TECHNICAL DESCRIPTION OF PRODUCT
The PANACOR AC10 noise barrier panel is specially designed to reduce noise generated by road and rail traffic.
Its design criteria take the noise signature of road and rail traffic as the reference on which to base the panel’s efficient noise abatement performance.
Likewise, the panel’s mechanical behaviour has also been optimised by fitting it with 4 deep intersecting joints that improve its mechanical resistance to strong winds.
COMPOSITION OF THE FENCING PANEL
STRUCTURAL COMPONENTS
TWO-COMPONENT RUBBER SEALS FOR IMPROVED PERFORMANCE
The acoustic panel is designed so that it can house optional rubber seals made of one rigid PVC part and a second part made of flexible EPDM rubber, so that the panel fits the size of the different types of sections used. These seals prevent the fence panels from vibrating due to wind pressure or suction forces caused when trains and vehicles rush past. They also help to prevent any noise leaks in the contact between the panel and the support post. |
SURFACE FINISHES
Anti-corrosion treatment. The heat spray coating process to which PANACOR AC10 acoustic fence panels are subjected produces excellent resistance to the effects of adverse weather, heat or continued exposure to sunlight, by providing enhanced corrosion-resistance and thus a product that requires practically no maintenance.
STAGE 1
PRE-TREATMENT
Automatic process to prepare panels for electrostatic application of paint dust.
Dip 1
Tank capacity: 5600 lt
Dip temperature: 35 to 45oC
Composition of dip liquid: De-greasing agent; passivator; water;
Daily monitoring of concentration levels in pre-treatment dip tank 1 according to specific procedure.

DRYING
All metal parts are placed in a blow drying tunnel at a temperature of between 80 and 100oC to eliminate any moisture prior to the subsequent spray coating stage.STAGE 3
PAINT BOOTH
Automatic process using robots and touch-up guns with spray nozzles that guarantee a perfectly smooth, uniform coat is applied to the panels to ensure an excellent finish.STAGE 4
CURING OVEN
Process in which the paint finish is achieved by applying heat for at least 10 minutes at an average temperature of 200 oC. Oven temperature: 165 to 230oC.
