At the first stage, we assess the variation of these parameters with a change in the proportion of glass fibers differing in nominal diameter (0.1; 0.25; 0.4; 0.6 μm). One-, two-, three- and four-component samples are obtained in laboratory conditions. The fiber content in the composition varies from 0 to 100 % in 20 % increments. The strength level of all samples obtained is low, does not exceed 1.2 MPa. The possibility of increasing the tensile strength by reducing the proportion of glass fibers with a nominal diameter of 0.6 μm is demonstrated. To obtain maximum strength, the proportion of fibers with a nominal diameter greater than 0.4 μm should not exceed 20 %. We establish a significant correlation between the tensile strength and the capillary rise of glass fiber samples, regardless of their nominal diameter. The maximum increase in tensile strength leads to a 30 % reduction in the separator paper capillary rise. In the second stage, the influence of mercerized pulp additive on the strength and capillary rise of separator paper is studied. We observe a gradual increase in the strength of separator paper when adding mercerized pulp to a glass fiber composition with a nominal diameter of 0.25 μm. For example, a 20 % addition of mercerized pulp leads to an increase in the strength of the samples by a factor of 2 with a drop in capillary rise by 30 %. The increase in strength while maintaining the capillary rise at the required level is possible with the addition of mercerized pulp not more than 10 %. The result of the studies allows us to regulate the fiber furnish to obtain separator paper with the required level of properties necessary for the manufacture of evaporative elements used in air cooling units.AuthorsN.V.
