FIELD: study of properties of porous materials. SUBSTANCE: specimen of porous material is extracted and dried. Dried specimen is submerged in kerosene and saturated with kerosene. Mass of specimen saturated with kerosene is found in air and mass of same specimen is determined in kerosene. Specimen is submerged in distilled water for capillary impregnation and holding in this medium in the course of 20.0 h. Mass of specimen in this medium is determined after capillary impregnation. Then this specimen is centrifuged in distilled water in the course of 30.0 min. Mass of specimen in distilled water is established after centrifugation. Amount of water kept in specimen as result of capillary impregnation is computed on basis of previously determined masses of specimen under various conditions and total amount of water entered into specimen as result of capillary impregnation and centrifugation in water is found. Wettability of specimen of porous material is evaluated by relationship of established amounts. EFFECT: increased accuracy and authenticity independent of subjective factors and centrifugation conditions due to use of stable, time invariable parameters with simultaneous expansion of application field of procedure. 1 cl
