不粘涂料的起源

Nonstick coatings hit the selling floors in the early 1960s.

The first nonsticks were made primarily of polytetrafluoroethylene (PTFE). PTFE has the lowest coefficient of friction (CoF) of any known solid. In other words, the majority of materials (in this case foodstuffs) do not stick to it.

PTFE's low CoF "releases" the materials, making it easy to separate them from the coating. Therefore, on nonstick pans, most substances are easily removed from the surface.

Unfortunately, PTFE is also very soft and, if unprotected, wears quickly. While early nonsticks had good release, they were soft and wore out after little use. The result: nonstick-coated cookware earned the reputation of being "disposable".

防范胜于治疗

最终确保含氟聚合物涂料性能的是固化。固化过程:硬化涂料,使其光滑,并建立耐化学性。可以通过熔体流动或聚合物基体的交联来实现。(“交联”是把大部分的化学品链接起来,交联前后的区别是,它 是一组线松松地集结在一起,而是一个共同的线缝制成的布。)

然而,这些特性的实现需要涂层正确的完成固化,涂料制造商所提供的产品规格书,会提供涂层是如何被烧结的具体细节,这个过程中有五个参素必须进行监测,以保证完美的烧结。
