Изобретение может быть использовано в силикатной промышленности дл контрол качества продукции.The invention can be used in the silicate industry to control product quality.
Известен способ определени химической стойкости материала по изменению механической характеристики образцов в результате воздействи на них химического реактива .There is a method for determining the chemical resistance of a material by changing the mechanical characteristics of the samples as a result of exposure to a chemical reagent.
Цель изобретени - повышение точности определени химической стойкости материала .The purpose of the invention is to improve the accuracy of determining the chemical resistance of the material.
Это достигаетс тем, что химическую стойкость определ ют по изменению величины ударной в зкости образца.This is achieved in that the chemical resistance is determined by the change in the magnitude of the impact strength of the sample.
Суш,ность способа заключаетс в следующем .The dryness of the method is as follows.
Берут не менее 10 шт. образцов, имеющих форму пластин пр моугольного сечени .Take at least 10 pcs. samples having the form of plates of rectangular cross section.
Затем образцы дел т на контрольную и испытуемую партии по 5 шт. в каждой.Then the samples are divided into control and test batches of 5 pcs. in each.
Известным способом определ ют среднее значение ударной в зкости у контрольной партии образцов, а испытуемую часть партии образцов подвергают воздействию химического реактива, затем промывают, высушивают до посто нной массы и испытывают на ударную в зкость.The mean value of toughness of the control sample batch is determined by a known method, and the tested part of the sample batch is exposed to a chemical reagent, then washed, dried to a constant mass and tested for impact strength.
По разности средней ударной в зкости, определенной на испытанных и контрольных образцах, суд т о химической стойкости материала .The difference in average impact toughness determined on tested and control samples is judged on the chemical resistance of the material.
Промывка и просушка не измен ют ударной в зкости.Washing and drying do not alter the toughness.
Описываемым способом можно определить химическую стойкость не только пористых, но и плотных материалов, перевод их известными способами в пористое состо ние.By the described method it is possible to determine the chemical resistance of not only porous, but also dense materials, transferring them to porous state using known methods.
Предмет изобретени Subject invention
Способ определени химической стойкости материала по изменению механической характеристики образцов в результате воздействи на них химического реактива, отличающийс тем, что, с целью повышени точности , химическую стойкость определ ют по изменению величины ударной в зкости образца .The method of determining the chemical resistance of a material by changing the mechanical characteristics of the samples as a result of exposure to a chemical reagent, characterized in that, in order to improve accuracy, chemical resistance is determined by changing the value of the specimen toughness.
