SELECTION OF CANOPY SEAL ANTI FREEZE LUBRICANT,
Abstract
The shearing force required for breakaway of a 12 x 12 inch 7075-T6 aluminum alloy plate supported by two of its edges by the flanges of 1 x 1 inch 7075-T6 aluminum alloy angles and separated from them with anti-freeze lubricants was used to estimate the seizure characteristics of the various lubricants. During test, a block of solid carbon dioxide was placed on the 12 x 12 inch plate to induce a low temperature at the sliding surfaces. The lubricants tested were water, glycerol, petrolatum, Dow Corning DC silicone oil, n-hexanol and ethyl propionate. The breakaway forces for each lubricant were as follows: water, 45.0 lb.; glycerol, tin film, 43.2 lb.; glycerol, thin film, 43.2 lb.; thick film, 15.8 lb.; petrolatum, thin film, 13.1 lb.; petrolatum, thick film, 32.3 lb.; DC-4 silicone oil, thick film, 6.6 lb.; n-hexanol, 17.6 lb.; and ethyl propionate, 18.0 lb.
