A Flame Treating process consists of exposing the surface to a suitable oxidizing flame for a period in the range 0.2 to 3.0 seconds. This treatment brings about a change to the polymer surface that increases its surface energy allowing fluids to effectively wet-out the surface and permits a strong adhesive molecular and mechanical bond.
2019-5-7 · This page describes how to do a flame test for a range of metal ions, and briefly describes how the flame colour arises. Flame tests are used to identify the presence of a relatively small nuer of metal ions in a compound. Not all metal ions give flame colours. For Group 1 compounds, flame tests
