Brief introduction: The instrument use spinning drop method to measure the surface tension of the liquid, liquid / liquid interfacial tension and liquid / solid contact angle of special instruments. The main application areas are: 1.tertiary recovery (chemical flooding oil) indoor research and field monitoring; 2. study of surfactants, detergents, emulsions and foams research; 3.fuel oil, lubricants, paints, inks and coatings; 4.paper products, photographic materials, pesticides, etc., ..The main features 1 PC computer and the whole process is controlled by a pre-SBC, the use of computer technology to collect rotating droplets multimedia video images were analyzed 2 master program is Winndows interface, easy to operate, as a standard BMP image files can be stored print. 3 Tension wide measurement range, from 10-5mN / m to 100mN / m, across seven orders of magnitude, measuring instrument for the whole range of tension. 4 high accuracy the number of stalls providing magnification, the width of a human hair can be enlarged to hundred pixel, greatly improve the measurement accuracy of ultra-low interfacial tension. 5 in one machine, which can measure the interfacial tension and contact angle, which conducted the study wettability. For the general case of contact measurement, the instrument allows the rotating body in a regular droplets, thereby to ensure measurement accuracy and precision. Also, measure the contact angle when the liquid / liquid interfacial tension of ultra-low-value, which is very convenient, it is the other contact angle measuring instrument is difficult to do. 6 with electric heating temperature control system, capable of constant temperature experiments. Technical indicators: 1 Tension Measuring range: surface and interfacial tension 1x10-5 -100mN / m 2 Reading range: 0-4mm (available in 2mm and 4mm high purity quartz sample tube) 3 reading measurement accuracy 0.001mm 4 speed control range 1000-10000r / min Accuracy: 0.1% 5 temperature display range: 0-100 °C (built-in heating RT + 5 °C to 80 °C or external bath temperature) 6 Temperature display accuracy: ± 0.1 °C 7 computers and stand-alone real-time operating temperature and speed settings 8 video detection system resolution: 768x576 9 Video capture rate: 25 frames / sec. 10.RS-232 serial port (test data); VIDEO RCA connector (video capture) 11.220V / 50 Hz or 110V / 60Hz
