Thermal behavior of paraffin wax by sample observation DSC

TA-1036: Thermal behavior of paraffin wax by sample observation DSC

 

Introduction

Phase change material or PCM is a material that can absorb, store and release large amounts of latent heat within a specific temperature range during phase transition reaction. Several materials have been identified as a latent heat storage medium and are classified as organic PCMs, eutectics, inorganic PCMs and clathrate hydrate. Paraffin is an alkane organic PCM, effective for latent heat storage medium via their melting transition and is recently studied in different applications such as solar thermal storage, air-conditioning buildings, integration with fabrics intended for special environmental conditions and others. In this application, sample observation DSC was performed to evaluate the thermal behavior of paraffin wax.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).

 

 

DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.

Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.

TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.

 

The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.

 

TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.

In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
