PVC profile extrusion

U početku ovog rada opisani su polimerni materijali, njihova podjela, karakteristike kao i područje njihove primjene. Nakon toga opisani su postupci dobivanja poli(vinil-klorida), svojstva i dodatci koji se dodaju kako bi poboljšali svojstva. Vrhunac završnog rada se odnosi na najrašireniji postupak praoblikovanja polimernih materijala, ekstrudiranje. Taj postupak detaljno je opisan, kao i dijelovi ekstrudera i linija ekstrudiranja. Nakon toga, slijedi opis postupka zavarivanja PVC profila.This paper describes the polymer materials, their distribution, their characteristics and the scope of their application. After that, methods of obtaining poly(vinyl chloride), properties and which additives are added to enhance properties, are described. The most important part of the paper is related to the most widespread polymerization process, extrusion. This procedure is described in detail, as well as parts of the construction and extrusion lines. After that there is a description of the welding procedure of the PVC profile
