Recently, a graphene 'three-proof' coating technology for preventing high temperature and high humidity, preventing salt spray corrosion and preventing mold has been successfully developed in Hebei Qinhuangdao Economic and Technological Development Zone. It is understood that this coating technology is heavy salt in the South China Sea and the East China Sea. The test of the pendant on the high-temperature parts of the ship in the fog area passed the 6000-hour continuous work verification, which increased the life of the original substrate by more than 3 times without changing the properties. The picture shows the technicians take a comparison on July 15th. The experiment shows the high temperature resistance of the graphene coating: The aluminum plate on the right side is coated with a graphene coating and is not burned by the flame; the left aluminum plate is not coated with a graphene coating and is burned by the flame.
