In this research, we developed appropriate algorithms for the formation of the optimal structural composition of production - technological modules (PTM) based on the automation of the processes of determining and ensuring the functional-parametric compatibility (FPC) of their components. These algorithms are based on the developed mathematical models on the basis of the use of analytical methods for implementing the interconnection between the main components of the PTM.

Waste water is generated in almost all industrial enterprises and is contaminated with various organic and inorganic impurities and some heavy metals to varying degrees. The aim of this study is to study the effect of polyhydric alcohols on the current efficiency in the electrochemical method of purification of industrial wastewater contaminated with various heavy metals, in particular chromate ions. The current efficiency of chromium does not exceed 18% during the electrolysis of wastewate, during the process in the presence of xylitol in an amount of 0,16%, the current efficiency increased by 21,9%, in the presence of glycerin in an amount of 0,18%, the current efficiency increased by 23,1%, in the presence of ethylene glycol in the amount of 0,20%, the current efficiency increased by 24,2%

This article is devoted to the use of ammonium sulfate in the production of nitrogen-phosphorus fertilizers, which are widely used in agriculture today. In the research work, the possibilities of obtaining azo superphosphate are described in detail by the use of intensive technology based on low-grade phospharites of the Central KyzylKum. X-ray and IRspectroscopic analyzes of a new type of NP-complex fertilizers obtained using a solution of ammonium sulfate in sulfuric acid are described in detail. The X-ray analysis of the obtained sample on the X-ray diffraction pattern of the azo-superphosphate fertilizer revealed the appearance of peaks in the interplanar spacing line (NH4)2SO4 of ammonium sulfate and NH4Н2РO4 of ammonium dihydrogen phosphate. It has been substantiated that in addition to the main nutrient components dicalcium phosphate and monocalcium phosphates, the sample also contains (NH4)2SO4 and NH4Н2РO4. The results of IR spectroscopic analyzes show that the process of decomposition of the CO3 2-ion in the composition of phosphorites, peaks with high intensity formed by stretching vibrations, in the regions of 873.75 and 1417.68 cm-1, were not detected in the IR spectra of the obtained sample and this proves that that the complete decomposition process is complete. Also, the formation of stretching vibrations of the H2PO4-ion - 1215.15 cm-1, the PO4 3-ion - 532.35 cm-1 and bending vibrations of the H2PO4 -ion - 1033.85 cm-1 in the IR spectrum of the sample in this NH4Н2РO4 sample and the formation of stretching vibrations of SO4 2-ion 1436.97 cm-1 confirmed the presence of (NH4)2SO4.

In this article, the main object of research is the creation of appropriate microclimatic conditions to ensure reliable and high-quality storage of archival documents, as well as automatic control of the optimal values of the main parameters of the external and internal environment that directly affect the quality of storage. To control the microclimate, three categories of models for automatic control of these parameters are considered separately in the archives: the “white box”, “black box” and “gray box " models. The results of the analysis of the advantages and disadvantages of the considered models are presented. The generalized structure of the microclimate management system is also given, as well as a list of controlled and changeable parameters of the microclimate management system of archives. It is proposed to use the fuzzy logic apparatus to create microclimate control systems in archival repositories, which allows synthesizing stable algorithms for its functioning in conditions of uncertainty. The specific steps that need to be performed when designing and using fuzzy inference systems and which are implemented based on the rules of fuzzy logic are listed. When designing and using fuzzy inference systems, it is necessary to observe certain stages that are implemented based on the rules of fuzzy logic. A generalized algorithm for forming a rule base with a technique for implementing the fuzzy inference procedure is presented. The tasks that need to be solved when designing a fuzzy control system are indicated. A system of automatic temperature control in archival repositories with a fuzzy logic controller is presented.

In this research paper, analytical equations of the transient characteristics of a new remote transformer current converter without a compensating capacitor have been obtained when a stepwise, linearly increasing, sinusoidal and sinusoidal with a damped amplitude of effects was applied to their input. It has been shown that the developed current converter can be represented in the structural schemes of monitoring and control systems in the form of a series-connected real ifferentiating link without statism and inertial (aperiodic) link of the first order, and in the case of neglecting active losses in the magnetic circuit and when the converter is operating in idle mode, i.e in the form of ideal differentiating link.It has been established that the transient response of the developed current transducer has an aperiodic character when a surge primary current is fed to its input, and with a relatively very large value of the time constant of the secondary circuit compared to the time constant of the magnetic circuit, transient response approaches transient response of a real differentiating link.

The article studies the process of obtaining carbonate-ammonium nitrate (CAN) based on the mixing of melt ammonium nitrate (NH4NO3) with chalk (СаСО3) and ammonium sulfate (NH4)2SO4). For the granulation of nitrate-sulfate-carbonate melt the prilling method is applied using a granulation tower. Determined the composition and properties of new types of fertilizers. It is shown that with the ratio NH4NO3 : СаСО3 : (NH4)2SO4 = 100 : 24 : 1 the product contains 28,03% N, SO3 – 0,50%, 10% СаО and has a granule strength of 6,03 MPa, which is much higher than the strength of pure NH4NO3 granules (1,32 MPa). Porosity and absorption of pure AN granules is 22,0% and 4,82 g. With an increase in the proportion of chalk and ammonium sulfate to the NH4NO3 : СаСО3 : (NH4)2SO4 = 100 : 24 : 1 ratio, the porosity and absorbency of the LAN granules is 6,11% and 2,57g, respectively. It was revealed that the use of the (NH4)2SO4, СаСО3 additive in the NH4NO3 melt at a mass ratio of NH4NO3 : СаСО3 : (NH4)2SO4 = from 100 : 2 : 0,5 to 100 : 58 : 2 allows to increase the strength and temperature of the onset of decomposition of the nitrate granules by 2-6,7 and 1-1,3 times and reduce the porosity by 2,7-4,8 2 times.

In this article, the forms of moisture connection and the thermal characteristics of plant materials are studied. Rosehip and hawthorn fruits were chosen as the object of research. In the heat analyzer, a decrease in the mass of the product and an increase in temperature were found when the temperature was controlled in a certain gas environment. The curves of the dependence of the dog rose and hawthorn samples on the mass and temperature are given. DTA-1/10 galvanometer sensitivity; sensitivity of the DTG-1/5 galvanometer; the maximum heating temperature is 300° С and the rate of change of the furnace heating temperature is 3° С / min. The temperature features of the process of thermolysis of plant products have been studied. As a result of the study, the initial temperature, the highest and the final temperature of endothermic action were determined.
