Three Factors Affecting the Tensile Test Results of Cigarette Tear Tape

Every kind of Cigarette Tear Tape before the launch of its various properties should be rigorously tested and confirmed. From the experimental point of view, the impact of Cigarette Tear Tape tensile test results are many factors, in addition to internal factors, there are some external factors. Qianghui technology from the operation process, data processing, personnel operations to analyze their three aspects of Cigarette Tear Tape tensile test results.

The influence of the detection process on the tensile testing of Cigarette Tear Tape

In the tensile test on the Cigarette Tear Tape, the tensile speed changes, the mechanical behavior will also change. Under normal circumstances, the tensile rate of fast stress and tensile strength increases, and the elongation at break will be reduced. Because the Cigarette Tear Tape is a viscoelastic material, its force relaxation process is closely related to the deformation speed.

Stress relaxation requires a time course. When the low temperature is stretched, the molecular chain is displaced and rearranged, and the adhesive tape exhibits toughness. The tensile strength decreases and the elongation at break increases. At high speed, Of the movement can not keep up with the speed of external force, Cigarette Tear Tape showed brittle behavior, showing increased tensile strength, elongation at break. Only when the tensile speed is the same, the test data is comparable.

For unfamiliar materials, before the formal test to be predicted to predict the appropriate load and speed, etc., ready for the formal test.

Effect of Data Processing on Tape Tension Testing

Data processing is an important part of the whole test process, and therefore has a close relationship with the accuracy of the test results.

Now most of the material testing machine by the computer control, data processing has been programmed, but some data or rely on artificial testing and calculation. Such as sample size, displacement change, elongation calculation.

Data processing takes the principle of rounding, based on the measurement error, the measured or calculated data is intercepted into the required number of bits, the number of bits to be rounding (or omitted).

Effect of Personnel Operation on Tensile Testing of Cigarette Tear Tape

The whole process of testing is carried out under human operation and control, and human factors inevitably affect the test results. Even if the fine and serious experience of experimental people to do the test, each test data will not be exactly the same. Human factors related to sampling, sample preparation process, sample handling, test process, data processing and so on. Do the comparative test, it is best to operate the same person to ensure that the correct conclusion.

Through the above analysis, from the experimental point of view, the impact of Cigarette Tear Tape tensile test results are many factors, in addition to internal factors, there are test environment, test equipment, sample preparation and processing, operation, data processing, personnel operations factor. Some of these external factors are objective aspects, such as temperature, humidity, etc., some subjective aspects, such as personnel operations, these factors will eventually affect the test results.

It is possible to draw out the same test and test results for the same kind of Cigarette Tear Tape. It is necessary to take into account and strictly control the external factors related to the accuracy of the test data, especially the external factors of the subjective aspects. With comparability, consistency and accuracy. Therefore, the test personnel must have a high sense of responsibility, strict implementation of the test standards and operating procedures, the daily strengthening of the tensile testing machine and other equipment should pay attention to maintenance, operation and self-calibration, to ensure that the experiment is in good condition, in order to obtain accurate test data.
