🔬 6. Key Scientific Instruments/Techniques:
A universal testing machine measures the mechanical properties of materials by collecting data on resistance force (via a load cell) and displacement (via a displacement measuring device, such as crosshead extension or an extensometer). The results can be displayed in various units (N, kN, kg, g, lb). From the acquired data, a force-displacement curve can be generated. Subsequently, by incorporating the specimen’s dimensions, a stress-strain curve is derived. This curve illustrates crucial mechanical properties of the material, including its Modulus (stiffness), Strength (resistance to deformation), and Elongation (ductility).
This instrument quantifies Adsorbable Organic Halides (AOX) in wastewater, adhering to ISO 11480, ISO 9562, and SCAN-W 9-89 standards. The methodology involves the adsorption of all organic compounds onto activated carbon. Subsequently, inorganic chlorides are removed by washing with a nitrate solution, leaving only organic chloride or halogen compounds. The resulting activated carbon is then subjected to high-temperature combustion, causing the organic compounds to decompose into hydrogen chloride gas and other halogens. These gases are captured by an acid solution. Finally, the total chloride and halogen content is determined via coulometric titration.
Impact testing is a method used to determine the impact energy, impact transition temperature (ITT), and to examine the fracture surface of a material. This is achieved by striking a standardized test specimen until fracture occurs. The primary purpose of conducting this test is to study a material’s capacity to withstand dynamic loads.
A melt flow indexer is an instrument designed to measure both the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) of various thermoplastic materials, typically in pellet form. This instrument is suitable for a wide range of polymers, including but not limited to polystyrene, polyethylene, polypropylene, nylon, acrylate resins, polyoxymethylene (POM), fluoroplastics, and polycarbonate, as well as other plastic materials.
