▎ 摘 要
NOVELTY - Super durable heavy-duty anticorrosive coating system of railway steel bridgene zinc based fluorocarbon comprises primer coating, epoxy micaceous iron thick paste intermediate coating and graphene modified fluorocarbon finish coating. The primer coating is flake alcohol soluble inorganic alkene zinc primer coating or epoxy alkene zinc primer coating. The sum of dry film thickness of the scale alcohol soluble inorganic alkene zinc primer coating, epoxy micaceous iron thick paste intermediate coating and graphene modified fluorocarbon finish coating is 140-280 mu m. The sum of the dry film thickness of the epoxy alkene zinc primer coating, epoxy micaceous iron thick paste intermediate coating and graphene modified fluorocarbon finish coating is 170-310 mu m. USE - Super durable heavy-duty anticorrosive coating system of railway steel bridgene zinc based fluorocarbon. ADVANTAGE - The anticorrosive life of coating system can reach 30-50 years.
