Jeder kennt EPS, das Verpackungsmaterial, das in der Unterhaltungselektronik für Fernsehgeräte oder Computer sowie für Isolierungen von Gebäuden. eingesetzt wird. Ausgangsbasis für EPS-Teile ist Polystyrol-Granulat, das homogen mit einem Treibmittel – meist Pentan − angereichert wird. Je mehr Treibmittel ein Mikrogranulat enthält, desto leichter lässt es sich im Prozessschritt Vorschäumen expandieren. Um die erforderlichen Verarbeitungsparameter genau bestimmen zu können, ist die Kenntnis des Treibmittelgehalts wichtig. Lesen Sie wie Thermogravimetrie Ihnen dabei hilft!
Thermogravimetry (TGA) is frequently applied for the compositional analyses of such materials as, for example, fiber-reinforced polymer composites. The residual mass at the end of a TGA experiment reflects the filler or glass fiber content as well as the presence of impurities. By using a relatively large sample volume in a top-performing thermobalance along with the intelligent Proteus® software by NETZSCH, it is possible to detect ultra-small residual masses with concentrations down to the ppm (= 10-6) range! Such small concentrations can be illustrated by a little bird with a mass of a few grams sitting on the back of an elephant weighing a few tons.
The University of Queensland, in collaboration with the Non-Conforming Building Products (NCBP) Audit Taskforce in Queensland, Australia, have proposed a framework to provide a robust methodology to assess the fire hazard of cladding materials in existing buildings based on a thorough understanding of the relevant fire phenomena. Thermogravimetric Analysis enhances the robustness of the framework. Read here how the method is applied to evaluate the risk of external fire spread on buildings.
Water is one of the major parts influencing our climate. Our atmosphere is filled with water. We may not always be able to see it, but it interacts with us and our materials. Learn how thermal analysis helps identify water absorption and determine water content.
Identify is the most comprehensive database system in Thermal Analysis! In a nutshell, Identify can be used for the recognition and comparison of measurement curves. Signals of types DSC, TGA, DIL/TMA and cp are supported, curves can be found and overlaid easily. This article highlights the great database contents of Identify (status 11/2019): The Identify database already contains about 2300 database entries!
The database system for thermal analysis by NETZSCH, called Identify, has now (from Proteus® analysis version 8.0 or higher) already more than 2000 database entries available.
Furthermore, Identify can now be used with combined TGA+DSC, TGA-c-DTA® and STA measurements, which allows for material identification with greater certainty.
AutoEvaluation by NETZSCH is a very helpful tool for evaluation of thermoanalytical measurements. The entire measurement is evaluated by AutoEvaluation automatically and autonomously (not via pre-defined macro!) – with only one mouse click – and just within a second. AutoEvaluation is available for DSC, TGA and now also for STA measurements. Furthermore, the adaptability of AutoEvaluation is adressed.
