[0030] Working principle: First, the titanium oxide-chitosan sol sample to be tested is placed in the detection tank 19, and the detection tank 19 is placed on the fixed detection platform 18 through friction contact to ensure its stability. The telescopic action of the electric telescopic rod 22 drives the linkage block 21 and the fixed slider 20 to slide along the second slide rail 17, and then adjusts the position of the detection tank 19 so that it is accurately located directly below the capillary 13, ready for surface tension measurement. The electric lifting rod 8 is started, pushing the slide block 7 down along the slide rail 6, driving the connecting block 9 and the detection head 10 to move to a suitable height to ensure that the capillary 13 can be accurately inserted into the sol sample. The air pump 11 is started to inflate the inert gas cylinder 12. The slow release of the inert gas cylinder 12 forms a stable airflow in the capillary 13. When the airflow contacts the surface of the sol, a pressure change related to the surface tension will be generated. When the capillary 13 is inserted into the sol, the surface tension of the sol will hinder the airflow, causing the pressure in the capillary 13 to change. This pressure change is monitored in real time by the pressure sensor 14 and converted into an electrical signal. The monitoring and recording device 15 receives the electrical signal from the pressure sensor 14, and after processing and analysis, displays and records the surface tension value of the sol. The entire measurement process can be automatically controlled by the control panel 23, including the start and stop of the electric lifting rod 8 and the electric telescopic rod 22, the flow adjustment of the air pump 11, etc. The monitoring and recording device 15 not only displays the measurement results in real time, but also stores the data for subsequent analysis. After the measurement is completed, the electric lifting rod 8 descends, driving the detection head 10 and the capillary air tube 13 away from the sol sample to avoid contamination or damage to the sample. The electric telescopic rod 22 drives the detection tank 19 back to the initial position to prepare for the next measurement.
