THE RESULTS OF THE STUDY OF CHANGES IN THE COLOR CHARACTERISTICS OF POLYMERS UNDER THERMAL EXPOSURE
(pp. 40-47)

Abstract. The article presents the results of studies of polymer samples (PVC) under thermal exposure in a muffle furnace, by measuring color characteristics using a model of color decomposition into RGB components. Under thermal action, chemical and physical changes occur in polymers. The degree of thermal damage depends on the time and temperature of exposure [1]. The aim of the work was to establish the dependence of color characteristics in the RGB system on the temperature and time of exposure to PVC samples. A criterion for controlling the degree of thermal damage and a device for implementing the method are proposed. The device is based on the TCS3472 color sensor and a programmable logic controller. The data obtained can be used in the investigation of fires at objects with polymer finishes when detecting fire propagation paths, as well as monitoring the degree of thermal damage to polymers during various technological processes.

Keywords: RGB, color characteristics, degree of thermal damage to PVC.
