drilling fluidZetaPotentiometerCan be used to determine the solid-liquid interface electrical properties of dispersed system particles（ζThe potential can also be used to measure the interfacial electrical properties of emulsion droplets, as well as to determine the isoelectric point and study the mechanism of interfacial reaction processes. By measuring the particle sizeZetaPotential, finding the isoelectric point, is an important method for understanding the surface electrical properties of particles, and is also an important means in particle surface treatment. Compared with other similar instruments at home and abroad, it has significant * performance. It can be widely used in industries such as cosmetics, mineral processing, papermaking, medical and health care, building materials, ultrafine materials, environmental protection, marine chemistry, etc. It is also one of the important teaching instruments for majors such as chemistry, chemical engineering, medicine, and building materials.

Characteristics of Measurement Technology
1. The instrument adopts a newly designed and simple electrophoresis cell, which uses0.5cm A thick glass cup with electrodes built into the pool. The electrophoresis cup and built-in electrodes undergo precise microfluidics calculations and surface treatment to form a set of electrophoresis devices that are different from traditional electrophoresis cells. The sample usage during testing is extremely small, with only a small amount used each time0.5mlEasy to clean, convenient to use, economical and practical.
2. The electrode holder is carefully designed and closely matched with the electrophoresis cup to form a cup-shaped open electrophoresis device. The electrodes are made of silver, platinum, and titanium metal wires, and after surface treatment, the working state is stable.
3. Well made cross markers are placed in electrophoresis cups and placed on a 3D platform. After adjusting the 3D platform, a clear cross image can be seen on the computer screen to locate the measurement position without any static layer issues.
4. The electrophoresis instrument adopts a semiconductor luminescent near-field optical system with a power of only a few tens of microwatts, which will not affect the measurement environment and accuracy due to heat generation. The optical system has been adjusted, and the magnification has been increased. Short wavelength blue and green light are used, so smaller particles can be seen clearly.
5. Adopting constant voltage low-frequency conversion power supply,It can prevent polarization while greatly improving measurement speed. The positive and negative reversal time is0.30Seconds to1.20Seconds continuously adjustable, sampling time only requires 3～10In seconds. The voltage between electrodes can be adjusted as needed.
6. Using temperature sampling probe,Automatically and continuously sample the ambient temperature,Return to the computer, automatically adjust parameters for calculationZetaElectric potential. Adopting computer multimedia technology,At the given beat,Automatically magnify at high magnification1200Continuous ultra-fine particles“take a photo”Provide four grayscale images in both directions for analysis and calculation.
