Shouzheng Knowledge Class: Falling Dart Impact Test

Hello everyone, today I will introduce to you a falling dart shock test, for the film products, especially most of the products used for packaging, such as High Barrier Packing Film of our company. In the actual use or transportation process, it is likely to receive the impact of external forces, such as in the case of falling.

In this case, if our company's product High Barrier Packing Film is used, then the loss of goods caused by the drop will be greatly reduced. Next, we will explain to you why you choose our product High Barrier Packing Film by introducing the falling dart shock test.

Today to introduce the falling dart impact test, is to simulate the film in the case of external force impact, can detect the impact of the film, and maintain its own integrity is not damaged.

This test can be performed in our company's laboratory.

Before the actual demonstration of the experiment operation, we should pay attention to remind everyone that this experiment involves the fall of the weight, which has a certain risk, so when we enter the laboratory for the actual operation, we should pay attention to wear safety shoes, to avoid the foot damage.

In actual operation, we hang a certain weight with the hammer on the instrument.

And then click the button to release the weight and let the weight impact the hammer surface. It should be noted that at the moment the weight falls, we should pay attention to catch the weight, so as to avoid the impact of the second drop on the experimental results.

After the end of an experiment, the weight is selected according to the situation that the membrane surface is broken or not. After collecting 10 data points of broken and not broken, it can be calculated and averaged according to the addition of the weight and the weight of each hammer, so as to get the actual impact value.

Let's look at the gloss again below. This test of gloss is to put the light on the Light Diffusion Film at a certain Angle. Similarly, light is refracted and reflected, reflecting in different directions due to the different flatness of the surface of the Light Diffusion Film.

In the test, we will detect how much light is reflected at the same Angle of the Light Diffusion Film. The higher the value, the smoother the surface, the more light is reflected at the same Angle.
