Метод неруйнівного контролю зразка водного розчину адипинової кислоти

Abstract

Purpose. Development of a method of nondestructive control process of electrical and temperature parameters nonmagnetic solutions of chemicals, such as adipic acid, using a contact eddycurrent converter (CEC). Methodology. Used method of determining the dependence of the normalized signal CEC from the physical-mechanical properties of the sample of adipic acid. Finding. The theoretical studies have shown the ability to determine the electrical and thermal parameters of the non-magnetic solutions of chemicals using a hovercraft. Theoretical relationships which connect the electrical parameters CEC with temperature and process parameters nonmagnetic chemical solutions, in particular adipic acid. The results of experimental studies confirmed the possibility and feasibility of the CEC to control the physical-mechanical properties of non-magnetic solutions of chemicals. Originality. Theoretically proved the possibility of CEC for nondestructive process control parameters of the non-magnetic solutions of chemicals, obtained universal conversion function. Practical value. The proposed method of control characteristics of acids and sample solutions allows to evaluate the metrological characteristics of converters, which are based on the sensing of patterns transverse magnetic field, that is to assess the frequency band, as well as ranges of CEC signals that correspond to the range of variation of the electrical and thermal characteristics of the controlled product, materials and media.
