Pearlescent pigment is coated mica sheet metal oxides, can produce pearl luster pigment, appearance is transparent, powder flat, having a larger diameter and smooth surface and high refractive index properties than general pigment. The product is a powder, non-toxic, tasteless, acid and alkali resistant, non explosive, non-conductive, no arc starting, has a high heat resistance (900 ℃) weather resistance and higher: has good luster, the average effective refractive index of 2.5, where the iron series products up to 3.
One, main uses:
With the development of pearlescent pigments, pearlescent pigmentapplication is more and more recognized, can be used in automobile, bicyclepaint, decoration paint, ink, leather, pearly pearlescent pearlescentpearlescent plastic products, cosmetics, can also be used in papermaking,printing and dyeing, printing, printing, crafts, rubber, ceramics and other industries. Printing ink: pearlescent pigments and pigment, widely used in a variety of printing inks, the paper, cardboard, plastics, textiles, wallpaper addelegant pearl luster. Pearlescent pigments have different kinds of particles,depending on the printing process, the appropriate choice. Pearlescent pigments can be used alone or with other transparent pigment or dye used in conjunction, printed a variety of high-grade packaging and printing products,in order to obtain a series of colorful products. Two, main products series:
(1) silver white series: according to the type of titanium dioxide, encapsulation efficiency and the particle size is different, can be of various types of silverwhite pearl luster pigment, large particles showed flashes of dazzling metallic luster, small particles show a silky soft in color, you can also use titanium dioxide crystal type according to different needs. If the weather effect, pearlluster pigment can choose metal rutile TiO2 coated mica.
(2) the rainbow color series: this series pigments can show different rainbow like colors, this effect is produced by the interference color of light. Change with the change of the thickness of TiO2 coating, when the light to the surface of the pigment, a portion of the light will be reflected (assume for the red light),another part of the light (the red light) can penetrate, thus forming different reflex and transparent color.
(3) color series: this series pigments is pearlescent pigment special covered with a layer of titanium dioxide on the surface of mica and then covered with a layer of other transparent pigment combined, it not only has the pearl luster,but also with the transparent pigment has the attractive color.
(4) the mica iron series: mica iron series pearlescent pigment is on mica surface covered with a layer of oxide film directly according to the iron oxide coating thickness in different production of bronze, red brown, red, purple,green and red wine, interference color, bright color, strong gloss, tinting strength, although it is a non metal, can produce metallic luster.
(5) metal series: this series pigments is covered with a layer of titanium dioxide in natural mica surface, covering a layer of iron oxide, not only has the pearl luster, but also with iron oxide with color.
