METHOD FOR SEARCHING OPTIMUM DISPERSION CONDITION AND PHYSICAL COHESION CONDITION OF WATER-BASE TITANUM-DIOXIDE SUSPENSIONS, METHOD FOR MANUFACTURING WATER-BASE TITANUM-DIOXIDE SOL BY USING THAT
The present invention is an aqueous dispersion of titanium dioxide best physical condition of the suspension and the optimum flocculation conditions and how to navigate its way Using that relates to a process for the manufacture of environmentally friendly aqueous titanium dioxide sol, the present invention provides a method for producing the environmentally friendly aqueous titanium dioxide sol using a zeta potential search through the search method described above; The first step to make the aqueous largest area is the repulsive force between the particles in the suspension of titanium dioxide through a pH control without using a dispersing agent using the measured zeta potential; The second step in creating a pulverized dispersed optimized dispersion of the particles in the region of the first stage; The third step in the repulsive force between the particles through the region with the lowest pH-adjusted without using an organic binder by the zeta potential measured for the aqueous suspension of titanium dioxide dispersed in a dispersion state in which optimal coagulation is physically through the second stage; Optimum dispersion conditions and optimal physical condition of aqueous titanium dioxide suspensions to agglomerate being configured including; a fourth step of concentration to impart thixotropy to the aqueous titanium dioxide suspension was subjected to coagulation sedimentation due to the third step provides a method of producing environment-friendly water-based search method using a titanium dioxide sol. According to the present invention, a separate organic solvent or without addition of an organic binder, without environment friendly and inexpensive and can be produced with excellent thixotropic and linkable aqueous titanium dioxide sol, titanium dioxide particles, when using a water-based sol according to the invention may be coated with a film by a force acting on the particles with each other. ; 展开▼
