I-Sodium Acetate Anhydrous
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.
