100,000 layers of graphene superimposed thickness is only the diameter of a hair wire, it is used in
coating
how will it work? Recently held in Rudong, Jiangsu Province, "graphene modified
anti-corrosion coatings
technical report meeting", Jiangsu Daupong Technology Co., Ltd. launched one of the world's thinnest graphene
heavy anti-corrosion coatings
, corrosion resistance reached 3000 hours, is the United States heavy anti-corrosion coatings 3 times.
, preventing metal corrosion is a global challenge. General anti-corrosion method is to paint the metal, insecur the metal and air and water contact, this method can only achieve a short period of time the metal is not corroded, need regular maintenance, and have certain limitations.
graphene is the lightest, thinnest, strongest, conductive and thermally best nanoscale new material ever found, improving the performance of raw materials in many applications. Graphene heavy anti-corrosion coating is the use of graphene good conductivity and chip-like joining characteristics, modified graphene added to the anti-corrosion coating system, and zinc powder to form a good conductive network, thus breakthrough in the low zinc conditions still have excellent cathode protection and corrosion resistance.
According to Feng Guanping, founding director of Shenzhen Tsinghua Research Institute and founder of China's graphene industry, the combination of graphene and coatings makes zinc powder only 1/3 of the amount of traditional anti-corrosion coatings, zinc vapor pollution during construction is greatly reduced, while graphene heavy anti-corrosion coatings are known in the field of anti-corrosion coatings, one of the thinnest known, to meet the requirements of lightweight coating materials.
Such as Dong County has Asia's largest offshore wind farm, wind tower anti-corrosion needs heavy anti-corrosion coatings, with the construction of 10 million kilowatts of offshore wind farms in Jiangsu, the marine heavy anti-corrosion coatings industry is facing huge demand. Feng Guanping said: "Only through the graphene coating application link, the offshore wind power industry will become a long-lasting power of the sunrise industry." "
