Sponge foam rebound tester Falling ball rebound test method

Sponge Coefficient of Resilience Tester is a kind of equipment used to measure the falling ball resilience of flexible polyurethane foam. It is designed and manufactured according to GB/T6670-2008, meets ASTM D3574 and ISO8307 test standards, and meets Japanese test method SESN3296 for urethane foam for automobile seat cushions. The instrument is used to calculate the percentage of the ratio of the maximum height of the steel ball rebound to the height of the steel ball falling freely on the foam plastic sample at a specified height, and the rebound rate is used to express the resilience of the foam plastic. The instrument is controlled by microprocessor, liquid crystal display in Chinese and printing test data. It has the characteristics of safe use, reliability and high measurement accuracy.

Sponge rebound tester is an instrument used to measure the rebound performance of sponge, foam, rubber and other soft materials. It is mainly an instrument for measuring the rebound height of a steel ball freely falling on a soft foam plastic or other elastic material sample. This instrument is mainly used to determine the resilience (coefficient of resilience) of polyurethane elastic material test items.

Sponge rebound instrument has the characteristics of high automation, simple operation, high precision and safety protection. It is controlled by microprocessor, can automatically complete the test process, and equipped with LCD screen to display test data and results in Chinese form. In addition, it also has a data storage function, which can save multiple sets of test data, which is convenient for users to view, analyze and compare at any time.

In the test process, sponge rebound instrument adopts photoelectric technology and electromagnetic control technology to ensure the accuracy and reliability of the test results. At the same time, in order to protect the test sample and the instrument itself, special safety protection devices are set up, such as limit protection and overload protection. In addition, it is equipped with a micro printer that can print out test results for easy archiving and recording by users.

In a word, sponge rebound tester is a kind of testing instrument with complete functions, high degree of automation, easy operation and high precision, which is suitable for testing the rebound performance of various soft materials such as sponge, foam and foam.

Use method of sponge foam falling ball resilience tester:

1. Installation preparation: Before using the sponge rebound tester, it is necessary to prepare the test sample and cut the sample into squares or circles. The size should be suitable for the specifications of the test device.

2. Instrument adjustment: When using the instrument for the first time, it is necessary to adjust the foot of the base so that the bubble in the right corner of the square level is adjusted to the center of the circle to ensure that the base is in a horizontal state.

3. Sample placement: Place the test sample in the center of the test setup.

4. Parameter setting: according to the test requirements, set the test times, test speed and other parameters.

5. Start Test: Press the Start button and the instrument will automatically perform the test. During the test, the rebound of the test sample can be observed through the observation window.

6. Data recording: After the test is completed, the instrument will automatically record the test data. Test data can be printed or saved.

7. Cleaning and maintenance: After the test is completed, it is necessary to clean the test device and sample, and keep the instrument clean and tidy.

It should be noted that the specific operating procedures may vary depending on the instrument model and manufacturer. When using sponge rebound tester, the operating procedures and instructions of the instrument should be followed to ensure the accuracy and reliability of the test results. At the same time, attention should also be paid to the maintenance of the instrument, regular cleaning and maintenance to ensure its normal operation and service life.
