Looking for powder dispersant products for ceramics!

As the name suggests, the dispersant is to reasonably disperse various powders in the solvent, and make various solids very stably suspended in the solvent (or dispersion) through a certain charge repulsion principle or polymer steric hindrance effect. In the process of coating production, pigment dispersion is a very important production link, which is directly related to the storage of coatings.

Ceramic powder is commonly used alumina, zirconia, boron nitride, but the surface properties and preparation process of each powder are different, even if zirconia powder, different manufacturers, in the process of preparing zirconia slurry, the dispersant selected is not the same, so not a dispersant can solve the problem of dispersion of all ceramic powders, and the dispersant of metal ions cannot be had. Of course, all products still have to be tested to determine whether they are usable, and practice is the standard to test whether the product is feasible. Our Aoda's zirconia dispersants can stand the test, choose Aoda's environmental protection new materials, you will not be disappointed.

As a kind of ceramic powder, zirconia powder has the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient, making it an important high-temperature resistant material and ceramic insulating material. However, zirconia itself is very polar, the finer the particle size, the greater the influence of van der Waals force, and the more serious the agglomeration or preparation of zirconia slurry through the layer, so the use of appropriate zirconia dispersant can solve the problem of zirconia powder agglomeration.

Shizukawa Chemical's zirconia dispersant is different from the traditional dispersant, it has functional groups that can quickly combine with the surface of zirconia powder to form stable chemical bonds, and at the same time apply mechanical force to the agglomerate of zirconia at the same time, it can quickly wet the surface of zirconia, reduce the surface energy and force of zirconia powder, achieve the effect of dispersion, and reduce the viscosity of zirconia slurry. The grinding process of zirconia powder is also related to the pH value of the slurry, the particle size of the powder, the solid content and other factors.

Which fan G is suitable for dispersing zirconia powder ink, and it is more appropriate to use C-type fan G.

Good evening, the particle size has reached hundreds or tens of nanometers of solid particles with a large specific surface area, it is easy to agglomerate through electrostatic adsorption, so the ball mill planetary machine must add a small amount of surfactant to disperse when grinding this powder, otherwise the effect is not good, and it is very easy to agglomerate when it encounters moisture when it is not added, please refer to it. Generally, several pigments used in inkjet printer pigment inks can quickly increase the ratio when the particle size is less than 1um.
