【 摘 要 】

In this paper, the thermal decomposition (pyrolysis) of components of medical waste that consist of polyvinyl chloride (medical oilcloth and tubes of blood transfusion systems) is investigated. Thermogravimetric analyzes were performed in the TG-DTG mode on the synchronous thermal analysis device NETZSCH STA 449 F3 Jupiter. Based on the data obtained, the calculation of the kinetic parameters of the process of thermal decomposition of the investigated samples of medical waste was performed. For tubes of blood transfusion systems, experiments were conducted to absorb gases entering from the reaction volume in order to determine the temperature range of hydrogen chloride emission.
