I. Introduction. Tape electronic tensile testing machine is a widely used equipment for material testing, which is used to measure the tensile strength, tear strength, deformation rate and other performance indicators of tape, film and other materials. This article will introduce the test principle and performance indicators of the tape electronic tensile testing machine in detail.
Second, the test principle.
The tape electronic tensile testing machine adopts advanced testing principles, by clamping the specimen between the two chucks of the film tensile strength tester fixture, and the two chucks move relative to each other to simulate the tensile process of the sample. During the tensile process, a force sensor located on the moving chuck and a displacement sensor built into the machine collect changes in force and displacement during the test in real time.
Through these data, we can calculate the tensile strength, tear strength, deformation rate and other performance indicators of the specimen. Specifically, tensile strength refers to the maximum tensile force that a specimen can withstand during the tensile process;Tear strength refers to the force required by the specimen during the tearing process;The deformation rate refers to the degree to which the specimen is deformed during the stretching process.
3. Performance indicators.
Tensile strength: Tensile strength is one of the most important performance indicators of the tape electronic tensile testing machine. It reflects the tensile ability of the specimen during the tensile process and is an important basis for evaluating the properties of the material.
Tear Strength: Tear strength is the ability of a material to resist tearing when subjected to tearing action. By measuring the tear strength, we can understand how the material cracks when subjected to an external force.
Deformation rate: The deformation rate reflects how much a material is deformed during the stretching process. By measuring the deformation rate, we can understand how the material deforms when subjected to external forces, and thus evaluate the flexibility and plasticity of the material.
IV. Conclusions. Tape electronic tensile testing machine is an efficient and accurate material testing equipment, which is widely used in the performance testing of plastics, rubber, fibers and other materials. By measuring performance indicators such as tensile strength, tear strength and deformation rate, we can fully understand the performance characteristics of materials and provide strong data support for product design and production.
