Metz corrosion and chemical resistant tile and resinous systems are formulated to perform in even the harshest of corrosive environments – providing a protective barrier against chemical attack on concrete, steel or other materials.
Each industry has its own characteristic requirements. When these are assessed along with the clients brief and specific site conditions, Metz are able to tailor the recommended solution to suit. This may be a coating, topping, tile or brick system, however in some cases it makes more sense to utilise a combination of these materials. Whether the corrosive environment is mild or extreme, Metz are able to protect your assets and provide a solution that considers not only a budget but life cycle costs as well.
Typical Metz solutions and systems include:
Acid bricks differ from typical commercial bricks most significantly in their low absorption rates and variety of physical shapes available. Low absorption rates ensure aggressive chemicals do not penetrate the lining system. Special shapes enable complex and sometimes very large vessels to be lined in a manner maximising chemical, thermal and abrasion resistance.
Acid tiles are not only of lower porosity but also commonly much thicker than conventional tiles. This additional thickness contributes to high stability and additional physical protection providing an enhanced depth of matching chemical resistant grout.
Metz manufactures a broad range of corrosion resistant fixing materials to complement these acid resistant ceramics. This means a complete acid proof ceramic lining system from a single source is possible for our clients.
Metz chemical resistant coatings are used in corrosive environments where our clients wish to prevent attack of generally steel and concrete by extremely strong chemicals. Coatings are economical, highly chemical resistant layers usually of 100–300 microns per coat. Reinforcement or localised thickening is possible for areas experiencing heavy physical impacts, high abrasion or high thermal shock.
Acid resistant linings and toppings are heavier-duty systems than coatings. Linings are approx. 1–2 mm thick systems, toppings are normally 2–8 mm in thickness. Linings and toppings are more suitable than thinner coatings for repair of acid attacked concrete, for example when there is the need to replace cm, rather than mm of areas removed by highly corrosive chemicals. These materials may be either poured, sprayed or trowelled into place.
Metz manufacture a range of acid resistant concretes to resist the strongest chemicals in extremely demanding physical environments. Materials exist that require no further protective layers after placement, so ideal for shutdown rectification of badly chemical attacked areas. Alternatively for new projects the enhanced physical protection a thick concrete lining can provide is essential for long term performance.
In addition to the abovementioned materials a range of membranes, movement joints, anchors, waterstops and other associated materials are necessary to ensure Metz can offer our clients a complete acid and alkali resistant lining solution for almost any conditions.
