Avaliação do pré-tratamento com nanocerâmico em substituição ao fosfato de ferro utilizado em linha de pintura eletrolítica

Abstract

One of the major problems encountered in the modern world is oxidation. Much is done in the corporate world to minimize or eliminate the existence of this problem. In addition to this factor, in recent years, competitiveness between companies has been gradually intensified. The dispute for competitive advantages, be it either in processes or inputs, it becomes a determining factor for the survival of these companies in such a competitive market. The study consists of analyzing and comparing the application of the pre-treatment bath of a powder coating line that currently uses iron phosphate plus degreaser, compared to the nano ceramic compound (Bonderite CC-42). Bonderite CC42 is a liquid surface treatment product, produces conversion layers that provide excellent corrosion resistance and an excellent anchor base for liquid, powder or electrophoretic paints. The replacement of iron phosphate for nano ceramic aims the elimination of phosphorus in the effluents, thus improving the fluid generated for the environment. The present work meets the strategic objective of reducing energy in the paint pre-treatment line by eliminating one of the current bath tank stages. The proposed process was validated in accordance with the normative tests of the following ISO's (ISO 9227 - Salt spray, ISO 1519 - Cylindrical bending of mandrel, ISO 2409 - Adhesion to surface, ISO 6272 - Impact resistance). The new product was approved with good performance. This resulted in annual gains such as decrease in water consumption of 198,000 liters (33.33%) and a decrease in electricity consumption of more than R$ 72,000.00 (seventy-two thousand reais). The total annual gain with the use of Bonderite CC 42 was approximately R$ 250,000.00 (two hundred and fifty thousand reais). [resumo fornecido pelo autor]
