Der Vergleich der Radiothermolumineszenz (RTL)-Erscheinungen zeigt, daβ die intensive Lichtemission von PVC-DOP-Mischungen im Tieftemperaturbereirch durch die Weichmacher-Komponente bestimmt wird. Ein weiteres Lumineszenzmaximum im system PVG/Weichmacher bei Temperaturen >250 K ist dagegen PVC-matrix-determiniert. Ein wesentliches Argument fur diese Schluβfolgerung ergibt sich vor allem aus Lumineszenzmessungen an Hart-PVC. Die RTL des weichmacherfreien PVC beruht offensichtlich nicht nur auf der Rekombination von Elektronen. sondern auch von Chloridionen mit polymeren Kationen, wobei enhtaltene Verunreinigungen als Lumineszenzzentren fungieren.

Steel specimens having a size of 20 mm × 15 mm × 0,3 mm were irradiated in a reactor VVR-S during 80 hours at a neutron flux of 2 × 1017 nm−2 s−1. The cooling time before starting the corrosion experiment was one month. The corrosion tests were performed according to a Czechoslovak Standard. Liquid portions of the corrosion medium taken during the corrosion process were measured gamma-spectrometrically. The experiments gave evidence that in the initial stage of corrosion the compounds of metal are dissolving unequable. In the next phase a steady state is set up, but in many cases the disproportion in solubility of the compounds lasted on. In practice it is very important to know corrosion speed and ratio in a steady state.","PeriodicalId":177114,"journal":{"name":"April 1982","volume":"104 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117238694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
