In April 2026, REBO prepared and dispatched a new order of wedge-shaped acid resistant bricks to a returning customer in Algeria. The customer had purchased REBO products on previous occasions and placed another order for acid resistant bricks for its zinc electrolysis operations. Before shipment, the bricks underwent REBO’s factory pre-shipment inspection and third-party testing by SGS. The test results met the specified acceptance requirements, providing additional quality verification before delivery.
Where Does Zinc Electrolysis Equipment Face Corrosion Risks?
Zinc production involves acidic process environments, particularly in areas handling sulfuric acid and acidic electrolyte solutions. Depending on the plant’s process design, several areas may require carefully selected corrosion-resistant linings.
- Pickling and chemical treatment tanks: Acidic solutions can attack unsuitable lining materials and exposed concrete surfaces.
- Circular acid storage tanks and reaction vessels: Curved walls and transitions require a lining design that accommodates the vessel geometry while maintaining consistent joints.
- Electrolyte handling and designated electrolysis-cell areas: Where the equipment design calls for acid proof lining, material compatibility and joint integrity are critical to protecting the underlying structure.
- Drainage channels and collection pits: Acidic spills and process drainage can create localized corrosion risks if the containment system is unsuitable.
Why Wedge-Shaped Acid Resistant Bricks?
For circular tanks, curved vessel walls, and other applications with specific geometric requirements, standard straight bricks may not provide the most suitable fit. REBO wedge-shaped acid resistant bricks are designed to support curved or angled brickwork when the selected shape matches the lining design.
- Better Adaptation to Curved Structures
The wedge geometry helps form the required curvature in circular vessels and other suitably designed structures. - More Controlled Brick Joints
Correctly selected wedge dimensions help maintain a consistent joint arrangement along curved sections. Joint thickness and workmanship must still follow the lining design and installation specifications. - A Protective Barrier Against Acidic Media
When the bricks are compatible with the actual process conditions and installed with suitable acid resistant mortar, the lining helps protect the underlying substrate from corrosive liquids. - Support for Planned Maintenance
A properly designed brick lining system can help reduce corrosion-related deterioration and support more predictable inspection and maintenance planning.
Factory Inspection and SGS Testing Before Shipment
For industrial lining materials, product quality must be verified before the bricks reach the project site. For this Algerian order, REBO completed its factory pre-shipment inspection and arranged third-party SGS testing according to customer’ requirement. The reported results met the specified acceptance requirements. These checks provide buyers with documented information for evaluating REBO products quality against the agreed specifications.
For projects involving wedge-shaped bricks, inspection should also address dimensions, dimensional tolerances, visible defects, and conformity with the ordered brick profile. The exact tests and acceptance criteria depend on the agreed inspection scope.
