BASED ON THE TECHNOLOGY OF MANUFACTURING WELL COVERS FROM LOCAL POLYMER WASTE RAW MATERIALS

Todays, polymer composite materials are used to produce parts and products of various shapes and sizes. In this research work, several research works on existing and modern methods on a number of technologies for the production of well caps were analyzed, and the technology of obtaining well caps from local polymer waste raw materials was justified scientifically and practically. In particular, in the creation of well caps, the formation of a composition in the composition and microstructure of the materials was studied, and a mixture based on the mass fraction of secondary polyethylene, dibutyl phthalate (DBP), polyethylene polyamine (PEPA), pigments and sand raw materials was formed. A mixture was prepared from the secondary raw material by extrusion method, and the cover was formed using the mixture press mold and the finished part was obtained. The chemical resistance, relative bending strength, pressure resistance indicators of product were determined by scientific-research work. On the basis of the obtained results, the construction and road construction industry was founded on the technology of production of products that are six times cheaper and lighter than traditional cast iron manhole covers.
