| titleOfInvention | Method and device for preparing nano metal sulfide powder by using continuous flow foaming method |
| abstract | The invention discloses a method and device for preparing nano metal sulfide powder by using a continuous flow foaming method. A metal sulfide has a general formula of MS, wherein M is selected from divalent ions of Cd, Cu, Mn, Pb or Zn. The method comprises the following steps of: preparing a foaming agent-foam stabilizing agent solution, wherein the concentration of a foaming agent is 0.1-5wt percent, the weight ratio of the foaming agent to a foam stabilizing agent is (6-200):1; dividing the foaming agent-foam stabilizing agent solution into two parts, namely a solution A and a solution B; adding a soluble salt of M into the solution A to ensure that the molar concentration is 0.001-0.5mol/L, stirring to obtain a homogeneous phase solution C; adding a soluble sulfide into the solution B, stirring to obtain a homogeneous phase solution D, wherein the mole number of S<2-> in the solution D is equal to that of M <2+> in the solution C; and introducing gas to ensure that the solution C and the solution D are completely foamed, then mixing, reacting for 2-24h at a constant temperature of 50-100 DEG C, and post-treating to obtain the nano metal sulfide powder. The nano metal sulfide powder prepared by adopting the method is good in dispersibility and uniform in size within a range of 8-50nm, is homogeneous phase without impurities, can be massively prepared and is suitable for industrial production; and the process flow is simple. |
