| چکیده | ||
| Polymers have been extensively employed as stone preservatives for monuments since thirty years, has been tested on specimens appropriately prepared and submitted to ageing simulating reliable outdoor environment. Growth of microorganisms on different materials may cause aesthetic and structural damage. The structure of polyvinylidene fluoride (PVDF) exhibits an excellent chemical resistance, an easy processing and an excellent UV stability; but disadvantages such as inability to produce a glossy finish and the high cost, make it indispensable to introduce a secondary polymer. The poly (methyl methacrylate) (PMMA) has a low price compared to PVDF but it deteriorates easily by UV radiations exposure; this character limits its use as protecting agent for stones. The results showed a protecting effect which can also be an inhibiting effect if complete dissolution of the blended polymers in nutritive medium is reached. | ||
