Application of basaltic compositions for the production of biocidal paper
One of the main problems today is the storage of funds, provision of storage conditions, the absence of mold, microbiological dispersions in the air, processing of documents, detoxification of previously processed materials.
In this work, samples of papers (condenser, writing, carton for lamination) and usage of biocidal materials (Polydez, Gembar and Metatin) were investigated. The technology of processing samples is not very simple. Biocidal effects were carried out on test cultures of microscopic fungi taken from damaged documents.
In addition, samples of papers processed with composite mixtures containing basalt and cellulose fibers, montmorillonite clay and sodium resin salts (SSRA) or sodium humate (SH) were studied in parallel. Aging of samples was monitored by indicators such as the material's whiteness and breakthrough strength (n.d.f.) - the properties that are sensitive to the aging process.
It has been proved that samples containing basalt and cellulose fibers, montmorillonite and sodium salts of resin acids (or sodium humate) are more likely to suppress the spread of fungi and microorganisms than official state biocidal materials.
Therefore, in this work it is proposed the material and composition mixture, which guarantees certain physical and mechanical properties of the finished product and has a much simpler and cheaper technology to obtain the disinfecting material.
