Abstract

The purpose of this research is to change the microstructure of wood using ultrasonic processing, increase the connectivity between pores in the cell to improve the permeability of the wood, ultrasonic cavitation dye in the wood veneer by the instinstantaneous temperature, high pressure, high jet role in the infection rate has been markedly improved. In the same time under the conditions of the veneer Ultrasonic assisted dyeing dye than conventional high temperature dip. Veneer dyeing dye uptake an yeing rate increases with the enhancement of ultrasonic vibration time increases with the increase of dye concentration increased with the improvement of the dyeing temperature increase. With solid mu fu joins a floor board and furniture industry on dyeing timber demand increases, more than 3 mm thickness of the single homogeneous dyeing problem due to the increasingly prominent in wood for dye solution to move or penetrating horizontal channel is few, the greater the thickness of wood dyeing the more difficult to dye penetration of wood dyeing essence is dye in wood of infiltration and fixed with two process, if the wood permeability good, dye in sessile former is easy to reach inside and outside a uniform color. Dye penetration performance depends on the types of wood and its state dye molecular size and physical and chemical properties of medium physical and chemical properties and dyeing external conditions. Wood dyeing process is dye solution in wood surface wetting diffusion adsorption, and dye solution to wood internal penetration and fixation process. The lumber size is big, dye molecules in the wood mobile and penetration depth is the key to real wood dyeing. This study adopts ultrasonic auxiliary dyeing is the use of ultrasonic cavitation to change the wood conventional dyeing auxiliary dyeing to achieve the purpose of the article.
