(1) bond force. Cohesive force usually refers to the force of the interface between the adhesive and the surface of the bonded object. Wallpaper adhesive with good adhesion is easy to stick wallpaper and hard to tear off. When we buy wallpaper glue, we can make the staff try sticky glue. Maybe we can try stickiness directly with our hands.

(2) viscosity. Viscosity is a concept used to measure the magnitude of internal drag in viscous liquids. In daily life, viscosity is "sticky". For example, we often say that water is "thin", that is, low viscosity. Briefly speaking. We can go through a brief survey to compare the viscosity of the glue.

 ① activity comparison. The less viscous fluid, the better the activity, so in the selection of bottled glue, we can directly reverse two bottles of glue, which is faster and faster than "dilute".

  ②Test of viscosity value. Otherwise, many wall paper adhesives on the market will be labeled with viscosity values. When consumers choose to buy, they can look directly at the reverse side of the package.

Generally speaking, the sticky value of the wallpaper viscosity reaches 20000 MPa. S (viscosity unit: milli Pascal seconds), and the sticky rice glue that reaches 50000 MPA / s should reach the viscosity of the heavy wallpaper wallpaper.
