1、 General State:
toosodium sulphateMolecular formulaNatwoStwoOeight，molecular weighttwo3eight.1eight。為白色單斜(xie)結晶(jing)或粉末，比重two.357，易(yi)溶(rong)(rong)于(yu)水(shui)，加熱至較high溫度時分(fen)解(jie)，放出氧而(er)變成(cheng)焦sodium sulphate。toosodium sulphate在low溫干燥的條件下具有極好的貯(zhu)存穩定(ding)性(xing)，遇潮(chao)濕和(he)催(cui)化劑則(ze)容易(yi)分(fen)解(jie)。toosodium sulphate溶(rong)(rong)液屬于(yu)優等品toosodium sulphate溶(rong)(rong)解(jie)于(yu)high純度去(qu)離子水(shui)而(er)成(cheng)，可直(zhi)接應用于(yu)電(dian)路板生產too程的各種(zhong)微蝕工藝，方便use。
This product is a strong oxidant. Avoid direct contact with eyes, skin and clothing.
