Comportamento da cor de laminas de madeira de Pau-marfim (Balfourodendron riedelianum) tratada com produtos de acabamento

摘要

This study tested products to combat aging of wood. Through an aging chamber and a spectrocolorimetry device, the influence of chemical finishing products applied to wood were characterized during artificial photodegradation process. The aging of Balfourodendron riedelianum was monitored through 8.807 colorimetry measurements, with the samples undergoing cycles of ultraviolet radiation for periods of: 20, 40, 60, 80, 120, 180, 250, 310, 410 and 500 hours. The data was loaded to Excel and processed. The CIE La*b* system of 1976 showed the color changes. The use of a sealant caused a greater variation in the wood's colorimetric parameters when compared to other treatment methods.
