Abstract

  There is little doubt that the main therapeutic action of the peloid’s, therapy depends on their thermal properties. For this reason is quite of interest getting to know the thermal properties of the materials that form peloids.
Objective: Study the thermal properties of three inorganic solids that can be used in the preparation of therapeutic peloids.
Materials and Method: The products used are aluminic Bentonite, Kerolita (Süd Chemie) and SPLF ELITE (Tolsa).
  From the thermal point of view the specific heat was determined using a Scanning Calorimetry equipment, model DSC1, cooled by air of Mettler Toledo and it was used the software STARe for the collection and processing of data.
  An extemporaneous product was prepared with a liquid phase of 60%, using distilled deionized water. Its cooling curves their relaxation and inertia times were studied.
  For the determination of the cooling curves we have followed the Rambaud technique, obtaining graphs and equations that best fit the experimental curve, using the ORIGIN program 8. We used Thermostatic baths, models Lauda RA Alpha 8 and E-100 and a thermocouple Cole-Parmer, model 91100-50.
Results and Discussion: The following Table 1 shows the results of the specific heat measures of the three studied products, in the range of 45-36°C and its corresponding average value. We also include the inertia and relaxation time of peloids.
Conclusions: The SPLF, a sepiolite, presents the highest value of the specific heat, whose corresponding peloid with an equal percentage of water would provide the greatest amount of heat. The specific heat of the bentonite and kerolita is very similar.
  Bentonite Al shows the most relaxation time of the three products, releasing therefore the heat more slowly.
