Ester oil (酯類)
Ester oil is a synthetic lubricant. In the formulations of synthetic oils are commonly used 3 kinds of synthetic base oils:
酯類是合成潤滑油。在合成油的配方中常使用的3種合成基礎油是：
- POLY ALPHA OLEFINS (PAO): The most popular and widely used (ingredient?) in synthetic and semi synthetic oils. PAO have a very good resistance to high temperatures and low volatility.
聚烯α-烯烴 (PAO)：最常見並且廣泛使用在合成及半合成機油(原料?)中。PAO十分耐高溫並揮發性低。
- HYDRO CRACKED BASE (HC): Is not really synthetic product, but a mineral oil that was hydro treated in order to obtain synthetic ‘performance’. HC is a good lubricant but has higher volatility than PAO.
加氫裂解基礎油 (HC)：並不是真正的合成油產品，但礦物油可以用加氫方式好讓它具備合成”效能”。HC的潤滑性不錯，但揮發性比PAO高。
- ESTER OILS: They have been used in lubrication for over 60 years as the favourite base oil in many severe applications. Their properties solve problems and ensure substantial improvement for lubricating products.
酯類基礎油：被使用在潤滑部份超過了60年，很喜歡被使用在許多嚴苛的應用上。它們的特性能解決問題並能大大的提升潤滑油產品品質。
In automotive applications, the first synthetic engine oils, were in fact based entirely on ester formulations and these products were quite successful.
在汽車應用上，第一個合成引擎機油事實上是完全使用酯類配方，這些產品也相當成功。

POLAR MOLECULES(極性分子)
Ester molecules are medium to very polar. This means they possess an electrostatic charge as a result of the opposing charges. Polarity of oil, comes with certain interesting properties:
酯類分子具有中等到高度的極性(吸附性)。這表示由於負電荷而使它們具備靜電荷。有極性的油，有幾個有趣的特性：
• LUBRICITY (潤滑性)
Polarity causes the ester molecules to be attracted to positively charged metal surfaces. As a result, the molecules line up on the metal surface creating a tough film with enhanced adhesion properties.
極性會讓酯類分子吸引金屬表面的正電荷。因此，分子會排列在金屬表面創造出堅固的油膜能強化黏附特性。
That translates into a strong and persistent film providing superior lubricity, lower energy (fuel) consumption and reduced wear.
這表示一個強大且堅固的油膜提供了卓越的潤滑性、低燃油消耗並減少磨損。
• VOLATILY(揮發)
The polarity of the ester molecules makes them to be attracted to one another. This intermolecular attraction requires more energy (heat) for the esters to shift from a liquid to a gaseous state (evaporation). As a result, the oil will keep longer its viscosity and quality. In addition, oil consumption by evaporation will be reduced.
有極性的酯類分子會讓他們彼此間更容易吸附。這種分子內在吸引需要大量的能量(熱)才能讓酯類從液態轉換為氣體(蒸氣)狀態。因此，機油能較長久的持續維持它的黏度及品質。此外，機油因為蒸發而損耗的狀況也會降低。
• DETERGENCY AND DISPERSENCY (清潔及分散)
The polar character of esters also makes them good solvents and dispersants. This allows the esters to solubilise and disperse impurities such as combustion residues and oil degradation, by-products that might otherwise dispose as sludge or varnish deposits. These properties result into cleaner operation and improved additive solubility in the final lubricant.
Cleaner engine or transmission systems will be the consequence.
酯類的極性特質也讓它們具有好的分解力及分散力。這讓酯類能溶解並分散髒污，例如燃燒的殘餘物及機油的質變物，不然，這些產物可能沉積成為油泥或清漆。這些特性會帶來清潔的效果及改善添加劑最後在潤滑油中可溶性。
能夠持續清潔引擎及變速箱系統。
