Composite Railroad Ties Obtained by the Energy Efficient Recycle of Wooden Railroad Ties

Abstract

The article presents the result of research in the field of processing wooden railroad ties and thermoplastic polymer household waste with obtaining composite railroad ties under conditions of energy efficiency of technological processes. The wood of the used wooden ties contains a significant proportion of chemical compounds based on creosote. As a result of the thermal and mechanical action, the creosote compounds in the wood form hydrophobic surfaces, thereby fulfilling the function of the bonding additives. Under the above-mentioned conditions, hydrogen bonds are formed between the components of the wood composite, that, in its turn, allows achieving the task of creating a functional composite, which varies in the compound of elements and the modes of production processes. Experimental studies were held on the nature of justification and correction of theoretical studies. The experimental stand of composite production is realized on the principle of energy efficient cooling cycles of the obtained composite with heat transfer for heating the initial components. The obtained results of experimental studies exceed the regulation values by every measure. The comparison justifies the quality of the experimental samples obtained with respect to these values.
