BGD190 Contact Angle Measuring Instrument
مقدمة: Contact Angle, it refers to the tangent line of gas-liquid interface at the intersection of gas, liquid and solid phases. The tangent angle θ between the tangent line on liquid side and the solid-liquid boundary.
BGD190 Contact Angle Measuring Instrument is mainly composed of five parts: light source, injection unit, sample table, acquisition system and analysis software. The equipment adopts the principle of optical imaging and measures the following parameters by image profile analysis.
◆The wetting behavior of liquid on solid surface, مثل الانتشار, infiltration, absorption, إلخ. The static contact angle is measured by sessile drop method.
◆Measurement of advancing contact angle(ACA), receding contact angle(RCA), contact angle lag, rolling angle(tilt platform is required) and dynamic contact angle of material on solid surface.
◆Continuous real-time study and process record of absorbing materials, analysis of contact angle variation curve with time.
◆Contact angle measurements of various special materials, such as powders, curved surfaces, super hydrophobic/ super hydrophilic samples.
◆Test of the contact angle of the material immersed in the liquid by the attachment drop method(quartz sample cell is required).
◆Measurement of surface tension, polarity and dispersion components of various liquid meters by pendant drop method.
◆Count surface free energy and analysis of polar dispersion components.
◆Analyze the adhesion of liquid on solid surface, evaluate the uniformity and cleanliness of solid surface, إلخ.
