An anticorrosive
coating used on the inner wall of a desulfurization and
denitrification device comprises a main paint component A and a curing agent component B. The main paint component A comprises, by weight,
epoxy resin, phenolic resin, nano-
silicon dioxide, diatomite,
ceramic micro-
powder, glass
powder,
carbon black, a dispersing agent, a flatting agent, a defoaming agent,
barium sulfate, an antirust agent, a 1#
solvent,
graphene nano-
platelet powder and
activated carbon. The curing agent component B comprises, by weight, a modified amine hardener and a 2#
solvent. The weight ratio of the component A to the component B is 3.5-4.5:1. The anticorrosive
coating is used for
corrosion prevention of the inner wall of a dust remover of the desulfurization and
denitrification device, is convenient to apply,
corrosion of highly corrosive
flue gas (such as SO<2>, NO<x>, HF and HCl) to the steel inner wall is effectively prevented,
corrosion of highly corrosive liquid (such as H<2>SO<4>, HCl and HF) is effectively prevented, and meanwhile a paint film formed by the anticorrosive
coating has very high abrasion resistance, temperature endurance and cold and hot
shock resistance.
