Effect of the duration of homogenization of rubber latex with a coagulating agent on the decrease in aggregative stability

The article examines the effect of the duration of homogenization of rubber latex with coagulating agents on the process of rubber separation. The production of synthetic rubber involves a number of complex chemical and physical processes that can have a significant impact on efficiency and energy consumption. One of the key factors to consider is the thermal effect associated with changes in the internal energy of the system. The paper examines two approaches to the production of rubber: the use of salt as a coagulant and the use of a cationic electrolyte. Studies have shown that when using sodium chloride, coagulation proceeds by a concentration mechanism, and when using N,N-dimethyl-N,N-diallylammonium chloride - by a neutralization mechanism. At the same time, the duration of combining rubber latex with a solution of sodium chloride affects the consumption of the coagulant necessary for the complete separation of rubber from latex. However, when using N,N-dimethyl-N,N-diallylammonium chloride as a coagulant, this effect was not detected. These differences highlight the different coagulation mechanisms depending on the reagent used. The consumption of the cationic electrolyte for the separation of one ton of rubber from latex remained constant. The data obtained are of both scientific and practical importance for optimizing technological schemes and reducing energy consumption.
