Description

Technical Field

[0001] The utility model relates to the technical field of adhesive film odor detection, in particular to an adhesive film odor detection device. Background Art

[0002] The main reason why resin film products emit odor is that they are affected by many factors, such as the purity of the basic monomer, the stability of the glue synthesis process and equipment, the degree of reaction during the coating and drying process, and the amount of solvent residue.

[0003] During the coating process, due to the resin structure characteristics of resin film products, some odor-type small molecules are wrapped by the resin network chain and need to be under the action of a certain temperature to overflow the resin film layer and be discovered.

[0004] Since the concentration of some odor-type small molecules emitted from the inside of the film does not meet the minimum limit of VOC instrument detection, the instrument cannot detect them quantitatively, and the only option is to conduct manual odor detection, which is a cumbersome and unsafe process. That is, the sample is sealed in a glass container, and then the glass container is placed in a forced air drying oven for heat treatment. After the treatment, the glass container is taken out and the lid is opened for odor detection.

[0005] However, in actual detection, the application scenarios of the film are different, and the requirements for the film odor detection height are also different. For example, some scenarios have more stringent requirements, requiring the film to have no odor at a close distance. In this case, the detection position is closer to the film, while some scenarios have relatively loose requirements for film odor detection, and in this case the detection position is relatively far away from the film.

[0006] Based on this, it is extremely important to provide a film detection device that is suitable for inspection requirements in different scenarios. Utility Model Content

[0007] The utility model aims to provide a film odor detection device, which can evaluate the odor emitted by a resin film at different detection heights, thereby being applicable to film odor inspection requirements in different scenarios and improving the use flexibility of the detection device.
