Abstract: A paper-like nanocomposite material based on mineral fibers, which can be used as a capillary-porous element of evaporative-type air-cooling units. The material is made using glass fibers with a diameter of 0.4 ?m as mineral fibers and sodium aluminate and aluminum sulfate as a binder. The material is made on traditional papermaking equipment using casting technique with a specified ratio of the above components.

Abstract: The paper-like nanocomposite material can be used as capillary-porous elements of evaporative-type air-cooling units. As mineral fibers, glass fibers with a diameter of 0.4 ?m are used. These fibers are hydrophilic; they do not swell and have a large specific surface area. As a binder, sodium aluminate and aluminum sulfate are used at a predetermined ratio. The material is made on traditional papermaking equipment using casting technique with a specified ratio of the above components. The technical result is the obtainment of a paper-like material having high properties in height and time of water rise, moisture capacity and strength. The material is also characterized by thermic, chemical and biological stability, absence of toxicity and zero emission of substances harmful to the human body into the air, resistance of its properties to the effects of mold, fungi and microorganisms in the aquatic environment.
