The advent of graphene has caused huge waves in the scientific community and a worldwide research boom. Especially in the application of high thermal conductivity industry, graphene thermal radiation coating made of graphene is coated on the surface of high temperature devices and equipment because of its very good thermal conductivity, high thermal conductivity and high emissivity. Its heat is transferred to the coating, and is transferred to the outside world with high radiation heat dissipation capacity, so as to achieve the effect of efficient heat transfer or cooling.

At present, many electric heater manufacturers have added graphene thermal radiation coatings to the radiators as their heating materials to increase the heating effect. The main advantages of graphene materials used in electric heaters are: high thermal conductivity and less heat loss.

We all know that an important indicator of electric heaters is the thermal conductivity of the heating material. The higher the thermal conductivity, the less heat is wasted, and the heat converted from electricity is used for indoor heating. Low thermal conductivity means that a large part of the heat generated is not conducted and not used for heating. Graphene has a very high thermal conductivity, and the heat conversion rate is as high as 99.7%. The thermal conductivity is 23 times that of aluminum, and the heating efficiency is more than 10 times that of aluminum. After the electric heater is connected to the power supply, the heat generated by the electric heater is lost in the process of conversion and transmission, and it can basically be used to provide heating in the room with less heat loss.

The far-infrared waves released by graphene are easily absorbed by the human body. During the heating process of graphene material, it dissipates heat through far-infrared waves, and the far-infrared wavelengths it releases are 8~15UM. The wavelengths of this band are very similar to the far-infrared wavelengths of the human body, so the heat is easily transmitted to the deep tissues of the human body. Promote human blood circulation and relieve fatigue.

In the coating process of graphene thermal radiation coating, the formed coating film has good stability and can be used for a long time in an environment above 300 °C without
Falling off, yellowing, cracking and other phenomena occur. The graphene added in the coating improves the infrared heat radiation effect of the coating film, and also improves the heat dissipation performance of the parts after painting, and also significantly improves the corrosion resistance and high temperature resistance of the parts.

In the field of heat conduction and heat dissipation, Hefei Vigon Materials Technology has launched a new type of high heat conduction and heat dissipation graphene heat radiation coating WJ-5076 series products, the thermal conductivity exceeds 20W/M.K, and the heat conduction and heat dissipation are stable. High temperature and thermal shock resistance, good thermal shock resistance. Cost-effective, environmentally friendly, non-toxic, convenient construction and stable performance.

The application scope of graphene thermal radiation coating is as follows:

Graphene thermal radiation coatings can be widely used in high-power heaters, radiator surfaces, heating equipment, LED lights, landscape lights, air conditioner radiators, vehicles, engine cooling, automotive water tank cooling, industrial drying equipment, industrial electric heaters , heat pipes, transformers, electrical cabinets, industrial heat exchangers, rail transit heaters, chemical pipes, boilers, etc.
