| Title of the article | Filling of polyvinyl chloride polymer mixture with expanded perlite sand |
| Abstract. | Problem statement. At the moment, the issue of recycling industrial waste that has lost its consumer properties is relevant. Such waste includes spent expanded perlite sand, which is formed in some industries of the Republic of Tatarstan. The use of waste in filling polymers is an important and relevant topic that is associated with improving the properties of polymeric materials, reducing their cost and solving environmental problems. Therefore, the aim of the work is to evaluate the effectiveness of the use of expanded perlite sand as fillers of polyvyl chloride mixtures of polymers. The objectives of the work are to study the surface of different fractions of expanded perlite sand and their effect on the physical, mechanical and technological properties of compositions based on polyvinyl chloride and a polyvinyl chloride-copolymer polymer mixture. Results. The main results of the study showed that fine fractions of the filler have a denser packing due to the predominantly destroyed aggregates. Regardless of the fraction of expanded perlite sand, the strength is at the same level for both the polyvinyl chloride matrix and the polyvinyl chloride-copolymer mixture. At the same time, the filling has a positive effect on the technological properties of the compositions, especially for large fractions (0.315 mm and 0.63 mm), as well as unfractionated expanded perlite sand. Conclusions. The significance of the obtained results for the construction industry is that the use of certain fractions of spent expanded perlite sand can regulate technological processes in the manufacture of profiled and molded products without losing strength properties. |
