Sandy Finish vs. PVC Dot Grip Gloves: Palm Friction Mechanics in Viscous Fluids
Introduction: Hydrodynamic Boundary Failure in Heavy Industrial Applications In onshore and offshore oil and gas drilling and production turret operations, the assembly and disassembly of high-pressure fracturing sand-mixing manifolds, the overhaul of heavy-duty industrial gearboxes, and the final assembly workshops for large-scale power equipment, field workers’ hands are constantly in contact with thick, viscous fluids. Heavy crude oil, high-solid synthetic-based drilling fluids (SBM), polymer-thickened slurry, and extreme-pressure gear grease not only exhibit strong adhesion but are also typical non-Newtonian fluids. Under heavy-duty conditions, when workers use their hands to lift, tighten, or turn metal components coated with such high-viscosity media, a critical shift occurs in interfacial forces: the lubricating fluid […]
