ПримерыExamples
Настоящее изобретение далее объясняется в подробностях ниже с помощью примеров и сравнительных примеров, но изобретение никоим образом не ограничивается этими примерами.The present invention is further explained in detail below using examples and comparative examples, but the invention is in no way limited to these examples.
Смазки были подготовлены путем добавления базового масла и жирной кислоты в реактор, нагреваемый до 85-90oC (со скоростью 3oC/мин), и перемешивания с частотой 100 об./мин. Гидроксид кальция добавляли в виде порошка и затем добавляли воду. Реактор закрывали и нагревали до 135oC (со скоростью 2oC/мин). Содержимое перемешивали с частотой 100 об./мин и предел температуры стенок реактора был задан равным 140oC. Реактор вентилировали на протяжении около 40 минут после достижения 135oC. Дополнительное базовое масло нагревали до 80oC и затем добавляли посредством насоса в реактор. Содержимое перемешивали с частотой 150 об./мин на протяжении 5 минут и температуру продукта поддерживали от 130 до 135oC. Трубу подачи азота присоединяли к реактору, и содержимое подвергали воздействию потока азота в течение 15 минут, тем самым дегидратируя образец. Содержимое охлаждали до 100oC (со скоростью 2oC/мин) с перемешиванием с частотой 100 об./мин. Подмешивали добавки, используя дополнительное базовое масло для разбавления, при температуре 80oC или ниже. После подмешивания добавки содержимое перемешивали в течение 1 минуты с частотой 100 об./мин. Содержимое затем охлаждали до 50-60oC (регулировали заданием температуры стенки: 20oC со скоростью 5oC/мин и перемешиванием с частотой 100 об./мин). Деаэрирование проводили при 70oC, используя вакуум -150 мбар в течение10 минут и перемешивая с частотой 50 об./мин. Продукт гомогенизировали при 1 x 300 бар.Lubricants were prepared by adding a base oil and a fatty acid to a reactor heated to 85-90 ° C (at a speed of 3 ° C / min) and stirring at a frequency of 100 rpm. Calcium hydroxide was added in powder form and then water was added. The reactor was closed and heated to 135 o C (at a rate of 2 o C / min). The contents were stirred at a frequency of 100 rpm and the wall temperature limit of the reactor was set to 140 ° C. The reactor was ventilated for about 40 minutes after reaching 135 ° C. The additional base oil was heated to 80 ° C. and then added to the reactor by pump. The contents were mixed at a frequency of 150 rpm for 5 minutes and the temperature of the product was maintained at 130 to 135 ° C. A nitrogen supply pipe was connected to the reactor, and the contents were exposed to a stream of nitrogen for 15 minutes, thereby dehydrating the sample. The contents were cooled to 100 ° C (at a rate of 2 ° C / min) with stirring at a frequency of 100 rpm. Additives were mixed using additional dilution base oil at a temperature of 80 ° C. or lower. After mixing the additive, the contents were mixed for 1 minute at a frequency of 100 rpm. The contents were then cooled to 50-60 o C (regulated by setting the wall temperature: 20 o C at a speed of 5 o C / min and stirring at a frequency of 100 rpm). Deaeration was carried out at 70 ° C. using a vacuum of -150 mbar for 10 minutes and stirring at a frequency of 50 rpm. The product was homogenized at 1 x 300 bar.
