Description

Technical Field

[0001] The utility model belongs to the technical field of detection instruments, and particularly relates to a stirring structure and a softening tester. Background Art

[0002] Asphalt is a complex, dark-brown mixture of hydrocarbons and non-metallic derivatives of varying molecular weights. It is a high-viscosity organic liquid with a black surface and is soluble in carbon disulfide. Key asphalt performance indicators include ductility, penetration, and softening point. The asphalt softening point test is suitable for determining the softening point of road petroleum asphalt and coal tar, as well as the residual softening point of liquid petroleum asphalt after distillation or evaporation of softened asphalt. Existing asphalt softening point testing devices often have several drawbacks. When stirring water in a beaker, the beaker is unstable and prone to horizontal displacement, resulting in inaccurate testing. Currently available magnetic stirring methods often have the following drawbacks: When stirring glycerin at low temperatures, it cannot achieve good flow, resulting in uneven temperature control, making it difficult to achieve a 5±0.5°C temperature rise. Furthermore, single-blade mechanical stirring can easily cause asphalt deflection due to fluid movement. Therefore, developing a stirring mechanism and softening tester that overcomes these drawbacks is crucial. Utility Model Content
