AbstractAbout AuthorsReferences
The article is devoted to the study of water vapor sorption by materials of mineral wool products of modern production. The definition of the concept of sorption is given, the possibilities of practical application of sorption isotherms in building thermophysics and in the analysis of the porous structure of materials are described. The known methods for determining the sorption of water vapor are given. Separately described exicator method, which is standardized. The results of experimental studies of sorption isotrem by the method of GOST 24816 of 6 different brands of mineral wool products of modern production of two types of fibers – glass and stone, using traditional and alternative types of binder are presented. According to the analysis of the obtained results, the conclusions were made: mineral wool products made of glass fiber have, in general, greater sorption capacity than products made of stone fiber, while products of the same type of fiber with a similar density may have several times different sorption humidity; the grades under study generally have approximately the same specific surface area, but the volumes of meso- and micropores differing several times; sorption of water vapor materials of mineral wool products of modern production is lower than that of mineral wool products, produced more than 10 years ago. These findings should be verified by additional studies, the results of which will be described in the continuation of this article.
