<p>　　潤滑油由基礎油(70%-5%)和添加劑(30%-5%)組成.<br style="font-size: 12px; white-space: normal; background-color: rgb(255, 255, 255); color: rgb(89, 88, 88); font-family: Arial, Helvetica, sans-serif;"/>　　A:基礎油又分為礦物油和合成油目前市場(chǎng)上看到的大部分都是礦物油為基礎油的潤滑油.而合成油一般用在好點(diǎn)的車(chē)上一方面好點(diǎn)的車(chē)對機油的要求較高一般的機油承受不了另一方面合成油的價(jià)格比較高.那么合成油與礦物油有什么區別呢看看圖就知道了.<br style="font-size: 12px; white-space: normal; background-color: rgb(255, 255, 255); color: rgb(89, 88, 88); font-family: Arial, Helvetica, sans-serif;"/>　　這是一張原油的提煉過(guò)成通過(guò)圖我們可以了解到礦物油的基礎油是原油提煉過(guò) 程中，在分餾出有用的輕物質(zhì)(汽油）之后，剩下來(lái)殘留的塔底油再經(jīng)提煉而成。<br style="font-size: 12px; white-space: normal; background-color: rgb(255, 255, 255); color: rgb(89, 88, 88); font-family: Arial, Helvetica, sans-serif;"/>　　? 本質(zhì)上，它是運用原油中較差的成份，原油中存有幾千個(gè)不同的混合物分子組成，提煉技術(shù)即使再精進(jìn)，亦無(wú)法將其中不良物、雜質(zhì)去除殆盡。<br style="font-size: 12px; white-space: normal; background-color: rgb(255, 255, 255); color: rgb(89, 88, 88); font-family: Arial, Helvetica, sans-serif;"/>　　? 合成油的基礎油，來(lái)自于原油中的瓦斯氣或天然氣所分散出來(lái)的乙烯、丙烯，再經(jīng)聚合、催化等繁復的化學(xué)反應才煉制成大分子組成的基礎液。<br style="font-size: 12px; white-space: normal; background-color: rgb(255, 255, 255); color: rgb(89, 88, 88); font-family: Arial, Helvetica, sans-serif;"/>　　? 本質(zhì)上，它使用的是原油中較好的成份，加以化學(xué)反應并透過(guò)人為的控制下達到預期的分子形態(tài)，其分子排列整齊，抵抗外來(lái)變數的能力自然很強，因此合成油體質(zhì)較好，其對熱穩定、抗氧化反應、抗粘度變化的能力自然要比礦物油強的多。<br style="font-size: 12px; white-space: normal;
