SX/EW Cells
HJ3’s system of carbon fiber composites can be used to repair large polymer concrete tanks used to process copper.  These high strength composite systems are capable of restoring the tensile strength of the polymer concrete tank walls deteriorating from exposure to electrolyte.  The HJ3 composites also provides chemical protection and have been tested to withstand chemicals ranging from pH 1 to pH 13 in over 20,000 hours of continuous exposures. Specific application of these products to electrolytic cells has become a successful repair for the copper industry. (back to top)

Roof Panel Repair
Corrosion of steel wiring within gypsum roof panels leads to cracking and falling debris from the panels.  HJ3 high strength composite materials are used to strengthen the roof panels and protect those panels from aggressive chemical attack from acids used in the copper process.  HJ3 also utilizes thermoplastic top coats such as polypropylene, to create a chemical resistant and pin-hole free surface.

Support Structures
The R/C columns and beams used to support the SX/EW Cells degrade after continual exposure to electrolyte.  HJ3’s high strength composite systems are used as a cost-effective repair and strengthening system to return these support structures to their original design value.  HJ3’s composite systems utilize thermoplastic top coats such as polypropylene, to create a chemical resistant and pin-hole free surface and protect the columns and beams from further degradation.
