Graphene anti-corrosion and heat dissipation coating is by no means a concept, you don't even know?
Quanna Nano has never stopped its research on graphene coatings. As a new type of nanomaterial, graphene is an important raw material that drives technological innovation in the coatings industry. In 2017, graphene coatings achieved a major breakthrough and began to be gradually applied in various industries, breaking foreign monopolies, and graphene coatings developed rapidly. 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-duty anti-corrosion treatment in the marine field. Utilizing the physical barrier properties of graphene in coatings can improve the anticorrosion, antifouling, and flame retardant effects of coatings; using its high electrical conductivity and high thermal conductivity, conductive coatings, heat dissipation coatings, electromagnetic shielding coatings, etc. can be developed. 1. Graphene heavy anti-corrosion On November 23, at the site of the Zhoushan 500 kV interconnection project, more than ten staff members were spraying 'graphene heavy anti-corrosion paint' on the neatly stacked iron tower pipes on the ground. The world's tallest tower under construction wears an anticorrosive '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, so as to extend the life of the poles and towers, has been an important research topic for 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 u200bu200bthe coating. Quanna Nano makes full use of this point to develop GN-706 graphene high thermal conductivity and heat dissipation coating, which can improve the thermal conductivity of the heat dissipation coating. The coefficient is increased to 20W/MK, and the thermal conductivity of the thermal paste is 10 times the thermal conductivity of 2W/MK and the thermal conductivity of the graphene thermal coating. GN-706 graphene high thermal conductivity and heat dissipation coatings are used in LEDs, stage equipment, and electronic equipment. Quanna Nano also made an interesting small experiment to allow more people to 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 rate between the aluminum plate without graphene coating and the aluminum plate with graphene coating. Moreover, with the graphene coating, the heat conduction is relatively uniform and extremely large. Improved heat dissipation efficiency. Guangna Nano unique 1, aviation-grade nano-composite ceramic technology process, the effect is more stable. 2. Unique and mature nano-ceramic dispersion technology, the dispersion is more uniform and stable; the interface treatment between nano and micro particles is efficient and stable, ensuring that the nano-composite ceramic coating and the substrate have better bonding strength and better performance; the formulation of nano-composite ceramics is compounded , Let the nanocomposite ceramic coating function controllable. 3. Nano-composite ceramic coating presents a good micro-nano structure (the nano-composite ceramic particles completely wrap the micro-composite ceramic particles, and the gaps between the micro-composite ceramic particles are filled with nano-composite ceramic particles to form a dense coating. Nano-composite ceramic particles infiltrate and fill the repair base On the surface of the material, it is easier to form a large number of stable intermediate phases between the nanocomposite ceramics and the substrate), ensuring that the coating is dense and heat conductive Graphene coating applications are widely used. Nano graphene coatings can be applied to heat exchangers, lighting radiators, heat-conducting devices, car lights, rectifiers, batteries, computer all-in-ones, displays, energy storage, and other materials such as metals, ceramics, and glass. 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 effects 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.
