Water Proofing

One of the main objectives of the project is to develop a methodology for obtaining high quality water-proofing materials. The above- mentioned high-melting tar mass will be used as the main raw material. Especial treatment and further homogenization of the mass – mixture of high-dispersive quartz sand, silicates and other wastes – gives possibility to make various universal and inexpensive compositions. With the aim to improve hydro-insulating and other specific characteristics of the compositions they will be varied by changing the ratio of ingredients. The elasticity of these compositions is conditioned by macromolecular paraffin-ceresin and the polymeric (rubber) components; varying the strength and adhesion is possible by soluble and insoluble silicate-quartz components. The mentioned components can be got in a large amount in region. Therefore, products obtained from cheap raw materials will be inexpensive. The use of the mentioned waste is also important to avoid the pollution of nature. Operating characteristics of the proposed luminophore satisfy requirements of international standarts. In particular, the solutions made from it have an ability to detect invisible cracks of the thick < 1 mm. The light intensity in its greenish-yellow area is 4,5-5 times more than that of standard - uranyl nitrate. It is stable with high quantum efficiency (40-45%).

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

Климатические условия на большей части территории Российской Федерации не позволяют выращивать виноград в открытом грунте, поэтому его завозят из южных районов страны. Производство виноградных напитков обычно сосредоточено в местах выращивания винограда, так как доставка готовой продукции в северные регионы сопряжена со значительными финансовыми затратами. В Республике Дагестан выращивают около 30% винограда в масштабах всей страны, а площадь плодоносящих виноградников занимает более 20 тыс. га. Возникла необходимость переработать виноград таким образом, чтобы полуфабрикат для изготовления напитков выдерживал длительные сроки хранения и транспортировку, отличался высоким качеством и имел небольшую массу. Разработана технология получения виноградных криопорошков, которые можно использовать в качестве пищевых добавок, для изготовления восстановленных соков и напитков. Целью исследования было создание инновационной технологии производства криопорошков для получения безалкогольных напитков. Объектом исследования стал виноград дагестанских технических, столовых и изюмных сортов. Алгоритм получения криопорошков соответствовал предложенной автором схеме: доставка винограда, отделение гребней, инспекция, мойка, дробление, замораживание жидким азотом, обезвоживание в вакуумной СВЧ-установке, криоизмельчение и фасовка. При выполнении работы определяли качественный состав сырья и криопорошков с использованием аналитических приборов и лабораторного оборудования кафедры технологии продуктов питания и учреждений Дагестанского научного Центра РАН. Определен химический состав криопорошков, полученных из винограда, выращенного в горно-долинной зоне Дагестана. Приведены физико-химические показатели напитка из криопорошка винограда. Органолептические показатели изготовленных виноградных напитков подтвердили их высокие качественные показатели. Climatic conditions in most of the Russian Federation do not allow growing grapes in the open field, therefore they are imported from the southern regions of the country. The production of grape drinks is usually concentrated in places where grapes are grown, since the delivery of finished products to the northern regions is associated with significant financial costs. Winegrowers of the Republic of Dagestan grow about 30% of grapes throughout the country, and the area of fruit-bearing vineyards occupies more than 20 thousand hectares. There was a problem to process grapes in such a way that the semi-finished product for the production of drinks withstands long storage and transportation periods, is of high quality and has a small weight. A technology has been developed for producing grape cryopowders, which can be used as food additives, for the production of reconstituted juices and drinks. The aim of the study was to create an innovative technology for the production of cryopowders for the production of soft drinks. The objects of the study were Dagestan common and raisin grapes. The algorithm for obtaining cryopowders corresponded to the scheme proposed by the author: delivery of grapes, separation of ridges, inspection, washing, crushing, freezing with liquid nitrogen, dehydration in a vacuum microwave unit, cryo-grinding and packaging. When performing the work, the qualitative composition of raw materials and cryopowders was determined using analytical instruments and laboratory equipment of the Department of Food Technology and institutions of the Dagestan Scientific Center of the Russian Academy of Sciences. The chemical composition of cryopowders obtained from grapes grown in the mountain-valley zone of Dagestan has been determined. The physical and chemical parameters of a wine drink made from grape cryopowder are given. The organoleptic characteristics of the produced wine drinks confirmed their high quality indicators.

The results of studies of thermolysis waste in the environment of overheated water vapor are presented. It is shown that as a result of fractionation from liquid waste thermolysis products, gasoline and diesel fuel fractions can be obtained. It is proposed to use a composite mixture of liquid and solid waste thermolysis products as raw materials for high-grade technical carbon. Studies have shown that high-grade technical carbon can be obtained as raw materials using a composite mixture of rubber waste thermolysis products as raw materials. The technological line of obtaining technical carbon from the products of thermolysis of worn tires is described. Analysis of the ash produced by the process of burning the composite mixture shows that it contains compounds of iron, zinc and silicon. Therefore, this ash is of interest as a high-quality raw material for the production of zinc oxide, as one of the main ingredients of rubber mixtures.

The aim of this investigation was to develop a treatment for combined porcine blood corpuscle concentrate (BCC) and porcine collagenous connective tissue (rind) so as to make more use of these slaughter by-products as an ingredient in a high-quality product such as salami-type sausage. For this study, BCC was preserved, standardized (sBCC) (15% NaCl and 25% protein content), and then added (proportion of sBCC to rind, 15:85) to rind subjected to different treatments designated A, B, and C (A, 2 h at 90°C; B, 5 min at 90°C; and C, 2 h at 3°C). One half of each mixture was again heated (designated A1, B1, and C1; F70, ∼15), and the other half was only cooled (designated A2, B2, and C2). The now colored, highly proteinaceous rind mixtures (A1 to C2) were then cooled and granulated (designated GBR-A1 to GBR-C2). Three of the granulates (GBRA1, -B1, and -B2) proved to be promising new raw materials: their aerobic plate counts were &lt;log 4.0 CFU/g, and their color was appealing (L* values, 23.9 to 25.9; a* values, 17.7 to 22.2; b* values, 11.5 to 12.7). These granulates were then substituted for part (5%) of the meat in the production of fermented raw salami-type sausages. Two of the sausages (SA1 and SB1) were microbiologically stable (containing mainly lactobacilli) and had positive sensory, chemical, and physical properties (e.g., protein, 21%; water activity, 0.90; pH, between 5.3 and 5.4 on day 36) meeting all standards for commercially produced raw sausages. Our investigation yielded a practicable way to treat and combine two slaughter by-products for use in a high-quality meat product.

Ethnographic examples of stone-tool makers in Australia and archaeological examples from three different areas in the western United States indicate that the availability of lithic raw materials is an important variable conditioning stone-tool production technology. Attributes of availability such as abundance and quality of lithic raw materials condition the production of formal- vs. informal-tool types. Poor-quality raw materials tend to be manufactured into informal-tool designs. High-quality lithic raw materials tend to be manufactured into formal-tool designs when such materials occur in low abundance. When high-quality materials occur in great abundance both formal- and informal-tool designs are manufactured. Other factors, such as residential mobility or sedentism, are found to be less-important determinates of lithic-production technology.

Abstract The article provides information on the main problems of development of dairy enterprises in Ukraine on the criteria of sustainable development and taking into account the vector of the European integration course of the country. The level of providing milk processing enterprises with the quality of raw milk is analyzed. The main trends in the supply of raw milk from agricultural enterprises and households of Ukraine by varieties are presented and analyzed. The dynamics of milk supply and its price are also presented. It is established that the use of quality raw milk directly affects the efficiency of milk processing enterprises. Important aspects of quality control of raw dairy products at enterprises are outlined. High-quality dairy production and reduction of production costs are impossible without the functioning of the raw material quality monitoring system. To this end, it is necessary to introduce the principles of hazard analysis and critical control points in the management structure of dairy companies. It is proved that the key factor of global economic development is the state of the environment, so monitoring the supply of milk - raw materials should also be accompanied by the definition of a set of resource efficiency indicators.

Рассмотрены аппарат уплотнения с частичной химической переработкой сырья и инновационная технология получения гранулированного активированного углеродсодержащего продукта и жидкого биотоплива методом уплотнения (пеллетирования) предварительно измельченного сырья, ускоренного гидролиза, пиролиза, с последующей активацией. Приведены результаты апробации технологии на стендовых установках и аппаратах. Показано, что по- лученные гранулы соответствуют основным показателям отечественных и за- рубежных стандартов на пеллеты из растительного сырья. В процессе произ- водства протекает химическая модификация исходного сырья, на что указывает повышенное значение содержания лигнина в образцах. При проведении пиро- лиза полученных пеллет производятся гранулированный углистый остаток, жидкое биотопливо и горючая парогазовая смесь. Из гранулированного угли- стого остатка получены активированные угли, имеющие адсорбционную активность по йоду, сравнимую с древесным углем марки ДАК. Одним из направлений дальнейших исследований является подбор различных добавок в сырье перед проведением уплотнения и грануляции для улучшения свойств пеллет, в частности повышения теплотворной способности и уменьшения зольности. Однако наиболее интересное направление использования уплотненных отходов растительной биомассы в виде пеллет – в качестве сырья для термохи- мической переработки с целью получения энергетически плотных продуктов, в частности пиролиза. Исследование показало целесообразность разработки единой автономной технологии переработки отходов растительной биомассы с по- лучением конкурентно-способных товарных продуктов: гранулированных активированных углей, жидкого биотоплива, а также парогазовой смеси с достаточной теплотворной способностью для обеспечения работы специальных топочных устройств. The paper deals with the sealing machine with partial chemical processing of raw materials and the innovative technology for obtaining granular activated carbon- containing product and liquid biofuel by the method of compaction (pelletizing) of pre-crushed raw materials, accelerated hydrolysis, pyrolysis and subsequent activation. The results of approbation of the technology on bench installations and devices are presented. It is shown that the obtained pellets correspond to the main indicators of domestic and foreign standards for pellets from vegetable raw materials. In the production process, a chemical modification of the feedstock takes place, as indicat- ed by the increased value of lignin content in the samples. When pyrolysis of the pellets is produced, a granular carbonaceous residue, liquid biofuel, and a combustible gas-vapor mixture are produced. From the granular carbonaceous residue, activated carbons with an adsorption activity of iodine comparable to charcoal of the DAK brand were obtained. One of the directions of further research is the selection of various additives into the raw material before compaction and granulation to improve the properties of pellets, in particular, to increase the calorific value and to reduce ash content. However, the most interesting direction of using compacted biomass res- idue in the form of pellets is to use as a raw material for thermochemical processing in order to obtain energetically dense products, in particular pyrolysis. The work showed the expediency of developing a single autonomous technology for plant biomass residues processing with the production of competitive commodity products: granular activated carbons, liquid biofuel, as well as steam-gas sweep with sufficient calorific value to ensure the operation of special combustion devices.

A study into the failure causes of mixing and charging equipment confirms that the main impact on the probability of accidents is the use of raw materials that do not meet the specifications and have unstable properties. The raw materials used for explosives preparation in mechanized charging of boreholes include such components as ammonium nitrate, emulsion phase, diesel fuel, emulsifier and others. The paper describes the application of various formulations with these components in specific types of mixing and charging machines manufactured by AZOTTECH LLC. The main properties that affect the quality of raw materials are summarised, and the incoming inspection of explosive components is described as part of the acceptance procedure at temporary storage sites at a hazardous production facility. The paper describes common types of equipment failures and maintenance procedures when using substandard raw materials. The conclusion highlights the key practices to improve the equipment uptime as well as recommendations for incoming inspection and the use of high-quality explosive components.

Common Problems

Long route and high inclusion content are two common problems existing in the present process for magnesium alloys. To solve these problems, a new process technology, in which the crystalline magnesium is used as the raw material, is developed. The process is melting flux→ adding raw materials in batches → stirring→ holding→ pouring (MASHP). The mechanisms of protection and purification mechanisms are also analyzed. The results show that the MASHP process has high protection and purification effects on magnesium alloys. By the in-batches addition mode of raw materials, no oxidation and evaporation loss of magnesium produce during heating and melting, and the inclusions that self-contained in the crystalline magnesium and that produced by oxidation during heating and melting can be minimized. High quality magnesium alloys can be produced by the new process.
