What is a 180 degree peel strength testing machine?
In the fields of industrial production, material science and product quality testing, the 180-degree peel strength testing machine is an important testing equipment. It is mainly used to measure the bonding strength between materials, and is especially widely used in peeling performance testing of tapes, labels, films, coatings and other materials. This article will introduce in detail the definition, working principle, application fields and technical parameters of the 180-degree peel strength testing machine to help readers fully understand this equipment.
1. Definition of 180 degree peel strength testing machine
The 180-degree peel strength testing machine is a device specially used to test the bonding strength of materials at a 180-degree peel angle. It simulates the peeling force in actual use and measures the force required by the material during the peeling process to evaluate the bonding performance of the material. This kind of testing machine usually consists of a tensile sensor, a clamp, a control system and a data acquisition system, which can accurately record the force value changes during the peeling process.
2. Working principle of 180 degree peel strength testing machine
The working principle of the 180-degree peel strength testing machine is relatively simple. During testing, one end of the material to be tested is fixed on the fixed fixture of the testing machine, and the other end is fixed on the movable fixture. The moving clamp peels off the material at a constant speed (usually 300mm/min), while the tension sensor measures the force required during the peeling process in real time. The data acquisition system records the force value and generates a force-displacement curve, and finally calculates the peel strength of the material.
3. Application fields of 180 degree peel strength testing machine
180 degree peel strength testing machine is widely used in the following fields:
| Application areas | Specific use |
|---|---|
| Tape industry | Test the bonding strength between tape and substrate |
| label industry | Evaluate the bonding performance of labels to packaging materials |
