Description

Technical Field

[0001] The utility model mainly relates to the field of plasticizer preparation, and in particular to a sample collecting device. Background Art

[0002] Plasticizers, also known as plasticizers, are widely used additives for polymer materials in industrial production. Any substance added to a polymer to increase its plasticity is called a plasticizer. Plasticizers can improve the performance of polymers, reduce production costs, and increase productivity. They are an important class of chemical additives, commonly used as additives in materials such as plastics and concrete.

[0003] During the operation of the specific embodiment, the inventors found the following defects:

[0004] However, during the preparation process of the plasticizer, it is necessary to sample the plasticizer through a sample collecting device for testing the plasticizer. However, since the interior of the plasticizer is in a closed state during the preparation process, the sample collecting device cannot sample and test the plasticizer being prepared.

[0005] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content
