A liquid phase slit interference synthesis device

Abstract

The invention relates to a liquid phase slit interference synthesis device and method mainly applied to the field of silver powder liquid phase synthesis micrometers and nanometers. By means of a slit, an electrode plate and other components, a reduction liquid phase material is subjected to vertical drawing interference control, the concentration gradient, formed on the same vertical face of a mixing area, of a solution is invariant with time, and the steady-state continuous synthesis process is formed. The horizontal flow velocity, the electric field vertical drawing force and the chemical reaction drive force jointly act on liquid ions, ion oscillation is achieved to carry out space multi-dimensional rotation, acting force generates an interaction function, and an even and orderly liquid phase microcosmic control synthesis process is achieved. By means of the device and method, the synthesis manners that the concentration of a stirring kettle is variant with time, stirring is uneven, silver powder of different particle size ratios cannot be obtained through synthesis, and a great microcosmic part only depends on a surface activating agent are solved, and the liquid phase high-stability continuous backmixing-free silver powder synthesis control device and method for high-end slurry are initiated.

Description

technical field [0001] The invention belongs to the technical field of liquid phase synthesis equipment, and in particular relates to a liquid phase slit interference synthesis equipment which is mainly used in the liquid phase synthesis of silver powder in the field of micron and nanometer. Background technique [0002] Foreign medium and high-end silver powder monopolizes the domestic market, domestic enterprises are unwilling to invest heavily in silver powder production, domestic technological breakthroughs are difficult to match with low-end equipment, and the degree of automation is low. More than 90% of enterprises use stirred tanks as the main synthesis equipment, surfactants as the main control method, supplemented by other parameter controls, and the control stays at the macro level. There are inner hexagonal stirred tanks, and the mixing degree is greatly improved. However, it is still unable to solve the synthesis process in which the concentration changes irregu...
