The effect of an ultrasonic welding machine is inversely proportional to the modulus of elasticity, coefficient of friction, and thermal conductivity, and inversely proportional to density, specific heat capacity, and melting point. The welding effect of the ultrasonic welder is mainly related to the melting point of the material and the surface friction coefficient. These parameters vary with mat...

Ultrasonic preparation of graphene As the special properties of graphite are already known, several graphite preparation methods have been developed. In addition to chemically producing graphene from graphene oxide in a multi-step process, very strong oxidizing and reducing agents are also required. In addition, compared with graphene obtained from other methods, graphene prepared under these hars...

Ultrasonic energy acts on the medium, which will cause high-speed and subtle vibrations of the particles, resulting in changes in mechanical quantities such as speed, acceleration, sound pressure, and sound intensity, which will cause mechanical effects. Ultrasound is the propagation form of mechanical energy, which is related to the wave process and will produce a linear effect of vibration. When...

Ultrasonic food processing involves an ultrasonic food cutting knife (guillotine) that produces an almost frictionless surface where the food will not stick or deform. Products are cut cleanly on the surface, including fillings such as nuts, raisins, dried fruits or chocolate chips, without shifting or ploughing. Many of the most prestigious food manufacturers in the world are using ultrasonic foo...
