Abstract

The invention discloses a 3D contact angle test device and method using a polygon prism reflective light path, and belongs to the technical field of a contact angle measuring device. The device comprises an electric control box, a bottom plate, a first vertical connecting plate, a transverse connecting plate, a second vertical connecting plate, a step motor controlled optical rotating platform, aregulating platform assembly, an injection system, a support frame, a camera, a microscope and a polygon prism 3D contact angle lens, wherein the electric control box is provided with a background light source; the microscope is matched with the camera to be used; the polygon prism 3D contact angle lens comprises an installing seat, an installing frame, a plurality of first right-angle prisms anda second right-angle prism; the injection system is rotationally connected with the support frame through a turning support frame. The goal of synchronously and fast testing the 3D contact angle is achieved; the precision of the contact angle test is greatly improved; through the AOI technology, for the profile of each liquid drop, the 3D contact angle value is obtained through the ADSA-RealDrop algorithm.

Description

technical field [0001] The invention relates to a 3D contact angle testing device and method using a polygonal mirror to refract an optical path, and belongs to the technical field of contact angle measuring devices. Background technique [0002] Basic indicators such as liquid-liquid interfacial tension, liquid-gas surface tension, and solid-liquid contact angle are the basic parameters to characterize the physical and chemical properties of substances. The contact angle refers to the point where a small drop of liquid is dropped on a solid horizontal plane, and at the solid-liquid-gas three-phase junction point on the solid surface, the two tangent lines of the gas-liquid interface and the solid-liquid interface sandwich the liquid phase angle formed when . The contact angle value is an indicator comprehensively determined by various factors such as the inherent properties of the material itself, chemical isomerism, surface physical structure, and surface cleanliness.
