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 service life of the original substrate by more than 3 times without changing the properties.
