Title:
METHOD FOR MEASURING ADHERENCE STRENGTH OF COAT
Document Type and Number:
Japanese Patent JP2023004050
Kind Code:
A
Abstract:
To provide a method for measuring adherence strength of a coat, capable of directly and accurately measuring adherence strength of a coat in which a fluid layer is formed under a top dryness layer.SOLUTION: When adherence strength of a coat in which a fluid layer is formed under a top dryness layer is measured, a measurement device 1 that sets a force in a vertical direction to be acted on a cutting blade 100 with weight of a weight and can measure a horizontal force acting on the cutting blade 100 is used. First, while using a first weight to apply a force in a vertical direction to the cutting blade 100, the cutting blade 100 is made to carry out biaxial motion until the tip end of the cutting blade 100 reaches the surface of a base material B. Then, a second weight having minimum weight capable of maintaining a contact state between the tip end of the cutting blade 100 and the surface of the base material B is used to horizontally move the cutting blade while applying a force in a vertical direction to the cutting blade 100. A horizontal force at this time is then measured.SELECTED DRAWING: Figure 1
