What is a plastic impact testing machine?
In the field of industrial production and quality inspection, the plastic impact testing machine is an important testing equipment used to evaluate the toughness and impact resistance of plastic materials when impacted. This article will introduce in detail the definition, working principle, application scenarios of plastic impact testing machines, as well as hot topics and hot content in the past 10 days.
1. Definition of plastic impact testing machine
Plastic impact testing machine is a device specially used to test the performance of plastic materials under impact load. It evaluates a material's impact resistance, fracture toughness and durability by simulating the impact forces the material may encounter in actual use. Common test methods include Izod impact testing and simply supported beam impact testing.
2. Working principle of plastic impact testing machine
The working principle of the plastic impact testing machine is based on the law of conservation of energy. During the test, the pendulum is released from a certain height, impacts the sample, and the energy absorbed when the sample breaks is measured. By calculating the impact strength, the toughness of the material can be judged. The following are the key parameters of the plastic impact testing machine:
| parameters | Description |
|---|---|
| impact energy | The initial energy of the pendulum when it is released, usually measured in joules (J) |
| Impact speed | The speed at which the pendulum impacts the specimen affects the test results. |
| Sample size | Standard sample size is usually 80mm×10mm×4mm |
| Test temperature | Some tests need to be performed at specific temperatures to simulate actual environments |
3. Application scenarios of plastic impact testing machines
Plastic impact testing machines are widely used in the following fields:
4. Hot topics and content in the past 10 days
