Finally, some good news for tank builders: The tank construction sheet Polystone® CubX® featuring a unique inner cube structure for outstanding stiffness properties. Potential steel reinforcement reductions of up to 100%. The time saving in tank construction is enormous.
"We were able to dispense with steel reinforcement and the associated welding work completely and as a result complete both tanks earlier than originally planned."
Pascal Adam, Production Manager at G&H Kunststofftechnik GmbH & Co. KG, Sprockhövel | Germany. Project: Production of two rinsing water tanks for an anodising plant. Polystone® P CubX® provided the opportunity to produce the tanks faster than rectangular tanks of comparable dimensions made of solid plastic sheets.
As an expert in tank construction, you know: even quite small rectangular tanks for storing chemical media normally require elaborate steel reinforcement. Cladding with plastic profiles, which have to be elaborately cut to size and welded, is required to protect the steel reinforcement against corrosion.
With Polystone® CubX®, Röchling has now developed a completely new tank construction sheet with an inner cube structure that allows for quicker and easier rectangular tank construction.
The special feature is the sheet design, which combines very high longitudinal and transverse stiffness in the sheet itself. Polystone® CubX® consists internally of a homogeneous, rectangular (orthogonal) grid pattern, welded to two sheets on its outsides, which form the sheet surface. The result is an innovative construction sheet that combines light weight and ease of handling with very high longitudinal and transverse rigidity.
The sheet, which was specially developed for tank construction, is also suitable for permanent contact with a large number of chemical media thanks to the proven chemical resistance of Röchling materials. The considerable reduction (up to 100%) of steel reinforcements that would otherwise be required for thermoplastic rectangular tanks also results in significant time savings in tank manufacturing.
Depending on the size of the tank, rectangular tanks made of Polystone® P CubX® require less or even no plastic-coated steel reinforcements due to the high rigidity of the sheet. This significantly reduces the number of necessary welds and saves time and resources.
Tests in our in-house material laboratory show: A Polystone® P CubX® sheet with a thickness of 57 mm has the same stiffness as a solid plastic sheet made of PP with a thickness of 35 mm, but weighs only half as much. This simplifies the handling of the sheets. Also ideal for tank repairs and retrofits.
Polystone® P CubX® increases the process reliability of your rectangular tank when compared to solid plastic sheets. If leakage occurs, the leaking fluid accumulates locally and is limited in the interior of the sheet. The operator thus has more time to take appropriate measures. For leakage monitoring, Polystone® P CubX® sheets are already equipped with a recess as standard, which forms a cavity in the finished tank for interior monitoring, by wire for example. It can also be used as a collecting channel for external optical monitoring.
Polystone® P CubX® offers good thermal insulation thanks to the air trapped in the hollow chambers. Elaborate and costly insulation work can be reduced or saved.
The flame retardant version Polystone® PPs CubX® is especially suitable for sensitive applications with high fire protection requirements.
