As a wet grinding and dispersing solutions provider, LONGLY offers various machines including wet grinding machine, bead mill, homogenizing equipment to produce pigments and dyes.
In the dispersion/grinding stage, the pigment clumps are mechanically separated into smaller particles. The wetting and dispersing surfactants act synergistically, to ensure that the wetting of the smaller particles created happens faster and the particles do not clump again, so reducing process time and, consequently, energy spent.
Bead mill is a kind of super - fine grinding equipment for wet process, now it is widely used in ink, pigment dispersing and grinding. There are different kinds of bead mills, from the installation form, it can be divided into vertical and horizontal.
It is important to remember, though, that the choice of dispersing equipment is only one of many factors affecting the nature of the dispersion. Pigment selection is also critical. Different pigments exhibit different behaviors in different formulations, often times even if they appear to be identical.
Composition of the pigment paste made up for subsequent testing of dispersion quality. After grinding, clear lacquers are pigmented with the prepared tinters and applied onto clean glass plates. The ratio of the pigment to binder solids should be as follows: Inorganic pigments = 20-30%. Organic pigments = 10-15%. Carbon black = 5-10%. 3).

Dispersing additives, which adsorb on the pigment surface, facilitate liquid/solid interfacial interactions and help to replace the air/solid interface by a liquid medium/solid interface. The grinding process can be regarded as a de-flocculation process. In the absence of stabilizing agents, effects such as reduced color strength, decreased ...
A new and improved method for making a pigment dispersant system, a method for pigment grinding and a new pigment dispersant system are herein disclosed. The inventive compound and process do not use a resin or the harsh milling process used in current pigment technologies.
In the case of wetting and dispersing additives, this means that they do not come into contact with the actual pigment, they are in contact with the chemical surface treatment on the pigment. Therefore, in practice, if there are unsatisfactory grinding results with a specific pigment, the same pigment should also be considered with other ...

DISPERSION OF PIGMENTS AND THE NEED FOR EFFICIENCY The primary objective of dispersing pigments in a dispersion or grinding medium by mechanical means, is to separate the pigment agglomerates which are formed during the drying processes in pigment manufacture. As particle size is reduced, the surface area so created increases, leading
The requirements for dispersing agents therefore are as follows: • Support of grinding ⇒ short dispersing time, optimum degree of grinding. • Reduction of grind viscosity ⇒ high pigment content, fluidity. • Stabilisation of the dispersion ⇒ colour strength, gloss, colour shade stability.
Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.
In combination with the available material portfolio, the technology fits to almost any application in the wet grinding and dispersing industry. InNovaZ TRL-C Inline Disperser In 2016 invention patent, Chemical Engineering Society Technology Award was obtained.
· Resin 6529 possessed pigment grinding and stabilization capabilities very close to that of a polymeric pigment wetting and dispersing additive. In addition, when pigment tints based on Resin 6529 were used to replace pigment slurries in a 2K isocyanate-cured coating system, a number of key performance properties were improved.
