Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! On the solid surface of the solid - liquid - gas at the point of the three-phase bordered by gas - liquid interface and the solid - liquid interface between two tangents to the liquid interposed therebetween is formed when the angle is called contact angle. In the industrial production process, usually completed using a contact angle measuring instrument interface directly antennae accurate measurements. A brief description of the commonly used measurement methods and related operating requirements below. JC2000X series refers to the large platform (such as 52-inch LCD screen can not be cut test, you need 1200 × 900mm platform), you need a special dedicated test platform and structure jy2 contact angle measuring instrument, usually two to understand customer demand for custom: a, platform size; b, platforms need to test points. (Requires test platform section points or edges than required test platform for all points cheaper), for example AU Optronics, Rainbow shares. The contact angle measuring instrument for measuring the contact angle of a liquid on a solid, namely liquid wettability of solid contact angle measuring instrument can measure a variety of liquid contact angle on a variety of materials. Contact angle measurement instrument for petroleum, printing and dyeing, pharmaceutical, coating, mineral processing and other industries research and production has a very important role. The contact angle is defined as the gas, liquid and solid at the intersection by gas - liquid interface tangent and solid - liquid junction angle θ between the lines, is a measure of the degree of wetting. If θ90 °, then the solid is liquid repellent, the liquid does not wet the solid that is easy to move on the surface and can not enter the pores. Wetting process and interfacial tension system related. A drop of the liquid level falling on the solid surface, when equilibrium is reached, subject to the following contact angle formed between each of the interfacial tension and the Young's equation (Young Equation): γs, g = γs powder contact angle meter, l + γg, l × cosθ can be predicted by its wetting following several situations: 1) when θ = 0, to completely wet; 2) when θ <90 °, part of the wetting or wetting; 3) when θ = 90 °, the run Wet or not the boundary; and 4) when θ> 90 ° contact angle measurement, non-wetting; 5) When θ = 180 °, completely non-wetting. A capillary phenomenon of the liquid rising, falling height h. h represents the sign of the rise or fall. Infiltration of liquid rises, the contact angle is an acute angle; non-wetting liquid drop, the contact angle is an obtuse angle. Rising height h = 2 * surface tension coefficient / (liquid density * gravitational acceleration g * surface radius R). Rising height h = 2 * surface tension coefficient * cos contact angle / (liquid density * gravitational acceleration g * capillary radius r). Wettability problems with mining flotation, oil, textile, pesticide processing, photographic film production, as well as waterproof paint formulations, washing and so closely related. The contact angle of existing test methods are usually two: one for the shape of the image analysis method; the other for the gravimetric method which is often referred to as a wetting balance or osmosis contact angle meter, but the most widely used, the measured value is best direct and accurate image analysis method or appearance.
