Shielding Spray – Ultrasonic Atomizer Nozzles – Cheersonic

Dispersion of shielding coating: In order to improve the dispersion effect of graphene, an ultrasonic intelligent disperser is selected. First, an ultrasonic intelligent disperser is used to pre-disperse graphene to reduce the high surface energy of graphene, use electrostatic repulsion and steric hindrance to avoid agglomeration of rabbit graphene, and further improve the dispersibility of graphene.

Ultrasonic coating application technology research and substrate surface treatment process and spraying process: According to different substrates, determine the corresponding surface treatment process to obtain a surface with a certain porosity and roughness, thereby increasing the adhesion of the coating. For substrates that are prone to internal stress, such as engineering plastics, physical or chemical methods should be used to eliminate the stress before spraying to prevent the coating from cracking due to stress. Determine the spraying process of the shielding coating, quantify the spraying pressure, spray fan, spray speed and other process parameters, and conduct research on the construction cycle of the coating.

The beneficial effects of the application of ultrasonic coating are: taking into account both the civilian and military fields, using the high conductivity of graphene to develop lightweight, long-lasting, serialized electromagnetic shielding coating materials, and realize the application in military equipment and high-end household appliances. Application, so as to effectively improve the electromagnetic protection capability of military equipment, reduce the electromagnetic radiation of household appliances, and finally realize an electromagnetic shielding coating preparation method for the industrial application of graphene electromagnetic shielding coatings.
