莱宝扩散泵油技术参数:
leybonol pump fluids for oil diffusion pumps must exhibit a low vapor pressure at room temperature
and must be able to resist thermal decomposition and oxidization. they permit high pumping speeds
over a wide range of pressures.
surface tension of the pump fluids must be high to reduce creep of oil films. they are chemically inert,
exhibit a high flash point and the evaporation heat is low.
