Leading industrial countries display the growth of paper industry even more than other industries. The paper is and was very important for our civilization. Technical industries also require the paper. The electro-technical, radio-technical industries use widely various kinds of paper for the production of things like cables, condensers, radio-diffusers, resistors, TV-sets and so on. In the chemical industry papers are used for chromatography, electrophoresis etc. But besides of clear advantages for simple usage there are some another advances for some usage namely materials which are resistant to mold fungi and the microorganisms. It is known that the least subject to the fungi effect are things what are consisted as linen fibers among all as well as sulfite and sulfate cellulose. The artificial fibers are more resistant than natural. Obviously the problem of conservation of already printed on paper materials growths more and more every year. Now it is strange when we can’t read old books which have not being saved in new digital formats. That is why the preserve the old paper literature in worthy state is so important for us and for future generations, and the problem of obtaining so called “biocide” material is so actual. It means such material which may destroy bacteria, mold fungi, and insects. In this work we have used the clays from Zakarpatiyan oblast Horbsky field. These clays are classified as bentonite type and have the following consistence with particular size is between 0,3 and 0,25 mm. The authors studied the sorption of latexes by basalt fibers. The following latexes were investigated: divinyl methyl methacrylate (DMMA), divinyl nitrile (SKN), isoprene nitrile (L-7). A method was used to recharge the surface of cellulose fibers to obtain a flexible, durable filter material. We checked the resistance of materials to mold. |
