惠丰企业生产的真空油采用优质的基础油和进口添加剂调配而成,是一种理想的润滑材料,广泛应用于我国军工企业、显示行业、照明行业、太阳能行业、镀膜行业、制冷行业、航空航天等。
※ 较低的饱和蒸汽压,馏程窄,分子量大,抽速大。
※ 当油加热到沸腾状态下油将以超音速喷射并能较快达到真空目的。
※ 化学组成合理,具有良好的氧化安定性和热安定性。
※ HFV- K返油率较低,油蒸汽遇到冷壁后能迅速冷凝成新的工作液。
※ Low saturated vapor pressure,narrow distillation range,high molecular weight and pumping speed.
※ When heated to its boiling point,the oil will eject in supersonic speed to create a vacuum environment rapidly.
※ Reasonable chemical compositions, perfect oxidation and thermal stability.
※ Low back-streaming rate,oil vapor will condense into new fluid as soon as it touches cold wall.
※ HFV-K扩散泵油主要用于蒸汽流油扩散泵,并根据到达压力的要求可选择不同分子量的扩散泵油。
※ 适用于真空蒸馏、真空冶炼、真空镀膜、真空熔炉等等。
※ 可作为电子、航天、核工业等行业所用扩散泵的工作液。
※ Suitable for vapor diffusion pumps,it is available according to the final pressure only.
※ Applicable to vacuum distillation,vacuum metallurgy,vacuum coating, vacuum furnace, and etc.
※ Also be used as working fluid of diffusion pump in industries,such as electronics, aeronautics, nuclear and etc.
