The data recording function of the film biaxial stretching apparatus is outstanding in terms of completeness and can capture various key parameters during the test. From the beginning of stretching to the whole process of film rupture, the equipment will continuously record core data such as stretching force, deformation degree, stretching rate, etc., and also include auxiliary information such as test time and ambient temperature. These data do not exist in isolation, but form a continuous dynamic record in chronological order, fully presenting the entire mechanical behavior process of the film from elastic deformation to plastic deformation until the final rupture. This comprehensive recording method allows operators to trace back every detail of the test to avoid affecting the judgment of film performance due to the lack of key data.
Its diverse analysis functions can meet the testing needs in different scenarios. For the recorded raw data, the built-in analysis module of the equipment can automatically generate stress-strain curves to intuitively reflect the mechanical properties of the film; at the same time, it can also deeply analyze the curves, extract characteristic values such as yield strength and elongation at break, and provide quantitative basis for material performance evaluation. In addition, the analysis function also supports the comparison of multiple groups of test data. By superimposing curves, differential analysis and other methods, the differences in film performance under different batches or different process conditions can be clearly presented. This diversity allows the equipment to not only complete basic tests, but also meet the analysis needs of complex scenarios such as material research and development and quality control.
The linkage between data recording and analysis functions further enhances its comprehensiveness. During the test, the equipment will synchronously transmit the real-time recorded data to the analysis system. Once abnormal data (such as sudden force value changes) is found, the analysis module will automatically mark and trigger prompts, which is convenient for operators to troubleshoot problems in a timely manner. After the test, the analysis system can directly call the complete recorded data for in-depth processing without manual secondary entry, reducing errors in the data transmission process. This real-time linkage allows data recording and analysis to form a closed loop, which not only ensures the accuracy of the data, but also improves the analysis efficiency and makes the entire test process smoother.
For data traceability, the functional design of the film biaxial stretching apparatus is also relatively complete. Each set of test data will be automatically associated with a unique test number, which is bound to metadata such as sample information and test parameters to form a complete test file. Through number retrieval, operators can access the record data and analysis reports of historical tests at any time, and clearly view the test conditions and results at that time. This traceability is particularly important in quality control. When abnormal material performance is found later, the source of the problem can be traced back to the historical data to provide a reliable basis for process improvement.
Its analysis function also has a certain degree of scalability and can adapt to the ever-changing testing needs. With the deepening of material research and development, the requirements for data analysis may continue to upgrade. The equipment supports the addition of new analysis algorithms or indicator calculation functions through software updates or module expansions. For example, the fatigue resistance analysis of special films can be achieved by adding an analysis module for cyclic stretching data. This scalability allows the data analysis function of the equipment to not be limited to the initial state, and it can be continuously improved as the application scenarios expand, maintaining long-term applicability.
The flexibility of the data recording and analysis function in the presentation method also reflects its comprehensiveness. The analysis results can be displayed intuitively in the form of charts, which is convenient for quickly grasping the overall trend; it can also generate detailed text reports, systematically sorting out the test purpose, process, results and conclusions, and meeting the needs of formal document output. At the same time, the results also support export in multiple formats, which are compatible with commonly used office software and data analysis tools, making it convenient for operators to perform secondary processing or sharing. This flexible presentation method allows personnel in different positions (such as R&D personnel, quality inspection personnel) to easily use the analysis results, improving the efficiency of data utilization.
In terms of meeting industry standards, the comprehensiveness of data recording and analysis functions is also fully reflected. The recording parameters and analysis indicators of the equipment are in line with relevant industry specifications to ensure that the test data can be widely recognized by the industry. For example, in the test of food packaging film, the migration-related data and analysis methods recorded strictly follow the food safety standards; in the test of industrial thin films, the analysis of strength and toughness also complies with the general specifications of material mechanics. This standard-compliant design makes the data recording and analysis results of the equipment authoritative and comparable, and can meet the normative requirements of different industries for test data.
