Advanced Process Control of Advanced Foam Materials Production using Vibroturbulization Optimal Parameters

Abstract

The foams with high physical and mechanical properties production is one of the most important tasks associated with the needs of the chemical industry, medicine, mechanical engineering and space technology. Well-known methods for foams production are the creation and foaming of aqueous dispersions of high polymers using thermal decomposition of organic and inorganic substances, the use of radiation destruction of a thermoplastic polymer, foaming of polyurethane compositions using the injection of condensed hydrogen under high pressure, etc. All these methods, on the one hand, are not cost-effective and harmless due to the complexity of the technology of the foam production process. The toxicity of thermal decomposition products and the unfavorable effect of the chemical nature of the gas-forming agents impair the properties of the resulting material. On the other hand, these processes only produce specific foams, which severely limit their applicability to a wide range of foams. This article presents the developed advanced technological control of the advanced foams production using the vibroturbulization optimal parameters, which allow the formation of a gas phase by electrolysis of water with a constant electric current and by the subsequent transformation of this gas phase into the micro dispersed electrolytic hydrogen gas bubbles with simultaneous, uniform saturation of the thermoplastic with them at its temperature melting.
