Dart impact testerIt is a professional test equipment used to test the impact resistance of plastic films and sheet materials. By simulating real-world application scenarios, the impact energy and mass of the film when it breaks under the impact of a free dart at a given height are measured, so as to evaluate the impact resistance of the film. This article will introduce in detail the working principle, structural characteristics and application fields of dart film impact tester to provide you with useful references.
1. The working principle of the dart type film impact tester
The dart impact tester is designed and manufactured in accordance with the national standards GB T 9639 "Test Method for Impact Resistance of Plastic Film and Sheet: Free Dart Method" and ISO 7765 "Determination of Impact Resistance of Plastic Film and Sheet - Free Dart Method". During the test, the mass of the dart, the height of the dart and the number of impacts were adjusted to simulate the force of the film under different conditions. In the impact process, an electromagnet automatic capture system is used to prevent the specimen from being impacted twice. Based on the results of the impact test, the impact resistance of the film can be analyzed.
2. Structural characteristics of dart type thin film impact tester
1.Imported pneumatic components to ensure the stability and accuracy of the test.
2.Electrically lifting weights for precise control of the quality of the darts.
3.The size of the dart hemispherical head can be adjusted to meet different test needs.
4.The outer diameter of the weight and the diameter of the center hole are reasonably designed to ensure the accuracy of the test data.
5.The specimen thickness and geometry are adjustable, making it suitable for a wide range of film materials.
6.The electromagnet automatic capture system prevents the specimen from being hit twice.
7.Microcomputer processing of test data to improve test efficiency.
8.The unique illuminated observation lamp makes it easy to observe the test process.
9.The safety protection measures are complete to ensure the safety of the test process.
10.The intelligent operating system realizes the automation and intelligence of the test process.
3. Application field of dart type thin film impact tester
Dart film impact tester is widely used in plastic film, packaging materials, composite materials and other industries. By testing the impact resistance of the film, it helps enterprises to grasp the quality of products, optimize the production process, and meet market demand. In addition, the equipment can also be used in scientific research units, quality inspection departments and schools to provide strong support for the research and testing of thin film materials.
In short, the dart film impact tester is a kind of testing equipment with important practical value, and it is of great significance for plastic film and composite materials and other industries to master its performance indicators and application methods. It is hoped that this paper can provide a useful reference for relevant enterprises and researchers and help the development of China's thin film materials industry.
