因應工業4.0智慧生產與自動化製程，為達到提高生產效率與機械穩定性，有效的潤滑是相當重要的課題，本論文研究水分與顆粒對潤滑脂劣化之關係並利用一個快速、方便的光學檢測設備進行實際量測，可即時監控其潤滑脂性能變化了解潤滑脂使用狀況，藉此判定此機台是否需進行保養維護，進而大幅提升生產效率及有效降低生產成本。
本文實驗為添加水分與顆粒後觀察水分與總酸價之變化過程，再經由四球磨耗加速潤滑脂劣化後觀察磨痕直徑、鐵粉濃度及特徵值的改變。經由實驗結果顯示鋰基潤滑脂的總酸價與水分之關係，當水分增加總酸價也隨之上升，當水分0.6 wt%時已超過總酸價更換潤滑脂標準；而添加不同比例水分經四球磨耗實驗後後總酸價上升兩倍，情況相當嚴重已達到立即更換需求；在四球磨耗實驗中顯示在水分1.0 wt%時潤滑脂完全乳化後摩擦係數隨之上升，且磨痕直徑與摩擦係數趨勢吻合；在光學檢測部分當添加0.6 wt%特徵值A下降51 %，而特徵值C在添加1.0 wt%偏移44 %表示潤滑脂完全乳化。
添加不同奈米顆粒將造成總酸價的上升，除了添加Al2O3 20 nm造成總酸價下降，而其中在相同顆粒濃度下對於總酸價上升影響最嚴重的為Fe2O3 30 nm，其次為Fe 800 nm與 SiO2 1000 nm，最後為SiO2 15 nm，而在相同奈米顆粒之下顆粒直徑越大對於總酸價的影響越大；而添加奈米顆粒後進行光學檢測，在添加相同1000 ppm濃度下Fe2O3在特徵值A下降幅度最為明顯，添加Fe2O3特徵值A下降32.5 %；添加Al2O3時在特徵值B下降最為明顯下降了8.7 %，而添加鋰皂基添加水分實驗中特徵值B下降了1.2 %，唯有添加Al2O3響應最大，推測未來可用此特徵判斷滑脂中是否含有此種顆粒。

In order to improve production efficiency and mechanical stability in response to Industry 4.0 intelligent production and automation processes, effective lubrication is a very important issue, this paper studies the relationship between moisture and particles on grease degradation and uses a fast and convenient optical inspection device for actual measurement, instantly monitor changes in grease performance to understand grease usage, it can be judged whether the equipment needs maintenance and maintenance, thereby greatly improving production efficiency and effectively reducing production costs.
This experiment is to observe the change of water and total acid value after adding water and particles, observing the change of wear scar, iron powder concentration and characteristic value after the deterioration of grease is accelerated by four-ball test. The experimental results show the relationship between the total acid value of lithium grease and water content, when the moisture increases, the total acid value also rises, when the moisture is 0.6 wt%, the total acid value has been replaced; Adding different proportions of water after the four-ball abrasion test, the total acid value doubled, the situation is quite serious need to replace the grease immediately; In the four-ball test, the friction coefficient increases as the grease is completely emulsified at 1.0 wt% of water content, and the grease is replaced immediately, And the wear scar is consistent with the trend of friction coefficient; In the optical experiment, the addition of water content 0.6 wt% characteristic value A decreased by 51 %, The characteristic value C increased by 44 % when 1.0 wt% of water was added to represent complete emulsification of the grease.
Adding different nano particles will cause an increase in total acid value, only the addition of Al2O3 20 nm causes a decrease in total acid value, which causes a decrease in the total acid value, and the most severe effect on the increase in total acid value at the same particle concentration is Fe2O3 30 nm, Followed by Fe 800 nm and SiO2 1000 nm, Finally SiO2 15 nm, the greater the particle diameter in the same particle condition, the greater the effect on the total acid value; Optical experiments were operated after adding nanoparticles, and the results showed that Fe2O3 had decreased a lot in characteristic value A at the same particle concentration of 1000 ppm, adding Fe2O3 characteristic value A decreased by 32.5 %; adding Al2O3 characteristic value B reduced 8.7%.
