Chromatic variation of blue color on European construction timbers by surface application with acids = Variación cromática del color azul en maderas de construcción europeas para la aplicación superficial con ácidos

Abstract

The chromatic variation of the surface of construction timber, by means of the controlled surface application of colorless acids in liquid state allows to establish a predictive model between timbers tested and not tested in this research.The predictive model obtained is based on an abacus, ordered by acids, timbers and blue color (because is the color with the greatest percentage of surface chromatic variation compared to red or green colors), which allows to predict the behavior of the percentage of surface chromatic variation of timbers and acids not tested in this research, comparing them according to their classification, density, species, origin, color, strength and division with seven European construction timbers and fifteen acids that have been tested. The methodology used defines the parameters of choice of the materials chosen and the method of production of chromatic variation of construction timbers, presenting and ordering the results of variation of the blue color obtained in a table.
