Pigments appear colored because they selectively reflect and absorb certain wavelengths of visible light. White light is a roughly equal mixture of the entire spectrum of visible light with a wavelength in a range from about 375 or 400 nanometers to about 760 or 780 nm. When this light encounters a pigment, parts of the spectrum are absorbed by the pigment.
Oct 03, 2000· In the previous example, processing using dispersions would have been 120 min., rather than the 450 min. required grinding pigments. Why Grind It? Using dispersions rather than grinding pigments optimizes the production process and lowers process times, thereby providing better use of equipment and personnel.
Why do we use wetting and dispersing additives? One of the most important steps in the production of pigmented coatings is the homogeneous distribution of solid pigments within the liquid binder solution. If this pigment grinding step is not optimized, a wide variety of defects can occur: Flocculation Gloss reduction Color shift Separation,

In mineral form, titanium dioxide is often deeply coloured due to elemental impurities. Ground mineral rutile found some use as a colored pigment, but difficulties in grinding result in coarse particles with a different morphology than that of synthetic material. Naturally occurring anatase and brookite are not used for pigment manufacture.
Saint-Gobain ZirPro has been supplying high-quality ceramic media to the pigments, dyes and dispersions industries for more than 40 years. ZirPro offers a market-leading range of media (ER120, Rimax ®, Zirmil ® Ce and Zirmil ® Y) to meet the exacting demands of grinding and dispersing processes.Selection of the optimum bead (density and size) is critical, as color strength is closely …
DuPont Pigment Dispersion in Liquids The process of dispersing pigments in a liquid can be divided into three phases: Phase Measured by Initial wetting Mix-in-time Breaking of aggregates Fineness, gloss, tinting and agglomerates strength, transparency Flocculation Suspension, consistency, gloss, hiding, fineness under microscope, partial-set ...
The Importance of Particle Size in Liquid Coatings. ... The most common example is a coating pigmented with titanium dioxide and a colored pigment, especially an organic, will develop more color when the applied wet film is subjected to additional energy. ... The reason is that while grinding in the silica, the silica already in the system was ...
Request Expert. Expert has expertise in the product development and manufacturing of special effect inorganic pigments.He has developed the " sparkle" effect used by Colgate and Crest toothpaste and was the first individual to successfully put a metal oxide coating on a non mica substrate which lead to the development of glass, aluminum and titanium flake pigments.
Mar 16, 2019· Tinting strength refers to the ability of a mixture of titanium dioxide and another pigment to reveal its own color. In general, the basic paint of white toning is prepared with titanium dioxide, and then the color paste is added to the basic paint before coating to conduct on-site toning. ... When grinding and dispersing in the paint ...
Mar 12, 2015· We have been producing titanium dioxide pigments by grinding, which also produces some nanosize particles, and so we've been exposed to …
The ultra-fine grinding of pigments places high demands on the machine technology to be employed. The finest, absolutely grit-free granulation, low-residue processing with minimal contamination, as well as fast, thorough cleaning when switching products are the minimum requirements.
Some suggest that the resistance of titanium dioxide pigments to acids and alkalies is an advantage for their use in true fresco. Oil Absorption and Grinding Titanium dioxide absorbs a moderate amount amount of oil. The oil absorption ratio is 15–20 parts by weight of oil to 100 parts by weight of pigment.
The solid/gaseous interface ( pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: Through mechanical energy (impact and shear forces), the pigment agglomerates are broken up and disrupted into smaller units and dispersed (uniformly distributed).
13.3.2 Grinding or breakdown of particle clusters. Pigment particles do not usually exist as primary particles but instead as aggregates or agglomerates. Reduction of these clusters to primary particles is necessary in order to obtain optimum visual, economic and performance properties of pigments.
Pigment Size AN209 Pigment Particle Size and Hiding Power Particle size is intimately related to hiding power in pigments. Due to its speed and wide size measurement range, laser diffraction is an ideal tool for tracking the grinding process and therefore controlling the resulting pigment performance.
Why do we use wetting and dispersing additives? ... If this pigment grinding step is not optimized, a wide variety of defects can occur: ... Pigments in a pigment blend separate from each other. Organic red pigment and titanium dioxide; separation is made visible by conducting the rub-out test. Settling: It is easier for larger (flocculated ...
Most pigments used in inks and coatings, for instance, have a primary particle size from 20 to 200 nanometers, meaning that many operators of bead mills are already grinding …
High Speed Dispersion of Titanium Dioxide Titanium dioxide (TiO2) is chemically inert and has exceptional opacity and whiteness. These properties have led to its widespread use in many industries. ... TiO2 is usually supplied in powdered/premicronized form and particle size reduction (grinding) is not applicable in most cases.

Mar 16, 2016· But Titanium dioxide pigment becomes too heavy,and stringy (nearly for all synthetic pigments) no mater how much I grind it(by 3 roller mill). I was thinking to sell them in future,so its better to be in same volume and weight. I think I need a filler which absorb more oil,according to your article.And I dont know what it is.
GRINDING of TITANIUM DIOXIDE (TiO 2) GRINDING with ROLLER PRESS with ROLLER PRESS Because of his high index of refraction, the Titanium Dioxide is the most used white pigment. With an optimum size of particles (generally 0,2 to 0,3µm), this
