Sodium Acetate Anhydrous
Imiterere yumubiri:
1. Ibara rya monoclinic prismatic kristal cyangwa ifu ya kristaline yera, impumuro nziza cyangwa vinegere nkeya, impumuro nziza, byoroshye ikirere mubihe byoroshye kandi bitose.
2. Amazi ya elegitoronike (46.5g / 100mL, 20 ℃, PH ya 0.1mol / L yumuti wamazi ni 8.87), acetone, nibindi, gushonga muri Ethanol, ariko ntibishonga muri ether.
3.Gushonga ingingo (℃): 324
Ububiko
1. Bika ahantu hafunze kandi humye.
2. Gipfunyikishije umufuka wa pulasitike utondekanye, umufuka uboshye cyangwa igikapu cyimbunda nkikoti ryo hanze. Sodium acetate ni deliquescent, igomba rero kurindwa nubushuhe mugihe cyo kubika no gutwara. Birabujijwe rwose guhura na gaze yangirika, kwirinda izuba n'imvura, no kubitwara bitwikiriye imvura.
Koresha
1. Kumenya isasu, zinc, aluminium, icyuma, cobalt, antimoni, nikel na tin. Igikoresho gikomeye. Umufasha, buffer, desiccant, mordant ya acetylation.
2. Byakoreshejwe mukumenya isasu, zinc, aluminium, icyuma, cobalt, antimoni, nikel, na tin. Ikoreshwa nka esterification agent muri synthesis organique nibintu byinshi nkimiti ifotora, imiti, icapiro nogusiga amarangi, buffers, imiti yimiti, imiti yinyama, pigment, tanning, nibindi.
3. Ikoreshwa nka buffer, uburyohe, uburyohe hamwe na pH igenzura. Nka buffer ya flavouring agent, 0.1% -0.3% irashobora gukoreshwa kugirango igabanye impumuro mbi kandi irinde ibara kugirango ihindure uburyohe. Ifite ingaruka zimwe zo kurwanya ibicuruzwa, nko gukoresha 0.1% -0.3% mubicuruzwa bya surimi numugati. Irashobora kandi gukoreshwa nkibikoresho bikarishye bya sosi, sauerkraut, mayoneze, cake y amafi, sosiso, umutsima, cake ifata, nibindi bivanze na methyl selulose, fosifate, nibindi, bikoreshwa mugutezimbere kubungabunga isosi, umutsima, bifatanye udutsima, n'ibindi.
4. Ikoreshwa nka inhibitor ya scorch ya sulfure igenzurwa na chloroprene reberi. Igipimo muri rusange ni ibice 0.5 kubwinshi. Irashobora kandi gukoreshwa nkigikoresho cyo guhuza kashe yinyamaswa.
5. Iki gicuruzwa gishobora gukoreshwa mu kongeramo amabati ya alkaline, ariko nta ngaruka zigaragara zigira ku gutwikira no gukwirakwiza amashanyarazi, kandi ntabwo ari ikintu gikenewe. Sodium acetate ikoreshwa kenshi nka buffer, nka acide zinc plaque, amabati ya alkaline hamwe na nikel idafite amashanyarazi.
