[0002] An adhesive strength tester is an instrument with tensile properties, tear resistance, and heat-sealing strength properties. Adhesive strength testers usually use hydraulic or mechanical loading to apply a certain tension or pressure to the material being tested until the bonding part is damaged. By measuring the force value at the time of damage and combining it with parameters such as the bonding area, the bonding strength can be calculated. When testing the bonding strength between tiles and walls, the fixture of the tester clamps the tiles and then gradually applies tension. When the tiles fall off the wall, the tension value at this time is recorded, and the bonding strength is then calculated.
