Abakhiqizi be-sodium acetate ukuthi bangakhetha kanjani, i-sodium acetate discoloration ingaqhubeka nokusebenzisa?,
I-Sodium Acetate, umenzi we-sodium acetate, imodeli ye-sodium acetate, umphakeli we-sodium acetate,
Izici ze-Physicochemical:
1. I-monoclinic engenambala kanye ne-transparent monoclinic crystal prismatic or white crystalline powder, iphunga elingenaphunga noma elincane likaviniga, elibaba kancane, isimo sezulu esilula emoyeni owomile noswakeme.
2. Amanzi ancibilikayo (46.5g/100mL, 20℃, pH ka-0.1mol/L isixazululo samanzi ngu-8.87), i-acetone, njll., ancibilika ku-ethanol, kodwa engancibiliki ku-ether.
3.Indawo encibilikayo (℃): 324
Storge
1. Gcina endaweni evalekile futhi eyomile.
2. Ipakishwe ngepulasitiki elayishiwe, isikhwama esilukiwe noma isikhwama sesibhamu njengejazi langaphandle. I-acetate ye-sodium i-deliquescent, ngakho-ke kufanele ivikelwe kumswakama ngesikhathi sokugcinwa nokuhamba. Kwenqatshelwe ngokuphelele ukuthintana negesi ebolayo, kuvimbele ukuchayeka elangeni nasemvuleni, nokuyihambisa ngekhava yemvula.
Sebenzisa
1. Ukunqunywa komthofu, i-zinc, i-aluminium, insimbi, i-cobalt, i-antimony, i-nickel ne-tin. I-stabilizer eyinkimbinkimbi. Isiza, i-buffer, i-desiccant, i-mordant ye-acetylation.
2. Isetshenziselwa ukunquma umthofu, i-zinc, i-aluminium, insimbi, i-cobalt, i-antimony, i-nickel, ne-tin. Isetshenziswa njenge-esterification ejenti ku-organic synthesis kanye nezici eziningi ezifana nezidakamizwa zezithombe, imithi, ukuphrinta nokudaya ama-modants, ama-buffers, ama-reagents amakhemikhali, izilondolozi zenyama, i-pigment, ukushuka, njll.
3. Isetshenziswa njenge-buffer, i-ejenti yesinongo, i-ejenti yokunambitheka kanye nesilawuli se-pH. Njengesigcinalwazi se-ejenti yokunambitheka, u-0.1% -0.3% ungasetshenziswa ukudambisa iphunga elibi futhi uvimbele ukuguquguquka kombala ukuze kuthuthukiswe ukunambitheka. Inomphumela othile wokulwa nesikhunta, njengokusebenzisa u-0.1% -0.3% emikhiqizweni ye-surimi nesinkwa. Ingasetshenziswa futhi njenge-ejenti emuncu ye-sauce yesinongo, i-sauerkraut, imayonnaise, ikhekhe lenhlanzi, isobho, isinkwa, ikhekhe elinamathelayo, njll. Kuhlanganiswe ne-methyl cellulose, i-phosphate, njll, esetshenziselwa ukuthuthukisa ukulondolozwa kwamasoseji, isinkwa, okunamathelayo. amakhekhe, njll.
4. Isetshenziswa njengesivimbeli esishisayo ekuphekeni kwerabha ye-chloroprene elawulwa yi-sulfur. Umthamo ngokuvamile uyingxenye ye-0.5 ngesisindo. Ingasetshenziswa futhi njenge-agent exhumanisa iglue yezilwane.
5. Lo mkhiqizo ungasetshenziswa ukwengeza i-alkaline electroplating tin, kodwa awunawo umthelela osobala enqubweni yokugcoba kanye ne-electroplating, futhi akuyona isithako esidingekayo. I-acetate ye-sodium ivame ukusetshenziswa njenge-buffer, njenge-acid zinc plating, i-alkaline tin plating kanye ne-electroless nickel plating.

Kulabo abajwayele i-acetate ye-sodium, i-sodium acetate, eyaziwa nangokuthi i-acetate ye-sodium, isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi ama-studio wezithombe, ukuchithwa kwekhishi, ukuthuthwa kwendle, ngisho nasemikhiqizweni yokudla.
Abakhiqizi abaningi bokudla bazokhipha i-sodium acetate ukuze benze ukudla kugcinwe kangcono. Ngakho-ke, kubizwa ngokuthi i-sodium dehydrogenate embonini yokudla. Kubaluleke kakhulu ekuthuthukisweni kwemboni yokudla.
I-sodium dehydroacetate ingesinye sezilondolozi ezaziwa kakhulu embonini. Inezinzuzo ezilandelayo embonini yokudla:
1. Ingavimbela isikhunta
2. Ayibhidliki ngesikhathi kulungiswa ukudla
3. Ngeke ihwamuke uma ihlangana namanzi
4. Ukuzinza uma kuqhathaniswa, lapho ukushisa kungaqinisekisa ukuthi akukuchithi ukudla.
Abakhiqizi abaningi bazozwa i-acetate ye-sodium ngemuva kokuthenga umbala we-acetate ye-sodium ayilungile impela, lokhu kungenxa yokuthi i-acetate ye-sodium incibilika kakhulu emanzini, lapho kuhlangana neminye imibala ehlukene yensimbi, i-acetate ye-sodium izoba neminye imibala, umbala ubukeka kancane. njenge-acetate ye-sodium, uma isetshenziselwa ukwenza umsebenzi onzima kakhulu, lesi simo sibonisa ukuthi kufanele siqaphele!
Ngaphezu kwalokho, i-sodium acetate esiyithenge efektri kufanele igcinwe kahle, ukuze kugwenywe ukuguquguquka.
Uma kukhulunywa ngokulondolozwa kwe-acetate ye-sodium, ngisancoma izindlela zokugcina ezifanele nezilungile:
1. I-acetate ye-sodium khumbula ukuthi ungawathinti amanzi, ngakho-ke kufanele sivalwe futhi some ngaphansi kwesimo sokulondolozwa.
I-2 kumele inake ekuthuthweni ukwenza izinyathelo zokufaka umswakama, i-acetate ye-sodium nayo yesaba kakhulu i-tide, kodwa futhi ayikwazi ukuchayeka elangeni nasemvuleni, ekuthuthweni ukuyinika izinyathelo ezinhle zokuzivikela, ukuze kuqinisekiswe ukuthi ubumsulwa be-sodium acetate.
3. Esikhathini sethu sokuthutha, kufanele sikhumbule ukuhlola isimo sokupakisha se-acetate ye-sodium ngesikhathi. Kuphela uma sihlola ngenkuthalo, singagwema yini ukuthinta isimo esizinzile se-acetate ye-sodium futhi sibangele ukulahlekelwa kithi ngenxa yesikhwama sokupakisha esiphukile nesingcolile.
Ekukhetheni kweumenzi we-sodium acetates, kufanele sipholishe amehlo ethu ukuze sithole abakhiqizi abanokwethenjelwa, ngibone abakhiqizi abaningi ukuthi babone isidingo samakhasimende se-acetate ye-sodium ngentengo, lolu hlobo lwabakhiqizi abakutusi ukuthi ukhethe.
Uma sikhetha abakhiqizi be-acetate ye-sodium, kufanele sikhumbule ukukhetha abakhiqizi abanekhwalithi yomkhiqizo omuhle, ikhwalithi enhle, idumela elihle kanye nentengo ngokuhambisana nalokho esikulindele. Ngokuvamile, lolu hlobo lwabakhiqizi luzoba olokukhiqiza nokuthengisa, futhi luvikeleke ngemva kokuthengisa, futhi ngeke luvumele amakhasimende alahlekelwe.
