| Title of the article | Research of properties hybrid binders prepared with use of cavitation processing |
| Abstract. | The twenty-first century – the century of biotechnology and nanotechnology, general information, electronics and ultrasound. In recent years, ultrasound, described in detail in this paper, begins to play an increasing role in industry and research. Successfully carried theoretical and experimental research in the field of ultrasonic cavitation and acoustic streaming. This allowed to develop new processes that occur when exposed to ultrasound in the liquid phase. At present, a new trend of Chemistry – Chemistry ultrasound is formed. This will accelerate many chemical processes and gain new substance. Scientific studies have contributed to the emergence of a new section of acoustics – molecular acoustics that studies the molecular interaction of sound waves with matter. There are new applications of ultrasound: introscopy, holography, quantum acoustics, ultrasound fazomeriya, acousto-electronics. So, in the present research regularities of influence of cavitation treatment on technological and operational properties of hybrid binders on the base of polyisocyanate and liquid glass are presented. The regularities of the effect of time of cavitation treatment on the technological properties of the binder: viscosity, gelatination, the time of heat treatment and the density of the hybrid binders are installed. 20-25 min – the optimum time of cavitation processing of the liquid glass are selected. It should be noted that using the developed hybrid binder for the manufacture of composite materials the low viscosity and rapid curing while maintaining high physical and mechanical properties and heat resistance are important technological advantages. Therefore, an cavitation processing of liquid glass for 20 min, resulting in a significant reduction in viscosity and reducing the heat treatment by providing a superfine dispersing, feasible and technologically justified. |
