发明名称 Method for characterizing the neutralizing capacity of a lubricant and apparatus for carrying out this method
摘要 <p>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</p>
