"Ultrasonic in the actual ultrasonic spray nozzle transmission process, will meet the influence of many factors, and produce different degree of attenuation, ultrasonic attenuation mainly have three scattering, diffusion, and absorption.
Scattering attenuation
If you meet some obstacles, some ultrasonic would no longer be carried out in accordance with the original direction of propagation degree of dynamic, ultrasonic scattering attenuation will occur at this moment, scattering attenuation and propagation is related to the material object, if the spread of ultrasound in solid, scattering attenuation weakens, and if it is in the air, the life of the ultrasonic wave will increase, and in the liquid transmission attenuation, asked the between solid and liquid.
Diffusion attenuation
While common diffusion attenuation ultrasonic handheld welder has nothing to do with the density of transmission medium, the expansion of a scattered attenuation is mainly related to ultrasonic distance in the medium, as the name implies, as long as the ultrasonic transmission within the object distance, the longer the ultrasound will gradually decay, they disappear. www.tanshangyi.cn
Absorption attenuation
Due to the ultrasonic wave travels in Ultrasonic nano dispersion the object back, more or less will make internal objects to produce vibration, the vibration due to exposure to produce friction, along with the increase of the propagation time of ultrasonic and friction heat between objects, under this kind of heat block, ultrasonic energy is a weakened gradually, has finally been completely absorbed.
Ultrasonic welding machine equipment, welding when demand attention points, followed by accelerating the process of industrialization, plastic welding today, as he had no longer use glue adhesion. When the company received two plastic demand when the welding project, most of the engineers can think of using ultrasonic welding. Due to the ultrasonic welding is a kind of high-tech welding method, this method does not need glue, ultrasonic welding is not pure the stench, heated melting plastic ultrasonic welding speed is very fast, need only a few seconds a product completion of welding, the welding product appearance beautiful and no damage. Ultrasonic welding machine equipment is more and more favor by vast users.
