Solid lubricants 1: Molybdenum disulfide
(固態潤滑劑1 ：二硫化鉬)
In recent articles we have discussed the nature of oils and how they need to be mixed with additives to prepare them for real-world problems. Even synthetic oils need additives to be cleaner and more stable than raw oil. However, even after the necessary additives, there is still a way to further upgrade your oil: solid additives. Enter the molybdenum additive.
在近期的文章我們有討論到油的特性，以及他們為何需要與添加劑混合去補足它們先天的不足。即使是合成油比原油需要添加劑去維持清潔及穩定。然而，即便使用了”必須性”添加劑，還是有個方式可以更提升你的機油：固態添加劑。
讓我們進入鉬添加劑。
Origin and main benefits (起源與好處)
Molybdenum is classified as a metal in the Periodic Table of the Elements. In its natural form it can be found as molybdenite (also called molybdenum disulphide or MoS2).
在元素周期表中鉬被歸類為金屬。在它的天然形式是以molybdenite輝鉬礦被發現(也就是二硫化鉬或MoS2)。
All forms of Molybdenite have a layered structure, making this mineral an excellent lubricating material. Furthermore, the shear strength of molybdenite increases as the coefficient of friction increases, a property known as superlubricity. Do we need to say more?
所有輝鉬礦的狀態都有層狀排列結構，讓這個礦物成為絕佳的潤滑材質。除此之外，輝鉬礦剪切強度會隨著摩擦係數的增加而提升，也就是一般所知的
superlubricity超級潤滑。這樣還需要我們再多說甚麼嗎?
Molybdenum additive uses (鉬添加劑的使用)
Thanks to its naturally low friction, liquid-molybdenum is widely used as an additive. MoS2 particles, around 1–100 µm in diameter, maintain a high lubricity and stability at engine operating temperatures in extreme and regular conditions.
感謝這個天然的低摩擦係數屬性，液態鉬被廣泛的作為添加劑使用。MoS2粒子直徑大約1–100 µm，不論是在嚴苛或一般狀態的引擎運作溫度下，都可保有高度潤滑及穩定性。
It is commonly added to graphite in order to improve sticking. For that reason, you can see Molybdenum-based oils in critical applications such as aircraft engines because they keep their lubricity even in oil loss cases.
MoS2 is also employed as a catalyst in the petrochemical industry.
去添加石墨以增加黏性很常見。因此，你可以看到含鉬油品使用在嚴苛的狀況下，例如飛機引擎，因為它們必須在連失油的狀況下也要保持潤滑。
MoS2也在石化工業中被做為催化劑所使用。
Molybdenum in Xenum 鉬在Xenum中的應用
In our range of products we have two molybdenum additives. These are Super G and MG Gear, two products that have the aim of reducing friction in two critical friction points: the engine and the gearbox.
在我們系列產品中，我們有兩種鉬添加劑。就是Super G 和 MG Gear，這2支品在兩個關鍵摩擦點：引擎及齒輪箱中去減少摩擦。
In both cases the molybdenum is mixed with carbon graphite, one of our most commonly used solid lubricants. We will talk about that specific lubricant in future articles, so…Stay tuned!
在這些產品中的鉬都含有石墨，是我們最常使用的固態潤滑劑。在往後的文章中，我們會持續討論這些特殊的潤滑劑。所以..敬請期待~
