Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone shell detection equipment, in particular to a heat stabilizer testing device for PVC. Background Art

[0002] Polyvinyl chloride (PVC) is a polymer material widely used in construction, pipelines, wire and cable, packaging, and other fields. However, due to its susceptibility to heat and light during processing and use, the stability of PVC materials is often challenged. To enhance the stability of PVC materials, heat stabilizers are often added to their formulations. The main function of heat stabilizers is to prevent PVC from decomposing at high temperatures, thereby extending the material's service life and improving its heat resistance.

[0003] Currently, there are many types of heat stabilizers available on the market, such as organotin stabilizers, metal soaps, and composite stabilizers. Each heat stabilizer has its own specific mechanism of action and scope of application. However, the stabilizing effect of different heat stabilizers, as well as their dispersibility and compatibility in PVC materials, can vary significantly.

[0004] However, current PVC heat stabilizer testing equipment often places PVC blocks with heat stabilizers in a baking tray to heat them, then takes them out to observe changes in the PVC blocks, thereby judging the performance of the heat stabilizer in the PVC blocks. Using this testing method, the PVC blocks are mostly fixed, resulting in uneven heating of the PVC blocks, which can easily lead to errors in the heating temperature of each PVC block, resulting in inaccurate test results and prone to errors in the test.
