。Approximately 60 to 80 volumes of dispersion media 7 are loaded in the kneading and dispersion chamber 5, and abrasion stress is generated in the dispersion media 7 by rotating a stirring member such as a disk plate 80 times, which is attached to the rotating rod 3. , thereby kneading and dispersing the millpaste. It can be determined as appropriate depending on the type of the dispersion media Tu mill base, the degree of uniform dispersion, etc., but in the case of ordinary paints, it is glass, porcelain, alumina, or steel with a particle size of 1 to 5 mm.

る場合。In the apparatus shown in Fig. 1, only one training dispersion chamber 5 is provided, but if high-level kneading and dispersion is required, the kneading dispersion chamber 5 can be provided as shown in Fig. 2. It is divided into a plurality of chambers (three chambers in the drawing) by partition walls 4', 4'', etc. similar to the partition wall 4, and the dispersion media 7 of each chamber is 1111N in the direction of movement of the mill base. It is preferable to use media with a smaller diameter.Furthermore, if a dispersion media with a smaller diameter and a smaller specific gravity is used, a higher degree of kneading and dispersion can be obtained.In other words, when kneading and dispersing a mill base.

出来るようにすることが望ましい。Initially, the mill base contains secondary agglomerated coarse particles, and since a large amount of energy is required to disperse them to a certain extent, it is appropriate that the dispersion medium 7 has a large particle size and specific gravity. In addition, in order to further disperse the mill base kneaded and dispersed in this way to a high degree near the -order particles, it is necessary to increase the number of collisions so that the energy can be propagated evenly, rather than using large amounts of energy. The suitable rounding dispersion medium has a low specific gravity and a small particle size of 9°. Therefore, it is desirable to gradually reduce the particle size of the dispersion media in the direction of movement of the mill base, and more preferably to reduce the specific gravity, so that high-level kneading and dispersion can be achieved.

分間となる程度のものが適当である。The mill base is press-fitted into the kneading and dispersion chamber 5 from the supply port 10. The amount of mill base introduced depends on the rotational speed of the stirring member 8 such as a disc grate or stirring rod, the volume of the kneading and dispersing chamber 5,
This can be determined as appropriate depending on the type of dispersion media, the type of mill base, the degree of kneading and dispersion required by the mill base, etc.1 Usually, the residence time in the kneading and dispersing chamber 5 is about 2 to 20 minutes.
A length of about 1 minute is appropriate.
