Introduction: The JJ2000D rotating drop interfacial tensiometer is a product developed by improving the classic plug-in sampling tube method, stainless steel anti-corrosion heating system and image acquisition technology on the basis of the JJ2000C rotating drop interfacial tensiometer. This product is easier to operate and the system is more stable. The main application fields are: laboratory research and field monitoring of tertiary oil recovery (chemical flooding) in oil fields; research on surfactants, detergents, emulsions and foams; research on fuel oil, lubricants, paints, inks and coatings; medicine, paper Research on products, photosensitive materials, pesticides, etc. Features: 1. The instrument has improved the way that the quartz glass tube can be removed and inserted. The spring thimble is against the sample tube, and it automatically pops out when it is taken out, so that the sample tube is not easy to break. When injecting the sample, it is easier to clean and operate after loading the sample into the test. Due to the use of stainless steel inner sleeve and stainless steel rotor, the expansion coefficient is similar, which is conducive to temperature conduction, and the material is not easy to corrode and rust, and the high concentricity makes the sample tube more stable in the horizontal direction and not easy to shake. 2. The whole process is controlled by a PC computer and a front-end single-board computer. The image of the rotating droplet is collected by computer multimedia video technology for analysis and calculation, which has very good operability and repeatability. 3. The LED control technology is adopted, and the high-speed acquisition CCD and trigger mode are updated to acquire images at the same time. The screen does not flicker under low-speed and high-speed rotation conditions, and the imaging effect of the interface edge is clearer, which is conducive to analyzing the fine characteristics of oilfield turbid samples. 4. The main control program is a Winndows interface, which is easy to operate, and the images are standard BMP files, which can be stored and printed. Just press "Test", our software automatically controls the speed of taking pictures, saves the image, calculates the interfacial tension value, and displays the measured value. The process does not require manual intervention, thus effectively avoiding the influence of human factors on the measured value. It can record the interfacial tension value that changes with time, rotation speed and temperature, store all the measured values in the database, and export them directly to EXCEL files, and can also display the measured value curve graph in real time. Humanized software design, powerful database management method to manage all test data. 5. The interfacial tension measurement range is wide, from 10-6mN/m to 100mN/m, spanning eight orders of magnitude, which is a full-scale tension measuring instrument. 6. With an electronically controlled temperature heating system, it can keep the experimental temperature constant. The instrument adopts PID temperature control technology, and the heating component adopts a new anti-corrosion stainless steel design scheme, which conducts heat quickly and is easier to uniformly heat the sample tube. There is no need to connect other temperature control equipment. The instrument can also choose a super constant temperature bath for temperature control, two sets of temperature control system compatible. 7.. Low-noise electric image finder mechanism, interface button operation, simple and convenient. The three-point level adjustment design scheme can easily control the droplet within the range of the viewing window. The classic rotating and swinging mechanism in the JJ2000B model is optional, which is conducive to balancing the droplet position. It can also be equipped with automatic image finder, no need to manually adjust the droplet position during the test process, and the operation is easier. 8. The innovative products of the Internet+ that integrate the new technology industrial touch screen and the Internet of Things technology to keep up with the times.
