In a study of cellular injection, molding process uses polyvinylchloride PVC. Poly¬mers modified with introducing blowing agents into them in the Laboratory of the Department of Technologies and Materiase of Technical University of Kosice. For technological reasons, blowing agents have a form of granules. In the experiment, the content of the blowing agent (0–2,0% by mass) fed into the processed polymer was adopted as a variable factor. In the studies presented in the article, the chemical blowing agents occurring in the granulated form with a diameter of 1.2 to 1.4 mm were used. The view of the tech¬nological line for cellular injection molding and injection mold cavity with injection moldings are shown in figure 1. The results of the determination of selected properties of injection molded parts for various polymeric materials, obtained with different content of blowing agents, are shown in Figures 4–7. Microscopic examination of cross-sectional structure of the moldings were obtained using the author’s position image analysis of porous struc¬ture. Based on analysis of photographs taken (Figures 7–9) it was found that the coat¬ing containing 1.0% of blowing agents is a clearly visible solid outer layer and uni¬form distribution of pores and their sizes are similar. |
