[Announcement] Mr. Hayashi of Sojo University’s Satonaga Laboratory receives the “Outstanding Student Presentation Award”

Mr. Hayashi of the Satonaga Laboratory at Sojo University, who is conducting basic research on the oil additive SOD-1, received the “Outstanding Student Presentation Award” for his presentation on lubrication research.
We at D1 Chemical are very pleased and would like to offer our heartfelt congratulations.

■Research Presentation Overview

In rotating machinery used in production facilities, bearing damage is often the main cause of failure, excluding accidental breakdowns, and extending the life of bearings greatly contributes to extending the life of the entire machinery. For this reason, improving the performance of lubricants has become an important research topic.

In this study, the lubrication state of bearings under complex operating conditions, including repeated forward/reverse rotation and stopping, was observed and evaluated using electrical contact resistance (ECR) methods and other methods.

The following trends have been reported in comparative tests between a standard oil (5W-30) and a sample oil to which 10% SOD-1PN has been added.

・Addition of SOD-1PN tends to improve oil film separation
・Frictional resistance tends to decrease
・The oil film tends to be maintained even under stop-start conditions

SOD-1 improves oil film retention, protecting areas prone to friction and wear and reducing stress.

 The results of this research highlight the importance of oil film retention in lubrication environments and are expected to contribute to future advancements in lubrication technology.
At D1 Chemical, we value the knowledge gained through these research activities and will continue working to develop better products and advance lubrication technology.
