PROSPECTS OF METALLIZATION OF AGRO-INDUSTRIAL COMPLEX PRODUCTS FROM REACTOPLASTS IN THE PROCESS OF THEIR MOLDING

Abstract

To date, one of the urgent tasks is to improve the performance characteristics of polymer products used in machines and aggregates of various industries - agro-industrial complex (AIC), mechanical engineering, etc. Despite the high manufacturability of thermoplastics, especially responsible products are made of thermosetting polymers based on epoxy and phenol-formaldehyde resins. Based on the technology of magneto-thermal reinforcement of the thermoplastics surface, a similar technology has been developed in relation to products made of reactoplastics directly in the process of their production. It uses a mold made of ferromagnetic material, along the perimeter of which there is a system of electromagnets that prevent the displacement of particles along the inner surface of the mold during the entire process of obtaining a metallized surface layer on the product. The experimental samples obtained showed tribotechnical and mechanical properties of the surface comparable to similar properties of the reinforcing material (surface hardness increased from 30-40 MPa to 150-240 MPa). The developed technology opens up wide possibilities for modifying the surfaces of products of a wide range of purposes made from almost any polymer materials, since the feature of this technology is the introduction of reinforcing particles into a notoriously viscous polymer layer directly during the molding of products.
