Two different technologies (direct mixing and three-roll milling) were applied to facilitate the dispersion of nano-ZnO in a nitrile rubber (NBR) composite. The vulcanization, mechanical, friction, and wear characteristics of the two resulting rubbers were studied. Wear surfaces were measured and analyzed via 3D scanning, scanning electron microscopy, and X-ray photoelectron spectroscopy. Results...
In this paper, superfine SiO2 nanoparticles are utilized as composite abrasive additive to improve the polishing property of CeO2, which is prepared through chemical precipitation method by rare-earth chloride as raw materials, silicofluoric acid as fluoride, Na2CO3 as modifier, and NH4HCO3 as precipitator. XRD, SEM, particle size analyzer, and atomic force microscopy are applied to characterize the...
