Description
Изобретение относитс к реставрационным работам, преимущественно может быть использовано при обработке красочного сло и основы монументальной живописи на лессовой штукатурке, открытой при археологических работах на территории древних поселений.The invention relates to restoration work, mainly can be used in the processing of the paint layer and the foundations of monumental painting on loess plaster, discovered during archaeological work in the territory of ancient settlements.
Целью изобретени вл етс сохранение и воссоздание подлинника при одновременном повышении долговечности.The aim of the invention is to preserve and recreate the original while enhancing the durability.
П р и м е р 1. На раскопе ДТ-24 древнего городища Дальверзин-тепе бьт выбран участок стены с обильным выступлением солей. Поверхность стены расчищали от загр знени , удал ли выступавшие соли и раздел ли на п ть фрагментов размером 50x50 см. Первый контрольный фрагмент пропитывали 10%-ным раствором полибутилметакрила- та (ПМБА) на ксилоле 15 раз, участокPRI me R 1. At the DT-24 excavation site of the ancient city of Dalverzin-tepe, a section of the wall was selected with abundant salt outcrop. The wall surface was cleared of contamination, the salted salts were removed and divided into five fragments 50x50 cm in size. The first control fragment was soaked with 10% polybutyl methacrylate (PMBA) solution on xylene 15 times, section

Как видно из табл.1, введение ПМК позвол ет химически обезвредить соли, наход щиес в поверхностном слое стены.As can be seen from Table 1, the introduction of PMK makes it possible to chemically neutralize salts that are in the surface layer of the wall.

Пример 4. Модельные кубики из глины, размером 2x2x2 см были обработаны 1%-ными растворами полиметак- риловой кислоты, имеющими разные мол.м. Обработка проводилась путем последовательного 15-кратного нанесе- д НИН раствора полимера кистью на верхнюю грань кубика. После высушивани кубики подвергались испытани м на механическую прочность. Измерение предела прочности на сжатие проводилось на Example 4. Model clay cubes, 2x2x2 cm in size, were treated with 1% solutions of polymethacrylic acid having different mol.m. The treatment was carried out by sequential 15-fold deposition of a NIN polymer solution with a brush on the upper face of the cube. After drying, the cubes were subjected to mechanical strength tests. The measurement of compressive strength was carried out on
