問：Apiezon真空潤滑脂系列的保質(zhì)期是多久？

答：所有 Apiezon 產(chǎn)品的保質(zhì)期為自制造之日起在環(huán)境溫度（10 至 30°C）下存放，在未開封的原始包裝中的保質(zhì)期是10年。

問：打開的Apiezon真空潤滑脂的保質(zhì)期是什么？

Apiezon潤滑脂的復(fù)雜化學(xué)結(jié)構(gòu)賦予了它們強(qiáng)大的“吸氣”特性，這意味著它們會很容易地吸收空氣中的蒸汽，特別是水和其他烴類化合物。如果吸收了揮發(fā)性蒸汽，那么潤滑脂將失去其出色的蒸汽壓力特性，直到這些污染物被排出。

這就是為什么我們將潤滑脂包裝在‘防蒸汽’的鋁管中。由于我們無法控制打開后的潤滑脂的使用情況，因此無法提供開蓋后產(chǎn)品的保質(zhì)期。然而實際上，如果在使用后立即重新蓋緊鋁管，并且不暴露于揮發(fā)性物質(zhì)中，那么應(yīng)該能夠使用很長時間。

除了吸收揮發(fā)性物質(zhì)外，這些產(chǎn)品在長期來看不會發(fā)生其他變化。Apiezon PFPE 501是基于全氟聚醚的，因此非常惰性，比烴類潤滑脂更不可能吸收空氣中的蒸汽。

Q: What is the shelf life of an opened Apiezon container?

A: The complex chemical structure of Apiezon greases gives them strong ‘gettering’ properties, this means that they will readily absorb airborne vapours particularly water, and other hydrocarbons. If volatile vapours are absorbed then the greases will lose their excellent vapour pressure characteristics until these contaminants have been outgassed.

This is why we pack the greases in ‘vapour-proof’ aluminium tubes. As we have no control over the use of the greases once they have been opened we cannot quote a shelf life for the products after opening. Practically, however, if care is taken in re-capping the tubes immediately after use and they are not exposed to volatiles then a long service life should not be a problem.

Apart from absorption of volatiles the products are stable and no other changes would be anticipated in the long term. Apiezon PFPE 501 is perfluoropolyether-based and hence is highly inert and less likely to absorb airborne vapours than the hydrocarbon greases.
