Design Of Sand Mill For Pigment Dispersion

  • How to disperse and stabilize pigments

    The dispersion of a pigment in liquid coatings, paints or inks to produce stable suspension, can be divided into the following three processes: Mechanisms in the dispersion process Pigment wetting : All of the air and moisture is displaced from the surface and between the particles of the pigment aggregates and agglomerates (clusters) and is

  • Pigment Dispersion: Wetting & Dispersing Agents for Coatings

    Wetting & dispersing additives have an influence on this stage, by modifying the surface tension at the interface they can help and accelerate the pigment wetting. » Understand Substrate Wetting Theory Here! DISPERSING: The grinding equipment (dissolvers, grinding mills, sand mills) introduce mechanical energy in the system. This shear forces energy breaks and separates the pigment

    An agitator is a low-powered, high volume pump it is an efficient mixer. A typical dispersion application (such as dispersing pigment to make paint) requires about 1 HP for every 10 gallons compared to an agitator application (such as thinning the pigment dispersion with solvent) requires about 1

    Normally, this type of effect is experienced when a white base is tinted with a dispersion of the organic or colored pigment. If the resulting mixture exhibits a color change due to additional shear, the usual conclusion is that the organic color pigment dispersion had already been flocculated or that it flocculated in the white tint base due to chemical inadequacies with respect to either the

  • What is Pigment Dispersion Syndrome & How is it Treated?

    The colour of the eye is due to the presence of a pigment in the iris. In case of Pigment dispersion syndrome, this pigment is released from iris and it floats in the aqueous humour and clogs the trabecular meshwork. Pigment dispersion syndrome is a rare disorder of the eye. If diagnosed early, then to some extent, it is treatable.
