Course content
1) Basic concepts and classification of plastics - fundamentals of deformation behavior, nomenclature of polymers, additives and affect the workability. 2) The melt rheology of plastics - rheology during processing, shear viscosity - temperature dependence, on pressure, MW, influence of additives on the viscosity of polymers rheometry - types of rheometers, their field of application (extrusion and rotational rheometers, normal and shear stress during flow normal viscosity and its manifestations. 3) Edit and preparatory processing of polymeric materials - basics drying, crushing, dissolving and dispersing, coloring, mixture preparation - mixing and kneading, mixing and kneading machines, mechanism of formation of the mixture, tabletting, granulation lines preparatory processing, milling and processing of waste plastics. 4) Injection - machinery, plasticizing and injection unit, clamping unit (the relative position of injection. And closing units) drive, control and regulation technology, management and regulation of injection molding machines. 5) Injection molds - the multiplicity, gating, venting forms, basic methods of injection ejection from the mold, tempering injection. forms. 6) injection technology - injection cycle, in the form of ratios, the impact of technological conditions, filled thermoplastic injection molding, structural foam, thermosetting, multicomponent injection molding, injection sandwiches, possible faults in injection molding. 7) Reaction injection - low and high pressure process of structural foam. 8) Introduction to the rolling technology - mixing on two-roll mill, types of calenders and their use (structure calenders) calender lines. 9) Extrusion (extrusion) - Function of the auger inlet zone - friction performance, transition zone, zone output, dwell time, kneading performance, types of endless screws, extrusion head, extrusion process dynamics, similarity, technology using extruders. 10) lamination technology - the types of lamination technology, the use of technology. 11) Production of glass laminates - discontinuous and continuous processes. 12) Stamping - mechanical and hydraulic presses, molding of thermoplastics and thermosets, presses for glass laminates, floor presses for flat moldings, rotary presses. 13) Molds - the main part of the mold division extrusion mold, ejecting the moldings, molds heating, pressing technology. 14) Blowing of hollow bodies - extrusion and injection molding process, blowing with stretching. 15) Technology foaming - factors and processes. 16) Shaping - formability finished products, machinery, technology 17) Rotary sintering - materials cycle in the form of ratios. 18) Preparation of liquid systems - dispersion systems - dipping, brushing, casting and molding. 19) Spinning - procedures for fibers. 20) Concatenation - mechanical, bonding and adhesives - adhesion theory, preparation of the material being bonded, apply adhesives, creating connections, adhesives, laminating. 21) Welding - contact, filler material, high frequency, ultrasonic, friction, radiation. 22) Finishes - painting, printing, embossed, polishing and plating of plastics, protection, plastic powder

  • Preparation for exam - 15 hours per semester
Learning outcomes
The aim is to present complex problems of polymeric materials; their basic physico-chemical properties, production, and preparation of polymer materials. The important part is to introduce the thermal treatment of plastics and their processing by injection, stamping, extrusion, etc. together with the introduction of the basic mechanisms, principles and relevant machinery. Another aim is to introduce surface treatment of polymer materials.
Students will get knowledge of polymeric materials; their basic physico-chemical properties, production, and preparation. An integral part of the acquired knowledge is thermal treatment of plastics and their processing by injection, stamping, extrusion, etc. together with basic mechanisms, principles and relevant machinery. In addition, students will know the basic surface treatments of polymeric materials.
Prerequisites
no requirements
