Description

Technical Field

[0001] The utility model relates to a glass square trough for medium resistance test of laboratory test pieces, belonging to the technical field of physical and chemical laboratory appliances. Background Art

[0002] The non-metallic materials (paint, oil, adhesive) in the physical and chemical laboratory are subjected to the medium resistance performance test. The types of media include kerosene, gasoline, lubricating oil, organic solvents, etc. After the test pieces are painted or coated with glue, they are placed in the glass square tank for medium resistance (oil) test. After a certain temperature and time, the changes in the test piece coating are observed. In the past, the material medium resistance test was to directly place 3-6 test pieces in a simple glass tank. The test pieces were not easy to separate. Sometimes, the position of the test pieces in the tank changed due to the movement of the glass tank containing the test pieces during the process of placing them in the oven, which easily caused the test pieces to fit together. The test pieces could not fully contact the medium, affecting the medium (oil) resistance effect. If the test pieces are separated by spacers in the glass tank, the contact between the spacers and the medium affects the quality of the medium (oil). At the same time, the movement of the spacers during the moving of the container can cause the test pieces to slip easily, making it difficult to ensure the accuracy of the medium (oil) resistance performance.
