Nano Color Paste Grinding Process

Nano color paste grinding process

In the design of industrial products, creativity, design and usability are very important, but the product color is particularly critical, because the expression of color can greatly affect people's preferences, and the perfect performance of color is an important task for pigment manufacturers.

As a result, the nano color paste came into being, when the color powder particles in the color paste are ground to the nanometer fineness, the color paste becomes transparent, transparent color paste bright and transparent, high saturation, high coloring strength. The most critical factors affecting the quality of the color paste are dispersion and grinding.

Nano color paste dispersion
As we all know, the dispersion state, surface polarity, particle size and particle size distribution of pigment particles will directly affect its storage and application performance. The quality of dispersion not only affects the coloring power and hue, but also may have a certain impact on the optical stability of the coating.

What does dispersion mean? It is to "break" the original large particles of pigment particles by applying external forces, and "separate" the reunited particles, so that it is infinitely close to the size of the original particles, evenly dispersed in the paint, and ensure that all the particles are fully covered by the paint.

When the toner is evenly distributed in the paint in the form of small particles and large surface area, the toner particles are fully surrounded by the paint and isolated from each other, the attraction between each other is weakened, and it is no longer easy to reassemble into large particles, so as to achieve a stable state. At the same time, the overall coloring power and hiding power of the color paste will be improved, and the luster and smoothness of the film are better.

Nano color paste grinding
Grinding is to grind the color powder fine, improve the dispersion performance of the color paste through a finer particle size, and improve the color characteristics of the color paste (such as transparent highlighting) and performance (such as improving the coloring force strength).
After fine grinding, the color development performance of the powder particles has been improved. With the extension of grinding time, the transparency and color saturation of the paste in the varnish are gradually improved.

The equipment of Peng-wing grinding dispersion has been tested and adjusted for many times, and can achieve "just the right grinding balance point".
