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 ceramic bead particle filling epoxy coating.
Construction process of our BD408 anti chemical anti abrasion corrosion resistant ceramic filled epoxy coatings:
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 corrosion resistant coating undercoat:
Make BD407 anti chemical anti corrosion heat resistant epoxy ceramic particle filled 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 flakes corrosion resistant heat resistant chemical resistant epoxy ceramic coating:
After the BD407 high temperature corrosion resistant epoxy ceramic coatings initial curing,make the BD408 flakes anti heat anti corrosion chemical resistant epoxy 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 anti chemical anti heat wear resistant ceramic filled epoxy coatings:
After the BD408 flakes anti chemical high temperature corrosion resistant epoxy coatings initial curing,scrape coating a layer of BD705 chemical resistant wear resistant corrosion resistant ceramic epoxy coating on its surface.
5.Curing
It can be put into using after complete curing (curing for 24 hours at room temperature)
