GB T 17393 Thermal Conductivity Analysis of Polymers
The GB/T 17393 standard provides a method for determining the thermal conductivity of polymers under specified conditions. This test is crucial for quality managers, compliance officers, and R&D engineers who need to ensure that polymer products meet specific performance criteria.
This method is particularly important in the chemical testing sector as it helps in understanding how heat flows through different types of polymers used across various industries such as electronics, construction, and automotive. The thermal conductivity of a polymer can significantly impact its performance under extreme conditions, such as high temperatures or low-temperature environments.
The procedure outlined in GB/T 17393 involves the use of a steady-state heat flow method to measure the thermal conductivity of polymers. This approach ensures that the sample is exposed to uniform heating and cooling conditions, allowing for accurate measurement of its thermal properties. The apparatus used includes a precision calorimeter designed specifically for this purpose.
During specimen preparation, it's essential to ensure that the polymer samples are free from contaminants and have been conditioned according to the standard. This may involve drying or soaking the samples in a specified solvent prior to testing. Once prepared, the samples are placed into the apparatus where they undergo steady-state heat flow measurements.
The reported values include both the thermal conductivity and the apparent density of the polymer sample. These data points are critical for understanding the material's behavior under varying temperature conditions. Reporting must adhere strictly to GB/T 17393 specifications, ensuring consistency across different laboratories performing this test.
Understanding the results from GB/T 17393 can help in optimizing manufacturing processes and improving product design. For instance, if a polymer has lower than expected thermal conductivity, manufacturers might consider adding fillers or modifying the molecular structure to enhance performance.
A table summarizing typical results of this analysis is provided below:
| Material | Thermal Conductivity (W/mK) |
|---|---|
| Polyethylene (PE) | 0.35 - 0.42 |
| Nylon 6,6 | 0.28 - 0.37 |
| Polypropylene (PP) | 0.19 - 0.25 |
The range provided reflects variations based on polymer composition and density.
- Specimen Preparation: Ensures accurate results by following strict guidelines to condition the sample.
