ABSTRACT : A novel rNtric acid-free desmut solution has been dev이。p은d to remove smut, which is produced from a NaOH etching, on the surface of aluminum alloy metal in metal surface treatment processes. Contains Hazardous Goods. The smut removal effect was confirmed using an aqueous desmut solution composed of sulfuric, nitric, and hydrofluoric acids. 공정도
The desmut solution contains strong mineral acids, and when aluminum-silicon alloys are treated, fluoride ions. It could come in handy and does not hurt to use it on all aluminum alloys. Use to minimize smutting of aluminum parts before anodizing or plating. In this study, suitable desmut solutions for 3D printed AlSi7Mg and AlSi10Mg materials with high silicon contents were presented, and the chromate coating properties were studied accordingly. Meaning of Demut., preferably from about 90 to about 110° F. The adhesion of the nickel to the three aluminum samples in the 90° bend test is Good.
