Abstract: The present invention relates to a process for making a polymer masterbatch with silica nanoparticles highly uniformly dispersed therein by using a stable aqueous emulsion of compatibilized silica nanoparticles, the sizes of which are mechanically reduced to nanoscales. Adequate reduction of the silica particles to nanoscales is essential for the formation of a desired emulsion of highly stability. The said emulsion of compatibilized silica nanoparticle can be easily mixed under mild conditions with a polymer in latex form, which can be high purity natural rubber, synthetic rubber and/or a blend thereof. The bifunctional organosilane coupling agent bonded-Silica nanoparticles are subsequently incorporated into the rubber polymer network during coagulation with formic acid. The inventive rubber-silica masterbatch thus obtained is useful for manufacturing rubber and other polymer composite products.

The capturing method for the images with different view-angles includes the following steps. An appearance image of an object is captured by an image capturing unit at a capturing angle. A light reflection area of the appearance image is detected by a detecting unit, and a dimension characteristic of the light reflection area is analyzed by the same. Whether the dimension characteristic of the light reflection area is larger than a first predetermined value is determined. If the dimension characteristic of the light reflection area is larger than the first predetermined value, then the capturing angle is adjusted within a first adjusting range. After the step of adjusting the capturing angle within a first adjusting range is performed, the step of capturing the appearance image is performed again.
