FIELD: electrical engineering.
SUBSTANCE: method for porous material treatment involves such porous material preliminary impregnation with an auxiliary liquid, insoluble in the impregnation liquid and having a boiling temperature lower than that of the impregnation liquid, the porous material immersion into the impregnation liquid, the porous material, prior to immersion into the impregnation liquid, having been subjected to contact drying under atmospheric pressure.
EFFECT: enhanced efficiency of porous material treatment through an accelerated treatment process and increased impregnation degree; porous material treatment technology simplification.
