Description
11 Изобретение относитс к исследованию свойств материалов, а именно к способам определени структурности сажи. Целью изобретени вл етс повышение точности определени структур ности путем исключени вли ни усилий трени между пуансоном и матрицей . Способ осуществл ют следующим образом. .. В матрицу засыпают навеску сажи, масса которой известна. Затем пуансон ввод т в матрицу и сажу сжимают до достижени заданного давлени Р, При достижении этого давлени про-, извод т измерение высоты полученной сажевой таблетки. Затем сажевую таблетку вновь уплотн ют пуансоном при большем давлении Pj и вновь измер ют высоту таблетки. Структурность сажи определ ют с учетом разности ,л Н высот сажевой таблетки при первом и втором измерени х как отношение изменени объема таблетки при изменении давлени от PJ до Pg к массе навески. Пример. Испытьшали навески массой 1,1 г сажи дев ти различных марок (ТГ-10, ПМ-15, ДГ-100 и др.). Использовали пуансон площадью 2,14 см. Давление Р( составл ло 25,5 МПа, давление Pg составл ло 140 Ша. Структурность сажи составила 28-104 мл/100 г дл разных . исследуемых марок сажи.11 The invention relates to the study of the properties of materials, and specifically to methods for determining the structure of soot. The aim of the invention is to improve the accuracy of structural determination by eliminating the influence of friction forces between the punch and the die. The method is carried out as follows. .. Soot, the mass of which is known, is poured into the matrix. The punch is then introduced into the matrix and the carbon black is compressed until a predetermined pressure P is reached. When this pressure is reached, the height of the resulting particulate tablet is measured. The carbon black pellet is then compacted with a punch at a higher pressure Pj and the pellet height is measured again. The soot structure is determined by taking into account the difference, lN of the heights of the soot pellet in the first and second measurements, as the ratio of the change in the volume of the tablet as the pressure changes from PJ to Pg to the weight of the sample. Example. A sample weighing 1.1 g of carbon black from nine different grades (TG-10, PM-15, DG-100, etc.) was tested. A punch with an area of 2.14 cm was used. The pressure P (was 25.5 MPa, the pressure of Pg was 140 Sha. The carbon black structure was 28-104 ml / 100 g for different. Soot grades studied.
