Известен способ определени объемных дефо1р:маЦ1ИЙ влагонасыщеЕных ка пилл 1рнопористых материалов, включающий гид|ростатичеокое .взвешивание образца материала,There is a known method for determining volumetric defoating: maTs1Iy water-saturated capsules of 1-porous materials, including the hydrostatic weighing of a sample of material,
Цель изобретени - определ ть из1м©нейие объемна образца при за мараживании и оттай в аниИ.The purpose of the invention is to determine the bulk of the sample from 1m © during the coating and defrosting in animation.
Достигаетс тем, что исследуемый образец каиилл р1н:онпо(ристого материала увлажи ют и выдерживают в закрытом сосуде в изотермических услови х до ра1виомериого распределени потенциала маооопереноса, попружают последний в жидкость с TeMnepiaтурой , равной температуре и3отер:мичеокой вы/держки образца, затем За1мора1живают образец со акаростью менее 0,2° С/мм по сечению образца и, фимсиру изменение выталкивающей силы, дей;ст1вующей на образец, определ ют его объвмиые деформации.Achieved by examining the sample of the caillil p1n: onpo (the material is moistened and kept in a closed vessel under isothermal conditions until a uniform distribution of the potential of maoooperosis is obtained, the latter is poured into a liquid with a temperature equal to the temperature and the sample: you are using sample samples. with an acarity of less than 0.2 ° C / mm over the cross section of the sample and, to a fimsiru change in the buoyancy force acting on the sample, its combined strains are determined.
Исследуемый образец материала объемом около 1 см увлажн ют до заданного значени потенциала массопереноса в, выдерживают в закрытом сосуде, иагаример в экоикаторе , затем помещают в жидкость, незамерзающую три отрицательных температурах (в пределах .исследуемого тем1перату|рнопо инте (р|вала). Жидкость постепенно охлаждают, что ведет за собой замораживание об разца и изменение ето объе-ма.The sample of material under investigation with a volume of about 1 cm is moistened to a predetermined value of the mass transfer potential, kept in a closed vessel, an agarimeter in an eikikator, then placed in a liquid that does not freeze three negative temperatures (within the temperature range examined | p) shaft (p | shaft). gradually cooled, which leads to the freezing of the sample and the change in this volume.
В предварительных эк спери1ментах подбирают скорость замораживани образца. Фиксируют изменение выталкивающей силы, дейст (вующей на образец, и определ ют изменение его веса, по которому вычисл ют объемные деформации образца.In preliminary experiments, the sample freezing rate is selected. The change in the buoyancy force acting on the sample is recorded, and the change in its weight is determined, from which the volumetric strain of the sample is calculated.
Аналогичным образом о-щредел ют объемные деформации и в процессе оттаивани образца .In a similar manner, volumetric deformations are also determined in the process of sample thawing.
Предмет изобрете и The subject of the invention and
Способ определени объемных деформаций влагонасыщенных капилл рно-пористых материалов, вклюлающий гидростатическое взвешивание образца материала, отличающийс тем, что, с целью определени изменени объема образца при замораживании и оттаивании, его увлажн ют и выдержиюают в закрытом сосуде в изотермических услови х до равномерного расп|ре|делени потенциала маюсопере1носа, погружают в жидкость с температурой , раанюй тем1пер|атуре изоте1рмической выдержки образца, затем замораживают его со скоростью менее 0,2° С/Л1М по сечению образца и, фиксиру из(менение выталкивающей силы, действующей на образец, определ ют его объемные деформации.The method of determining volumetric deformations of moisture-saturated capillary-porous materials, including hydrostatic weighing of a sample of material, characterized in that, in order to determine the change in sample volume during freezing and thawing, it is moistened and kept in a closed vessel under isothermal conditions until uniform decomposition | dividing the potential of the microscope, immersed in a liquid with temperature, the temperature of the sample isothermically exposed, then it is frozen at a rate of less than 0.2 ° С / Л1М across the section a and seating of (Menenius buoyant force acting on the sample volume is determined by its deformation.
