Beschreibung
Zusammenfassung:	Dust-trapping salt paste, prepd. from MgCl2 and/or CaCl2, contains as additive, (I) up to 5 (3)% ethoxylated aminoalcohol and/or an ethoxylated acid amide, pref. ethoxylated amino-lauryl alcohol and ethoxylated oleic acid amide, in addn. to an esp.ethoxylated, non-ionic wetting agent, to improve wetting of dust, and to 5% boric acid and/or a borate used as corrosion-inhibitor. The paste is used in mining. Addn. of (I) increases dust-trapping capacity, w.r.t. max. dust-uptake as well as to dust-trapping rate; and reduces cracking of paste caused by boric acid and/or borate. Pref. (I) consists of 60-80% aminolauryl alcohol ethoxylated esp. with 3 mol. ethylene oxide and of 20-40% oleic acid amide ethoxylated esp. with 5 mol. ethylene oxide.
