The JY-PHd contact angle measuring instrument is used to measure the contact angle between solid, liquid, and gas phases, and based on this, it calculates surface physicochemical properties such as liquid adhesion to solids, solid surface tension, and solid surface energy. This instrument is widely used in the fields of petroleum, chemical engineering, papermaking, dyes, and various new material research and manufacturing. It employs computer technology to achieve image storage, analysis, and printing, featuring fast speed, accurate data, convenient operation, high automation, and precise measurement.
1. Automatic Contact Angle Analysis: Utilizing ellipse fitting for automatic analysis, the system employs machine vision to automatically identify baselines and droplet contours. Based on the Laplace equation, it performs quadratic curve fitting calculations to minimize gravitational effects and eliminate human errors. Additionally, it supports automatic analysis using polynomial partial contour fitting methods. 2. Automatic Surface Tension Analysis: Following the pendant drop test standard method, the system automatically identifies droplet contours and calculates surface tension. 3. Automatic Sampling: Equipped with an automatic micro-sampler, the system allows for easy liquid replacement with high sampling precision. It is particularly suitable for scenarios requiring frequent testing of different liquids. 4. Dynamic Testing Function: The system supports the measurement of dynamic contact angles (advancing and receding angles) using the droplet addition/subtraction method. For the JY-PHd model, it also incorporates the tilting plate method, where an electric rotating stage creates an inclination to measure advancing and receding angles during droplet rolling.
The instrument measures contact angles through the static drop method, the advancing/receding drop method, and the tilting plate method (JY-PHd type). The static drop method involves dripping liquid onto a solid surface, photographing it after the three-phase interface stabilizes, and measuring the contact angle via software. The equilibrium process can also be photographed or recorded at regular intervals to analyze changes. The advancing/receding drop method measures dynamic contact angles, such as advancing or receding angles, by continuously increasing or decreasing the droplet volume. The tilting plate method utilizes an electric rotating stage to create an inclination, causing the droplet to tilt and roll under gravity, thereby determining its advancing and receding angles.

SY-T 5370 Method for Determination of Surface and Interfacial Tension
1. Static Drop Method: A liquid droplet is deposited on a solid surface, and after the solid-liquid-gas three-phase interface reaches equilibrium, a photograph is taken to measure the contact angle using software. Alternatively, the equilibrium process can be analyzed by taking timed photographs or recording a video. 2. Droplet Increase/Decrease Method: The advancing contact angle is measured by continuously increasing the droplet volume, while the receding contact angle is measured by continuously decreasing the droplet volume. 3. Tilting Plate Method (JY-PHd Type): An electric rotating stage is used to create an inclined surface, allowing observation of the droplet tilting and eventually rolling under the influence of gravity. The advancing and receding contact angles are measured during this process.
