Povzetek
Ugotavljali smo povezave med rezultati določanja oprijemnosti premaznih sistemov, ki jih dobimo z različnimi metodami. Na bukove vzorce smo nanesli različne premazne sisteme: vodni, UV utrjujoči vodni in poliuretanski lak. Za določanje oprijemnosti smo uporabili različne metode, in sicer test s križnim rezom (SIST EN ISO 2409) ter 3 različice metode z odtrgovanjem pečatov (SIST EN 4624). Tako dobljene rezultate smo med seboj primerjali in statistično obdelali z računalniškim programom Statgraphics Centurion XVI. Izvedli smo test variance in nato z Duncanovim testom pri 95 % stopnji zaupanja dobljene rezultate razvrstili v homogene skupine. Rezultate, ki jih dobimo z metodo križnega reza, je nesmiselno primerjati s tistimi, ki jih dobimo s postopkom odtrgovanja pečatov. Možna pa je primerjava rezultatov, dobljenih s 3 različicami metode odtrgovanja pečatov. Najboljšo oprijemnost smo dosegli z UV-lakom, sledil je poliuretanski lak, najslabše rezultate pa smo dobili pri vodnem sistemu.

ǂA ǂcomparison of different methods for the determination of adhesion of cured coatings on wood |
Sekundarni povzetek: |
We were establishing the link between the results of determining the adhesion of coating systems obtained by various methods. We applied different coating systems on beech wood samples: water-borne, UV-curing water-borne and polyurethane finishes. To determine the adhesion we used different methods, namely the cross-cut test (SIST EN ISO 2409), and 3 versions of the pull-off test method (SIST EN 4624). The results were compared and statistically analyzed with a Statgraphics Centurion XVI computer program. We conducted a test of variance, after which the results were sorted into homogeneous groups with Duncan's test at the 95 % level of confidence. Comparison of the results obtained by the method of cross-cutting with those obtained by the pull-off test method does not make any sense. However, it is possible to compare the results obtained by the 3 versions of the pull-off test method. The best adhesion strength was achieved with UV-curing finish, followed by the polyurethane coating, and the worst results were obtained with the water-borne system. |
