Description
Изобретение oTHOcjiTCH к контрол й качества нефтепродуктов и может найти применение в химической и нефтехимической страст х промышленное 1. ,... . . -, The invention of technology to control the quality of petroleum products and can find application in the chemical and petrochemical passions of industrial 1., .... . -,
Известен способ опрб делени тем- ; нературы разм гчени по кольцу и (КиШ): кольцо с внутренним дигинетром 15,9 мм и высотой 6,35 мм заливают жидким битумом и ; после охлаждени помещают в вод ную баню, сверху на битум кладут стальной шарик весом 3,5 г и диаметром 9j5 мм; по мере нагрева со скоростью 5 град/мин шарик проходит через об-раэец битума и касаетс дна; за температуру разм гчени битума принимают температуру, при которой бИтуМ переходит в капельно-текучее состо ние в услови х, предусмотренных методикой определени 1.The known method oprb division tem-; ring softening areas and (Kish): a ring with internal digetrom 15.9 mm and height of 6.35 mm is poured with liquid bitumen and; after cooling, they are placed in a water bath, a steel ball weighing 3.5 g and 9j5 mm in diameter is placed on the bitumen; as it heats up at a rate of 5 degrees / min, the ball passes through the bitumen material and touches the bottom; the softening temperature of bitumen is taken as the temperature at which the BITUM enters the drip-fluid state under the conditions stipulated by the method of determination 1.
Недостатками способа вл етс необходимость приготовлени специального образца и необходимость программировани нагрева.The disadvantages of the method are the need to prepare a special sample and the need to program the heating.
Наиболее близким к предлагаемому вл етс способ определени температуры разм гчени битума при стадно- парном тепловом режиме. К аппарату, . :в котором проводитс окисление битума , подключают дифманометр и определ ют вес столба жидкости. Изменение веса столба жидкости свидетельствует об изменении плотности, т. е. об изменении температуры разМ гчеНи 2},Closest to the present invention is a method for determining the softening temperature of bitumen in a herd-steam thermal mode. To apparatus,. In which bitumen is oxidized, a differential pressure meter is connected and the weight of the liquid column is determined. A change in the weight of a liquid column indicates a change in density, i.e., a change in temperature razMHcheNi 2},
Способ имеет следующие недостатки: погрешность вследствие измене .ни плотности при переходе с одного The method has the following disadvantages: the error due to the change in the density on the transition from one
to вида сырь на другой, применимость только в случае большой высоты сло окисл емого продукта, ограниченность точности вследствие погрешности определени веса столба жидкости.to the type of raw material to another, applicability only in the case of a large height of the layer of oxidizable product, limited accuracy due to the error in determining the weight of the liquid column.

Цель изо,бретенн - повышение точности определени температуры разм гчени битума И расширение диапазона составов контролируемого сырь . Поставленна цель достигаетс тем, The purpose of iso, breton is to improve the accuracy of determination of the softening temperature of bitumen And the expansion of the range of compositions of controlled raw materials. The goal is achieved by
20 что поддерживают битумную массу при заданной температуре выше температуру разм гчени , создёиот внутри битумной массы зону охлаждени с температурой поверхности О - 10°С, фикси25 руют температуру битума на рассто нии 0,5 - 1,5 мм от этой поверхности и по полученным данным суд т о температуре разм гчени .20 that the bitumen mass is maintained at a given temperature above the softening temperature, creating a cooling zone inside the bitumen mass with a surface temperature of 0 - 10 ° C, fixing the temperature of the bitumen at a distance of 0.5 - 1.5 mm from this surface and according to the data obtained judge softening temperature.
