IMPROVING TEACHER EDUCATION IN THE SUBJECT OF LABOR PROTECTION. SONOLUMINESCENT SPECTROSCOPY IN THE SAFETY CONTROL OF TECHNICAL SYSTEMS

Abstract

Improving engineering teacher education in the subject of labor protection is important for the success of the industry. The most important area of labor protection is automated control of the safety of technical systems. The use of sonoluminesce spectroscopy in the safety control of vacuum evaporators was studied. The safety of which depends on the thermo physical properties of brines. Thermo physical properties of brines depend on the concentration of the main substance - sodium chloride and impurities of calcium and magnesium salts. Sonoluminescent spectroscopy is used for automated control of the content of the basic substance and impurities of calcium and magnesium salts. It is shown that the simultaneous action of ultrasound initiation of high and low frequencies sonoluminescence allows a 5-10-fold increase in the value of the analytical signal for calcium and magnesium in brines and its content in accordance with the metrological characteristics required in the salt industry. An automated safety control system for vacuum evaporators was developed and tested in laboratory conditions.
