Análisis del proceso de aplicación de pintura electroestática en polvo para componentes de transformadores y la evaluación de su adherencia y anclaje bajo ambientes controlados

Abstract

Currently, electrostatic powder coatings are gaining more reliability and applicability in the national industry, in the metal-mechanical segment and electrical cabinets. Therefore, in order to determine each one of the controlled environments and their respective specimens, we proceed with this research to determine their resistance to each one of the tests. In the present experimental work, the controlled environments to be used were analyzed for the population of transformer components in which electrostatic powder paint was applied, elaborated under control conditions in which the type of paint, adhesion voltage, surface preparation and curing temperature were addressed. The properties of adhesion, impact, bending and saline chamber were determined according to the standards collected, within which the necessary conditions were stipulated to carry out the pertinent tests. Thus, there were two groups of data, quantifiable and categorically estimable, the first ones were statistically reviewed and the second ones according to what could be observed according to the criteria of the standard used.
