Overview of JJ2000D1 Rotating Drop Interface Tensioner
From the JJ2000A model in 1999 to the subsequent JJ2000B, JJ2000B2, JJ2000C, and JJ2000H series, Shanghai Zhongchen Digital Technology Equipment Co., Ltd. has launched a rotating droplet interfacial tension meter with completely independent intellectual property rights including invention patents, which has been available for a full 20 years!JJ2000D1 type rotating droplet interfacial tension meter is developed by Shanghai Zhongchen Digital Technology Equipment Co., Ltd. It integrates some American technologies on the basis of its own products. Based on the new research results of domestic surface and colloid chemistry experts, it adopts computer control and multimedia technology, and is based on JJ2000C type rotating droplet interfacial tension meterThe latest product developed by improving the classic plug-in sampling tube method, stainless steel anti-corrosion heating system, and image acquisition technologyThis product is easier to operate and has a more stable system. The main application areas include: indoor research and on-site monitoring of tertiary oil recovery (chemical flooding) in oil fields; Research on surfactant, detergent, emulsion and foam; Research on fuel oil, lubricants, paints, inks, and coatings; Research on pharmaceuticals, paper products, photosensitive materials, pesticides, and other related fields.

Characteristics of JJ2000D1 Rotating Drop Interface Tensioner
1. The instrument has improved the pull-out method of quartz glass tubes,The spring pin is pressed against the sample tube and automatically pops out when taken out, making the sample tube less likely to breakLoading the sample before testing during injection makes it easier to clean and easier to operate. Due to the use of stainless steel inner sleeve and stainless steel rotor, the coefficient of expansion is similar, which is conducive to temperature conduction, and the material is not easily corroded or rusted. With high concentricity, the sample tube is easier to maintain horizontal stability and less prone to shaking.
2. The entire process is controlled by a PC computer and a front-end single board computer, using computer multimedia video technology to collect images of rotating droplets for analysis and calculation, which has excellent operability and repeatability.
3. Adopting the latest precise LED control technology, while updating high-speed CCD and trigger mode image acquisition, the screen does not flicker under low-speed and high-speed rotation conditions, and the interface edge imaging effect is clearerIt is beneficial for analyzing the fine characteristics of turbid samples in oil fields.
4. The main control program is a Windows interface, easy to operate, and the image is a standard BMP file that can be stored and printed. The program adopts advanced interface tension measurement calculation technology. Just press "test", and our software automatically controls the shooting speed, saves the image, calculates the interface tension value, and displays the measurement value. The process does not require manual intervention, effectively avoiding the influence of human factors on the measurement value. It can record the interface tension values that change with time, speed, and temperature, and store all measured values in the database. At the same time, it can be directly exported as an EXCEL document, and the measured value curve graph can also be displayed in real time. Humanized software design, powerful database management method to manage all test data.
5. The interface tension measurement range is wide, from 10-6mN/m to 100mN/m, spanning eight orders of magnitude, making it a full-scale tension measuring instrument.
6. Adopting the high-speed motor imported from PITTMAN in the United States, it has a complete servo motor control system with better upgrades and compatibility. The control speed can reach up to 10000 revolutions per minute (or choose a motor with a higher speed of 14000 revolutions per minute), and the accuracy can control the speed to ± 5 revolutions per minute. The motor encoder control point can reach up to 500 points per circle, with higher accuracy and more convenient operation. The addition of precision arc pendulum platform and one-dimensional focusing platform enables high measurement accuracy of the instrument, while providing multiple levels of magnification, which can enlarge the width of hair strands to over 100 pixels, greatly improving the measurement accuracy of ultra-low interfacial tension.
7. Equipped with an electrically controlled temperature heating system, capable of maintaining a constant experimental temperature. instrumentAdopting precise PID temperature control technology, the heating component adopts a new anti-corrosion stainless steel design scheme, which has fast thermal conductivity and is easier to uniformly heat the sample tubeThere is no need to connect other temperature control devices. The instrument can also choose a super constant temperature bath for temperature control, and the two temperature control systems are compatible.
8. Low noise electric imaging mechanism, interface button operation, simple and convenient. The three-point horizontal adjustment design scheme can facilitate the control of droplets within the visible window range. Optional JJ2000B model's classic rotary swing mechanism is available, which is beneficial for balancing the position of droplets. High end automatic imaging can be optionally selected, eliminating the need for manual adjustment of droplet position during testing, making operation more convenient.
9. Integrate new technology, industrial touch screen and Internet of Things technology, and keep up with the innovative products of Internet plus.
