耐候防銹滑脂性能評估研究

The Evaluation of Weathering Resistant and Corrosion Preventive Lubricating Greases

本研究分別以滑脂揮發物含量、耐水沖性、鹽霧試驗、室外曝露試驗等多種測試評估15種市售與自製滑脂之耐候與防蝕性能。試驗結果顯示，一般實驗室內測試並不能與室外曝露試驗結果有直接關聯。本文建議以滑脂碳鋼抹片曝露試驗配合鹽霧試驗以評估其耐候防蝕性能。此外，於滑脂中添加腐蝕制劑DECHAN所產生之防蝕效果因滑脂本身種類不同而有極大差異。

A series of measurements including volatile matter content, water spray resistance, salt fog resistance and atmospheric exposure tests of 15 lubricating greases were performed. It appears that the data obtained from ordinary laboratory tests can not be directly correlated with those obtained from field exposure. A grease/carbon steel panel exposure associated with salt spray tests was recommanded to evaluate the weathering and corrosion prevention performance of greases. It is also found that the inhibitor DECHAN has great different inhibitive effects for various greases which depend upon the properties of the base greases.
