Abstract Coconut (cocos nucifera L.) palm wood belongs to the class of perishable timbers which can be used as an alternative wood sources with affective preservation. Preservative treatment of coconut wood can enhance the service life of coconut service life of coconut wood. The objective of this study was to develop appropriate preservative methods to treat sawn coconut wood under the prevailing eco-climatic conditions in Kerala and to evaluate the effect of different factors on the treatability of coconut wood. Wood samples were treated with inorganic (Copper Chrome Boron- CCB and Borax Boric Acid-BBA) and organic preservatives (Cashew Nut Shell (CNS) liquid, need oil and turpentine). Diffusion and pressure treatment were deployed for inorganic preservation and organic preservatives were investigated only through diffusion treatment. Wood samples were air dried to a moisture content of about 50 per cent and total of 354 sampled belonging to high and medium density wood were treated with preservatives.
Diffusion treatment of inorganic preservatives in high and medium density wood showed no significant difference in retention whereas significant difference was observed for penetration percentage. For pressure treatment, retention and penetration were significant in high density wood whereas medium density wood showed only significant retention. A proportionate relation existed between the solution concentrations and the two observations- overall retention and penetration percentage. Relation of diffusion period and retention in high density wood showed no uniform pattern while, an increasing trend was seen in medium density wood. Penetration depth followed an increasing pattern under increasing treatment duration in the two density classes. Among the two treatment methods, pressure treatment performed better than diffusion treatment. Absorption percentage of organic preservatives was non-significant among treatment factors (chemicals and duration), and their interaction in the two density classes.
The study found that sawn coconut wood samples could be effectively treated with preservatives complying with the prescribed retention and penetration percentages as per the different standards and therefore, could be used as a potential substitute for conventional timbers.
