68号基础油
Zhonghai nanlian no.68 base oil is produced by vacuudistillatio, so**ent dewaxing and clay refining.
Its advantages are good sell, clear color, moderate viscosity, good storage stability and light stability
Used in the production of medium and high grade lubricating oil (including production of engine oil, hydraulic oil, gear oil, compressor oil, refrigerating oil, transformer oil, heat conducting oil, quenching oil, metal processing oil, etc.)
Application in ruer industry (as filling oil)
