Известны способы определени качества резип путем деформации образца в рабочей среде при заданной температуре и фиксировани времени до его растрескивани .Methods are known for determining the quality of a resip by deforming a sample in a working medium at a given temperature and fixing the time until its cracking.
Известный способ требует длительного времени проведени эксперимента.The known method requires a long time experiment.
С целью сокращени времени эксперимента по предлагаемому способу одновременно измер ют скорость изменени твердости образца , а также образец подвергают истиранию .In order to reduce the time of the experiment according to the proposed method, the rate of change of the sample hardness is simultaneously measured, and the sample is subjected to abrasion.
Кроме того, испытание провод т при температуре выше эксплуатационной.In addition, the test is carried out at a temperature above operating.
Предлагаемый способ заключаетс в следующем .The proposed method is as follows.
Испытываемый образец резины истирают индентором в рабочей среде, например масле, при температуре выще эксплуатационной, измер периодически скорость изменени твердости в поверхностном слое образца с начала эксперимента и врем до его растрескивани .A test rubber sample is abraded by an indenter in a working medium, such as oil, at a temperature higher than operational, periodically measuring the rate of change of hardness in the surface layer of the sample from the beginning of the experiment and the time to cracking.
Дл определени растрескивани при температуре эксплуатации измер ют скорость изменени твердости при этой температуре. По полученным данным вычисл ют врем до растрескивани в услови х эксплуатации.To determine cracking at the operating temperature, the rate of change of hardness at this temperature is measured. From the data obtained, the time to cracking under conditions of operation is calculated.
Предлагаемый способ позвол ет сократить врем получени данных о растрескивании резин в несколько раз.The proposed method makes it possible to shorten the time for obtaining data on rubber cracking several times.
