Способ контроля стадии поликонденсации в производстве алкидных лаков, включающий использование измерений электрофизических параметров реакционной массы, ОТЛИЧАЮЩИЙСЯ тем, что контроль стадии поликонденсации осуществляют посредством непрерывного во времени измерения текущей величины активного сопротивления Rp реакционной массы и тангенса угла диэлектрических потерь tgδ реакционной массы, при этом, параллельно, с интервалом 0,5 часа, проводят отбор проб реакционной массы и их лабораторный анализ, в момент отбора проб замеряют величины Rp и tgδ реакционной массы, по результатам измерений и лабораторных анализов строят графики зависимости между результатами измерений и определёнными значениями вязкости реакционной массы, и используют полученные зависимости значений Rp и tgδ и вязкости для контроля стадии поликонденсации в производстве алкидных лаков, при этом, достижение значений Rp и tgδ, при которых величина вязкости реакционной массы соответствует величине, требуемой регламентом, служит сигналом завершения стадии поликонденсации. The method of controlling the polycondensation stage in the production of alkyd varnishes, including the use of measurements of the electrophysical parameters of the reaction mass, DIFFERENT in that the control of the polycondensation stage is carried out by measuring the current resistance value R p of the reaction mass and the dielectric loss tangent tangent of the mass, while parallel, with an interval of 0.5 hours, sampling of the reaction mass and their laboratory analysis are carried out, at the time of sampling the values are measured R p and tgδ of the reaction mass, according to the results of measurements and laboratory analyzes, build graphs of the relationship between the measurement results and certain viscosity values of the reaction mass, and use the obtained dependences of the R p and tgδ values and viscosity to control the polycondensation stage in the production of alkyd varnishes, while achieving the values of R p and tgδ, at which the viscosity of the reaction mass corresponds to the value required by the regulations, serves as a signal to complete the polycondensation stage.
