河北珠光纸厂

珠光纸的构成和普通白板纸相同，即由底层纤维、填料和表面涂层三部分组成。与普通白板纸不同的是其表面涂层中有形成珠光效果的颗粒。该颗粒由二氧化钛（或是其它金属氧化物）和云母颗粒组成，云母颗粒被二氧化钛（或其它金属氧化物）包裹而形成，此结构呈薄片状。

The composition of the pearlite paper is the same as that of the ordinary whiteboard, which consists of three parts: the bottom fiber, the filler and the surface coating. Unlike ordinary whiteboard, there are particles in the surface coating that form the effect of pearlite. The particles consist of titanium dioxide (or other metal oxides) and mica particles, and mica particles are formed by coating titanium dioxide or other metal oxides.
