127-09-3 |Sodium Acetate (Anhydrous)
Khoom Description
Sodium acetate yog anhydrous hmoov thiab agglomerate.Ob lub versions no yog chemically zoo tib yam thiab txawv tsuas yog nyob rau hauv lub cev daim ntawv.Lub agglomerate muaj cov khoom ntawm cov pob zeb uas tsis yog hmoov av, cov chaw wettability, siab dua bulk ntom ntom ntom ntom.
Sodium acetate anhydrous yog siv nyob rau hauv kev lag luam kws tshuaj, raws li ib tug tsis nyob rau hauv lub photographic kev lag luam thiab raws li ib tug ntxiv rau cov tsiaj pub kom cov mis nyuj muaj roj ntau lawm.Nws kuj tseem siv rau hauv kev tsim cov khoom siv dyeing, ua cov khoom siv hluav taws xob polymerization, ua cov khoom siv hluav taws xob, ua cov tshuaj tsw qab, thiab hauv kev tsim cov hydroxyl oxides, uas yog siv los ua cov extractants hauv hydrometallurgy.
