INVESTIGATION PROCESS OF THERMAL DECOMPOSITION OF VULCANIZATION ACCELERATORS IN A MIXTURE WITH IRON POWDER
To identify the most suitable substance as impregnator studies were carried out mass change TG and enthalpy DTA. Method of physical-chemical research derivotografiya considers these indicators simultaneously. The experiment was performed in the heating mode at 10 degrees per minute starting from room temperature up to 800 ° C. Were considered such substances from the class of porophore as tetramethylthiuramdisulphide and dithiodimorpholine. Graphs of thermal decomposition of pure substance and mixture of iron were analyzed. It's shown the effect of iron on the decomposition of the blowing agent. As a result of pure chemicals heating to 800 ° C, perfect combustion agent without precipitation occur. At 180 ° C the decomposition reaction starts substances to produce gases. At heating a mixture of iron markedly occurs change in graph, that testifies to a substance reaction with iron. To determine the most effectively influencing the quality of processing should be carried out experimental research using the circles impregnated these substances.
