MEASUREMENT OF OIL OR GREASEŚ SATURATION VAPOR PRESSURE WITH MATERAILŚ VOLATILIZATION AND CONDENSATE CHARACHER TEST FACILITY

A Quartz Crystal Microbalances are applied as a detector in measurement of oil or greaseŚ saturation vapor pressure based on principle of Evaporation Velocity Measurement Method. compared with the same method using Kenn Microbalances, it has the advantages of higher precision and easy operation. An existing facility wich a Quartz Crystal Microbalance which was designed for measurement of materialsŚ volatilization and condensate character under vacuum is used. A standard oil samples is taken into the test. Result of the test validates the measurement method.
