description: The theme of the final qualification work: âThe impact of variable temperature-humidity on thermophysical and mechanical properties of polyisocyanurate foamâ. The work is devoted to determining the changes in the physicomechanical characteristics of thermal insulation from polyisocyanurate foam under the influence of temperature and humidity over time.
Tasks that were solved during the study:
1. An analysis of the literature on the study of insulation based on polyisocyanurate foam.
2. Conducting experimental studies of PIR panels.
3. Processing of experimental data, comparative analysis by the method of hierarchy analysis.
4. Development of recommendations for the use of thermal insulation from PIR panels.
An experimental study on testing samples of thermal insulation based on polyisocyanurate foam was carried out in an accredited testing laboratory (Research Laboratory "Vysota", Peter the Great St. Petersburg Polytechnic University) in the period 2018-2020. The experiments were carried out in accordance with approved methods using certified equipment.
The aim of the work is to select the optimal insulation according to several criteria, taking into account the change in characteristics over time.
