style="text-indent:25px">工程車(chē)專(zhuān)門(mén)用的油的特性是怎么樣的？1.理化性質(zhì)：外觀（色度）油品的顏色，往往可以反映其精制程度和穩(wěn)定性。對(duì)于基礎(chǔ)油來(lái)說(shuō)，一般精制程度越高，其烴的氧化物和硫化物脫除的越干凈，顏色也就越淺。但是，即使精制的條件相同，不同油源和基屬的原油所生產(chǎn)的基礎(chǔ)油，其顏色和透明度也可能是不相同的。對(duì)于新的成品潤(rùn)滑油，由于添加劑的使用，顏色作為判斷基礎(chǔ)油精制程度高低的指標(biāo)已失去了它原來(lái)的意義。2.密度是潤(rùn)滑油較簡(jiǎn)單、較常用的物理性能指標(biāo)。機(jī)油的密度隨其組成中含碳、氧、硫的數(shù)量的增加而增大，因而在同樣粘度或同樣相對(duì)分子質(zhì)量的情況下，含芳烴多的，含膠質(zhì)和瀝青質(zhì)多的潤(rùn)滑油密度較大，含環(huán)烷烴多的居中，含烷烴多的較小。3.粘度反映油品的內(nèi)摩擦力，是表示油品油性和流動(dòng)性的一項(xiàng)指標(biāo)。在未加任何功能添加劑的前提下，粘度越大，油膜強(qiáng)度越高，流動(dòng)性越差。深圳高性能工程車(chē)用油現(xiàn)價(jià)</p><p
