The principle of overview
Contact Angle refers to the level of a solid plane drops of a droplet and solid on the surface of the solid - liquid - gas three-phase junction, the gas-liquid interface and the solid-liquid interface two tangent to clamp the liquid phase in the Angle.
Contact Angle measurement instrument, it is mainly used for measuring contact Angle of liquid to solid, namely the infiltrating liquid to solid, the instrument can measure the contact Angle of various kinds of liquid for various materials.The equipment for oil, printing and dyeing, medicine, spraying, mineral processing industries of scientific research production has a very important role.
When droplets freely in space when not the influence of the stress field due to the presence of interfacial tension and a round ball.But, when the droplets and solid surface contact, its final shape depends on the droplet internal cohesion and adhesion force between the droplets and solid relative size.When a droplet is placed on the solid surface and droplets can automatically spreading in solid surface, or in contact with the solid surface with a certain Angle of the droplets.

所谓接触角是指在一固体水平平面上滴一液滴，固体表面上的固－液－气三相交界点处，其气－液界面和固－液界面两切线把液相夹在其中时所成的角。
接触角测量仪，主要用于测量液体对固体的接触角，即液体对固体的浸润性，该仪器能测量各种液体对各种材料的接触角。该仪器对石油、印染、医药、喷涂、选矿等行业的科研生产有非常重要的作用。
当液滴自由地处于不受力场影响的空间时，由于界面张力的存在而呈圆球状。但是，当液滴与固体平面接触时，其最终形状取决于液滴内部的内聚力和液滴与固体间的粘附力的相对大小。当一液滴放置在固体平面上时，液滴能自动地在固体表面铺展开来，或以与固体表面成一定接触角的液滴存在。
