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.","PeriodicalId":22199,"journal":{"name":"Technical science and innovation","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85054884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":22199,"journal":{"name":"Technical science and innovation","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85647055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
