Производитс повторное измерение электрического сопротивлени на участке унлотнени сажн Экспериментально доказано, что комкование сажп происходит npsi давлении, характеризуюи1емс отношепmolds at the soot compaction site, after which the punch is lowered to its original position. Repeated measurement of electrical resistance at the site of carbonation is carried out. It has been experimentally proved that the clumping of soot occurs npsi pressure, characterized by the ratio

Пример. Образцы гранулированной сажп ПМ-50 разного качества гранул ции исследовались при начальном давлении пуансона 0,08 кг/см с последовательным увеличением давлени на 0,02 кг/см.Example. Samples of granulated sajp PM-50 of different granulation quality were studied at an initial punch pressure of 0.08 kg / cm with a successive increase in pressure by 0.02 kg / cm.
Пуансон удерживалс в положении сжати в течение 10 с. За это врем производилось измерение сопротпвлени сж, пуансон опускалс , сажа под действием силы т жести увлекалась из участка уплотнени за пуансоном, производилось повторное измерение сопротивлени св, результаты сравнивались, после чего давление увеличивалось на 0,02 кг/см и цикл измерений повтор лс .The punch was held in the squeeze position for 10 s. During this time, the junction resistance was measured, the punch was lowered, soot under the force of gravity was carried away from the compaction area behind the punch, the resistance measurement was repeated, the results were compared, the pressure was increased by 0.02 kg / cm and the measurement cycle was repeated.
