問：打開的Apiezon真空潤滑脂的保質(zhì)期是多長時間？
答：Apiezon真空潤滑脂復(fù)雜的化學(xué)結(jié)構(gòu)賦予它們強大的“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?。如果揮發(fā)性蒸氣被吸收，那么潤滑脂將失去其優(yōu)異的蒸氣壓特性，直到這些污染物被脫氣。
這就是我們將潤滑脂包裝在“防蒸汽”鋁管中的原因。由于我們無法控制潤滑脂打開后的使用情況，因此我們無法提供產(chǎn)品打開后的保質(zhì)期。然而，實際上，如果在使用后立即蓋上蓋并且它們不暴露于揮發(fā)物，那么較長的使用壽命應(yīng)該不成問題。
除了吸收揮發(fā)物外，產(chǎn)品很穩(wěn)定，長期來看不會發(fā)生其他變化。Apiezon PFPE 501基于全氟聚醚，因此具有高度惰性，并且比碳?xì)浠衔餄櫥灰孜湛諝庵械恼羝?/span>
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.
