Apiezon L  Grease 超高真空潤滑油脂特性

--不會出現(xiàn)與硅基潤滑脂相關(guān)的污染問題，例如“蠕變”或“殘留”

--提供很好的潤滑性能

--建議在環(huán)境溫度下使用

--具有內(nèi)置的抗輻射能力

--具有強(qiáng)大的“吸氣”作用，這意味著它可以吸收金屬和玻璃表面上潛在有害的油脂和化學(xué)雜質(zhì)

--由于可溶于碳?xì)浠衔锶軇虼艘子谇鍧嵑腿コ?/span>

作為一種超高真空潤滑脂，具有優(yōu)異的潤滑性能和抗輻射性，Apiezon L 潤滑脂可用于多種不同的應(yīng)用。特別是L 潤滑脂常用于科學(xué)和工業(yè)密封和潤滑應(yīng)用。

Apiezon L  Grease 潤滑脂經(jīng)過專門配制，可提供很好的潤滑性能，同時(shí)保持高效的氣密封，因此廣泛用于高性能真空泵的制造和維修。

使用不含硅的 Apiezon L  Grease 潤滑脂可避免經(jīng)常導(dǎo)致樣品污染的“蠕變”和“殘留”問題。因此，它經(jīng)常用于避免樣品污染的分析技術(shù)，例如紅外或質(zhì)譜分析。

同樣，“蠕變”可能會在工業(yè)油漆或金屬沉積過程中引起問題，因?yàn)楸砻嫔系奈⒘坑袡C(jī)硅會阻礙油漆的粘附，導(dǎo)致覆蓋效果差。使用不含硅的Apiezon L  Grease 潤滑脂時(shí)，這不是問題。

作為一種無鹵產(chǎn)品，Apiezon L  Grease 潤滑脂具有內(nèi)在的抗輻射能力。其他高真空潤滑脂，例如酯類、有機(jī)硅或鹵化石蠟，在 0.1 MGy 或更低的輻射水平下會分解。相比之下，L 潤滑脂在高輻射應(yīng)用中保持優(yōu)異的潤滑性能，當(dāng)用 4 MeV 電子照射到 1 MGy 時(shí)，剛度僅略有增加。

常見問題

問：如何清除 Apiezon 碳?xì)浠衔餄櫥?/span>

答：可使用柔軟、潔凈的無棉絨布輕松擦除Apiezon烴基潤滑脂。任何殘留潤滑油都可用溫肥皂水及所有芳香烴溶液（甲苯、二甲苯）洗去。

問：Apiezon 潤滑脂在熔點(diǎn)以上會發(fā)生什么情況？

答：所有潤滑脂（除了 Apiezon H 潤滑脂）都會液化，但在冷卻后會恢復(fù)到正常狀態(tài)和性能，前提是溫升不過分。 

問：打開的 Apiezon真空潤滑脂的保質(zhì)期是多久？

答：Apiezon 復(fù)雜的化學(xué)結(jié)構(gòu)賦予它們強(qiáng)大的“吸雜”特性，這意味著它們很容易吸收空氣中的蒸氣，特別是水和其他碳?xì)浠衔铩Ｈ绻麚]發(fā)性蒸氣被吸收，那么真空脂將失去其優(yōu)異的蒸氣壓特性，直到這些污染物被脫氣。這就是我們將真空脂包裝在“防蒸汽”鋁管中的原因。由于沒辦法控制真空脂打開后的使用情況，因此無法提供產(chǎn)品打開后的保質(zhì)期。然而，實(shí)際上，如果在使用后立即重新蓋上管子，那么使用壽命會很長

問：Apiezon 潤滑脂是否抗輻射？

答：Apiezon L 和 M 潤滑脂表現(xiàn)出一定程度的耐輻射性，在用 4 MeV 電子照射至約 1 MGy 水平后，剛度僅相對較小地增加。在此暴露之后，潤滑脂的潤滑性能仍然令人滿意，并且在更高水平的輻照下也是如此，盡管剛度增加得更快。

在高水平的照射下，會產(chǎn)生少量氣體（主要是甲烷和乙烯），從而使?jié)櫥テ錁O低蒸氣壓的特性。盡管如此，與其他高真空潤滑劑（例如硅樹脂、酯類和鹵化產(chǎn)品）相比，Apiezon 潤滑脂 L 和 M 在高輻照水平下是明顯更好的潤滑劑。

What is Apiezon L grease?

Apiezon L Grease is a silicone and halogen-free ultra-high vacuum grease suitable for use scientific and industrial applications.

Apiezon L Grease has the best vapour pressure properties of all the Apiezon products and is therefore suitable for use in ultra-high vacuum applications. L Grease is regularly used by highly respected organisations such as The European Space Agency, NASA and NATO.

Apiezon L Grease is designed for use at ambient temperatures (generally between 10 to 30°C / 50 to 86°F). If you are looking for a grease capable of performing at higher temperatures, Apiezon AP101 or Apiezon H Grease may be more appropriate.

What are the properties of Apiezon L grease?

Apiezon L Grease is a silicone and halogen-free ultra-high vacuum grease which:

-exhibits an extremely low vapour pressure of 7 x 10-11 Torr at 20°C

-does not suffer from contamination problems associated with silicone based greases such as ‘creep’ or ‘carry over’

-provides excellent lubrication

-is recommended for use at ambient temperatures

-has built-in radiation resistance

-has powerful ‘gettering’ action, meaning it absorbs potentially harmful grease and chemical impurities on metal and glass surfaces

-is easy to clean and remove as it is soluble in hydrocarbon solvents

-Available to buy in 25g or 50g tubes.

When should Apiezon L grease be used?

As an ultra-high vacuum grease with excellent lubrication properties and radiation resistance Apiezon L Grease is used for many diverse applications. In particular, L Grease is commonly used in scientific and industrial sealing and lubrication applications.

Apiezon L Grease has been especially formulated to provide excellent lubrication while maintaining an efficient gas seal and is therefore widely used in the manufacture and servicing of high performance vacuum pumps.

Using silicone-free Apiezon L Grease avoids the problems of ‘creep’ and ‘carry over’ which can often lead to sample contamination. Therefore, it is regularly used in analytical techniques such as infrared or mass spectrometry where sample contamination must be avoided.

Similarly, ‘creep’ can cause problems in industrial paint or metal deposition processes as trace amounts of silicone on surfaces can prevent the adherence of paint, leading to poor coverage. When using silicone-free Apiezon L Grease this is not a problem.

As a halogen-free product Apiezon L Grease has a built-in resistance to irradiation. Other high vacuum greases such as esters, silicones or halogenated paraffins decompose at radiation levels of 0.1 MGy or less. In contrast, L Grease maintains excellent lubrication properties in high radiation applications, demonstrating only a small increase in stiffness when irradiated with 4 MeV electrons to 1 MGy.
