Validação de decapante alcalino para uso em equipamento de limpeza de dispositivos de pintura automotiva

Abstract

The present project was carried out in the automotive painting sector of a car assembly industry in the state of São Paulo. In order to stabilize and assist in the opening of the body moving parts, mechanical devices are used, as these accompany the body during the painting process stages, they receive layers of paint, which are accumulated. To avoid the generation of defects on painted bodies due to faulty devices by excess paint layer, they need to be cleaned regularly. This work sought to validate an alkaline paint stripper to be used in a cleaning equipment of these devices, so this cleaning instead of being carried out externally by a contracted company would be carried out internally in the painting sector. In order to validate the paint stripper it was necessary to certify that it did not interfere with the process in the paint booth, it attended the painting process cleaning needs without causing damage to the devices and that there were no abrupt changes in the concentration of the stripping solution in the course of the cleaning cycles. After the tests, the stripping was approved for use in the equipament.
