Mercury droplets shrink on the glass into an oval, water droplets on the glass to form a slightly convex central thin layer, the former is wet, the latter is not wet phenomenon. Moisture phenomenon is a manifestation of molecular force, if the gravitation between liquid molecules is less than the gravitation between the liquid and the solid, the liquid will wet the solid and the liquid will be evenly coated on the solid surface; if the liquid molecules The gravitation between the liquid and the solid is larger than the gravitation between the liquid, the liquid can not wet the solid, the liquid coated on the solid surface will shrink into a mass.

All liquids each wet some solids and not others. The tangent of liquid surface and the solid surface tangent angle between the contact angle, the contact angle of less than 90 ° liquid wet solid, greater than or equal to 90 ° liquid does not wet the solid.

Copper Enameled Wire surface bright and clean, you can paint a layer of paint, if the surface stained oil, affecting the contact angle between the enameled wire and the paint interface between the two, paint liquid to the wire from wet to not wet. If the copper hard, irregular surface molecular lattice arrangement of the gravitational pull on the small, is not conducive to paint the wet copper wire.
