Insulation systems based on foamed plastic

Abstract

In the design and construction of residential and industrial buildings outbuildings, it is necessary to use effective thermal insulation materials that provide a comfortable microclimate in the room, as well as the required conditions for implementing technological processes. An essential factor is the reduction of the negative impact on the environment, which is expressed both in the reduction of energy consumption and in the possibility of rational use of industrial waste for partial replacement of the main raw material components. To increase the efficiency of heat-insulating materials based on foamed polyethylene, it was necessary to develop a technique for selecting the composition of synthetic polyethylene foam matrix, considering the possibility of using secondary modified polyethylene foam at different foaming modes. The compositions of modified polyethylene foam were selected using statistics methods and analytical optimization. The developed bases of optimization and composition selection methodology allowed to establish optimal consumption values of main components and process parameters corresponding to the specified requirements. Using alignment charts, the solution of the predictive problem of estimation of values of strength and average density of foamed polyethylene depending on the value of consumption of main components was realized.
