塑料的粘结技术除溶剂法、粘结剂法、热空气法、机械加热法、摩擦法、超声波法外,还有高频法。高频法是利用被粘结物体自身的内部加热来进行粘结的技术,因此,即使被粘结的物体很厚,也能在它的表面和内部之间无温差的情况下进行均匀加热。由于电极本身的温度和室温相同,故而不会引起热量的损失。整个粘结过程可在很短时间内完成,是生产上有效的方法。高频电介质加热粘结法:它适用于粘结介质损耗较大的塑料(如聚氯乙烯)。它的原理如下:把电介质 Plastic bonding technology in addition to solvent method, binder method, hot air method, mechanical heating method, friction method, ultrasonic method, there are high-frequency method. The high-frequency method is a technique that uses the internal heating of an object to be bonded for bonding, so even if the object to be bonded is thick, it can be uniformly heated without any temperature difference between its surface and its interior. Since the temperature of the electrode itself is the same as the room temperature, it does not cause a loss of heat. The entire bonding process can be completed in a very short period of time, which is a productive method. High-frequency dielectric heating bonding method: It is suitable for bonding plastic loss of larger plastic (such as polyvinyl chloride). Its principle is as follows: the dielectric
