Laboratory heat seal instrument is a kind of instrument used to test the heat seal strength and heat seal performance of plastic film, composite film and other materials. Its principle is based on the physical process and thermal principle of heat sealing.

작동 원리
The laboratory heat seal instrument usually consists of two heat heads, which can heat and press two films together to form a heat seal area. 시험 중, it is necessary to place the film sample to be tested in the heat seal area, adjust the temperature and pressure and other parameters, and carry out the heat seal test.

The process of heat sealing mainly includes heat conduction, melting and curing steps. When the heat head is heated to a certain temperature, the temperature on its surface is higher than the melting point of the film, and the film begins to melt. At the same time of melting, heat energy will transfer from the heat head to the film, so that the surrounding material will also begin to melt. When two melted films meet, they will form a certain heat seal area through heat energy transfer. After the heat seal is completed, the film will begin to cure and form a certain heat seal strength, which is used to test the heat seal performance.

In the laboratory heat sealing instrument, the heat sealing process can be controlled by adjusting the heating temperature, 압력, time and other parameters, and the heat sealing strength and performance of the film can be tested. Through the heat seal test, the heat seal quality, reliability and durability of materials can be evaluated, providing technical support and reference for the application of materials.

운영 절차
The following are the basic operation steps of the laboratory heat sealing instrument:

샘플 준비: According to the test needs, prepare the film samples that meet the requirements, usually need to be cut, 자르다, cleaning and other processing, to ensure that the samples meet the standard requirements.

테스트 매개변수 조정: place the heat head on the test platform and adjust the test parameters such as temperature, pressure and time to meet the test requirements and standard requirements. When adjusting the parameters, it is necessary to refer to the test standard and instrument manual, and adjust according to the actual situation.

Place the sample: Place the prepared sample between the hot heads, position and place according to the standard requirements and test needs. When placing samples, it is necessary to pay attention to factors such as the number, location and density of samples to ensure the accuracy and reliability of test results.

Perform the test: Press the test button and the instrument starts to perform the test automatically. 테스트 과정에서, it is necessary to monitor the test data and instrument status, record and deal with the test results and abnormal conditions in time. As required, multiple tests can be performed to obtain more accurate test results.

결과 분석: 시험이 끝나면, the results were analyzed and evaluated according to the test results and standard requirements to determine the heat sealing strength, heat sealing performance and appearance quality of the samples. When analyzing the results, it is necessary to refer to the test standards and technical requirements, and make the necessary comparisons and statistics.
