Effect of weathering on wood treated with tall oil combined with some additives

摘要: Growing interest on bio-based material has led to focus environmentally benign wood treatment systems because of the environmental concerns. Tall oil is a by-product from pulp and paper industry, contains resin fatty acids, biodegradable. treated can provide some reduction in water uptake increase decay resistance. In this research crude tall was dissolved ethanol at 5, 10 15 % concentrations Scots pine according full cell process. Dyestuff, iron oxide sodium ascorbate were used an additive as 0,5 %. Weathering performance combined with additives investigated accelerated weathering chamber by application ultraviolet irradiation spray. It taken for granted that increasing concentration results higher weight percent gain samples. The best obtained which indicated minimum total color changes. Colour measurements visual examination revealed most effective reducing effect lowering colour change.
