STUDY OF THE TECHNOLOGY FOR THE PRODUCTION OF INDIVIDUAL URINE-FORMALDEHYDE COMPOUNDS OF MULTIFUNCTIONAL ACTION ON THE BASIS OF UFC AND ZINC ACETATE IN SPRAY DRYER
Keywords:
urea formaldehyde compounds, zinc acetate, drugs of multifunctional action, drying process, phase composition changes, spray, polycondensation processAbstract
This article presents studies of the process of obtaining low-molecular urea-formaldehyde compounds, drugs of multifunctional action on the basis of lowmolecular urea-formaldehyde compounds and zinc acetate in a spray dryer. Optimum technological parameters of their production are determined. The temperature of the heat carrier is 250-30 оС, the temperature in the reaction zone is 70-90 оС, the moisture content of the obtained products is 1-4%.
