    Introduction of JN01A thick paste electrophoresis instrument
          Determination of the isoelectric point by measuring the zeta potential of the particles is an important method for understanding the electrical properties of the surface of the particles, and is also an important means in the surface treatment of particles. JS94 series micro-electrophoresis (Zeta potentiometer) produced by Shanghai Zhongchen Digital Technology Equipment Co., Ltd. is an instrument for measuring the electrical properties of particles. Because JS94 series micro-electrophoresis (zeta potentiometer) is suitable for dilute dispersion system, for concentrated dispersion system, It needs to be measured after dilution. If you want to measure the original state of the concentrated dispersion system, the JN01A thick paste electrophoresis system may be more suitable.
          The JN01A thick slurry electrophoresis apparatus uses the mass exchange method to determine the zeta potential. The so-called mass exchange type Zeta potential meter actually determines the zeta potential according to the electrophoresis speed, but instead of observing the moving speed of the particles one by one, the speed is converted into mass, and the directional moving particles are collected on the electrodes, according to the increase of the electrodes. Recalculate the zeta potential. The electrode that collects the particles is the bottom of the sample cell that can be freely loaded and unloaded, and its weight gain is obtained by weighing the sample cell before and after the experiment. Since the electrode also discharges the same volume of liquid medium while collecting the oppositely charged particles, the weight gain obtained is actually the weight of the particles deposited on the electrode minus the weight of the same volume of liquid.
          The same kind of instruments in the United States are weighing methods, but it is difficult to accurately weigh. The weight gain of the JN01A thick paste electrophoresis instrument is based on the difference in light transmittance of different concentrations of liquid, first obtain the light transmittance, and then obtain the corresponding The liquid concentration is determined by the change in concentration. Therefore, compared with other instruments of the same type at home and abroad, the JN01A thick slurry electrophoresis instrument has remarkable advantages.
          Of course, it is convenient to measure the zeta potential of charged particles in the dispersion system, or the JS94 series microelectrophoresis (zeta potentiometer), and the amount of sample consumed is also small. When using the JN01A thick paste electrophoresis system, the user needs to bring the conductivity meter, hydrometer/pyrometer, viscometer to measure the relevant data, and input it in the experimental operation software interface, so that the software can automatically calculate the result.
    Main features of JN01A thick paste electrophoresis instrument
    1. Converting the sample cell weight gain to the Zeta potential, there is no representative problem.
    2. During the measurement process, the sample cell is in a state of constant rotation, avoiding the problem of excessive particle precipitation.
    3. The weight gain of the sample cell contains the total results of large particles and small particles, and there is no problem that is not observed by small particles.
    4, measured with a higher concentration of sample liquid, close to the original state of the actual use of petroleum and paper industry.
    The JN01A thick slurry electrophoresis apparatus is mainly suitable for determining the zeta potential of particles in high concentration and concentrated dispersion systems, for example:
    1. For the petrochemical industry: determine the zeta potential of mud in oil drilling.
    2, can be used for sewage treatment: between the sewage and the medium in the industrial sewage often has a certain zeta potential to become a suspended state, by reducing the zeta potential of the system, the dirt charge is reduced, no repulsive force occurs and the coagulation subsidence Therefore, using the instrument to determine the zeta potential of the system, the process conditions can be controlled, and an appropriate amount of flocculant is added at an appropriate point to reduce the zeta potential of the system, thereby achieving the purpose of purifying water.
    3. Used in the paper industry. In the papermaking and coating preparation, it is necessary to control the production process by measuring the zeta potential of the system to obtain high quality paper.
    4. In addition, the instrument can also be widely used in cosmetics, mineral processing, medical and health, building materials, ultra-fine materials, environmental protection, marine chemistry and other industries. It is also one of the important teaching instruments for chemical, chemical and building materials.
  • The microelectrophoresis apparatus can be used to determine the solid-liquid interface electrical properties (ζ potential) of the dispersed system particles, and can also be used to measure the interface electrical properties of the emulsion droplets, and can also be used to determine the isoelectric point and study the mechanism of the interface reaction process. The determination of the isoelectric point from the pH-Zeta potential relationship diagram by measuring the zeta potential of the powder is an important method for understanding the surface electrical properties of the powder, and is also an important means in the surface treatment of the powder. Compared with other instruments of the same type at home and abroad, it has remarkable advantages. It can be widely used in cosmetics, mineral processing, paper making, medical and health, building materials, ultra-fine materials, environmental protection, marine chemistry and other industries. It is also one of the important teaching instruments for chemical, chemical, medical and building materials.
