W artykule przedstawiono wyniki badań skuteczności odolejania na membranach ceramicznych firmy TAMI według wymagań Rez. MEPC IMO 107/49. Przedstawiono pomiary stężenia oleju przed i za membraną oraz rozkład objętościowy cząstek wykonane miernikami Malvern 2000 i Horiba. Otrzymane wartości są mniejsze od 15 ppm.

This article presents the results of tests performed to examine the efficiency of oil separation with the use of TAMI-made ceramic membranes Rez. MEPC IMO 107/49. The measurements, done with a Malvern 2000 and Horiba measuring instrument, aimed at the determination of oil concentration before and after the membrane filtration and, additionally, yielded the volume distribution of particles. The obtained values are lower than the admissible ones, i.e. 15 ppm.

With the aim of enabling the easy spinning of polysulfonamide (PSA) fibers, FFL-13 oil was successfully prepared. Specific resistance, the coefficient of friction, carding machine, electrostatic, cohesion, scanning tunneling microscopy (STM), and Fourier transform infrared (FTIR) spectroscopic analyses were conducted in this study. Results showed that increase in oil concentration, ambient temperature, and humidity induces decrease in PSA fiber-specific resistance and gradual increase in the antistatic property. Relatively high oil concentration and ambient humidity may cause fibers to become sticky and show increased roller winding. As oil concentration increased, fiber cohesion increased and fiber gliding properties showed an initial increase and subsequent decrease. The ideal oil concentration was determined to be 0.6%. This study proves that STM may effectively be used to determine the optimal oil concentration.
