選擇合適的真空潤滑脂時需要考慮什么？
選擇合適的真空潤滑脂時需要考慮什么？
1、確保您選擇了可在您的真空條件下工作的潤滑脂。
2、如果潤滑脂變得太熱，它們會熔化或熱分解。如果密封變成液體或遠(yuǎn)離應(yīng)用部位，這將影響密封。如果您的應(yīng)用可能會變熱，請確保您使用的是 Apiezon H 潤滑脂或 PFPE 501 等專為高溫使用而設(shè)計的產(chǎn)品。
3、在低溫下，大多數(shù)潤滑脂會開始開裂。這些裂紋可能是微觀的（龜裂）。如果您使用潤滑脂作為傳熱劑，則裂紋會影響導(dǎo)熱性。確保使用的潤滑脂設(shè)計用于低溫操作（如果需要）。
What do you need to think about when choosing the right vacuum grease?
- Make sure you have picked a grease that will work under your vacuum conditions.
- Greases can melt or thermally decompose if they get too hot. This will affect the seal if it becomes liquid or moves away from the site of application. If your application could get hot, ensure you are using a product such as Apiezon H grease or PFPE 501 which are designed for use at high temperatures.
- At low temperatures most greases will begin to crack. These cracks can be microscopic (crazing). If you are using the grease as a heat transfer agent then cracks will affect the thermal conductivity. Make sure the grease you use is designed for low temperature operation if required.
