問：Apiezon真空潤滑(hua)脂系列(lie)的保質期是(shi)多久？

答：所有(you) Apiezon 產品的(de)保質期為自制造之(zhi)日起在環境(jing)溫(wen)度（10 至 30°C）下存(cun)放，在未(wei)開封的(de)原(yuan)始包裝(zhuang)中的(de)保質期是10年。

問：打開的(de)Apiezon真空潤滑脂的(de)保質期(qi)是什么？

Apiezon潤滑(hua)脂的(de)復雜化(hua)學結構賦(fu)予了(le)它(ta)們強大的(de)“吸(xi)氣(qi)”特(te)(te)性(xing)，這意味(wei)著它(ta)們會很容易地(di)吸(xi)收空氣(qi)中的(de)蒸汽(qi)，特(te)(te)別是(shi)水和(he)其他烴(jing)類化(hua)合物。如果吸(xi)收了(le)揮(hui)發性(xing)蒸汽(qi)，那么潤滑(hua)脂將失去其出色的(de)蒸汽(qi)壓力特(te)(te)性(xing)，直到這些(xie)污染物被排出。

這(zhe)就是為什么我們(men)將(jiang)潤滑脂(zhi)包裝在(zai)‘防蒸汽’的鋁管中(zhong)。由于我們(men)無(wu)(wu)法(fa)控(kong)制打(da)開后的潤滑脂(zhi)的使(shi)(shi)用情況，因(yin)此無(wu)(wu)法(fa)提供開蓋后產品(pin)的保質期。然而(er)實(shi)際上，如(ru)果(guo)在(zai)使(shi)(shi)用后立即重新蓋緊(jin)鋁管，并且不暴露于揮(hui)發性物質中(zhong)，那(nei)么應(ying)該能夠使(shi)(shi)用很長時間(jian)。

除了吸收(shou)揮發(fa)性(xing)物(wu)質外，這些產(chan)品在(zai)長期來看不會(hui)發(fa)生其他變化。Apiezon PFPE 501是基于全氟聚醚的，因此非常惰(duo)性(xing)，比烴類(lei)潤滑脂更不可能吸收(shou)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.
