Design
 1.
The Membrane
The F130BD design is produced by extruding,
thermoforming, and welding two films
of PANACEA F130 fluoroplastic together, trapping
air in multiple encapsulated cylinders.
The air provides great buoyancy. Specific
gravity of F130BD is approximately .05, and
the manufactured widths of F130BD are
48".
These
widths can be welded together side to side
to achieve widths of any desired measurement.
Lengths of PANACEA F130BD can be processed
to any manageable and shippable dimension.
The covers, including sizes of 50 ft.' or
60 ft.. in diameter are easily fabricated.
The
membrane design incorporates small holes in
the cover (1/8" dia. @ 12"
c/c) allowing for drainage of liquid on top
of the cover and elimination of any
large gas bubbles from under the cover.
2.
Circumferential Stiffening Hoop
The PANACEA F130BD material requires a
"stiffening hoop" to maintain its
shape in a CLO2 storage tank. The stiffening
hoop is constructed of individual rigid P-72
pipe segments The segments are thermoformed
to the required radius and capped both
ends for flotation. The segments are then
joined n the tank with easy-to-assemble
P-72 couplings and to the cover with a P-72
quick connect system.
3.
Repair
Sections of the "PANACEA" F130BD
cover, if damaged , can be cut and replaced
with "PANACEA" F130 film, PANACEA
F130BD, and mechanical plastic or titanium
fasteners with hand tools. No special equipment
is required.
