Abstract

The invention discloses a coating bonding force double-lever measuring device and a measuring method thereof, which include a bracket, a first lever mechanism and a second lever mechanism; the first lever mechanism includes a first screw rod and a beam, and the beam is connected with a second lever mechanism. A base, one side of the first screw rod is provided with a starting point mark and a travel code, and the other side of the first screw rod is provided with a first pull rod; the second lever mechanism includes a second lever and a second pull rod, and the second lever is vertically A fixed seat is provided to the direction, a probe is installed at the lower end of the fixed seat, and a horizontal movement mechanism is arranged below the probe. The invention provides the probe with a linearly increasing load through the double lever system, and moves the probe until the coating cracks and exposes the substrate, and then observes the position of the coating crack, and determines the corresponding load to measure the interface bonding force ; At the same time, the structure is simple and the cost is lower; the operation process is simple during measurement, which is beneficial to the operation of ordinary personnel, and the display effect is obvious.

Description

technical field [0001] The invention relates to the technical field of coating bonding force measurement, in particular to a double-lever measuring device and method for coating bonding force. Background technique [0002] The service life of the coating material largely depends on whether the interface between the coating and the substrate is well bonded, which requires quantitative characterization of the mechanical properties of the interface between the coating and the substrate, but due to the diversity of coating varieties and preparation techniques , so far no unified characterization parameters and testing methods have been formed. In order to measure the interfacial bonding strength between the coating and the substrate, commonly used measurement methods include tensile, shear, bending, scratch, indentation and dynamic testing. [0003] There are two types of stretching methods, namely "transverse stretching method" and "vertical stretching method". The transverse...
