Lanke Langfang: Titanium dioxide is the ink quality "guardian guardian"

Ink industry is an important application field of titanium dioxide, which is second only to apply coatings, plastics, paper and other three users. Titanium dioxide is used as a pigment is applied to the ink. As the pigment, which was first dispersed in a film-forming substance (binder), and then cover printed on the surface, so that colored objects. Including film-forming material between molecules and between molecules are not bound to the object of titanium dioxide molecules are colored. That's right the physical indicators and indicators of titanium dioxide pigment made high demands; the other is made of titanium dioxide in the inert whether there is sufficient, that the application process will not affect the properties of the system or product the nature of products, in order to permanently maintain the ink color and gloss produce. Since the most important role to play in the ink dioxide pigments, titanium dioxide that affect the performance characteristics of color and color strength of the ink quality is particularly critical. Let's talk about the color of titanium dioxide. We know, as a coloring pigment material, the first feature is colorful, bright, saturated, which is manufacturing the ink pigment primary selection criteria. The so-called saturation, hue refers to the degree of purity, the more pure color, in the human sense to feel more nuanced, and titanium dioxide is the world found the whitest white pigment, which also determines the titanium dioxide as white pigment in the ink of the raw materials used irreplaceable position. Coloring titanium dioxide ink performance also plays a key role. The so-called coloring it, is to make the ability to be colored in coloring matter. Coloring titanium dioxide determines the significance and the economic value of its use as a pigment. Coloring pigment strength depends on its structure, preparation method, dispersion performance. The color strength level, but also directly affect the ink: color strength is low, a large amount of pigment, ink solids content increases, reducing the scope for adjustable ink performance is not conducive to adjust ink. At present, the ink dedicated titanium dioxide coloring often very good, not only save the amount of the pigment, but also to enhance the performance of high-quality play of the ink. So to speak, the color and color strength titanium dioxide play a role in the production of the two right-hand man of the ink, but also to ensure the quality of the two ink "Performance Guard."
