填料填充对UHMWPE交联塑料磨粒磨损性能影响

he paper used silica, carbon black and reduced iron powder of three fillers filled UHMWPE crosslinking system modified.Prepared by compression molding and sintering forming the modified cross-linked UHMWPE plastic.Testing cross-linked plastic gel rate, abrasive wear resistance and tensile strength of the modified UHMWPE .The experimental result indicated:When the silicon dioxide content 6%, carbon black content 8%, reduced iron content 2%, the abrasive rate of wear is smallest. In the abrasive attrition experiment, reduced iron content to be biggest to the abrasive rate of wear influence. In the longitudinal strength experiment, the silicon dioxide content is biggest to the longitudinal strength influence. In degree of hardness experiment, the silicon dioxide the influence is biggest to degree of hardness.
