Waste Separation

Разработаны технология и установка для переработки отработанных фильтровальных порошков (ОФП) в кормовые продукты (КП) на масложировых предприятиях после вымораживания подсолнечных масел с целью исключения процесса их окисления. Предложена модернизация ранее разработанной авторами технологии переработки отходов очистки семян подсолнечника (ООСП). Рекомендовано добавление во вторичное масличное сырье (ВМС) из ООСП обезжиренных центрифугированием ОФП. Установлено, что центрифугирование необходимо осуществлять в течение 35 мин при 900 об/мин центрифуги. Определена наибольшая эффективность прессования с экструдированием при добавлении 1–3% обезжиренного фильтровального порошка в ВМС. Установлено максимальное количество обезжиренного фильтровального порошка (10%). Совместная переработка ООСП и ОФП на созданной экспериментальной производственной установке позволила получить КП в соответствии с требованиями нормативных документов на подсолнечный жмых и КП «Подсолнечный» для сельскохозяйственных животных. It has been suggested modernizing the previous technology for recycling of sunflower seed waste, developed by the authors that included waste separation to obtain secondary oily raw materials. A technology and installation has been developed for recycling spent filter powders into fodder products immediately after freezing of sunflower oils at oil and fat plants to exclude the process of their oxidation. It is established that the centrifugation must be carried out for 35 min at 900 rpm of the centrifuge. The greatest efficiency of pressing with extrusion is determined when adding 1–3% of fat-free filter powder to secondary oilseeds. The maximum amount of fat-free filter powder (10%) is set. The co-processing of sunflower seeds waste and spent filter powders at the created experimental operation-performing installation made it possible to produce an experimental fodder product which meets the requirements of normative acts for sunflower seed cake and sunflower fodder product «Podsolnechnyy» used for feeding farm animals.

In this work, the elastic–plastic properties of the printed interconnects on a glass substrate with Ag-filled polymer-conductor ink are evaluated through a theoretical framework based on finite element (FE) modeling of instrumented sharp indentation, experimental indentation, the concept of the representative strain, and dimensional analysis. Besides, the influences of the ink-solvent content and temperature on the elastic–plastic and electrical properties of the printed Ag-based interconnects are also addressed. First of all, parametric FE indentation analyses are carried out over a wide range of elastic–plastic material parameters. These parametric results together with the concept of the representative strain are used via dimensional analysis to constitute a number of dimensionless functions, and further the forward/reverse algorithms. The forward algorithm is used for describing the indentation load–depth relationship and the reverse for predicting the elastic–plastic parameters of the printed Ag-based interconnects. The proposed algorithms are validated through the correct predictions of the plastic properties of three known metals. At last, their surface morphology, microstructure, and elemental composition are experimentally characterized. Results show that the elastic–plastic properties and electrical sheet resistance of the printed Ag-based interconnects increase with the ink-solvent content, mainly due to the increase of carbon element as a result of the increased ink-solvent residue, whereas their elastic–plastic properties and electrical performance decreases with the temperature.
