Claims20
A method to prevent dusting of fine materials, said method comprising the steps of
- providing a mist of an aqueous solution of organic ammonium carboxylate of formula (I):
- [NR1R2R3R4]+n [R5(COO)]−n, (I),
- in which R1, R2, and R3 are selected from the group composing of hydrogen and methyl, R4 is a C1-C4-alkyl substituted with a hydroxyl group, R5 is hydrogen or methyl and n is 1,
- applying the mist on the fine material, wherein the fine material is selected from the group composing of sand, crushed stone, minerals and metal powder.
