Application of Porosity Tester in Thermal Paper

The air permeability Tester can also be used for the air permeability test of thermal paper to determine whether the airtightness and air permeability of thermal paper meet the requirements and ensure the quality and performance of thermal paper products.

In the production process of thermal paper, air permeability testing can help manufacturers determine better production processes and formulas, and improve product quality and performance. At the same time, the air permeability test can also be used in the application research of thermal paper, such as the application in various thermal printing equipment such as printers, POS machines, cash registers, etc., to provide scientific basis and technical support for the application of thermal paper.

Generally speaking, the air permeability test of thermal paper can adopt wet method or dry method. The following is a common test method:

1. Prepare the sample: Take a sample of an appropriate size from the thermal paper and cut it into a standard shape and size with a sample cutter or scissors.

2. Adjust the instrument: turn on the air permeability Tester, and set relevant parameters according to the test requirements, such as temperature, humidity, test time, etc.

3. Install the sample: place the sample on the test instrument and install it correctly according to the operating instructions of the instrument.

4. Carry out the test: start the test instrument and perform the test as required. During the test, it is necessary to observe the instructions of the test instrument and check whether the sample is deformed or damaged.

5. Record data: After the test is completed, record the test results according to the instructions of the test instrument, including air permeability value, temperature, humidity, test time and other related parameters.

6. Analysis results: Analyze and compare according to the test results to judge whether the air permeability of thermal paper meets the requirements, and further improve the production process and formula.

Different types of thermal paper will have different air permeability, so it is necessary to have a certain understanding of the characteristics of thermal paper before testing, and choose the appropriate test method and parameters according to the actual situation. At the same time, it is necessary to pay attention to operating specifications and safety measures when conducting tests to ensure the accuracy of test results and personnel safety. When performing an air permeability test, appropriate test parameters and test methods should be selected according to the actual situation of the thermal paper to ensure the accuracy and reliability of the test results.
