Description

Technical Field

[0001] This invention relates to the field of mesophase pitch viscosity testing technology, specifically to a temperature control device and method for testing the viscosity of mesophase pitch. Background Technology

[0002] Mesophase pitch is a type of ordered colloidal phase with optical anisotropy, which is formed during the heat treatment process of transitioning organic matter to carbon materials. It is produced by the pyrolysis and condensation reaction of isotropic parent pitch and is rich in large planar polycyclic aromatic hydrocarbon molecular clusters. These molecular clusters can spontaneously align themselves in the molten state due to the liquid crystal properties, forming an ordered colloidal phase between liquid and solid states. As a core precursor for the preparation of advanced carbon materials such as high-performance carbon fibers and mesophase carbon microspheres, its molecular structure, texture, and rheological properties directly determine the microstructure and macroscopic properties of the final carbon materials. When testing the viscosity of mesophase pitch, it is necessary to first place the mesophase pitch in a temperature control device for constant temperature treatment.

[0003] However, existing temperature control devices lack auxiliary mechanisms on the lid during use, allowing staff to easily remove and take it away. This can disrupt the stability of the constant temperature environment inside the tank, leading to heat loss, increased temperature fluctuations, and rapid evaporation of the solution. This not only directly affects the accuracy and repeatability of experimental data but may also accelerate scaling of the equipment due to frequent water replenishment, shortening its service life.
