The superposed thickness of 100,000 layers of graphene is only one diameter of a hair wire. What effect will it have on coating? A few days ago in Jiangsu Rudong held the "Graphene modified anti-corrosion coating technology report", Jiangsu Daopan Technology Co., Ltd. introduced a world's thinnest graphene heavy anti-corrosion coating, corrosion resistance of up to 3,000 hours, is the United States heavy anti-corrosion coating 3 times.
As we all know, preventing metal corrosion is a global problem. The general method of corrosion protection is to paint the metal and isolate the metal from contact with air and water. This method can only achieve metal corrosion for a short period of time and requires regular maintenance, and has certain limitations.
Graphene is currently the most lightweight, thinnest, highest strength, most conductive and thermally conductive nanoscale new material that can improve the performance of raw materials in many applications. The graphene heavy-duty anticorrosion coating uses graphene's good electrical conductivity and sheet lapping properties to add modified graphene to the anti-corrosion coating system and forms a good conductive network with the zinc powder, thereby achieving a breakthrough in low-zinc Under the conditions, it still has excellent cathodic protection and corrosion protection.
According to Feng Guanping, the founding president of the Shenzhen Tsinghua Research Institute and the founder of the graphene industry in China, the combination of graphene and coatings makes the amount of zinc powder only 1/3 of that of traditional anti-corrosion coatings. The zinc vapor pollution during construction is greatly reduced, and graphene is heavy. Anti-corrosion coating is the thinnest type known in the field of anti-corrosion coatings and meets the requirements for lightweighting of coating materials.
Rudong County has the largest offshore wind farm in Asia. The anti-corrosion coating of wind power towers requires heavy anti-corrosion coating. With the construction of the Jiangsu 10 million kilowatt offshore wind farm, the marine heavy-duty anti-corrosion coating industry is facing huge demand. Feng Guanping said: “Only by opening up the application of graphene coating, the offshore wind power industry will become a sunrise industry that will continue to make a difference.†(Intern Wei Xiaomin reporter Zhang Wei)
