experiment example

[0136] Next, an experiment was conducted on the relationship between the viscosity and the Zeta potential when the charge was adjusted by the above-mentioned charge adjustment method. The experimental method is that the aluminum oxide (α-Al 2 o 3 ) particles (diameter 100nm) liquid, while gradually adding polystyrene sulfonic acid (PSS) solution, the viscosity and Jieda potential were measured. Then, the viscosity and the Zeta potential were measured when a poly(diallylmethylammonium chloride) (PDDA) solution was gradually added to the liquid containing the polyanion-adsorbing particles produced as above.

[0137] Figure 14 represent the experimental results. As shown in the graph of the figure, when the polyanion (PSS) is gradually added to the particles, the Zeta potential changes from positive to negative, and the time when the value first becomes a value near the minimum value is closely related to the viscosity of the liquid containing the particles. Small values ​​a...

Abstract

A device for producing composite particles and a process for producing composite particles are provided in which a modifier for modifying the surface charge of particles, such as a polymer electrolyte, can be added in a proper amount and operation efficiency and production efficiency can be thereby improved. The device is equipped with: a reservoir tank (1) for holding therein a liquid that contains first particles or second particles; a dispersed-state determination means (2) that determines the dispersed state of the particles contained in the liquid held in the reservoir tank; a dispersed-state memory means (33) which, after a modifier that modifies the surface charge of the particles contained in the liquid present in the reservoir tank is introduced into the reservoir tank, memorizes the dispersed state determined by the dispersed-state determination means; and an information output means (37) which, on the basis of the dispersed state memorized by the dispersed-state memory means, outputs information showing that the dispersed state of the particles contained in the liquid present in the reservoir tank is a desired state.

Description

technical field [0001] The present invention relates to a manufacturing device and a manufacturing method for manufacturing composite particles, and more particularly to a manufacturing device and manufacturing of composite particles capable of easily and efficiently manufacturing composite particles by adding an appropriate amount of a regulator for adjusting the surface charge of the particles method. Background technique [0002] In general, in the production of composite particles, a mechanical mixing method of mixing two or more raw material particles using a ball mill or the like is known. However, in mechanical mixing such as a ball mill, it is difficult to avoid raw material contamination, or to increase the yield of target composite particles. Therefore, the following technology is disclosed: one kind of particle to be composited and another kind of particle are dispersed in the liquid phase whose pH is adjusted in such a manner that the surface charges are reverse...
