The application of BD7053 absorption tower anti impact anti abrasion chemical resistant repair coatings:
Absorption tower,absorption tower is the core equipment of wet desulfurization (FGD) system,made of the tower body,support beam,lattice beam,bracket,tray etc.The flue gas contacts and mixes with the slurry here to finish desulfurization reaction.This area is mainly the corrosion together with abrasion.The combined protective coatings choose the BD407 corrosion resistant coating,BD408 flake coatings and BD7053 desulfurization special abrasion resistant coating,to achieve the combined coating structure of the outer abrasion resistance and inner corrosion resistance.It has the wear resistant layer to protect the anti corrosive coatings from causing failure by the erosive wear, to provide continuous protection for the workpiece,the lifetime of the whole coatings depends on the thickness of surface abrasion resistant layers.According to the empirical data,the BD7053 desulfurization special wear resistant coatings applied to the absorption tower internal,every 1.3mm thickness can provide the protection for the absorption tower about 1 year.
The flue gas damper door,it's mainly corrosion based on the place where contacts with the net flue gas,together with the abrasion,the combined coatings choose BD407 corrosion resistant special coating,BD408 high temperature flakes anti corrosion wear resistant coatings,BD7053 desulfurization absorption tower and slurry pipeline special anti corrosion abrasion resistant coating.It's mainly the abrasion based on the place where contacts with the original flue gas,the combined coating chooses BD427 high temperature corrosion resistant coatings and BD776 high temperature impact resistant silicon carbide coatings.
