20.500.12556/RUL-187473 Razvoj postopka kondicioniranja polimernega izdelka Development of a Conditioning Process for a Polymeric Component Kondicioniranje polimernih izdelkov je ključnega pomena za zagotavljanje zahtevane vsebnosti vlage in dimenzijske stabilnosti ob dobavi kupcu. Raziskava je bila izvedena na izdelku Zobnik BR223 iz poliamida PA6 GF30. Eksperimentalni del je vključeval primerjavo naravnega in pospešenega kondicioniranja v klimatski komori, analizo vpliva časa, temperature in relativne vlažnosti ter preverjanje vpliva položaja in orientacije izdelkov med kondicioniranjem. Vsebnost vlage je bila določena z metodo Karl Fischer, dimenzijske spremembe pa s koordinatnimi meritvami. Rezultati so pokazali, da program kondicioniranja pri temperaturi 80 °C in relativni vlažnosti 90 % v trajanju 8 ur zagotavlja zahtevano vsebnost vlage po stabilizaciji izdelkov. Položaj in orientacija vzorcev nista bistveno vplivala na enakomernost kondicioniranja. Kondicioniranje je izboljšalo dimenzijsko skladnost izdelkov, saj so bile po kondicioniranju vse analizirane karakteristike znotraj predpisanih toleranc. Razviti postopek predstavlja ustrezno osnovo za industrijsko uporabo pri kondicioniranju polimernih izdelkov. Conditioning of polymeric components is essential for ensuring the required moisture content and dimensional stability at the time of delivery to the customer. The research was conducted on the BR223 gear manufactured from PA6 GF30 polyamide. The experimental work included a comparison of natural and accelerated conditioning in a climatic chamber, an analysis of the effects of conditioning time, temperature, and relative humidity, as well as an evaluation of the influence of component position and orientation during conditioning. Moisture content was determined using the Karl Fischer method, while dimensional changes were evaluated by coordinate measurements. The results showed that a conditioning program at 80 °C and 90% relative humidity for 8 hours ensures the required moisture content after stabilization of the components. The position and orientation of the specimens had no significant effect on the uniformity of conditioning. Conditioning improved the dimensional conformity of the components, with all evaluated characteristics remaining within the specified tolerances after conditioning. The developed conditioning procedure provides a suitable basis for the industrial application of polymeric component conditioning. kondicioniranje polimerni izdelek poliamid vsebnost vlage dimenzijska stabilnost conditioning polymeric component polyamide moisture absorption dimensional stability true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-09-11 08:30:27 2026-09-11 08:30:30 2026-09-12 04:29:24 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 289947 49433.pdf 49433.pdf 1 6FB29871513B6F4EB524A8EC1A92907A 60c0a13cfca97273649b491b6f39f3b3ad72c432fc8a23d11aee8bb41716507c 4220b057-adaa-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247107 Fakulteta za strojništvo 0 0 0
