The application of high temperature impact resistant silicon carbide protective coating
Booster fan,wet desulphurization system blower fan generally is static axial flow fan,its working condition is similar to the original flue,it's mainly the solid particle erosive wear, its solution generally brush a layer of BD427 high temperature anti corrosive coatings on the static blade,and then smear 2mm thickness BD776 high temperature impact resistance silicon carbide coatings before the BD427 without curing.
The flue gas heat exchanger (GGH),is the heat transfer site of boiler flue gas and desulfurization flue gas,corrosion and abrasion exist side by side, the combined protective coatings choose the BD427 high temperature corrosion resistant coating and BD776 high temperature impact resistant silicon carbide coating,this place chooses BD776 not only for the application of its wear resistant performance,but also for its good thermal conductivity,the thermal conductivity is 1.4 W/M K, this composite coating is wear resistant,corrosion resistant and heat conduction.
