Fluoropolymers are macromolecules made up of carbon and fluoride which, due to their properties, tend to be used as non-stick and anticorrosive coatings on a wide range of material. Products in the clothing, graphic, chemical and car industries as well as different metal molds and kitchen utensils need fluoropolymers for their coatings and to improve their features regarding sticking and resisting corrosion.
These kinds of coatings tend to be quite effective due to their characteristics. They resist abrasion, they behave stably at high temperatures and their structure is not affected by most chemical agents. Nevertheless, despite their resistance, they wear away with use like any other kind of material. In order to deal with this issue, the alternative to replacing the whole piece, often times a very expensive solution, is removing the coating, taking out any impurities and taking off any parts that are attached, and recoating it.
Merits - Fluoropolymers - Problem - Materials - Surface
Here is where the merits of fluoropolymers become a problem. Since they are extremely resistant and chemically inert materials, they adhere to a surface and do not come off easily. To deal with this, the Manufacturing Processes Engineering research group at the University of Cordoba has validated a new method to take off these kinds of coatings using a laser technique.
After doing several tests on the...
