Nel campo dei Beni Culturali le sue prime applicazioni riguardano la verifica dell\u2019efficacia di trattamenti atti a ridare coesione alla superficie pittorica di affreschi. Successivamente \u00e8 stato applicato su malte (di calce, cementizie , di terra) sempre con lo scopo di verificare la ricoesione superficiale indotta da trattamenti di varia natura.<\/p>\n<p><em>\u00a0<\/em><o:p><\/o:p><\/p>\n<p><strong>DETTAGLI TECNICI<\/strong><o:p><\/o:p><\/p>\n<p>Si utilizza un nastro adesivo con elevata omogeneit\u00e0 e caratteristiche note con particolare riguardo alla\u00a0 resistenza a trazione e adesione in accordo rispettivamente con la norma ASTM D3759 e ASTM D 3330 ( ad es.3M scotch 1280). Una bilancia analitica a tre cifre decimali e uno strumento per avere una pressione omogenea del nastro sulla superficie da analizzare sono altri attrezzi utilizzati per la prova. Il nastro adesivo viene tagliato in modo da avere una certa superficie di prova \u00a0(ad es. 7x2cm), viene pesato e viene applicato sulla superficie con una pressione costante, e successivamente rimosso, avendo cura di mantenere uno velocit\u00e0 di strappo costante.<br \/> Il nastro rimosso viene pesato e la differenza con il peso precedentemente acquisito permette di valutare la quantit\u00e0 di materiale rimosso. Tutte queste operazioni vengono ripetute in una stessa area per almeno 5 volte utilizzando ogni volta un nuovo nastro adesivo. Cos\u00ec facendo si pu\u00f2 vedere un andamento della coesione con strappi successivi e confrontare aree non trattate con aree trattate.<\/p>\n<p>Questa tecnica \u00e8 un metodo efficace per la determinazione dello stato di coesione superficiale di materiali molto disgregati o con un importante spolverio superficiale comprendendo anche pietre tenere, come ad esempio tufi calcarei, con simili tipologie di degrado e per verificare l\u2019efficacia di trattamenti il cui scopo sia essenzialmente di evitare uno spolverio della superficie.<\/p>\n<p>&nbsp;<\/p>\n<p>Referente:<o:p><\/o:p><\/p>\n<p>Oana Adriana Cuzman <a href=\"mailto:oanaadriana.cuzman@cnr.it\">oanaadriana.cuzman@cnr.it<\/a><\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"http:\/\/www.e-rihs.it\/wp-content\/uploads\/2022\/02\/MOLAB-1_EQUIPMENT_peeling-test.pdf\" rel=\"attachment wp-att-4696\">Scarica la scheda completa<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>LABORATORIO: CNR ISPC NOME STRUMENTO Metodo peeling &nbsp;
