In this paper, we analyze the origin and development of the process of low frequency ultrasonic cavitation in the liquid epoxy oligomer of ED-20 brand depending on time of its insonation. We provide the rationale for the physical model of low frequency ultrasonic cavitation in liquid compositions of epoxy polymers. Specifically, it allows choosing effective parameters of this process (frequency, amplitude, intensity) and at the same time ensuring structural integrity of sonicated epoxy compositions. Also, it helps improving technological and operating properties of liquid and hardened epoxy polymers on their basis. We propose to determine effective values of amplitude and intensity of ultrasonic vibrations by studying technological and operating properties of liquid and hardened epoxy polymers. Through experiments conducted, we define the extreme of change of these properties from parameters of ultrasonic treatment. [ABSTRACT FROM AUTHOR] |
