BD407 high temperature anti chemical impact corrosion resistant epoxy coatings
used in Yunfu power plant desulfurization absorption tower slurry pipeline ceramic
rubber lining abrasion corrosion repairing and protecting
The end of February 2015,when guangdong yunfu power plant overhaul,found that the corrosion resistant lining of the absorption tower
internal is serious damage,in order to maintaining the power plant running smoothly,decided to do local repairing for the damaged parts,
after that,do a layer of anti wear abrasion corrosion resistant coating for overall.
First clean up the rusting,dirt etc.impurity on the surface of substrates,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 the ideal bonding effect.
2.The preparation of BD407 anti corrosion resistant repair epoxy coating:
Make BD407 anti corrosion resistant epoxy repair 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 BD408 high temperature flakes corrosion resistant repair coating:
After the BD407 anti corrosion resistant repair compound epoxy coatings initial curing,make the BD408 flakes high temperature
anti corrosion resistant 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 BD705 anti abrasion wear resistant epoxy compound repair coating:
After the BD408 flakes high temperature corrosion resistant epoxy coatings initial curing,scrape coating a layer of BD705 wear & corrosion
resistant coatings on its surface.
It can be put into using after complete curing (curing for 24 hours at room temperature)
