Osmosis and the Kinetics of Percolation of Petroleum Products Through an Epoxy Adhesive

摘要: Abstract A moire optical interference method has been used to investigate the dimensional changes that occur in an FM1000 epoxy adhesive joint between a microscope cover slip and block of glass during exposure dried 99% n-octane, kerosene and, simultaneously, plus water. The immediate response n-octane uptake is shrinkage around edge joint. Within 2 hours at 60°C octane permeated right across give distribution fringe loops indicative local swellings. activation energy deduced from temperature dependence this permeation time 14 kcal mol−1. Examination reveals presence clusters particles beneath each region swelling crossed polars, strong photoelastic contrast adjacent particle. These observations are similar those for same commercial indicate both cases should be attributed interaction ...
