It is a device specially used to test the tensile properties of plastic films and can accurately measure various mechanical indicators of the film under stress.
This article will introduce in detail the definition, working principle, application fields of plastic film tensile testing machine, as well as hot topics and content on the market in the past 10 days, to help readers fully understand this equipment.
1. Definition of plastic film tensile testing machine
Plastic film tensile testing machine is an instrument used to test the tensile strength, elongation at break, elastic modulus and other mechanical properties of plastic films. It simulates the stress of the film in actual use and conducts tensile, compression or bending tests on it to evaluate whether its performance meets the standard requirements.
2. Working principle of plastic film tensile testing machine
The working principle of the plastic film tensile testing machine mainly includes the following steps:
1.Hold sample: Fix the plastic film sample in the upper and lower clamps of the testing machine to ensure firm clamping to avoid slipping or falling off during the test.
2.Apply tension: A gradually increasing pulling force is applied to the sample through a motor or hydraulic system until the sample breaks.
3.Data collection: The built-in sensor of the testing machine collects tension, displacement and other data in real time, and analyzes and records them through the software.
4.Result output: Based on the test data, generate mechanical property reports such as tensile strength, elongation at break, etc.
