polyamide 6
heat storage - Opis:
- Phase-change materials (PCMs) have been the subject of numerous studies for many years thanks to their ability to accumulate heat from phase transitions. This group of materials is different to conventional groups, such as metals, polymers or ceramics. A PCM can be any material with specific parameters, such as the temperature of the phase transition suitable for the application, high enthalpy of the transition, easy product availability or a relatively low price. Applications for this type of material are numerous – from construction, where they are used to collect heat for cooling and heating buildings, through water heating, collecting heat from solar panels, creating smart textiles for athletes and people working in changing weather conditions, to planned applications in food packaging to keep food at the right temperature for longer. Corrosion issues with common PCM salts used in a medium temperature range (150–250°C) induced the development of chemically nonaggressive materials. Due to its high availability, satisfactory melting point for use in heat accumulators and relatively low price, polyamide 6 was used in a series of tests. Polymers are not a popular material for PCM due to their low melting enthalpy and fast degradation. Static temperature exposure tests were run and the first cooling curves were examined to determine whether polyamide 6 is a suitable PCM for this application. The results obtained so far are optimistic, but further tests will be required to determine the performance of the material during repeated charging and discharging cycles of the heat accumulator (heating and cooling of the polymer).
