Abstract
A detailed study on arsenical creosote with reference to
leaching, corrosion and anti-borer properties was carried out.
Results showed that aging had very little effect on the preservative
which suggested better fixation of the preservative into the wood.
Corrosion of mild steel, galvanised iron, aluminium-magnesium
alloy (M57S) and copper panels in the preservative was found to
be negligible, Normal creosote and low temperature creosote of
Regional Research Laboratory, Hyderabad, both fortified with
arsenic trioxide resisted borer damage on wooden panels for a
period of over five months in the port of Cochin. The performance
of low temperature creosote fortified with arsenic was found
to be equally satisfactory when compared to normal creosote fortified
in the same manner A loading of 208.6 Kgs/m3 for Haldu
(Adina cordifolia) and 138 Kgs/m3 for Mango (Mangifera indica)
in the case of normal creosote and 177 Kgs/m3 for Mango in the
case of RRL creosote were found to be sufficient for treating
the wood.
