Introduction:
The optical contact angle meter is one of the important parameters that can be used to represent the wetting properties of the material surface. The surface energy of the material solid can be obtained through the contact angle. The measurement of contact angles involves a wide range of problems and has important applications in many fields such as industry, agriculture, scientific research, and national defense. Optical contact angle meter application direction: new surface characterization, surface purity testing, solid surface treatment evaluation, liquid formulation design, surface cleanliness analysis, plasma cleaning effect analysis, solid-liquid or solid viscosity characteristics, surface printing performance characterization, Surface wettability of glass (including solids such as plastics or metals), analysis of surface modification, etc.
