa izibani ezingaqhumi, izindawo zokungena komoya.
5. Imishini kanye namathuluzi avimbela ukusetshenziswa kwezinhlansi okulula ukukhiqiza.
6. Izindawo zokugcina kufanele zifakwe izinto zokwelashwa eziphuthumayo kanye nempahla yezindlu ezifanele.
Sebenzisa:
I-1.Okuphuma kuyo:Isetshenziswa kakhulu ekuhlanganiseni i-acetic anhydride,i-acetic ether,i-PTA, i-VAC/PVA, i-CA, i-ethonone, i-chloroacetic acid, njll.
2.Ezemithi:I-acetic acid njengezinto ezincibilikisayo nezinto zokusetshenziswa kwemithi, ikakhulukazi esetshenziselwa ukukhiqizwa kwe-penicilin G potas-sium, i-penicilin G sodium, i-penicillin procaine, i-acetanilide, i-sulfadiazine, ne-sulfamethoxazole isoxazole, i-norfloxacin, i-ciprofloxacin, i-acetinalic acid, i-acetinalic acid, i-acetinalic acid , i-caffeine, njll.
3.Okumaphakathi:i-acetate,i-sodium hydrogen di,i-peracetic acid, njll
4. Ukuphrinta kwendwangu kanye nokudaya kwendwangu: Isetshenziswa kakhulu ukukhiqiza odayi abahlakazayo namadayi we-vat, nokuphrinta kwezindwangu kanye nokucubungula ukudaya
5. I-synthesis ammonia: Ngendlela ye-cuprammonia acetate, esetshenziswa ekucwengisiseni ama-syngas ukususa i-litl CO ne-CO2
6. Isithombe: Unjiniyela
7. Irabha yemvelo: I-Coagulant
8. Imboni yezokwakha: Ukuvimbela ukhonkolo ekushiseni9. I-Addtin ibuye isetshenziswe kabanzi ekwelapheni amanzi, i-syntheticfiber, izibulala-zinambuzane, amapulasitiki, isikhumba, upende, ukucubungula insimbi kanye nemboni yenjoloba.
Abantu abaningi abazi ukuthi yini ukuphrinta nokudaya, ukuphrinta nokudaya kubizwa nangokuthi ukudaya nokuqeda, kuwuhlobo lwendlela yokucubungula kwangaphambili kwendwangu, ikakhulukazi ekusebenziseni kwethu kwansuku zonke ukuphrinta kwendwangu. Enqubweni yokunyathelisa nokudaya, ngokuvamile sisebenzisa uviniga weqhwa. Ngakho-ke yini iviniga ye-iced? Uviniga obandayo owaziwa nangokuthi i-acetic acid, owaziwa nangokuthi i-acetic acid, i-organic monic acid, iyisakhi esiyinhloko sokusebenzisa uviniga nsuku zonke. Emazingeni okushisa asekamelweni, indawo yawo yokuqandisa ingu-16.6 ° C, futhi izoba yikristalu engenambala ngemva kokuqina.
Pho kungani sisebenzisa i-glacial acetic acid ekunyatheliseni nasekudayeni? Kungani ukuphrinta nokudaya kusebenzisa i-glacial acetic acid? Kungani ufaka i-glacial acetic acid ekuphrinteni nasekudayeni inqubo? Lokhu kungenxa yokuthi lapho sinyathelisa futhi sidaya, inani le-pH le-polyester yokuhlakaza udayi kufanele libe phakathi kuka-4-6, ngakho-ke lapho kulungiswa udayi, kuyadingeka ukusebenzisa i-glacial acetic acid ukuze ihlanjululwe, isibonelo, lapho sinyathelisa futhi sidaya. , amanzi adingekayo ukuze kudaye amathani angu-4, khona-ke sidinga ukwengeza amamililitha angu-1000 we-glacial acetic acid ukuze silungise inani le-pH libe ngu-4-6.
Lokhu kulungiswa kungasisiza ukuba sizinzise udayi ngezinga elikhulu futhi sigweme inkinga yokudida umbala lapho sinyathelisa. Kodwa-ke, eminyakeni yamuva nje, ukuthuthukiswa kwemboni yokunyathelisa nokudaya yaseShayina kuye kwaziswa kakhulu nguhulumeni kanye nemboni yendwangu, futhi umbuso ufake uguquko lobuchwepheshe embonini yokunyathelisa nokudaya kwenye yezimboni ezibalulekile ezisekelwa yindwangu. imboni, ngakho-ke izindlela zokudaya zemboni yokunyathelisa nokudaya ziye zathuthukiswa kakhulu, ngikholelwa ukuthi ngokuthuthukiswa okuqhubekayo kwentuthuko yesayensi, Kumele sikwazi ukusebenzisa izindlela zesayensi ukunqoba imboni yokunyathelisa nokudaya kanzima ukuxazulula inkinga ye-pH value. .
Kungaziwa ukuthi okwamanje, sisebenzise izindlela zesayensi ukuvela ubuchwepheshe besimanje be-elekthronikhi kanye nobuchwepheshe obuzenzakalelayo, i-biotechnology kanye neminye imboni yobuchwepheshe obuphezulu bokuphrinta nokudaya. Ubuchwepheshe bokuphrinta nokudaya obungenawo amanzi noma obungenawo amanzi obufana nokuphrinta kwe-micro-suspension, ukuphrinta kokudlulisa, nokuphrinta kwedijithali, okuvame kakhulu ekukhiqizeni, kuye kwasheshisa kakhulu ukusebenza kahle kocwaningo nokuthuthukiswa kanye nokukhiqizwa kwezindwangu zemvelo kanye nezindwangu ezisebenzayo. Ngokwezinga elikhulu kakhulu, ukuvimbela nokulawulwa kokungcola kwemboni yokunyathelisa nokudaya kuye kwafezeka, futhi ukuguqulwa kusukela ekuphathweni kokugcina kuya ekuvimbeleni umthombo kuye kwafinyelelwa.
Kodwa-ke, uma kuqhathaniswa nezindlela zasendulo zokunyathelisa nokudaya e-China, isayensi yesimanje nobuchwepheshe ukunyathelisa nokudaya ayinakho isimiso sokubeka indlela yasendulo, izinzuzo zokushesha kombala okuhle futhi akulula ukufiphala. Kodwa sikholelwa ukuthi ngokuthuthuka okusheshayo kwesayensi, ekugcineni sizozinqoba lobu bunzima futhi sithole izindlela ezingcono kakhulu zokunyathelisa nokudaya. Ukuhlanganisa ubuchwepheshe bokunyathelisa nokudaya bendabuko nobuchwepheshe besimanje bokunyathelisa nokudaya, ukuthatha ingqikithi nokuqeda ukungcola, ukuthola izindlela zobuchwepheshe ezithuthuke kakhulu nokuzuza imiphumela ephawulekayo yezimboni.
