Measures related to measuring the contact angle in front of the analyzer were introduced, should pay attention to the following two questions about the implementation: Balancing time and system temperature stability, when the system is not balanced, the contact angle will change, when the contact angle of said Dynamic contact angle, dynamic contact angle of a liquid on a number of large research activity on the viscosity of the solid planar or spreading is important (because the viscosity is large, the time length of the balance). Together, the temperature change on larger systems, because of changes in surface tension, contact angle will change, therefore, if one has Kipping up balanced system, the contact angle change can be related to changes in temperature, briefly determine the impact factors approach is the water contact angle measurement instrument, affect the balance of the time is usually in one direction, and the temperature fluctuations can be formed to increase or decrease γ. In addition to the time and temperature of the outer equilibrium contact angle measuring instrument infusion, the impact factor as well as the contact angle stable contact angle hysteresis and adsorption. When the contact angle measurements, the droplet size and the contact angle is no linear relationship between the amount of sample 0.6 ~ 1.0ul are the best, the droplets are too small by Volatile is too large, the droplet is too large gravity factor significantly. Note that the test should not be free-falling droplets dripping on the solid surface and the sample platform should rise, touch suspended in the lower end of the injector after the droplets fall, the droplets remain on the solid surface. Of course, if the choice of fully automatic operation of the model above problem does not exist. Interfacial tension meter according to the principle can be divided into two kinds: Platinum Circle law and platinum plate method. Platinum Circle method is a traditional test methods, from the invention to the present time about 70 years or so. It is made of platinum wire perimeter of a certain ring. Under the test first platinum loop immersed in the liquid mixture of two incompatible interfaces (or liquid) 2-3mm, then slowly move up the Platinum Circle contact angle measuring instrument, will form a ring with the surface membrane. Film on Platinum Circle will have a pull down force, the entire measurement process film mention the role of platinum loop ring values ??for the maximum force, and then converted into a real interface (surface) tension. History platinum plate method applied to 20 years in a foreign country does not enter the country even more late. Based on surface platinum plate method / interfacial tension meter high technical requirements, manufacturing difficulties, domestic users really been widely used in recent years, with automatic surface or domestic platinum plate method / interfacial tension meter successfully developed and put into the market. Platinum plate method is 24mm × 10mm × 0.1mm platinum plate, the surface blasting roughening treatment, in order to better wetting of the liquid to be measured. When testing the platinum plate lightly touches the interface (or surface) direct contact angle measurement, since the liquid surface tension effects will pull down the platinum plate, when the reverse surface tension of the liquid and other relevant forces and instrument testing When the force equilibrium is reached, the test value is steady, if distilled water, ethanol, a pure substance, the entire testing process fastest only a few seconds.
