BD407 high temperature anti chemical corrosion resistant epoxy coatings used in
power plant desulfurization system concentric reducer ceramic rubber lining repairing and protecting
At the end of Oct.2014,when the state-owned investment Inner Mongolia Daban power plant is overhauling,find that the desulfurization
system concentric reducer inner rubber lining is badly broken,in order to maintaining the power plant smooth running,they decide to do
the partial restoration for the damaged parts first,then make a layer of wear & corrosion resistant coating.
1.Surface treatment: Clean up the rusting,dirt etc.impurity on the surface of substrates first,then do the sand blasting,polishing etc.
roughing treatment.Clean it by cleaning agent and dry it by the airing,make the construction part be clean,dry and no dirty,
reach to ideal bonding effect.
2.The preparation of anti corrosion resistant coating undercoat:
Make the BD407 high temperature anti chemical corrosion resistant coatings mix uniformly according to the mass ratio A:B=4:1,
smear it on the surface of the pending-repair substrates.
3.The preparation of high temperature flakes anti corrosion resistant coating:
After the BD407 anti corrosion chemical resistant epoxy coating initial curing,make the BD408 flakes anti corrosion resistant repair coating
mix uniformly according to the mass ratio A:B=4:1,and be coating on the surface of BD407 adhesive layer,the adhesive layers should be
compacted along one direction,avoid appearing the holes
4.The preparation of wear resistant coating:
After the BD408 high temperature flakes anti corrosion resistant epoxy coating initial curing,scrape coating a layer of BD705
anti wear abrasion corrosion resistant epoxy repair coatings on its surface.
It can be put into using after complete curing (curing for 24 hours at room temperature)
