Abstract

A scientific article presents the main goals that can be achieved through the use of co-extrusion processing technology and equipment for the processing of secondary polymer and building materials. The main indicator of the multilayered product being created in the process of co-extrusion processing of secondary building and polymer materials is determined. The methods of quality control of the mixture preparation from secondary materials and quality of manufacturing of a finished co-extrusion product are considered. A reference mathematical model of a co-extruded product containing secondary building and polymer materials is constructed. Based on the results of the studies, the article presents an analysis of the ecological state of building and polymer wastes. The necessity of further research in the field of improving the model of the formation of a multilayer structure of a given quality for the process of processing this waste is substantiated. For the existing practice of preparing a mixture of polymer and building material wastes, the volumetric costs of components are determined by recipes. An analysis of the equations obtained allows us to refine the recommended numerical values of the percentage of primary polymer on the basis of the required standard strength of the building pipe from secondary materials.

Highlights

The large-scale development of the construction industry requires the creation of new building materials that will be in demand for the creation of buildings and structures
Objectives of the study: 1. Determine the main indicator of the multilayer product being created in the process of co-extrusion processing of secondary building and polymer materials; 2
When designing the structures of co-extrusion machines for processing secondary building and polymeric materials with the manufacture of a multilayer structure, the normative strength of the middle layer of the co-extruded product is used as the main indicator of the multilayered product being created, the normative strength of the middle layer of the coextruded product is used

Summary

Introduction

The large-scale development of the construction industry requires the creation of new building materials that will be in demand for the creation of buildings and structures. The process of construction is inevitably associated with the emergence of waste (broken brick, cinder block, remains of concrete and other building structures). This will allow, in this way, to solve the resource problem of new building materials having a significantly lower cost due to the use of secondary building materials in their structure
