What's the scan rate?Quentin_alex said:I ran a test on an industrial composite of 30% glass-filled nylon 6, and my melting temperature peak is too low. The range was from -30 C to 275 C. Why could this be happening? Should I suspect the sample pan?
Differential scanning calorimetry (DSC) is a thermal analysis technique used to measure the amount of heat absorbed or released by a substance as it undergoes a physical or chemical change. It is commonly used in materials science to study the thermal properties of polymers, including nylon 6.
DSC works by measuring the temperature difference between a sample and a reference material as they are both heated or cooled at a constant rate. As the sample undergoes a phase transition, such as melting or crystallization, it will either absorb or release heat, causing a change in the temperature difference that is recorded by the DSC instrument.
DSC analysis of nylon 6 can provide information on its thermal properties, such as melting point, glass transition temperature, and heat capacity. It can also be used to study the degree of crystallinity and the presence of any thermal transitions or phase changes in the polymer.
DSC is a non-destructive and relatively quick technique for analyzing the thermal properties of nylon 6. It also requires small sample sizes and can provide quantitative data on the amount of heat absorbed or released during a phase transition. Additionally, DSC can be used to study the effects of additives or processing conditions on the thermal behavior of nylon 6.
One limitation of DSC is that it cannot differentiate between thermal transitions that occur simultaneously, which may be the case for nylon 6 due to its complex thermal behavior. Additionally, DSC results may be affected by factors such as sample preparation and instrument calibration. It is important to carefully interpret DSC data and consider it in conjunction with other analytical techniques for a more comprehensive understanding of the material.
