Sodium Acetate Anhydrous
Astaamaha physicochemical:
1. Midab la'aan iyo hufnaan monoclinic prismatic crystal ama budo crystalline cad, ur khal aan ur lahayn ama wax yar, waxyar qadhaadh, si sahlan cimilada qalalan iyo hawo qoyan.
2. Biyaha milmida (46.5g/100mL, 20℃, PH of 0.1mol/L aqueous solution is 8.87), acetone, iwm
3.Meelting point (℃): 324
Kaydka
1. Ku kaydi meel xidhan oo qallalan.
2. Ka buuxa bac safan, bac tolan ama bac qoryo ah sida jaakad dibadda ah. Sodium acetate waa deliquescent, sidaas darteed waa in laga ilaaliyo qoyaanka inta lagu jiro kaydinta iyo gaadiidka. Waxaa si adag loo mamnuucay in lala xiriiro gaaska daxalka, ka hortagga soo-gaadhista qorraxda iyo roobka, iyo in lagu qaado daboolka roobka.
Isticmaal
1. Go'aaminta rasaasta, zinc, aluminium, iron, cobalt, antimony, nikkel iyo tiin. Xasijiye kakan. Kaaliyaha, kaydinta, qalajiyaha, mordant for acetylation.
2. Waxaa loo isticmaalaa in lagu go'aamiyo rasaasta, zinc, aluminium, iron, cobalt, antimony, nikkel, iyo tiin. Loo isticmaalo sidii wakiilka esterification ee isku-dhafka dabiiciga ah iyo dhinacyo badan sida dawooyinka sawir-qaadista, daawooyinka, daabacaadda iyo midabaynta mordants, bakhaarrada, reagents kiimikaad, ilaalinta hilibka, midabada, hargaha, iwm.
3. Waxaa loo istcimaalaa sidii kaydiye, wakiilka dhadhamin, wakiilka dhadhanka iyo xakamaynta pH. Sida kaydka wakiilka dhadhanka, 0.1%-0.3% waxaa loo isticmaali karaa in lagu yareeyo ur xun loogana hortago midab-doorsoomidda si loo hagaajiyo dhadhanka. Waxay leedahay saameyn liddi ku ah caaryada qaarkood, sida isticmaalka 0.1%-0.3% ee alaabta surimi iyo rootiga. Waxa kale oo loo isticmaali karaa sida wakiilka dhanaan ee suugo xawaash, sauerkraut, majones, keega kalluunka, bolse, rooti, keega dhegdheg, iwm qaso cellulose methyl, fosfat, iwm, loo isticmaalo si loo hagaajiyo ilaalinta ee sausages, rootiga, dhegdheg. keega, iwm.
4. Waxa loo istcimaalaa sidii dab-bakhtiiye loogu talagalay coking chloroprene ee baaruudku nidaamsan yahay. Qiyaasta guud ahaan waa 0.5 qaybood oo cufan. Waxa kale oo loo isticmaali karaa sidii wakiilka iskutallaabta ee xabagta xayawaanka.
5. Alaabtan waxaa loo isticmaali karaa in lagu daro daasadaha elektiroonigga ah ee alkaline, laakiin ma laha saameyn muuqata oo ku saabsan habka korantada iyo korantada, mana aha walxo lagama maarmaan ah. Sodium acetate waxaa inta badan loo isticmaalaa kayd ahaan, sida aashitada zinc plating, daasadda daasadda alkaline-ka iyo darista nikkel-la'aanta.
