Titanium pigment used in plastics, fiber has its special performance metrics. Titanium pigment is an important white plastic paint, it can make the plastic scattering light effectively and endowed with whiteness, brightness and opacity. At the same time, also want to consider its workability, therefore the above performance should have certain requirements. (1) whiteness Because plastic itself has a color and transparency, its whiteness are obviously different, so in all kinds of titanium white white degree of the contrast, dealing with the same variety in terms of plastic. (2) the opacity Titanium dioxide can strongly scattering or refraction of light, if in the plastic products contain enough titanium pigment, was all the light illuminate the surface reflection, is the product is not transparent and white. (3) the dispersion dispersion refers to the pigment dispersion force in the medium being shaded. Titanium dioxide particles exist in three states: native, condensed matter, aggregate particles. Titanium pigment dispersion in the plastic is the aggregate was broken into condensed primary particles and new generation process of particle stability. (4) machining titanium dioxide added to plastics, affect plastic processing rheological properties. Content is higher, the effect is more significant. In the production of white masterbatch (especially high concentration variety), titanium dioxide machining quality is key to the production efficiency and cost of the key factors. |
