Изучение контроля объемной плотности заряда при товарно-транспортных операциях

В процессе исследования проводились расчеты предельно допустимого значения плотности заряда.Расчет максимальной безопасной скорости движения жидкостей по трубопроводу.Расчет длины и диаметра релаксационного участка. Приведены материалы по охране труда и безопасности строительства, охраны окружающей среды, технико-экономическая часть В результате исследования был произведен сравнительный анализ среди способов нейтрализации статического электричества. На основании анализа результатов было выявлено, что применение нейтрализатора статического электричества имеет ряд преимуществ, одним из которых является увеличение срока эксплуатации.In the course of the study, the maximum allowable charge density was calculated; Calculation of the maximum safe rate of movement of liquids through the pipeline; Calculation of the length and diameter of the relaxation section. Materials on labor protection and safety of construction, environmental protection, technical and economic part are given. As a result of the research, a comparative analysis was carried out among methods of neutralizing static electricity. Based on the analysis of the results, it was found that the use of the static neutralizer has several advantages, one of which is an increase in the service life

Study of foam concrete with products of processing of ash and slag materials of seversk chp plant

The results of studies of modified foam concrete with products of processing of ash and slag materials are given in this article. The use of ash and slag as raw material in the production of basic building materials leads to reduction of 15-30 % their prime cost. The goal was to study the efficiency of the aluminosilicate microspheres from ashes and slag mixtures of Seversk CHP plant in foam concrete technology. The optimal composition for the production of effective foam concrete is the aluminosilicate microspheres in an amount of 10 % by weight of cement

Влияние исходной термической обработки на особенности ультрамелкозернистой структуры, сформированной в стали 06МБФ методом кручения под давлением

A homogeneity of strength properties (microhardness) through the specimens and the peculiarities of an ultrafine-grained structure produced in low-carbon steel Fe-Mo-Nb-V-C by cold high-pressure torsion were studied depending on initial heat treatment of steel. As a result of high-pressure torsion, the microhardness of steel was increased up to 6,0-7,7 GPa (in the middle part of disk radii), and the mean (sub)grain size was reduced to ?91-100 nm
