摘要

研究了润滑油的流变特性及其对滑动接触的摩擦学影响。采用有机聚合物石竹羧甲基纤维素(EC-CMC)聚合物作为玉米油(CO)和葵花籽油(SFO)的添加剂。实验采用高频往复钻机(HFRR)进行。用EC-CMC浓度(0.5 wt;%, 1 wt。%和1.5 wt.%),在100毫升体积的基础CO和SFO样品下。聚合物浓度的流变学研究表明,0.5 wt时效果良好。%, 1 wt。%, 1.5 wt。%,但在1 wt时显示最佳。% EC-CMC特别适用于温度超过100°C的两种选定润滑剂。在摩擦磨损分析下,使用1 wt进行试验。% EC-CMC。基础润滑剂CO和SFO的摩擦磨损系数和磨痕直径分别为0.087、11.2 × 10−6 mm3/N/m和0.080、10.5 × 10−6 mm3/N/m。在测试过程中,使用1 wt。% EC-CMC共混SFO在基态和加入添加剂时的摩擦系数都低于CO。这产生了COF减少22.5%和13.8%为1吨。% EC-CMC + SFO和1 wt。% EC-CMC + CO,但在SAE-5W-30下还原效果更好。分析得出,应用1 wt。在基础油润滑油中加入%的EC-CMC,对SFO和CO的性能都有显著提高。这种可持续产品的利用肯定会有助于解决全球污染挑战。

Tribological performance evaluation of organic polymer as additives in vegetable oil using steel materials
An investigation on lubricating oil rheological behavior and tribological effect on sliding contact was conducted. The study employed organic polymer Eichhornia Crassipes carboxymethyl cellulose (EC-CMC) polymer as additive in corn oil (CO) and sunflower oil (SFO). The experiment was performed using high frequency reciprocating rig (HFRR). Analysis on viscosity behavior was done with three samples of EC-CMC concentration (0.5 wt.%, 1 wt.%, and 1.5 wt.%) under 100 ml volume of base CO and SFO samples. Rheological studies on the polymer concentrations show good results with 0.5 wt.%, 1 wt.%, and 1.5 wt.%, but indicated optimal on 1 wt.% EC-CMC especially from temperature beyond 100°C for the two selected lubricants. Under friction and wear analysis, the test was conducted using 1 wt.% EC-CMC. The base lubricants CO and SFO yielded coefficient of friction and wear scar diameter of 0.087, 11.2 × 10−6 mm3/N/m and 0.080, 10.5 × 10−6 mm3/N/m, respectively. During the testing, the use of 1 wt.% EC-CMC blended SFO gives lower coefficient of friction than CO both at base state and inclusion with additive. This yielded COF reduction by 22.5% and 13.8% for 1 wt.% EC-CMC + SFO and 1 wt.% EC-CMC + CO, respectively, but gives better reduction under SAE-5W-30. The analysis concluded that application of 1 wt.% concentration of EC-CMC in base oil lubricant for both SFO and CO significantly enhanced the properties. The utilization of this sustainable product certainly will contribute in solving global pollution challenges.

期刊介绍: The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there." Professor Rob Dwyer-Joyce, Sheffield University, UK This journal is a member of the Committee on Publication Ethics (COPE).
