Effect of Polyethylene Crosslinking and Bearing Design on Wear of Unicompartmental Arthroplasty.
Wear and polyethylene damage continue to be important factors affecting outcomes of unicompartmental knee arthroplasty. We compared two design rationales for unicompartmental arthroplasty: fully congruent mobile bearings; or moderately conforming fixed bearings using experimental and computational wear simulation. Experimental wear rates were 3.89 (±0.12) mg/million cycles for the highly crossl...
متن کاملThe Effects of Different Silane Crosslinking Approaches on Composites of Polyethylene Blends and Wood Flour
Though silane chemistry has been used to crosslink unfilled polyethylene for many years, such crosslinking has only been recently applied to wood plastic composites to improve properties such as creep resistance. However, the presence of wood significantly changes the silane chemistry and a greater understanding is necessary for optimal processing and performance. We investigated three differen...
متن کاملThe trapping characteristic of low density polyethylene in the presence of crosslinking by-products
The by-products of dicumyl peroxide (DCP) from the crosslinking process such as acetophenone, cumyl alcohol and α-methylstyrene are said to be the sources of space charge formation in XLPE cable due to deep traps in the chemicals. However, by using space-chargeexperimental approach, it appeared that these chemicals show a different trapping nature. This paper is intended to present this approac...
متن کاملPolyethylene Wear Debris From a Knee Simulator Model: Effect of Crosslinking and Counterface Material
INTRODUCION: Improved wear resistance of crosslinked UHMWPE has been well demonstrated in both hip and knee [1-4]. A reduction of 70% can be shown in knee simulators from conventional crosslinked tibial inserts (CXPE) gamma-irradiated at 3.5Mrad to 7Mrad highly crosslinked inserts (HXPE). Hip simulator models indicated that debris size decreased with increased crosslinking [5]. In the knee it h...
متن کاملAnti-crease finishing of cotton fabrics based on crosslinking of cellulose with acryloyl malic acid.
Maleic acid (MA) has been explored to replace formaldehyde-based dimethylol dihydroxy ethylene urea (DMDHEU) for cotton anti-crease finishing. However, the resilience of treated fabrics was not satisfactorily improved. In this study, acryloyl malic acid (AMA) was synthesized and applied on fabrics as a novel crosslinking agent. The results showed that both crease recovery angle and whiteness in...
