The application of desulfuration system slurry shower pipeline anti heat anti impact chemical resistant repair coating:
Slurry shower pipe,its distribution pipe network has two kinds of steel lining rubber pipe and glass fiber reinforced plastic pipes.It will appear the bulge,peeling and falling off etc.phenomenon for the steel lining rubber pipe during using,if it appears for a large area,we should peel off the rubber layer,make the combined protective coatings on the steel pipeline,choose the materials of BD407,BD408 and BD7053.If it is only the partial bulge or peeling, you can clean up the adhesive residue of this part,smear the BD436 rubber lining repair agent to do the repairing.BD436 rubber lining repairing agent both has wear resistant and corrosion resistant performance,at the same time,it has higher bonding strength to metal and rubber,according to the experience data, every 2.5mm thickness BD436 coatings can provide one year's protection for the spray system during repairing.The corrosion resistance of the glass fiber reinforced plastic pipeline is undoubted,when the wear resistant coating on its surface is failure, can smear the BD7053 desulfurization special wear resistant coatings for abrasion resistant protection again.
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.
