變速箱油在使用過一段之后會進行更換，然而很多用戶會發現，油內部出現了沉淀，那么這種情況下變速箱油有沉淀是因為質量不好嗎？下面來分析分析。

　　The gearbox professional oil will be replaced after a period of use, but many users will find that there is precipitation in the professional oil, so in this case, is the precipitation of the gearbox professional oil due to the poor quality? Let's analyze it.

　　其實，這是一種叫做添加劑析出現象，潤滑油中的添加劑必不可少，有些情況下添加劑會發生析出，屬于正常現象，比如低溫時，有些油的少量沉淀就是添加劑的析出，不影響產品正常的使用，屬于正常現象。

　　In fact, this is a phenomenon called additive precipitation. Additives in lubricating oil are indispensable. In some cases, additives will precipitate, which is a normal phenomenon.

　　添加劑析出和沉淀現象和包裝桶的顏色也有密切關系，例如采取深色桶包裝的油產品就不太容易被發現添加析出和沉淀現象，而那些采用顏色較淺的油包裝則看起來更加明顯，還有就是和儲存時間有關，超過半年或一年的儲存的油產品出現析出的可能性更大。

　　Additives precipitation and precipitation phenomenon and the color also has a close relationship between the drum, for example, take the dark professional oil barrels packaging product is less likely to be found to add precipitation and precipitation phenomenon, while those with color shallow professional oil packing looks more obvious, and associated and storage time, more than half a year or a year of professional oil storage product separation are more likely to appear.

　　濟南變速箱油中除了添加劑，就是基礎油，而且占據的比例很高，基礎油關系到油的質量，提供了潤滑油基礎的潤滑，冷卻，抗氧化，抗腐蝕等性能，許多地方由于氣候寒冷，所以十分重視油品的低溫性能，那么相應的基礎油質量就須要好。

　　Jinan gearbox additives professional oil, in addition, it is base oil, and occupy a high proportion, oil base oil is related to the professional quality, provides the basis of a lubricating oil lubrication, cooling, oxidation resistance, corrosion resistance, such as performance, many places because of the cold weather, so attached great importance to oil low temperature performance, then the corresponding need to good quality of base oil.

　　在高檔潤滑油生產中，加氫基礎油具有良好的粘溫性能，抗氧化添加劑的感受性，用量越來越大，加氫基礎油的使用促進了潤滑油質量的提高，但也存在對添加劑溶解性較小的特點。

　　In the production of high-grade lubricating oil, hydrotreating base oil has good viscosivity and temperature performance, anti-oxidation additive sensitivity, and more and more dosage. The use of hydrotreating base oil promotes the improvement of lubricating oil quality, but also has the characteristics of low solubility of additives.

　　因此，其添加劑必然會存在一定的析出現象，這種沉淀是高質量油品所存在的正常現象，高檔潤滑油的沉淀并不需要大驚小怪，均勻搖晃后再進行使用即可，只要在油保質期內就無須擔心。

　　Therefore, the additives are bound to have a certain precipitation phenomenon, this precipitation is the normal phenomenon of high-quality oil, high-grade lubricating oil precipitation does not need to make a fuss, uniform shaking can be used, as long as there is no need to worry about in the shelf life of professional oil.

　　變速箱油有沉淀是因為質量不好嗎？所以說并不是這樣的，是因為添加劑的緣故。所以平常使用中還是要多多去了解相關的內容才行，相關資訊您可以來我們網站www.ihudie.cn看看。

　　Is the precipitation of gearbox professional oil due to poor quality? So it's not that, it's the additives. So in ordinary use or to learn more about the relevant content, you can come to our website www.ihudie.cn to see the relevant information.
