    Rubber is different from other polymeric materials because it needs to be crosslinked or vulcanised and mixed with several additives like fillers to achieve its state. The recycled rubber materials presented as granules are rapidly used as infill material for different fields. One of the most important issues, especially in Albania is proving that these materials are recycled. One of the most important issues, especially in Albania is proving that these materials are recycled. Through the images provided by SEM we could study the microstructure of our samples. Also, after conducting an EDX spectrum analysis, we observed additives in the recyclable materials. The DSC methods analyses that will provide info regarding the composition in rubber granules. Thermal analysis is an essential technique to measure the temperature or time dependent response of physical and chemical changes that occur in materials.

  • Structure studding of recycling rubber materials through Infrared with ATR, DSC and Scanning electron Microscopy and energy dispersive analysis (SEM)

    Materials Science. Non-Equilibrium Phase Transformations., Vol. 7 (2021), Issue 1, pg(s) 27-30

    Tires are complex objects that consist of many different parts, each with a specific formulation, and include natural or synthetic polymers, carbon black, steel, dispersed oils, dispersed oils, sulfur for the vulcanization or bonding process, organic addit ives and inorganic, and even glass fibers. Their investigation poses a difficulty in identifying them, due to their complex structure. In the Tire
    Recycling Industry we encounter the problem of quality control, which is difficult due to the lack of solubil ity of rubber particles, as well as the limited technical means of these industries. The study aimed to investigate the structure and composition of recycled tires, used in artificial turf / grass as fillers.
    The study focused on the development of standard investigation methods using three instrumental and analytical techniques, as well as the study of morphological changes they have undergone during the recycling process and the impact of additives on them. The aim of this scientific search is studying the structure rubber these materials are recycled, that is one of the most important issues, especially in Albani. Through FT-IR with ATR Analysis, is a analysis technique that provides information about the chemical bonding or molecular structure of materials, Differential Calorimetry DSC and Scanning Electronic microscope (SEM) equipped with the system of
    dispersive of energy spectroscopy (EDS).
