Study of the influence of gaseous hydrogen and its mixtures with natural gas on typical polymer materials used in gas pipelines through periodic research and comparative analysis of their structure and thermophysical properties.
popup.description2
The aim of the work is to study the effect of gaseous hydrogen and its mixtures with natural gas on typical polymer materials used in gas pipelines by periodic study and comparative analysis of their structure and thermophysical properties.
The aim of the first stage of the work is to conduct laboratory studies of the structure and thermophysical properties of polymer materials before hydrogen exposure in order to indicate further possible changes.
To achieve the aim of the first stage of the work, the following studies were conducted:
• •The thermophysical properties of materials were studied:
- Thermogravimetric analysis of materials was carried out.
- Thermophysical studies of materials were carried out using the differential scanning calorimetry method.
• The structure of materials was studied before their hydrogenation:
- X-ray structural analysis of materials was performed.
- The structure of materials was studied using the infrared spectroscopy method.
The object of the research is changes in the structural organization and thermophysical properties of polymer materials.
The subject of research is the materials of the bushings made of biconite, paronite and fluoroplastic.
Research methods: thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray structural analysis, infrared spectroscopy
