Graphene anti-corrosion and heat dissipation coating is by no means a concept, you don't even know it?
Guangna Nano's research on graphene coatings has never stopped. As a new type of nanomaterial, graphene is an important raw material driving technological innovation in the coatings industry. In 2017, graphene coatings made a major breakthrough and began to be gradually used in various industries, breaking foreign monopoly, and graphene coatings developed rapidly. The application of graphene in coatings The application of graphene in coatings is mainly manifested in heat conduction and heat dissipation in the electronic field, and heavy anti-corrosion treatment in the marine field. The use of graphene's physical barrier properties in coatings can improve the anti-corrosion, anti-fouling, and flame-retardant effects of coatings; using its high electrical conductivity and high thermal conductivity, conductive coatings, heat dissipation coatings, and electromagnetic shielding coatings can be developed. 1. Graphene heavy-duty anti-corrosion On November 23, at the Zhoushan 500 kV networking project site, more than ten staff members were spraying and brushing the neatly stacked iron tower pipes on the ground.“Graphene heavy-duty anti-corrosion coating”, put on an embalming suit for the tallest tower in the world under construction“armor”. For a long time, how to slow down the corrosion of metal objects, prevent surface peeling, and ensure that the internal structure of the equipment is not damaged in the island environment with high humidity and salinity, thereby prolonging the life of the tower, has been an important topic studied by the power supply department in coastal areas. The application of graphene heavy-duty anti-corrosion coatings is undoubtedly a powerful solution to this problem. 2. Graphene heat dissipation Graphene itself has high thermal conductivity and high specific surface area, which can increase the heat dissipation area of the coating. The wide nanometer makes full use of this. The coefficient is increased to 20W/M.K, and the thermal conductivity of the thermal paste is 2W/M.K and the thermal conductivity of the graphene thermal coating is 10 times different. GN-706 graphene high thermal conductivity and heat dissipation coating is used in LED, stage equipment and electronic equipment. Guangnan Nano also made an interesting little experiment, so that more people can witness the heat conduction speed of GN-706 graphene high thermal conductivity heat dissipation coating. In the video, we can see that there is a significant difference in the heat transfer speed between the aluminum plate without graphene coating and the aluminum plate with graphene coating. Moreover, with graphene coating, the heat conduction is more uniform and greatly improved heat dissipation efficiency. Guangna Nano's unique 1. Aviation-grade nano-composite ceramic technology process, the effect is more stable. 2. Unique and mature nano-ceramic dispersion process technology, the dispersion is more uniform and stable; the bonding interface between nano-micro particles is treated efficiently and stably, ensuring better bonding strength between the nano-composite ceramic coating and the substrate, better performance and stability; the formula of nano-composite ceramics is compounded , making the nanocomposite ceramic coating function controllable. 3. Nano-composite ceramic coating, showing good micro-nano structure (nano-composite ceramic particles are well wrapped with micro-composite ceramic particles, and the gaps of micro-composite ceramic particles are filled with nano-composite ceramic particles to form a dense coating. Nano-composite ceramic particles penetrate and fill the repair base. On the surface of the material, it is easier to form a large number of stable nanocomposite ceramics and the intermediate phase of the substrate) to ensure the dense heat conduction and heat dissipation of the coating. Graphene coatings are widely used Nano graphene coatings can be used in heat exchangers, lighting radiators, thermally conductive devices, automotive lights, rectifiers, batteries, computer all-in-ones, display screens, energy storage, Chemical pipelines, boilers, electronic components, electrical products, molds, etc. Graphene has excellent physical barrier properties, high electrical and thermal conductivity, outstanding mechanical properties and chemical stability, making it widely used in the coating industry. At present, graphene has achieved excellent results in anti-corrosion, electrical conductivity, and heat dissipation coating systems. With the application and development of graphene coatings, many problems that could not be solved can be solved one by one, and the performance of many products with low efficiency can be gradually improved.
