As an important tool in the field of materials science, the stability and accuracy of the performance of film biaxial stretching apparatus are directly related to the reliability of the test results. Therefore, daily maintenance and care work is particularly important.

The outer casing of the instrument should be cleaned regularly to prevent dust and dirt from accumulating. You can use a soft cloth dipped in a small amount of neutral detergent to gently wipe it, but be sure to avoid the detergent from entering the inside of the instrument to avoid damaging the internal electronic components. The fixture and sensor are key components of the film stretching instrument, and their cleanliness directly affects the accuracy of the test results. Therefore, after each use, the fixture and sensor should be wiped with a clean soft cloth in time to remove residual samples and dirt. For stubborn stains, an appropriate amount of alcohol can be used for cleaning.

Moving parts such as guide rails, lead screws, etc. should be lubricated regularly. You can use an appropriate amount of lubricating oil or grease to apply to the moving parts to reduce friction and wear. The lubrication frequency is generally once every three months, or adjusted as appropriate according to actual use. At the same time, the fasteners of the instrument, such as screws and nuts, should be checked regularly to ensure that they are fastened reliably to avoid looseness that affects the normal operation of the instrument.

Regular calibration is a key step to ensure the accuracy of the test results. It is generally recommended to calibrate once every three months or after replacing the sensor. Standard specimens should be used for calibration and the steps in the instrument manual should be followed. The instrument should be placed in a constant temperature and humidity environment to avoid the effects of high temperature and high humidity on the performance of the instrument. The room temperature should be maintained at 20-25 degrees Celsius, and the relative humidity should be controlled at 40%-60%.

In addition, the operator should strictly follow the steps in the instrument manual to avoid damage to the instrument or inaccurate test results due to misoperation. Before testing, the purity and size of the sample should be ensured to meet the requirements to avoid the influence of impurities and dimensional errors on the test results. At the same time, the appropriate fixture and test method should be selected according to the nature of the sample to obtain the best test results.

In summary, the daily maintenance and care of the film biaxial stretching apparatus includes cleaning, lubrication, calibration, environmental control, and standardized operation. Only by doing these tasks well can we ensure the accuracy and stability of the instrument and provide reliable data support for materials science research.
