JK99M1 Fully Automatic Tensioner

The force generated at the interface between a liquid and another immiscible liquid is called the interfacial tension between the liquid phase and the liquid phase; Meanwhile, we usually refer to the tension between liquid and gas phases as surface tension. For example, at 20 ℃, the surface tension of water is 72.75mN/m, which refers to the surface tension at the interface between water and air.
There are many methods for measuring surface/interface tension, and the JK99M series fully automatic tensiometer uses the most commonly used platinum plate method and platinum ring method in production practice. Its application areas include indoor research and on-site monitoring of tertiary oil recovery (chemical flooding); Research on surfactant, detergent, emulsion and foam; Research on fuel oil, lubricants, paints, inks, and coatings; Research on pesticides and other related fields.
The JK99M1 fully automatic tension meter can also be equipped with functions such as magnetic stirring, CMC concentration measurement, density measurement, powder measurement, fiber contact angle measurement, dynamic contact angle measurement, etc. according to different customer requirements. It can also be configured as an all-in-one machine: built-in touch LCD digital display, including a roll type printer, which can be operated independently or connected to a computer to control and observe the dynamic changes of tension curve.

1、 Platinum Plate Method and Platinum Ring Method:

Platinum plate method: The sampling period is 1-5 seconds, which is most convenient for viscous liquids. When the sensing platinum plate is immersed in the measured liquid, the surface tension around the platinum plate will be affected, and the surface tension of the liquid will pull the platinum plate down as much as possible. When the surface tension and other related forces of the liquid reach equilibrium with the equilibrium force, the sensing platinum plate will stop immersing into the interior of the liquid. At this point, the balance sensor of the instrument will measure the immersion depth and convert it into the surface tension value of the liquid.

Platinum Ring Method: Sampling period of 50-200 seconds, fully automatic process can be divided into: (1) Gently immerse the platinum ring into the liquid; (2) Slowly lift the platinum ring upwards, causing the liquid level to relatively decrease, forming a liquid column below the platinum ring and ultimately separating from it. The platinum ring method is used to sense a maximum value, which is formed when the platinum ring is about to separate from the liquid sample but not yet. The accuracy of converting this highest value into surface tension value depends on the viscosity of the liquid.
