Sodium Acetate Anhydrous
Physicochemical properties:
1. Isina ruvara uye yakajeka monoclinic prismatic crystal kana white crystalline poda, isina kunhuhwirira kana zvishoma vhiniga kunhuhwirira, zvishoma kuvava, nyore kutonhora mumhepo yakaoma uye ine unyoro.
2. Solubility mvura (46.5g/100mL, 20℃, PH ye0.1mol/L aqueous solution is 8.87), acetone, etc., soluble in ethanol, but insoluble in ether.
3.Kunyungudika (℃): 324
Storge
1. Chengetedza munzvimbo yakavharwa uye yakaoma.
2. Yakarongedzwa nepurasitiki bhegi rakarukwa, rakarukwa kana bhegi repfuti sejachi rekunze. Sodium acetate inonyangadza, saka inofanira kuchengetedzwa kubva kune unyoro panguva yekuchengetedza uye kutakura. Zvinorambidzwa zvachose kubata gasi rinoparadza, kudzivirira kutarisana nezuva nemvura, uye kutakura nemvura inovhara.
Shandisa
1. Kutsunga kwemutobvu, zingi, aluminium, iron, cobalt, antimony, nickel uye tini. Complexing stabilizer. Mubatsiri, buffer, desiccant, mordant yeacetylation.
2. Inoshandiswa kuona lead, zingi, aluminium, iron, cobalt, antimony, nickel, uye tin. Inoshandiswa senge esterification mumiriri mune organic synthesis uye akawanda maficha akadai semishonga yemifananidzo, mishonga, kudhinda uye dhayi modants, buffers, kemikari reagents, zvinochengetedza nyama, pigment, tanning, nezvimwe.
3. Inoshandiswa sebuffer, flavoring agent, flavoring agent uye pH regulator. Semushonga wekunhuhwirira, 0.1% -0.3% inogona kushandiswa kuderedza kunhuhwirira kwakashata uye kudzivirira kushanduka kwemavara kuvandudza kunaka. Iyo ine imwe anti-mold maitiro, sekushandisa 0.1% -0.3% mune surimi zvigadzirwa uye chingwa. Inogona zvakare kushandiswa seyakavava mumiriri wekurungwa muto, sauerkraut, mayonnaise, hove keke, soseji, chingwa, inonamira keke, etc. Yakasanganiswa nemethyl cellulose, phosphate, nezvimwewo, inoshandiswa kuvandudza kuchengetedza kwemasoseji, chingwa, chinonamira. makeke, nezvimwewo.
4. Inoshandiswa se scorch inhibitor ye sulfur-regulated chloroprene rubber coking. Chiyero chinowanzoita 0.5 zvikamu nehuremu. Inogona zvakare kushandiswa seyakachinjika mumiririri wemhuka glue.
5. Ichi chigadzirwa chinogona kushandiswa kuwedzera alkaline electroplating tin, asi haina mhedzisiro yakajeka pakuputira uye electroplating process, uye haisi chinhu chakakosha. Sodium acetate inowanzo shandiswa sebuffer, senge acid zinc plating, alkaline tin plating uye electroless nickel plating.
