Wetting (Wetting) is the phenomenon by which the solid interface changes from a solid-gas interface to a solid-liquid interface. Whereas wettability (wettability) refers to the ability or tendency of a liquid to spread on a solid surface. Wettability of a solid is expressed in terms of contact angle, and when a liquid drop is dropped on the surface of the solid, different wettability can occur in different shapes. The angle between the tangent of the drop at the solid-liquid contact edge and the solid plane is called the contact angle. The contact angle is at least 0 DEG and at most 180 deg. The smaller the contact angle, the better the wettability of the powder. Theta is 0, the liquid completely wets the solid surface, and the liquid spreads on the solid surface; 0< theta <90 deg., the liquid can wet the solid, and the smaller theta, the better the wettability; 90 ° < θ <180 °, liquid cannot wet solid; and theta is 180 degrees and is not wetted completely, and the liquid is condensed into small balls on the surface of the solid.
