Modelling systems of signalling puncture by chemicals with the use of microencapsulation

Project manager: Rafał Hrynyk M.Sc. (Eng.)

Project summary:

The task consisted in selecting chemical substances for which the efficiency of the system of signalling puncture of protective gloves by chemicals was assessed. Then, principles were established for selecting indicator dyes that were characterized by an intensive change in colour when in contact with those substances.Polymer carriers - in the form of microcapsules that enclosed indicator dyes - were developed. Infrared spectrophotomery was used to characterize the developed structures.The next stage of the task focused on integrating the developed microcapsules with the materials used in producing all-rubber protective gloves. To produce model solutions for gloves integrated with the microcapsules with indicator dyes, two techniques were used: spraying microcapsules onto the form between the consecutive stages of dipping, and dissolving the microcapsules in dispersion used in one of the cycles of dipping the ceramic form. The materials used in developing the model construction of the gloves were natural latex rubber, polyacrylonitrile rubber and polyethylene.
