Whiteness Resolution and Dispersion of Titanium Dioxide Food Grade:
Dispersion of food-grade titanium dioxide is an extremely important property of titanium dioxide. Food-grade titanium dioxide has hydrophilic and oil-thinning properties. It is poorly dispersed in synthetic resin organic system and needs surface treatment to improve its dispersibility. In order to improve the dispersion of titanium dioxide in macromolecule media, it is necessary to carry out organic coating treatment to make it have the surface of organophilic substances. In order to improve the dispersion of titanium dioxide particles, a macromolecule adsorption layer was established on the surface of titanium dioxide particles to form a space barrier, which prevented the pigment particles from approaching each other.
Whiteness Analysis of Titanium Dioxide Food Grade 食品级二氧化钛
Whiteness analysis of edible titanium dioxide; whiteness is the ratio of absorption to reflection of visible light, and relative whiteness is a function of wavelength and particle size. Whiteness combines the brightness and hue of white pigments
