КАРБАМИД ГРАНУЛАЛАРИНИ ТЕРМИК ФАОЛЛАШТИРИЛГАН ДОЛОМИТ БИЛАН МОДИФИКАЦИЯЛАШ: ХОССАЛАРНИНГ ТАРКИБ ВА КУЙДИРИШ ҲАРОРАТИГА БОҒЛИҚЛИГИ

The paper presents the results of producing a slow-dissolving magnesium-bearing modified urea by introducing thermally activated dolomite into the urea melt. Sixty compositions were studied under a two-factor full factorial design; granule dissolution time, melt crystallisation temperature, hygroscopic point, porosity and crushing strength were determined, their dependence on the dolomite fraction and the calcination temperature was described by regression equations, and the optimal regime was substantiated.
