Experimental studies of changes in the acoustic properties of spheroplastics

The development of methods for non-destructive testing of water absorption of products from spheroplastics without the need to dismantle them is an urgent task. The ultrasonic method of the acoustic type for solving this problem can become an alternative to the currently used radiographic methods, hydrostatic weighing and mechanical testing. The purpose of this work is to study the relationship between the acoustic characteristics of spheroplasts and their water absorption. The objectives of this work are to estimate the propagation velocity of an ultrasonic wave in spheroplastics at different stages of research: in the initial state of the samples, after mechanical treatment, after water absorption, and after drying. Water absorption was indirectly estimated by weighing the samples. A relationship has been established between the acoustic characteristics of spheroplasts and their water absorption, which emphasizes the scientific novelty of the ongoing research. The results obtained are consistent with the theoretical prerequisites and provide grounds for further experimental studies to develop a technique for non-destructive testing of products made of spheroplasts.
