Sodium Acetate Anhydrous
Physicochemical katundu:
1. Monoclinic prismatic kristalo wopanda mtundu kapena wowoneka bwino, wopanda fungo kapena fungo la vinyo wosasa pang'ono, wowawa pang'ono, wosavuta kuzizira mumpweya wouma komanso wachinyontho.
2. Madzi osungunuka (46.5g / 100mL, 20 ℃, PH ya 0.1mol / L yankho lamadzimadzi ndi 8.87), acetone, etc., sungunuka mu ethanol, koma osasungunuka mu etha.
3.Posungunuka (℃): 324
Storge
1. Sungani pamalo osindikizidwa ndi owuma.
2. Amapakidwa ndi thumba la pulasitiki lokhala ndi mizere, thumba loluka kapena thumba lamfuti ngati malaya akunja. Sodium acetate ndi yonyowa, choncho iyenera kutetezedwa ku chinyezi panthawi yosungira komanso yoyendetsa. Sizoletsedwa kukhudzana ndi mpweya wowononga, kuteteza ku dzuwa ndi mvula, ndikuyendetsa ndi mvula.
Gwiritsani ntchito
1. Kutsimikiza kwa lead, zinki, aluminiyamu, chitsulo, cobalt, antimoni, faifi tambala ndi malata. Complexing stabilizer. Wothandizira, buffer, desiccant, mordant wa acetylation.
2. Amagwiritsidwa ntchito pozindikira lead, zinki, aluminiyamu, chitsulo, cobalt, antimoni, faifi tambala, ndi malata. Amagwiritsidwa ntchito ngati esterification wothandizila mu kaphatikizidwe organic ndi mbali zambiri monga zithunzi mankhwala, mankhwala, kusindikiza ndi utoto mordants, buffers, mankhwala reagents, zosungira nyama, inki, pofufuta, etc.
3. Amagwiritsidwa ntchito ngati chotchinga, chokometsera, chokometsera ndi pH regulator. Monga chosungira cha zokometsera, 0.1% -0.3% itha kugwiritsidwa ntchito kuti muchepetse fungo loyipa ndikuletsa kusinthika kuti fungo likhale labwino. Ili ndi mphamvu yotsutsa nkhungu, monga kugwiritsa ntchito 0.1% -0.3% muzogulitsa za surimi ndi mkate. Itha kugwiritsidwanso ntchito ngati wowawasa wothandizira zokometsera msuzi, sauerkraut, mayonesi, keke nsomba, soseji, mkate, yomata keke, etc. Wosakaniza methyl mapadi, mankwala, etc., ntchito bwino kusunga soseji, mkate, zomata. makeke, etc.
4. Amagwiritsidwa ntchito ngati choletsa chowumitsa pophika mphira wa sulfure woyendetsedwa ndi chloroprene. Mlingo wake nthawi zambiri umakhala magawo 0.5 ndi misa. Itha kugwiritsidwanso ntchito ngati cholumikizira pagulu la nyama.
5. Mankhwalawa angagwiritsidwe ntchito kuonjezera malata a alkaline electroplating, koma alibe zotsatira zoonekeratu pa zokutira ndi electroplating ndondomeko, ndipo sizinthu zofunikira. Sodium acetate nthawi zambiri imagwiritsidwa ntchito ngati chotchingira, monga plating ya zinc acid, plating ya alkaline plating ndi electroless nickel plating.
