Abstract

Rubber wood squares of 2, 3 and 5 cm cross-sections were treated with boron compounds (boric acid and borax) by diffusion process. The effect of immersion time on the dry salt retention was studied. The dry salt retention increased with increase in immersion time, although rate of increase was low. For higher thicknesses, prolonged immersion time reduced the dry salt retention. From the relationship of concentration of solution, loading of chemicals, thickness of wood and immersion time, a constant of proportionality was arrived at for rubber wood
