Abstract
The article reviews various methods of documents protection against the destroying effect of micromycetes. The methods considered have been in use since the third decade of the 20th century. The authors provide information on the search of new disinfectants from the list recommended by the Ministry of Health of Ukraine. In particular, these include nipagin and a new product "Valeus-D" (analog of the investigated earlier Polidez). The received results of study of minimal concentrations of Valeus-D disinfectant alcohol and water solutions having effect on microscopic fungi are analyzed. Data on the influence of nipagin, "Valeus-D" and 70% ethanol on resistance to fungi, chemical and physicomechanical characteristics of model samples of four types of paper (rag, typographical, offset, newsprint) are compared. The experiments' results indicate, that 1% nipagin, 2% and 4% "Valeus-D"(pH 9) render the highest resistance to fungi. It is revealed, that 70% ethyl alcohol and 1% nipagin had the least influence on the physicomechanical properties of model samples of paper. Accentuated is the need to continue pilot studies of the use of other modern effective disinfectants and other types of paper
