Boron Ultra 12
kills active Dry Rot - history in action
HISTORY- Boron for dry
Over the centuries many attempts
were made to control Dry Rot, which caused devastation in both buildings
and ships, to the extent that the second HMS Queen Charlotte when she
was launched in 1810 and inspected, the timbers of the upper decks were
found to be infected with 'the dry rot'. By 1816 the cost of repairs
for this vessel had exceeded the ship's original construction cost.
Many ships were damaged or even sank because of Dry rot which infected
the poorly seasoned timbers during construction.
Samuel Peyp's Report.
"The greatest part of
these thirty ships (without having yet lookt out of Harbour) were let
to sink in such Distress, through Decays contracted...lye in danger
of sinking at their very Moorings". The planks were "in many
places perish'd to powder" and the ships' sides more disguised
by patching "than has usually been seen upon the coming in of a
Fleet after a Battle". "Their Holds not clear'd or aird, but
(for want of Gratings and opening their Hatches and Scuttles) suffer'd
to heat and moulder, till I have with my own hands gather'd Toadstools
growing in the most considerable of them, as big as my Fists."
Compounds of Boron, known
as Borates, have been mined since the late 1800s (hauled by the famous
"20 Mule Teams" of US Borax) and have been used to control
insect pests, including termites and ants, for over 100 years, but this
discovery came too late to save the great timber warships at the time
of their construction. However, it is ironic that today the few remaining
ships now on exhibition in dry docks and their modern replica cousins
are being protected by Boron based wood treatments. From the Frigate
Unicorn, now on display in Dundee to the new ships produced in wood
by Batavia in The Netherlands, back to HMS Victory in London you will
find a common theme - Boron wood treatments.
By the 1940s borate formulations
were starting to be used to protect wood against Dry Rot. Because they
are water soluble, Borates diffuse into wood using the wood's own moisture
and willingly spread in all directions. Disodium Octaborate Tetrahydrate
became the chosen Boron compound for this job, thoroughly tested by
its main manufacturer, Borax USA.
In the 1970s and 1980's
the range of Boron based treatments expanded to include not only the
Powder form (for Termites and Ants, for example) and the liquid form
(dissolved in water for timber treatment against insects and rots before
installation), but also into the Solid Timbor Rods (for installation
into Railway Sleepers, Telephone and Electricity Transmission Poles
to prevent rot and insect attack under ground) and Gels, for deeper
penetration (when carried at higher concentration in Glycol).
These ranges of Boron based
compounds continue today to give the very best protection against Dry
Rot in buildings and ships.
