  • Good Fineness Of Water Based Pigment Paste - China

    price: 7.60 Dollar US$

    The water-based pigment paste fineness is an important technical index to measure the pigment paste quality. Pigment paste fineness inculdes two parts: one is the size of pigment paste particles; another one is the uniformity of particles.
    Through the role of dispersant, wetting agent, emulsifier and other agents, pigment particles in pigment paste slowly forms the small suspended particles after strong shear force of grinding machines in water based system. At last, pigment paste is produced.
    According to the experience of coatings engineers, the smaller of pigment paste particles, the better of fineness, and the pigment paste coloring strength is higher. However, the finer of pigment paste fineness, the higher request to dispersion equipment, dispersion medium and the dispersion time. Pigment paste manufacturers should pay more costs for the production of pigment paste. Also the uniformity of pigment paste fineness is very improtant quality indicator. So how to detect the pigment paste fineness by us?
    1. To observe the fineness of water-based color paste with a microscope, is the most commonly method to detect the fineness of aqueous pigment colorpaste. Usually, the inspectors of pigment paste manufacturers use a magnification of 640 times the biological microscope, eyepiece contains one tenth of the micrometer. The fineness of the pigment paste is observed with the micrometer.
    2. Observe the pigment paste fineness with advanced particle size analyzer.It is more easy.
    3. Direct comparison in the application. Prepare a paint formula of 5% pigment paste added amount, another formula is inculding 0.02% pigment paste adding amount. Then scrapes on the substrate. To compare the color strength, the better coloring strength, the better pigment paste fineness.
    The pigment paste grinding technology and equipment of Shanghai Caison Color company is leading in the industry, so the fineness of pigment paste is very fine and uniform, the average particle size would be reach 1 micron.
