15khz Ultrasonic PCB Generator For Disposable Surgical Masks Welding
Ultrasonic PCB generator can be used in mask machine welding equipment. It mainly uses ultrasonic technology to transmit ultrasonic energy to the welding area through the upper weldment. Due to the large sound resistance at the interface between the two welding areas, local high temperature will be generated. In addition, due to the poor thermal conductivity of plastic, nylon, chemical fiber, non-woven fabric, multi-layer cloth, gold cloth and other materials, they can not be distributed in time and gather in the welding area, resulting in the rapid melting of the two contact surfaces. After adding a certain pressure, they are integrated into one. After the ultrasonic wave stops working, the pressure will be maintained for a little time to solidify and form, so as to form a solid molecular chain and achieve the purpose of welding. The welding strength can be close to the strength of the raw material body. This is why many manufacturers need to use Rex ultrasonic for mask production and welding. It has the advantages of fast, clean, safe, stable performance and high output, and makes the wearer's ears comfortable, No pressure, good filtering effect of mask filter cloth layer, perfect for Asian face shape, which is greatly applicable to the current epidemic situation, personal ordinary protective mask, high pollution red area protective mask, and high pollution industries such as construction and mining.
