Tuluchenko N. Improving of processing technology of straw stalks of oilseed flax for road constructing

The object of the study - the process of manufacturing non-woven materials for road construction from straw stalks and fibers oilseed flax. The purpose of the study - obtaining of the same type linen and fiber with new physical and mechanical parameters suitable for the production of nonwoven materials used in road construction, due to optimization of the technological process of crumpling of oilseed flax straw stems. Methods of research - the methods of theoretical and experimental research, the method of system analysis, the principle of modeling processes, methods, determined by the current standards of Ukraine on the corresponding geoproduction. The possibility of using straw stalks of oilseed flax in the production of biomats and non-woven materials for road construction based on in-depth study of anatomical and morphological structure of stems is substantiated. With the help of regression analysis, mathematical models of dependence of physical and mechanical characteristics of the obtained nonwoven materials and biomat on the parameters of processing are developed, on the basis of which the optimal technological regimes for obtaining new geomaterials are determined. The correspondence of physical and mechanical characteristics of the developed geomaterials to the requirements of domestic and international standards and other normative documents is established. It is proved that geomaterials, depending on the method of their manufacture, can be used for different intended purposes: for strengthening of road slopes or auto cover. The area of use - textile industry and road construction.
