Fremgangsmåde ved karakterisering af et smøremiddels neutraliseringskapacitet og indretning til udøvelse af fremgangsmåden

摘要

A film of lubricant is formed inside a sealed reservoir. A known quantity of acid is placed on the surface of the film in a time less than 0.5 second. The pressure inside the reservoir is recorded as a function of time until it stabilizes. From the recorded pressures, at least one of three parameters is determined: delay initializing the reaction, neutralization potential, speed of reaction
