demands: viscosity in a range of 9.3–12.5 mm
2 /s, price is lower than 20 yuan/kg and
plant base oil content not less than 50%.
After nearly one year of storage under natural conditions (high temperature and
humidity in summer; large temperature difference between day and night in autumn;
cold and wet in winter), the testing results showed that the quality index (Table 7.2)
of L-RD-4-2 lubricant antirust oil meets the requirements of the SH/T 0692-2000
standard.
The lubricant antirust oil has the characteristics of stable quality, excellent
performance, and easy use, and is a product with broad application prospects.
The properties of bio-lubricant can be improved by the introducing additives such
as viscosity modifiers, detergent and dispersant additives, extreme pressure and antiwear additives, antioxidants and other additives, depending on the requirements of
the application. The main blending mechanism of lubricating oil is summarized, and
the intermittent and continuous blending of lubricating oil is compared. L-RD-4-2
lubricant antirust oil blended by plant-based oils and additives has excellent performance. With people’s attention to the environment, bio-lubricants will be widely
studied.
