【摘要】：為了實現(xiàn)稻殼資源的綜合利用,變廢為寶,以稻殼和酚醛樹脂為原料,高溫碳化制備出稻殼基陶瓷顆粒(rice husk ceramic,RHC),將其作為潤滑油功能添加劑,可緩解稻殼焚燒和儲存給環(huán)境帶來的危害。在四球機上探究不同溫度(25、75和100℃)和司盤-80分散劑存在條件下,不同添加量(質量分數(shù)為0.01%、0.03%和0.05%)的RHC顆粒對液體石蠟(liquid paraffin,LP)潤滑特性的影響,進而研究RHC顆粒的摩擦學行為。結果表明,25和75℃下,RHC顆粒在一定程度上改善了液體石蠟潤滑性能,主要表現(xiàn)在鋼球表面磨斑直徑的降低,抗磨性增強,但并未明顯降低摩擦系數(shù);100℃下,RHC顆�？擅黠@改善液體石蠟的潤滑特性,添加量為0.01%、0.03%和0.05%的油樣與純液體石蠟相比,平均摩擦系數(shù)從0.139(LP)分別降低到0.083、0.064和0.069;平均磨斑直徑從0.389 mm(LP)分別降到0.314、0.311和0.318 mm。高溫下摩擦誘導RHC顆粒組分參與邊界潤滑膜形成,起到抗磨減摩的功效。RHC顆粒可作為潛在的高溫潤滑油摩擦改進劑。
