A mixing system for pigment dispersions, colorants, paints, and coatings, including a mixing or dispersion blade having a disc having top and bottom surfaces and an outboard edge, vanes circumferentially spaced around and extending from the outboard edge of the disc, each vane oriented non-horizontal to the top surface of the disc, and a wear-indicating notch in at least one of the vanes; and a tank, the tank including a paint, pigment dispersion, colorant, or coating.

The present invention relates to a kind of pigment preparation, in particular to a modified layered silicate novel barrier and shielding pigment and its preparation method. It is a layer silicate with exchangeable anticorrosive ions as a template, using metal oxides or metal salts, inorganic acids to synthesize nano-spherical zinc phosphate, phosphate, molybdate, borate or tungstate, with rare earth cerium, strontium, lanthanum or praseodymium doped modification of the pigment. The invention uses silicate as a template to effectively control the agglomeration of nanoparticles during the liquid phase deposition process, avoiding the multiple cleaning and sewage treatment processes required by using surfactants and solvents. What is more valuable is lamellar silicic acid. The salt itself has certain anti-corrosion properties and is economical. At the same time, the physical barrier and exchangeable anti-corrosion ions of the lamellae further improve the anti-corrosion properties of the pigment, making the pigment highly active and shielding.
